Juvenile hypothyroidism among two populations exposed to radioiodine. (1/207)

We found an epidemic of juvenile hypothyroidism among a population of self-defined "downwinders" living near the Hanford nuclear facility located in southeast Washington State. The episode followed massive releases of 131I. Self-reported data on 60 cases of juvenile hypothyroidism (<20 years of age) among a group of 801 Hanford downwinders are presented, as well as data concerning the thyroid status of approximately 160,000 children exposed to radioiodine before 10 years of age as a result of the 26 April 1986 Chernobyl explosion in the former Soviet Union. These children were residents of five regions near Chernobyl. They were examined by standardized screening protocols over a period of 5 years from 1991 to 1996. They are a well-defined group of 10 samples. Fifty-six cases of hypothyroidism were found among boys and 92 among girls. Body burdens of 137Cs have been correlated with hypothyroidism prevalence rates. On the other hand, the group of juvenile (<20 years of age) Hanford downwinders is not a representative sample. Most of the 77 cases of juvenile hypothyroidism in the Hanford group were diagnosed from 1945 to 1970. However, the ratio of reported cases to the county population under 20 years of age is roughly correlated with officially estimated mean levels of cumulative thyroid 131I uptake in these counties, providing evidence that juvenile hypothyroidism was associated with radioiodine exposures. Because even subtle hypothyroidism may be of clinical significance in childhood and can be treated, it may be useful to screen for the condition in populations exposed to radioiodine fallout. Although radiation exposure is associated with hypothyroidism, its excess among fallout-exposed children has not been previously quantified.  (+info)

Fibroblast radiosensitivity measured using the comet DNA-damage assay correlates with clonogenic survival parameters. (2/207)

A study was made of the neutral comet assay as a potential method for measuring normal cell radiosensitivity. Eleven fibroblast strains were studied comprising nine derived from vaginal biopsies from pretreatment cervical cancer patients and two strains from radiosensitive individuals. DNA double strand break (dsbs) dose-response curves for both initial and residual (20-h repair time) damage were obtained over the dose range 0-240 Gy, with slopes varying 3.2 and 8-fold respectively. Clonogenic cell survival parameters were available for all the cell strains following both high- and low-dose rate irradiation. There were no correlations between the dose-response slope of the initial level of DNA dsbs and parameters that mainly describe the initial portion of clonogenic radiation survival curves (SF2, alpha, D). A significant correlation (r = -0.63, P = 0.04) was found between the extent of residual DNA dsbs and clonogenicity for all 11 fibroblast strains. The parameter showing the highest correlation with fibroblast cell killing (D) for the nine normal fibroblasts alone was the ratio of initial/residual DNA dsb dose-response slope (r = 0.80, P = < 0.01). A significant correlation (r = -0.67, P = 0.03) with clonogenic radiosensitivity was also found for all 11 cell strains when using the ratio of initial/residual DNA dsb damage at a single dose of 180 Gy. This study shows that fibroblast radiosensitivity measured using the neutral comet assay correlates with clonogenic radiation survival parameters, and therefore may have potential value in predictive testing of normal tissue radiosensitivity.  (+info)

Activation of the CD95 (APO-1/Fas) pathway in drug- and gamma-irradiation-induced apoptosis of brain tumor cells. (3/207)

Chemotherapeutic agents and gamma-irradiation used in the treatment of brain tumors, the most common solid tumors of childhood, have been shown to act primarily by inducing apoptosis. Here, we report that activation of the CD95 pathway was involved in drug- and gamma-irradiation-induced apoptosis of medulloblastoma and glioblastoma cells. Upon treatment CD95 ligand (CD95-L) was induced that stimulated the CD95 pathway by crosslinking CD95 via an autocrine/paracrine loop. Blocking CD95-L/receptor interaction using F(ab')2 anti-CD95 antibody fragments strongly reduced apoptosis. Apoptosis depended on activation of caspases (interleukin 1beta-converting enzyme/Ced-3 like proteases) as it was almost completely abrograted by the broad range caspase inhibitor benzyloxycarbonyl-Val-Ala-Asp-fluoromethyl ketone. Apoptosis was mediated by cleavage of the receptor proximal caspase FLICE/MACH (caspase-8) and the downstream caspase CPP32 (caspase-3, Apopain) resulting in cleavage of the prototype caspase substrate PARP. Moreover, CD95 was upregulated in wild-type p53 cells thereby increasing responsiveness towards CD95 triggering. Since activation of the CD95 system upon treatment was also found in primary medulloblastoma cells ex vivo, these findings may have implications to define chemosensitivity and to develop novel therapeutic strategies in the management of malignant brain tumors.  (+info)

Regulation of the human poly(ADP-ribose) polymerase promoter by the ETS transcription factor. (4/207)

Ewing's sarcoma (EWS) cells accumulate elevated steady-state levels of poly (ADP-ribose) polymerase (PARP) mRNA and protein. To understand the molecular mechanisms underlying PARP upregulation, we cloned and analysed the 5'-flanking region of the PARP gene from EWS cells. Nucleotide sequence analysis demonstrated no variations in the PARP promoter region in EWS cells. The PARP promoter encompasses multiple binding motifs for the ETS transcription factor. We have also observed that there is a coordinated up-regulation of the expression of both PARP and ETS1, relative to cells of other human tumor types expressing lower levels of PARP. Transient co-expression of ETS1 in EWS cells resulted in a strong enhancement of PARP-promoter activity. The participation of ETS in the regulation of PARP gene expression was further demonstrated in EWS cells stably transfected with Ets1 antisense cDNA constructs. Antisense-mediated down-regulation of endogenous ETS1 resulted in the inhibition of PARP expression in EWS cells, and sensitized these cells to ionizing radiation. These data provide support for ETS regulation of PARP expression levels, and implicate ETS transcription factors in the radiation response of EWS cells.  (+info)

Clinical evaluation of processing techniques for attenuation correction with 137Cs in whole-body PET imaging. (5/207)

Transmission scanning can be successfully performed with a 137Cs single-photon emitting point source for three-dimensional PET imaging. However, the attenuation coefficients provided by this method are underestimated because of the energy difference between 662- and 511-keV photons, as well as scatter and emission contamination when the transmission data are acquired after injection. The purpose of this study was to evaluate, from a clinical perspective, the relative benefits of various processing schemes to resolve these issues. METHODS: Thirty-eight whole-body PET studies acquired with postinjection singles transmission scans were analyzed. The transmission images were processed and applied to the emission data for attenuation correction. Three processing techniques were compared: simple segmentation (SEG) of the transmission scan, emission contamination subtraction with scaling (ECS) of the resulting data to 511-keV attenuation coefficient values and a hybrid technique performing partial segmentation of some tissue densities on the ECS scan (THR). The corrected emission scans were blindly assessed for image noise, the presence of edge artifacts at the lung-soft-tissue interface and for overall diagnostic confidence using a semiquantitative scoring system. The count densities and the SDs in uniform structures were compared among the various techniques. The observations for each method were compared using a paired t test. RESULTS: The SEG technique produced images that were visually less noisy than the ECS method (P < 0.0001) and the THR technique, but at the expense of increased edge artifacts at the boundaries between the lungs and surrounding tissues. The THR technique failed to eliminate these artifacts compared with the ECS technique (P < 0.0001) but preserved the activity gradients in the hilar areas. The count densities (and thus, the standardized uptake values) were similar among the three techniques, but the SEG method tended to underestimate the activity in the lung fields and in chest tumors (slope = 0.79 and 0.94, respectively). CONCLUSION: For many clinical applications, SEG data remain an efficient method for processing 137Cs transmission scans. The ECS method produced noisier images than the other two techniques but did not introduce artifacts at the lung boundaries. The THR technique, more versatile in complex anatomic areas, allowed good preservation of density gradients in the lungs.  (+info)

Environmental radioactivity, population exposure and related health risks in the east Baltic region. (6/207)

The paper considers radioactive contamination of the east Baltic region, population exposures, and the risk of damage to human health. Principal sources include global fallout, the Chernobyl accident, and marine transport of radionuclides. A mean annual exposure of 2-3 mSv comes from environmental radioactivity. Main contributors are primarily radon and its decay products. The Chernobyl accident brought an additional dose of about 0.5 mSv in southern Finland and 1.4 mSv in the most contaminated districts of the Leningrad region, Russia. Both external and internal exposure via contaminated food contributed. Currently, significant long-term radiological consequences of the Chernobyl accident include persistent radioactive contamination of natural terrestrial (forest) and freshwater (oligotrophic lakes) ecosystems and food products. Radiation health risks are lung cancer among the general population from indoor exposure to radon, acute radiation syndrome from occupational exposure, thyroid cancer among children in heavily contaminated non-Baltic areas, and mutations among offspring of exposed parents.  (+info)

Remote afterloading endocurie therapy for carcinoma of the cervix. (7/207)

Since October 1975, 41 cancer patients were treated with a remote afterloading device using fractionated high dose-rate intracavitary radiation. Nineteen of these 41 patients were treated for carcinoma of the cervix. Remote afterloading high dose-rate fractionated intracavitary radiation was given in combination with external irradiation. The dose fractionation and rad equivalent therapeutic (RET) values and various points of interest are discussed.  (+info)

Radiation-induced apoptosis of endothelial cells in the murine central nervous system: protection by fibroblast growth factor and sphingomyelinase deficiency. (8/207)

Injury to the central nervous system (CNS) by ionizing radiation may be a consequence of damage to the vascular endothelium. Recent studies showed that radiation-induced apoptosis of endothelial cells in vitro and in the lung in vivo is mediated by the lipid second messenger ceramide via activation of acid sphingomyelinase (ASM). This apoptotic response to radiation can be inhibited by basic fibroblast growth factor or by genetic mutation of ASM. In the CNS, single-dose radiation has been shown to result in a 15% loss of endothelial cells within 24 h, but whether or not this loss is associated with apoptosis remains unknown. In the present studies, dose- and time-dependent induction of apoptosis was observed in the C57BL/6 mouse CNS. Apoptosis was quantified by terminal deoxynucleotidyl transferase-mediated nick end labeling, and specific endothelial apoptosis was determined by histochemical double labeling with terminal deoxynucleotidyl transferase-mediated nick end labeling and Lycopersicon esculentum lectin. Beginning at 4 h after single-dose radiation, apoptosis was ongoing for 24 h and peaked at 12 h at an incidence of 0.7-1.4% of the total cells in spinal cord sections. Up to 20% of the apoptotic cells were endothelial. This effect was also seen in multiple regions of the brain (medulla, pons, and hippocampus). A significant reduction of radiation-induced apoptosis was observed after i.v. basic fibroblast growth factor treatment (0.45-4.5 microg/mouse). Identical results were noted in C3H/HeJ mice. Furthermore, irradiated ASM knockout mice displayed as much as a 70% reduction in endothelial apoptosis. This study demonstrates that ionizing radiation induces early endothelial cell apoptosis throughout the CNS. These data are consistent with recent evidence linking radiation-induced stress with ceramide and suggest approaches to modify the apoptotic response in control of radiation toxicity in the CNS.  (+info)

Contaminants Released, Chernobyl. "A retrospective view of the Chernobyl accident of Apr 26, 1986 assesses the total radiation release at about 100 megaCuries or 4 x 1018 becquerels, including some 2.5 MCi of cesium-137. The cesium is the most serious release in terms of long term consequences. The total release was around 4% of the total accumulated activity of the core and compares to a release of 15 Ci at Three Mile Island. The release was then about 7 million times that at TMI. Anspaugh, et al. suggest that essentially all the noble gases and about half of the volatile elements (iodine-131, cesium-134 and cesium-137) were released. The cesium release from all of the atmospheric weapons tests is estimated to be about 30 MCi. The noble gas releases were estimated by Levi to be 45 MCi of xenon-133 and 5 MCi of krypton-85. About 3-5% of the core inventory of the relatively refractory elements such a strontium, plutonium, and ruthenium were released, much more than from a light water reactor ...

Radioactive fallout from the Chernobyl accident affected parts of central Norway to a considerable extent, in particular the 134Cs+137Cs deposition had a significant impact on the natural environment. When this became apparent, a comprehensive radioecological research programme was initiated in order to study the behaviour of radiocaesium in boreal and alpine ecosystems, with emphasis on food-chains leading to exposure of species used for human consumption, i.e., reindeer and freshwater fish. In this paper results from the terrestrial part of this research programme during the period 1986-1990 are presented. The work was mainly confined to the mountain areas of Dovre and Rondane. Parallel studies were performed in eutrophic and strongly oligotrophic communities. The influence of local variations in topography and microclimate on the observed radiocaesium levels in topsoils, lichens and vascular plants was studied in detail. Currently a significant re-distribution of radiocaesium from the ...

In an unprecedented food monitoring advertising campaign for radionuclides, japan government took action to secure food safety following the Fukushima nuclear incident (Mar. decreased quickly then, once again in Sept 2011 but peaked, which was mainly because of boar meat (a known accumulator of radiocesium). Tap water was less contaminated; any restrictions for tap water were canceled by April 1, 2011. Pre-Fukushima 137Cs and 90Sr levels (resulting from atmospheric nuclear explosions) in meals had been typically less than 0.5 Bq/kg, whereby meat was typically higher in 137Cs and vegetarian generate was usually higher in 90Sr. The relationship of history radiostrontium and radiocesium indicated which the regulatory assumption following the Fukushima incident of a optimum activity of 90Sr getting 10% from the particular 137Cs concentrations may shortly be in danger, as the 90Sr/137Cs proportion increases as time passes. This should be studied into consideration for the existing Japanese meals ...

This might explain the Fuku-denialism & denial of radiation in West Coast waters of the U.S. Controlling interest now held by one individual. Fr. Wikipedia:. In 1994, Westinghouse signed a long-term affiliation deal to affiliate all five of its Group W TV stations with CBS.[113][114] Of the other four stations, two of the stations (KPIX in San Francisco and KDKA-TV in Pittsburgh) had been decades-long affiliates of the network, while KYW-TV in Philadelphia and WBZ-TV in Boston were NBC affiliates. The network decided to sell off existing O&O WCAU, which would eventually be purchased by NBC, despite at the time being much higher rated locally than KYW-TV. While WJZ-TV and WBZ-TV switched to CBS in January 1995, the swap was delayed in Philadelphia when CBS discovered that an outright sale of channel 10 would have forced it to pay massive taxes on the proceeds from the deal.

Description: Crystalline silicotitanate (CST) is an ion-exchange method for removing radioactive cesium from tank waste to allow the separation of the waste into high- and low-level fractions. The CST, originally developed Sandia National Laboratories personnel in association with Union Oil Products Corporation, has both a high affinity and selectivity for sorbing cesium-137 from highly alkaline or acidic solutions. For several years now, the U.S. Department of Energy has funded work to investigate applying CST to large-scale removal of cesium-137 from radioactive tank wastes. In January 1997, an expert panel sponsored by the Tanks Focus Area met to review the current state of the technology and to determine whether it was ready for routine use. The review also sought to identify any technical issues that must be resolved or additional CST development that must occur before full implementation by end-users. The CST Gate Review Group concluded that sufficient work has been done to close ...
Watch the Video. In 1998, a company co-founded by Pacific Northwest National Laboratory (PNNL) retiree Lane Bray, an internationally recognized expert in medical isotopes, came to PNNL for technical assistance. The company, IsoRay Medical, Inc., now produces Cesium-131 radiochemical brachytherapy seeds used in facilities across the country to treat prostate and other cancers. The Cesium-131 seed offers a significantly shorter half-life than the two other isotopes commonly used for brachytherapy, allowing faster delivery of therapeutic radiation to the prostate gland, reduced incidence of common brachytherapy side effects, and lower probability of cancer cell survival. IsoRay literally started in Lane Brays basement, with about three employees, said Larry Greenwood, the Pacific Northwest National Laboratory (PNNL) technical lead for the IsoRay project.

To this day, the settlements closest to the reactor site remain depopulated ghost towns; however, the explosion sent a radioactive cloud over most of Europe, and many regions received a fallout level that, while not quite serious enough to require permanent evacuation, is still more than enough to blight local ecosystems and human communities with radiation poisoning. 110 miles away is the region of Bryansk, of which nearly 2 million acres received a heavy dose of fallout pollution, primarily Cesium-137. Hundreds of thousands of people still inhabit this largely agricultural area, and the greatest danger they face is the ingestion of radioactive particles (or radionuclides) that have accumulated in the meat, fat, and milk of local cattle, as well as the produce from local farms and gardens. In some provinces over 20% of all dairy milk is dangerously contaminated. ...
3.2 Internal Exposure Monitoring. Personnel who work at workplaces or environment of which the present of unseal sources or contamination is confirmed are required to undergo internal exposure monitoring. Working with contaminated environment and improper way of working with unsealed sources might lead to intake of the radioactive material which results in internal contamination. The ingress of radioactive materials into the body is through ingestion, inhalation, skin and open wound. In order to assess the intake of radioactive substance in the body, a special instrumentation is used.. Two common methods used to measure internal contamination are direct method and indirect method. Direct method commonly used in whole body counter while indirect method in bioassay. Direct method is a method where the radiation dose is measured directly using measuring instruments. In the other hand, indirect method will require samples namely urine, faeces or sweat. These samples will be analyse in laboratory to ...

There are examples of this type of complex conundrum in nature, in such things as trying to solve 22/7 (which is a never-ending decimal), and in determining the halflives of certain radioactive materials (isotopes), where one half of the material loses its radioactive potency over a certain period of time, but the residual amount keeps getting halved and never quite disappears. ...
Photo : Wikipedia. From Tepcos fish contamination report released on 7/18/2014, 370 Bq/Kg of Cesium-134 / 137 was measured from fish outside of Fukushima plant port.. Its "Okamejei", a type of ray fish. The sampling date was 6/15/2014.. Tepco reports it was fished approx. 4km offshore of Kumagawa-river. It is assumed to be 5~6 km from Fukushima plant port.. Also 178 Bq/Kg of Cesium-134/137 was measured from another Okamejei sample taken outside of Fukushima plant port.. It is not clear how many other measurement results are covered up, however at least it is shown that Fukushima plant is still contaminating the creatures outside of its port.. http://www.tepco.co.jp/nu/fukushima-np/f1/smp/2014/images/fish02_140718-j.pdf. ...
Radioactive cesium from the 2011 Fukushima disaster is still being detected in citrus and other plants as far away as Florida, according to a report sent to the U.S. Nuclear Regulatory Commission (NRC). In March 2011, multiple nuclear meltdowns took place at the Fukushima Daiichi plant in Japan. The explosions ejected massive amounts of radioactive material into the environment, most notably radioactive cesium isotopes. In the weeks after the disaster, winds carried airborne radionuclides to every corner of the globe. Most of the radioactivity, however, settled into the Pacific Ocean.The report is Duke Energy Floridas Annual Radiological Environmental Operating Report to U.S. NRC, dated May 5. It notes that immediately following the Fukushima disaster, radioactive iodine and cesium from the plant were detected in Florida vegetation. "The Japanese event also affected broad leaf vegetation sample media throughout the year as long-lived radionuclides (Cs-137) were released at Fukushima multiple ...

Dear friends: Since the Fukushima nuclear power plants accident in March 2011, there have been two types of contributions by nuclear scientists. One type, who represents the voice of TEPCO, has influenced the decision makers of the solutions to the accident, the government strategy of the evacuation zone, the timing of announcement of the core meltdown and the constant public campaign to give the impression that the situation is improving rapidly. The other type, who has been warning the government of the worsening situation, finds their influence over the decision makers and the media circle limited. However, I find it puzzling that there has been so little warning from the nuclear community about the potential for catastrophic accidents or terrorist attack involving the hundreds of spent fuel pools worldwide. I received a clear explanation from Dr. Gordon Edwards, one of Canadas best known independent experts on nuclear technology, uranium, and weapons proliferation. I hope you will better ...

An experiment was carried out to provide a data set specifically designed to allow the development of a model to describe the dynamic behaviour of radiocaesium in sheep tissues. A single intraruminal dose of 134CsCl was given to each of 15 Scottish Blackface ewes, aged 1-2 years. Radiocaesium activity concentrations were measured at various time intervals after dosing in blood, faeces and urine and, after slaughter, in a range of tissues and digestive tract contents. A first order compartment model was developed comprising nine compartments representing various organs and tissues in the body. Rate constants for the model were obtained by optimisation to the experimental results. A limited validation of the model was carried out by using it to calculate tissue transfer coefficients (Ff) and biological half-lives (0.5) of radiocaesium in sheep. The values generated compare favourably with published figures. Applications for the model and constraints on its usage are examined along with ...

The researchers insisted that the levels detected so far are not high enough to be particularly dangerous to humans or marine life. "As an example, even if they were twice as high and I was to swim there every day for an entire year, the dose I would be exposed to is a thousand times less than a single dental X-ray," Buesseler said.. "So the risk [from radiation exposure] is never zero, but when I think of health risk, I always think of the Japanese side of the Pacific instead of ours.". Radioactive cesium from the Fukushima disaster is likely to keep arriving at the North American coast, he said. "Predicting the spread of radiation becomes more complex the closer it gets to the coast.". According to a 2013 study by the Nansen Environmental and Remote Sensing Center in Norway, the main part of the radioactive ocean plume from the Fukushima disaster is likely to hit the North American west coast in 2017, with maximum concentrations of radioactivity arriving in 2018. The model showed the bulk of ...
Despite a lack of widespread media coverage and TEPCOs reassurances that things are under control, there is concern that the nuclear disaster at Fukushima - already one of the worst nuclear disasters in human history - is quickly growing even worse.. PBS News reported last year that more than 80 percent of the radioactivity from the three damaged reactors was released into the Pacific Ocean, as 300 tons of radioactive water have leaked from the reactors every day since an earthquake and subsequent tsunami crippled the plant in 2011.. The Pacific Ocean may have diluted much of the radiation, due to its massive volume, yet radiation and debris from the disaster have been detected along the western coast of Canada and the United States. Traces of Fukushima radiation were first detected in early 2015, when trace amounts of cesium-134 and cesium-137 appeared in samples collected near Vancouver Island. Then, in December of last year, researchers at the Woods Hole Oceanographic Institution detected ...

Ken Buesseler, senior scientist in marine chemistry & geochemistry at the Woods Hole Oceanographic Institution: It actually surprised us a bit this summer when they said [the Fukushima Daiichi site is] not leaking into the ocean, and they said its not getting out of the harbor. Anyone offshore can detect those isotopes. It is leaking, continuously at low levels of cesium, compared to the release - nothing like the 100 of, or 50 to 80 petabecquerels in 2011. ...

In an unprecedented food monitoring campaign for radionuclides, the Japanese government took action to secure food safety after the Fukushima nuclear accident (Mar. 11, 2011). In this work we analyze a part of the immense data set, in particular radiocesium contaminations in food from the first year after the accident. Activity concentrations in vegetables peaked immediately after the campaign had commenced, but they decreased quickly, so that by early summer 2011 only a few samples exceeded the regulatory limits. Later, accumulating mushrooms and dried produce led to several exceedances of the limits again. Monitoring of meat started with significant delay, especially outside Fukushima prefecture. After a buildup period, contamination levels of meat peaked by July 2011 (beef). Levels then decreased quickly, but peaked again in September 2011, which was primarily due to boar meat (a known accumulator of radiocesium). Tap water was less contaminated; any restrictions for tap water were canceled ...
SIGNS AND SYMPTOMS/ /ACUTE RADIATION SYNDROME/ Fifty persons involved in the cesium-137 accident in Goiania showed symptoms of whole-body and local acute irradiation and also external or internal contamination mainly due to ingestion or absorption of cesium-137. Fourteen of the 50 developed severe bone marrow depression characterized by neutropenia and thrombocytopenia. Eight of these 14 received GM-CSF intravenously. None were submitted to bone marrow transplantation. Four of the 14 died due to hemorrhage and infection. For those with significant internal contamination evaluated by in-vitro and in-vivo assays, Prussian Blue was administered with doses ranging from 1.5 to 10 g/day. Besides Prussian Blue, other measures were taken to increase decorporation of cesium-137, including administration of diuretics, water overload, and ergometric exercises. From 50 to 100 persons are being followed in a medical protocol ...
The corporate media is again ignoring a major and potentially catastrophic development at the Fukushima nuclear plant in Japan.. Kyodo News reported on March 15 that "that the clarity of water inside the spent fuel pool of the No. 4 unit may have deteriorated based on a survey conducted by a camera," according to Tokyo Electric Power Co., the plant operator.. TEPCO said "visibility in the pool is only about 1 meter, far less than the approximately 7 meters needed to work at removing nuclear fuel from the pool as part of the process of scrapping the four reactors severely damaged by last years nuclear accident.". One month ago, TEPCO was able to see approximately five meters into the spent fuel pool water.. The spent fuel rods pose considerable hazard. In order to reduce "decay heat," the rods must remain submerged in circulating water. If exposed to air, they combust and release large amounts of radioactive cesium-137.. Following the earthquake and tsunami that damaged the Fukushima plant last ...
is on the way.... Nature has an article about it, here are some highlights.. The risk to the roughly 140,000 civilians who had been living within a few tens of kilometres of the plant seems even lower. Because detailed radiation measurements were un available at the time of the accident, the WHO estimated doses to the public, including radiation exposure from inhalation, ingestion and fallout. The agency concludes that most residents of Fukushima and neighbouring Japanese prefectures received a dose below 10 mSv. Residents of Namie town and Iitate village, two areas that were not evacuated until months after the accident, received 10-50 mSv. The government aims to keep public exposure from the accident below 20 mSv per year, but in the longer term it wants to decontaminate the region so that residents will receive no more than 1 mSv per year from the accident.. The WHOs calculations are consistent with several health surveys conducted by Japanese scientists, which found civilian doses at or ...
Infant girls exposed in the worst-affected area also have a 6 percent higher risk of breast cancer, and a 4 percent increase in the risk of developing any solid cancer, according to the report.. A study by Stanford University scientists last year found that radiation from the Fukushima nuclear plant may cause as many as 1,300 cancer deaths globally and as many as 2,500 cases of cancer, mostly in Japan. The WHO said it didnt have estimates on the number of people affected by radiation.. […]. The nuclear plant may have emitted about 900,000 terabecquerels of radiation into the air at the height of the disaster, Tepco said in May. The total radiation release at the 1986 Chernobyl accident in Ukraine was estimated to be about 5.2 million terabecquerels.. The Fukushima accident didnt last as long as that in Chernobyl, the geographic spread of radiation was less, and people were evacuated more quickly from 20 kilometers around the Dai-Ichi plant, Tritscher said. The evacuation was "probably the ...
In February 2014, the number of confirmed and suspected cases of thyroid cancer among people aged 18 or below at the time of the accident rose to 75, compared with 59 at the end of last September. Of the current total, 33 cases have been confirmed as cancer.. Local health authorities have so far tested around 250,000 out of 375,000 Fukushima children and adolescents, who are due to be screened regularly throughout their lives.. Joseph Mangano, epidemiologist and executive director of Radiation and Public Health Project Research Group, did not rule out that the next few years will see more cancer cases among children living in the disaster-hit area.. "The only study I know was held in Japan and it looked at about 200,000 children near Fukushima. Medics from Fukushima Medical University tested childrens thyroid glands because they are very sensitive to such chemicals as iodine. Thyroid cancer among children is very rare, but 72 children with suspected thyroid cancer have already been identified ...

Curative therapies for clinically localized prostate cancer have significant morbidity, and those patients who might be cured by aggressive management are not easily identified using current clinical information. Better biomarkers of tumor behavior need to be identified to improve clinical outcome. Chondroitin sulfate (CS), a glycosaminoglycan, may be a potentially useful biomarker as it is known to influence cell growth and differentiation and might influence malignant progression. In this study, CS was immuno-localized to the periacinar and peritumoral fibromuscular stromal tissue of nonmalignant and malignant prostates. The CS concentration was increased in the prostate tissue of men with early-stage prostate cancer compared with tissue from men without cancer (P , 0.0001). Using Coxs univariate analysis, CS concentration, tumor grade, preoperative serum prostate-specific antigen (PSA), extracapsular extension of disease, positive surgical margins, and patient age were associated with an ...

2014/08/02. The Ministry of the Environment said that its efforts to remove radioactive contamination from Fukushima disaster will shift focus to case-by-case exposure amounts rather than a universal goal, according to a midterm report it released on Aug. 1.. The change was prompted by data showing that despite many local municipalities aiming to lower air radiation levels to within 0.23 microsieverts per hour, there have been numerous cases where even with air radiation levels at between 0.3 and 0.6 microsieverts per hour, peoples yearly exposure to radiation caused by the disaster has stayed below a limit of 1 millisievert of extra radiation exposure per year.. The data, introduced in the report, came from a survey on around 70,000 people by the cities of Date and Soma in Fukushima Prefecture, where people living in areas with 0.3 to 0.6 microsieverts of radiation per hour were still under 1 millisievert of extra radiation exposure per year. The ministry suggested to local municipalities that ...
The adjacent figure shows the activity concentrations of artificial iodine-131 and caesium-137 compared to the activity concentration of natural radioactivity (radon and beryllium-7), measured at Schauinsland station between 21 March and 12 May 2011. During that period the sampling frequency was increased from weekly to daily sampling.. In the sample collected 24 March 2011 (measurement from 25 March 2011) iodine-131 with an activity concentration of 58 microbecquerels per cubic metre of air as well as caesium-137 were detected initially. Subsequently, the artificial nuclides iodine-131, caesium-137 as well as caesium-134 were detected in air filter samples until the middle of May.. After mid-May, the activity concentrations for iodine-131 and caesium-134 were below detection limits, the activity concentration for caesium-137 decreased further and is now at the background level measured before the reactor disaster in Fukushima.. However, caesium-137 is occasionally detected in some samples due ...
As the first featured speaker, Ms. Korsnick provided a comprehensive view of the direct influence that the Fukushima accident has had on the U.S. nuclear energy industry, with emphasis on safety enhancements. Active reactor fuel cooling and controlled venting, she asserted, is the best way to prevent radiation release, and improved training programs have been implemented to educate workers about these safety protocols.. Above all, she stressed, Fukushima taught the industry that no matter what happens, a plant needs water to ensure cooling capacity, and power must always be available to move that water around to maintain stability. To ensure that all U.S. plants can withstand any hypothetical incident, approximately $4 billion is being spent on the implementation of "post-Fukushima learnings," and CNOs from both the U.S. and Japan have strengthened their relationships and exchanges to maximize this impact.. Representatives from the Department of Energy, Damian Peko and Julia Bisconti, were ...

Nothing could be further from the truth. Fukushima Prefecture is very mountainous and became highly contaminated after the triple meltdowns. Those of us who have studied the disaster at Fukushima Daiichi have noted for years that an extraordinary amount of radioactive cesium, strontium, and other radioactive isotopes from three nuclear meltdowns has spread hundreds of miles from the site of the disaster. The rain that lashed the east coast of Japan flooded that radioactive material to new locations downhill. It is obvious to scientists, but not the mainstream media in Japan, that areas that have been previously decontaminated by the Japanese are now contaminated again by the flooding. These newly contaminated areas include villages that had been evacuated when the disaster struck four and a half years ago that the Japanese government has allowed its population to return to ...

nuclear contaminants at the surface will move eastward in the Pacific as far as 140°W, thereafter dividing into two branches. For the south branch, nuclear contaminants will be transported westward by the equatorial current, and can reach the Philippines after 10 years time. In contrast, the north branch will arrive at the American west coast and then migrate to the Bering Sea. At 200 m water depth, part of the nuclear materials will move southwestward along with deep ocean circulation, which could potentially reach the east coast of Taiwan. The other part will move to the west coast of America and separate into two branches. One will move northward along the west coast of Alaska, while the other will travel southward to the Hawaiian Islands. […] The physical dispersion model results show that high concentrations of the radioactive isotope cesium-137 (137Cs) will move eastward and reach the central Pacific and west coast of North America in two and eight years, respectively ...
As it happens, the older collapsing sarcophagus for Chernobyl is being replaced by a brand new enormous steel frame: "Thanks to the sarcophagus, up to 80% of the original radioactive material left after the meltdown remains in the reactor. If it were to collapse, some of the melted core, a lava-like material called corium, could be ejected into the surrounding area in a dust cloud, as a mixture of highly radioactive vapour and tiny particles blown in the wind. The key substances in this mixture are iodine-131, which has been linked to thyroid cancer, and cesium-137, which can be absorbed into the body, with effects ranging from radiation sickness to death depending on the quantity inhaled or ingested," Ibid.

The radiocesium activity in the AMP/Cs compound was measured in the laboratories of the Mutsu Oceanographic Institute/JAMSTEC, Low Level Radioactivity Laboratory/Kanazawa University (LLRL/KU), and the NIRS. In JAMSTEC, the radiocesium was measured with low-background Ge-detectors (Well-type GCW2022-7915-30-ULB, Canberra Industries, Inc.), which were calibrated with gamma-ray volume sources (Eckert & Ziegler Isotope Products) certificated by Deutscher Kalibrierdienst (DKD). The gamma counting time ranged from a day to a week, and 134Cs and 137Cs activities were evaluated from gamma-ray peaks at 605 and 661 keV, respectively. The averages of the detection limits (3 standard deviations) of the 134Cs and 137Cs measurements were calculated to be 0.53 and 0.20 Bq m−3, respectively. In the case of the 605 keV photopeak from 134Cs, the cascade summing effect was corrected. The factor for the summing effect was about 2, which was calculated as the difference between the 134Cs/137Cs ratios at a distance ...
The primary objective of the IAEAs BIOMASS Forest Working Group (FWG) was to bring together experimental radioecologists and modellers to facilitate the exchange of information which could be used to improve our ability to understand and forecast radionuclide transfers within forests. This paper describes a blind model validation exercise which was conducted by the FWG to test nine models which members of the group had developed in response to the need to predict the fate of radiocaesium in forests in Europe after the Chernobyl accident. The outcomes and conclusions of this exercise are summarised. It was concluded that, as a group, the models are capable of providing an envelope of predictions which can be expected to enclose experimental data for radiocaesium contamination in forests over the time scale tested. However, the models are subject to varying degrees of conceptual uncertainty which gives rise to a very high degree of divergence between individual model predictions, particularly ...
The Fukushima disaster caused the largest discharge of radioactivity into the ocean ever seen. At this point after the nuclear disaster however, scientist expected that the radiation levels in the waters surrounding the island would have decreased ever so slightly. Well, it hasnt. In fact, they have stayed "stable" since the SHTF over there. Looks like contaminated sediment in water runoff, hot micro-organism decay in the sand, and "continuing leaks" from the plant are to blame for this steady radiation level. After 18 months, the cesium-137 levels in bottom dwelling fish hasnt changed much either. As such, the radiation is finding itself in the food chain still ...
Paul Stamets, mycologist, suggests using mushrooms to remediate radiation from Fukushima nuclear disaster.

The enormity and unprecedented nature of this combined natural and…
It was mind numbing to learn how much on average each nuclear plant in the US alone has in their spent fuel pools (which were never designed for long term storage) estimated at well over a hundred million curies at each plant of the cesium 137 alone! (1 gram = 88 curies and as little as 1\3 of a gram to 2 grams of this stuff will thoroughly waste a square kilometer of land for a very very long time. Do the math!!).. The fact that this technology was pushed through due to the war effort at the time is mildly understandable, however the aftermath of that day should have scared the poo out of everyone and as a race should have re-examined the entire nuclear concept! When this technology was put in, my parents were never really told the whole story for quite some time and my dad only found out the full extent when he enlisted into the Canadian Navy. A sad but disturbingly real fact that seems to have come to light years later is the governments of both my parents day as well as my own originally ...

An irradiator furnace is connected to a square waveguide for propagation of microwaves and provided through a top wall with a slot. A conveyor bucket conveys sealed containers along the slot with lower portions of the sealed containers being inserted through the slot into the irradiator furnace. The irradiator furnace includes therein a rail which extends from a lower level of the furnace thereof at the inlet thereof to a higher level of the furnace at the outlet so as to support the sealed containers in a vertical direction. A hot air furnace is provided above the irradiator furnace. A narrow passage extending from the outlet of the irradiator furnace is directly followed by a thermostatic station utilizing an IR heater. So the sealed containers are sterilized.
A new study posted for open peer-review suggests that the nuclear reactors at Fukushima Daiichi released far more radiation than the Japanese government initially estimated.

The maximum level of radiation allowed in foods for human consumption is 100 becquerels/kilogram. The murasoi caught inside the 20 kilometer area near the plant - which is closed to humans - registered 254,000 becquerels cesium/kilogram. Again, thats 2,500 times higher than the government-imposed limit. It is also 10 times higher than the radiation measured last August in scorpion fish caught near Fukushima ...

110 miles away, in the region of Bryansk, nearly 2 million acres received a heavy dose of radioactive pollution, primarily Cesium-137. Hundreds of thousands of people still inhabit this largely agricultural area, and the greatest danger they face is the ingestion of radioactive particles (or radionuclides) that have accumulated in the meat, fat, and milk of local cattle, as well as the produce from local farms and gardens. In some provinces over 20% of all dairy milk is dangerously contaminated. Children receive the highest doses of cesium, as they tend to ingest more dairy products than adults and their still-growing bones absorb more pollutants from their food. ...
The SARRP is also used to study the effects of low radiation doses (≤ 2 Gy). The consequences of this type of exposure on brain function and on the related pathophysiological mechanisms are studied through the development of several irradiation models on the facility (highly localized irradiation of certain cerebral sub-structures and of the whole head).. Lastly, the irradiator is used by the IRSN as part of the ROSIRIS program, the purpose of which is to better understand the causal relationship between the early effects and the delayed effects of ionizing radiation on the body. The type of initial radiation-induced cell damage depends on the way in which the energy of an ionizing particle is deposited within a cell, and therefore the physical characteristics of that particle. To analyze the damage, one of the research avenues consists of establishing links between biophysical modeling of early radiation-induced events and their later consequences on molecules and cells, by studying the ...

There are several steps to RIT. Part of the process is to determine if you are a good candidate for the treatment.. An IV will be placed that allows the medication to pass directly into the bloodstream. A monoclonal antibody without radioactive material will be delivered first. This antibody will connect to a specific type of immune cell to protect these healthy cells from the radiation medication. Next, a low dose of radioactive material is infused through the IV. The infusion is delivered slowly over a period of time.. The following week, imaging tests will be done to see where the radioactive material traveled in the body. If the tests determine that RIT has targeted the correct area the next part of the treatment will begin. The monoclonal antibodies with a higher dose of radioactive material will be given by IV in multiple courses in the following weeks. ...
Mr Toru Anzai, 63, wanders around the house he abandoned five years ago [in] Litate… Two years ago, he had a heart attack and a stroke… in the hospital they found a hole in the frontal lobe of his brain that was producing paralysis down the left side of his body. The doctor said it could have been caused by absorbing cesium over a period of time… [After the reactor explosion on] March 14, he heard a thunderous noise… It didnt take long for the wind to bring the penetrating smell of melted iron mixed with sulfur to Litate as a massive toxic cloud blew towards his home. In spite of the mayor of Litates assurance that there was no risk of radiation, Mr Anzai bought his first dosimeter on April 18… the radiation in the room where he and his brothers had been sleeping for the past month was at six microSieverts an hour - 20 times higher than the level stipulated by the government for relocating residents ...

What most people have use for though are Dosimeters you can buy a handheld radiation detector pretty cheap that are good addition to a survival kit. There are different kinds that you can use that will detect radiation. There are radiation badges that will tell you when radiation become high. Workers at nuclear power plants use these to inform them of how much radiation they have been exposed to. Now also children in the Fukushima prefecture have each been given a radiation badge so they know if they are exposed to radiation. Some come in the shape of a pen that you can carry in your pocket while other are made more compact so that you can attach them to your keychain. And then you have what is called a personal radiation monitor. These are also called Dosimeters and also normally called Geiger counters. Although not all use the Geiger-Muller Tube for the radiation detection some use a semiconductor instead. These and mostly the older geiger counters seen are pretty big to carry around, so they ...
Shortly after the accident, J-village, a soccer training facility located 20 km south of Fukushima Dai-ichi NPP, was utilised as a place for preparing workers for entry into the nuclear power station, where they put on their protective equipment and performed decontamination tests when leaving (figure 2). Accommodation facilities for workers were set up outside the 20 km evacuation zone. Inside the Fukushima Dai-ichi NPP, the main earthquake-proof building, in which radiation exposure was controlled by a high-quality purified-air ventilation system, was set up as a direct command centre for operations and had some rooms for workers to stay overnight.. Several measures were taken to prevent external and internal radiation exposure. To minimise external exposure, the radiation level was assessed over the whole site, and workers monitored radiation exposure using an alarm pocket dosimeter. To protect workers from internal radiation exposure from inhaling radioactive particles and gas, workers wore ...
The devastating tsunami triggered by the Great East Japan Earthquake on March 11, 2011 inundated the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) resulting in a loss of cooling and a series of explosions releasing the largest quantity of radioactive material into the atmosphere since the Chernobyl nuclear accident. Although 80% of the radionuclides from this accidental release were transported over the Pacific Ocean, 20% were deposited over Japanese coastal catchments that are subject to frequent typhoons. Among the radioisotopes released during the FDNPP accident, radiocesium (134Cs and137Cs) is considered the most serious current and future health risk for the local population. ...
Title: RADIOACTIVE WASTE MANAGEMENT IN THE CHERNOBYL EXCLUSION ZONE - 25 YEARS SINCE THE CHERNOBYL NUCLEAR POWER PLANT ACCIDENT. Author: Farfan, E. / Jannik, T.. Reference: HEALTH PHYSICS JOURNAL, 2011. Keywords: Radioactive waste, Chernobyl, ChNPP accident, Chernobyl Exclusion Zone. Abstract: Radioactive waste management is an important component of the Chernobyl Nuclear Power Plant accident mitigation and remediation activities of the so-called Chernobyl Exclusion Zone. This article describes the localization and characteristics of the radioactive waste present in the Chernobyl Exclusion Zone and summarizes the pathways and strategy for handling the radioactive waste related problems in Ukraine and the Chernobyl Exclusion Zone, and in particular, the pathways and strategies stipulated by the National Radioactive Waste Management Program. The brief overview of the radioactive waste issues in the ChEZ presented in this article demonstrates that management of radioactive waste resulting from a ...
To our knowledge, this is the first study to comprehensively estimate the short-term and long-term indirect health impacts of the triple disaster (earthquake, tsunami and nuclear disaster) in Fukushima through the measurement of excess mortality risk. The results of this study showed that postdisaster excess mortality risk was greatest in the first month of the 5-year postdisaster period. This mortality increase may be due to the indirect health effects of the disaster. Previous studies reported increased burdens of chronic diseases and psychological disorders after the disaster in Fukushima, which are consistent with our findings.25 26 In order to mitigate such indirect health effects of disasters, initial public health support, such as facilitating community development, restoring livelihoods, providing psychosocial support to inform people and mobilising community partnership, is important.27-29 This study also suggested the importance of initial public health support, particularly within the ...

MONDAY, Jan. 22, 2018 (HealthDay News) -- A possible link between a cluster of cases in New York City of an extremely rare type of cancer and the 1986 Chernobyl nuclear plant disaster in Ukraine has been found by researchers.. They began their investigation after 10 people in New York City were diagnosed with vitreoretinal lymphoma (VRL) in a four-year span.. VRL affects the eyes and can occur in people with a rare cancer called primary central nervous system lymphoma, a non-Hodgkins lymphoma in the brain or spine. Only about a fourth of those who have this cancer develop VRL.. The cluster of cases prompted the researchers to look closely at various characteristics of the patients, such as their age at diagnosis, racial/ethnic background, family history, where theyve lived and other medical conditions they have.. Thats when they discovered that six of the patients had lived in areas close to the Chernobyl nuclear power plant at the time of the radiation disaster. Four reported living in the ...
This research project is a case study of the Asarco Tacoma smelter and the historical antecendents of widespread soil contamination in the Puget Sound region. From 1890 through 1985, Ruston, a small town near Tacoma, Washington, was home to one of the countrys most polluting smelters, which produced lead, copper, precious metals, arsenic trioxide, and sulfuric acid at various points during its operation. Owned by the American Smelting and Refining Company (Asarco), and primarily a copper smelter, the Tacoma smelter was unique for two reasons: it was able to process ore with high arsenic content; and it was located in an urban area. The environmental consequences of nearly a century of smelting include widespread arsenic, lead and other heavy metal soil contamination, contamination of sediments in Puget Sound, and arsenic slag, a by-product of smelting, dispersed throughout the region. The social consequences include: residents concerns about health, as awareness of potential exposure to toxins ...
