The Radiation Protection Register is a central dose register for the surveillance of occupational radiation exposure. It has the task to control continuously the keeping of the body dose limits of all occupationally exposed persons in Germany and the issuing of radiation passbooks for itinerant workers. The Radiation Protection Register contributes to the international development of the occupational radiation protection as to the state of science and technology and to the harmonization of the occupational radiation protection monitoring in Europe.
As a result of the new Radiation Protection Act (Section 170 StrlSchG) there will be important changes of the data that have to be submitted to the Radiation Protection Register. In particular all individuals subject to registration in the Radiation Protection Register (occupationally exposed individuals and radiation passport holders) need a unique identification number: the Radiation Protection Register Number (SSR Number) starting from 31 December 2018. With the SSR Number, it will be easier and better possible to assign and balance the individual dose values from occupational radiation exposure in the BfS Radiation Protection Register. Moreover it substitutes the previous Radiation Passport Number.. Since 31 December 2018 it is possible to apply for the SSR Number at the BfS. The address of the SSR Portal for the application for the SSR Number is: ...

The research, conducted by the Ministry of Education, Culture, Sports, Science and Technology and the Fukushima plants operator, Tokyo Electric Power Co. (TEPCO), assumed that current radiation levels would be unchanged for a year and that exposed individuals would remain outdoors for eight hours a day.. Of 128 locations within the 20-km zone, researchers projected that annual radiation exposure would exceed 100 millisieverts in only 17 places.. According to the International Commission on Radiological Protection (ICRP), annual radiation exposure exceeding 100 millisieverts poses dangers to health. Annual exposure exceeding 500 millisieverts is associated with a drop in lymphocyte cells in the blood.. The worst-contaminated location had a radiation level that might expose individuals to more than 500 millisieverts in a year. But nearly half of the sample locations had radiation levels below the 20 millisieverts standard used by the central government as a guideline for issuing evacuation ...
Radiation protection technicians protect workers, the general public, and the environment from overexposure to radiation. Many of their activities are highly technical: They measure radiation and radioactivity levels in work areas and in the environment by collecting samples of air, water, soil, plants, and other materials; they record test results and inform the appropriate personnel when tests reveal deviations from acceptable levels; they help power plant workers set up equipment that automatically monitors processes within the plant and records deviations from established radiation limits; and they calibrate and maintain such equipment using hand tools.. Radiation protection technicians work efficiently with people of different technical backgrounds. They instruct operations personnel in making the necessary adjustments to correct problems such as excessive radiation levels, discharges of radionuclide materials above acceptable levels, or improper chemical levels. They also prepare reports ...
Ionizing radiation is used extensively in the field of medicine for either diagnosis or treatment. Hence, an understanding of radiation safety principles and how to apply them in practice is critical for nursing practice. The study was performed to assess nurses knowledge of ionizing radiation and radiation protection during mobile radiodiagnostic examination. A quantitative, descriptive cross-sectional survey was employed for this study to provide better means of investigating and assessing the knowledge, misconceptions and perceptions among 43 nurses assigned to clinical rotations in selected wards of the Korle-Bu Teaching Hospital regarding ionizing radiation and its radiation protection. A purposive sampling method using self-administered questionnaires was used to obtain data in respect of the study. The obtained data was analyzed using SPSS version 16.0. Out of the population of 43 nurses, 25.6% (n=11) were of the view that objects in the X-ray room emitted radiation after an x-ray ...

It is sad and discouraging that NCRP-136 seeks to misrepresent the results of such a large number of sound and thorough studies, and fails to consider objectively the huge discrepancy between the observational data and LNT predictions, which clearly shows that LNT fails the test of reality. Treating many other studies in the same manner, it is our opinion that the NCRP committed a severe violation of the scientific method in defense of the obsolete LNT concept, which has now become a health and societal hazard..

Thermoluminescent dosimeter (TLD) is still in use for many applications such as radiation protection, medical dosimetry, environmental research, and personnel dosimetry, with the overall aim of estimating radiation dose within a given medium or material. The aim of this study was to determine the coefficient of variation (CV) for thermoluminescent (TL) element within the same bar-coded slide and to establish calibration factors (CFs) at dose equivalent of 0.07 mm depth in tissue (Hp [0.07]) and dose equivalent of 10 mm depth in tissue (Hp [10]) for newly purchased TL elements alongside a new RadPro TLD manual reader and annealing oven. Annealed TL elements were taken to a Secondary Standard Dosimetry Laboratory (SSDL) for irradiation using a cesium-137 source at known doses (0.2-2 mGy). A RadPro Cube 400 manual TLD Reader was used to determine corresponding TL signal. The CV between two identical TL element within a bar-coded slide for (Hp [10]) and (Hp [0.07]) was determined and a graph of dose ...
Protecting medical workers and those exposed to naturally occurring radiation, such as air crew and miners, is the next frontier in occupational radiation protection, participants of a conference on the subject in Vienna learned last week.
Creating a scientifically semi-valid super-soldier, part 5: Heart and circulatory system. So youve designed a supercreature for those hard tasks in space. Whether its a miner, a soldier or something else, they are going to be prone to damage to themselves and their suit. Or you might have a police force that has to deal with a lunatic carrying a particle beam. No biggie! you think, they are designed to take some damage! Then after a little while the cancers start popping up all over their bodies and they die horrible deaths, or keel over on the spot from acute radiation poisoning.. Dont let that happen to you! Our scientists have found various ways (I hope) to build in radiation protection regardless of that radiation being from space, the scatter of radiation of a particle beam or just some emergency repairs of your local nuclear reactor.. The solutions would need to be buildable, maintainable and repairable by a biological creature. If you know a way you can build a metallic plastic or ...

Reston, Va. (April 15, 2014) - Image Wisely recently launched its third Image Wisely Radiation Safety Case - CT Brain Perfusion Dose Optimization. This is the latest in a series of free, online and mobile-compatible educational offerings, developed with the assistance of the American College of Radiology, that allow radiologists, imaging technologists and medical physicists to assess their understanding of important radiation safety concepts - including dose monitoring and optimization.. Several years ago, the U.S. Food and Drug Administration investigated a series of unexpected high exposures associated with CT brain perfusion procedures that resulted in skin injuries and hair loss, said Lifeng Yu, PhD, primary author of the new radiation safety case. In an appropriate clinical setting where CT perfusion exams are justified and scanning techniques are correctly used, it is unlikely that the radiation dose would reach the threshold level for skin burns to occur. This case presents strategies ...

Following radiation-release incidents, rigorous evaluation of radiation exposure is fundamental for better understanding of the future health risks as well as for effective radiation protection planning. After the Fukushima incident, because of limited scientific evidence and knowledge with regard to dose reconstruction, we have faced inaccuracy in the government dose estimation model.9 ,12 Hence, to ensure as much accuracy as possible, direct dose measurements using individual radiation dosimeters have been adopted by many local authorities as a major component of their radiation protection policies.14 However, evaluations of proper dosimeter use by individuals is greatly lacking; the errors arising from improper use of the dosimeters are also unknown because of lack of information on users daily behaviour and the conditions under which the dosimeters are worn. Here, the external radiation screening programme provided by Minamisoma City offered a unique and valuable opportunity to address ...

Modern gene perturbation techniques, like RNA interference (RNAi), enable us to study effects of targeted interventions in cells efficiently. In combination with mRNA or protein expression data this allows to gain insights into the behavior of complex biological systems. In this paper, we propose Deterministic Effects Propagation Networks (DEPNs) as a special Bayesian Network approach to reverse engineer signaling networks from a combination of protein expression and perturbation data. DEPNs allow to reconstruct protein networks based on combinatorial intervention effects, which are monitored via changes of the protein expression or activation over one or a few time points. Our implementation of DEPNs allows for latent network nodes (i.e. proteins without measurements) and has a built in mechanism to impute missing data. The robustness of our approach was tested on simulated data. We applied DEPNs to reconstruct the ERBB signaling network in de novo trastuzumab resistant human breast cancer cells, where

A lot of research has been undertaken on the effects of low-level radiation. The findings have failed to support the so-called linear no-threshold (LNT) hypothesis. This theory assumes that the demonstrated relationships between radiation dose and adverse effects at high levels of exposure also applies to low levels and provides the (deliberately conservative) basis of occupational health and other radiation protection standards.. Increasing evidence suggests that there may be a threshold between 100 and 700 mSv below which no harmful effects of radiation occur without effective cellular repair. However, this is not yet accepted by national or international radiation protection bodies as sufficiently well-proven to be taken into official standards. Nevertheless, at low levels of exposure, the bodys natural mechanisms do repair radiation and other damage to cells soon after it occurs, and some adaptive response is stimulated which protects cells and tissues, as with exposure to other external ...
Radionuclide Contamination Treatment for internal radionuclide contamination, also referred to as decorporation, should be started as soon as possible after suspected or known exposure. The approximate upper limit of radionuclide contamination that can reasonably be ignored from a radiation safety point of view is not well defined. These are judgments that will depend on the circumstances of the event and the resources available. The Clinical Decision Guide within the National Council on Radiation Protection and Measurements (NCRP) Report 161 is a decision tool for determining need for treatment for a contaminated person. Purchase of these volumes by major triage centers may be a prudent investment that would assist workers in determining which patients should undergo decorporation.. The goal is to leave the smallest amount of radionuclide possible in the body. Treatment is given to reduce absorption and enhance elimination and excretion. Some of the decorporation agents are not U.S. Food and ...

2014/06/11. Radiation levels in many areas of Fukushima Prefecture designated as zones where it is difficult for residents to return in the foreseeable future remain too high for residents to come back even after decontamination, the Environment Ministry said.. Areas near the Fukushima No. 1 Nuclear Power Plant where the annual radiation levels are over 50 millisieverts and are unlikely to fall below 20 millisieverts within five years after the March 2011 nuclear accident have been designated as zones where it is difficult for residents to return.. The ministry decontaminated six designated areas in the Fukushima Prefecture towns of Namie and Futaba between October last year and January this year as model projects. In the decontamination work, the surface of soil was stripped away, soil was cleaned with high-pressure water and weeds were removed.. As a result, the average airborne radiation levels in residential areas, on farmland and roads, which had stood at 7.65 to 19.12 microsieverts per ...
The coastal belt of Karunagappally, Kerala, India, is known for high background radiation (HBR) from thorium-containing monazite sand. In coastal panchayats, median outdoor radiation levels are more than 4 mGy y-1 and, in certain locations on the coast, it is as high as 70 mGy y-1. Although HBR has been repeatedly shown to increase the frequency of chromosome aberrations in the circulating lymphocytes of exposed persons, its carcinogenic effect is still unproven. A cohort of all 385,103 residents in Karunagappally was established in the 1990s to evaluate health effects of HBR. Based on radiation level measurements, a radiation subcohort consisting of 173,067 residents was chosen. Cancer incidence in this subcohort aged 30-84 y (N = 69,958) was analyzed. Cumulative radiation dose for each individual was estimated based on outdoor and indoor dosimetry of each household, taking into account sex- and age-specific house occupancy factors. Following 69,958 residents for 10.5 years on average, 736,586 ...

Spacecraft, both manned and unmanned, must cope with the high radiation environment of outerspace. Radiation emitted by the Sun and other galactic sources, and trapped in radiation belts is more dangerous and hundreds of times more intense than radiation sources such as medical X-rays or normal cosmic radiation usually experienced on Earth.[24] When the intensely ionizing particles found in space strike human tissue, it can result in cell damage and may eventually lead to cancer.. The usual method for radiation protection is material shielding by spacecraft and equipment structures (usually aluminium), possibly augmented by polyethylene in human spaceflight where the main concern is high energy protons and cosmic ray ions. On unmanned spacecraft in high electron dose environments such as Jupiter missions, or medium Earth orbit (MEO), additional shielding with materials of a high atomic number can be effective. On long duration manned missions, advantage can be taken of the good shielding ...

This Presidential Report from the National Council on Radiation Protection and Measurements (NCRP) has been prepared at the request of the Food and Drug Administration (FDA). FDA has the responsibility for regulating the manufacture of electronic products that emit ionizing and nonionizing radiation and is working with the Transportation Security Administration (TSA), which has the responsibility of providing security measures for transportation activities. The FDA asked the NCRP for advice on radiation protection issues concerning exposure to ionizing radiation from radiation-producing devices used for non-medical security purposes. These devices, particularly x-ray scanning systems, are being evaluated by various agencies (e.g., U.S. Customs Service and TSA) for use in security screening of humans. The use of such scanning devices involves a broad societal decision that needs to be made through appropriate procedures by the authorities utilizing the x-ray producing electronic products (and ...

Clean-up efforts at Japans Fukushima nuclear plant, destroyed by a massive earthquake and tsunami in 2011, have significantly reduced radiation levels but untreated forested areas remain a problem, scientists said Thursday.
Medical imaging technologies and techniques continue to evolve rapidly and while providing unprecedented visibility into the body, their use mean exposure of patients to ionizing radiation. This is an area requiring attention in Canada.. To address the need for a national strategy and action plan relating to radiation safety for medical imaging care in Canada, a coalition of key stakeholders is being formed, called Canada Safe Imaging. Canada Safe Imaging will be formally launched in the months ahead with invitations to participate to include agencies, professional associations, universities, colleges, national research institutions and hospitals.. One impetus for this new Canadian initiative was to align with the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO) initiative, supported by 77 countries and 16 organizations, titled the Bonn Call-for-Action, which outlines 10 major strategies for promoting radiation protection.. The delivery of health care is a ...
BACKGROUND AND PURPOSE: Advancements in medical device and imaging technology as well as accruing clinical evidence have accelerated the growth of the endovascular treatment of cerebrovascular diseases. However, the augmented role of these procedures raises concerns about the radiation dose to patients and operators. We evaluated patient doses from an x-ray imaging platform with radiation dose-reduction technology, which combined image noise reduction, motion correction, and contrast-dependent temporal averaging with optimized x-ray exposure settings. MATERIALS AND METHODS: In this single-center, retrospective study, cumulative dose-area product inclusive of fluoroscopy, angiography, and 3D acquisitions for all neurovascular procedures performed during a 2-year period on the dose-reduction platform were compared with a reference platform. Key study features were the following: The neurointerventional radiologist could select the targeted dose reduction for each patient with the dose-reduction platform,
by admin , Mar 15, 2013. Radiation dose received by patients during invasive cardiology procedures has the potential to cause skin damage and is assumed to include a small cancer risk. To help ensure patient safety, it is desirable to minimize patient radiation dose to patients undergoing these procedures. An inherent benefit of reduced patient dose is reduced dose to physician operators and staff. Previous studies have tested patient radiation dose-reduction initiatives for radiofrequency ablation and invasive coronary artery procedures. Few studies, however, have explored the effects of using sustained patient radiation dose-reduction initiatives in larger, diverse invasive cardiovascular settings. A Progressive Movement on Patient Radiation In an issue of JACC: Cardiovascular Interventions, Kenneth A. Fetterly, PhD, and colleagues had a single-center study published that investigated the effects of sustained practice and x-ray system technical changes on radiation doses administered to adult ...

Russias nuclear agency on Saturday said an explosion during missile testing in the Arctic left five workers dead and involved radioactive isotopes after a nearby city recorded a spike in radiation levels. Rosatom said the force of the explosion on Thursday blew several of its staff from a testing platform into the sea. Russias military did not initially say that the accident involved nuclear equipment, but stressed that radiation levels were normal afterwards. Officials in the nearby city of Severodvinsk reported that radiation levels briefly increased after the accident. The incident occurred in the far northern Arkhangelsk region during testing of a liquid

No one is going to convince the public that the increasing radiation will have a general effect on our health that can be easily traced back to the source. Even before we get cancer from radiation we have a general down-spiraling of body functions because of all the oxidative stress. In my book, New Paradigms in Diabetes, I write extensively about the direct relationship between magnesium deficiency and the onset of diabetes.. Pancreatic beta cells are sensitive to reactive oxygen species (ROS) [8] attack when they are exposed to oxidative stress,[9] because of the relatively low expression of antioxidant enzymes such as catalase and glutathione peroxidase.[10] Diabetes is typically accompanied by increased production of free radicals and/or impaired antioxidant defense capabilities, indicating a central contribution of reactive oxygen species. It is also a fact that ROS is one of the major factors that induce oxidative modification of DNA and gene mutation.[11]. The Chernobyl incident was a ...

When it comes to children and teenagers, there have been nearly a dozen countries around the world issuing warnings about the health risks to children and teenagers using cell phones. France is in the process of making it illegal to market cell phones to children under the age of 12. The Unite Kingdom, Germany, Belgium, Israel, Russia, and India have advised that children should have their use of cell phones limited or used only for emergencies.. Finlands Radiation and Nuclear Safety Authority are saying that radiation from cell phones could be a health risk, but research as to the effects of prolonged use is still unclear. In Russia, it has been recommended that children under the age of 18 should not use cell phones at all.. And further, if there were no concerns, why was there a Senate ...

However, improperly handled radioactive sources can lead to excessive exposure to radiation, which in turn may have negative effects on your staffs health (radiation burns, increased risk of cancer, etc) and have legal implications for your company (worker liability claims, license revocation, penalty fees, etc). The use of radioactive materials is therefore strictly regulated in Canada by the Canadian Nuclear Safety Commission (CNSC). In most cases, you must obtain a license from the CNSC before radioactive materials can even be purchased.. The CNSC requires all license applicants to demonstrate that radioactive materials or nuclear technologies in their possession meet federal regulatory requirements for health, safety, security and environmental protection. The process of obtaining a license from the CNSC is labour intensive. In addition to preparing the actual license application, you will have to develop a Radiation Protection Program that answers the specific needs of your workplace. If ...

Preliminary research indicates that passengers and crews are being exposed to more radiation than previously thought, especially during significant solar events. Mertens analyzed data from a strong solar storm around Halloween 2003 and found that passengers on polar flights - for example from Chicago to Beijing - were exposed to radiation higher than the limit recommended by the International Commission on Radiological Protection. In addition, not including new features in the model such as magnetic storm effects on Earths magnetic field underestimated the exposure during that storm by a factor of four ...

Final Environmental Impact Statement, Environmental Radiation Protection Requirements for Normal Operations of Activities in the Uranium Fuel Cycle, p. 18.). Before the transfer of environmental radiation responsibilities from the AEC to the EPA, and until the EPA issued the new rule in 1977, the annual radiation dose limit for a member of the general public from nuclear fuel cycle operations was 5 mSv-20 times higher than the EPAs limit.. The AEC had conservatively assigned a limit of 1/10th of the 50 mSv/year applied to occupational radiation workers, which it had, in turn, conservatively chosen to provide a high level of worker protection from the potential negative health effects of atomic radiation.. The AECs occupational limit of 50 mSv was less than 1/10th of the previously applied tolerance dose of 2 mSv/day, which worked out to an annual limit of approximately 700 mSv/year. That daily limit recognized the observed effect that damage resulting from radiation doses was routinely ...
There is a wide variation of risk estimates for second cancer in the literature. Lifetime breast cancer induction risk for a breast exposed to 1 Gy is approximately 5% if irradiated at the age of , 35, , 3% at the age of 35-45, and much less at an older age [10]. For a phantom case study [21] the incremental risk of secondary cancer was calculated for the tangential whole breast technique with wedge compensators based on National Council on Radiation Protection and Measurements (NCRP) report 116 [20] as 0.34% which is likely to be undetectable compared to the observed frequency of contralateral breast cancer of about 7% at 10 years and 10% at 15 years [28, 29]. The causes of contralateral breast cancer amongst breast cancer patients given radiotherapy are less obvious. A large study by Kirova et al. did not show an increased risk of contralateral breast cancer for those receiving radiotherapy [30]. Obedian reported no significant difference in the occurrence of contralateral breast cancer at 15 ...

Current safety standards adopted by federal agencies like OSHA were developed by industry groups and are obsolete. EPA senior scientist and radiofrequency (RF) radiation expert, Norbert Hankin, wrote, Both the NCRP (National Council on Radiation Protection) and ANSI/IEEE standards are thermally based and do not apply to chronic non-thermal exposure situations. In other words, if it doesnt cook tissue, it is assumed to be safe. Research indicates however that low-power exposure (WiFi is low power) has been shown to have numerous biological effects which can lead to serious health consequences, including neurological, cardiological and hormonal disorders, breakdown of the blood-brain barrier, DNA damage, cancers, diabetes and asthma. Children, to whom public libraries cater, have brains and nervous systems that are still developing; they are particularly vulnerable ...

AIM: To quantify cumulative effective dose of intensive care unit (ICU) patients attributable to diagnostic imaging. METHODS: This was a prospective, interdisciplinary study conducted in the ICU of a large tertiary referral and level 1 trauma center. Demographic and clinical data including age, gender, date of ICU admission, primary reason for ICU admission, APACHE II score, length of stay, number of days intubated, date of death or discharge, and re-admission data was collected on all patients admitted over a 1-year period. The overall radiation exposure was quantified by the cumulative effective radiation dose (CED) in millisieverts (mSv) and calculated using reference effective doses published by the United Kingdom National Radiation Protection Board. Pediatric patients were selected for subgroup-analysis. RESULTS: A total of 2737 studies were performed in 421 patients. The total CED was 1704 mSv with a median CED of 1.5 mSv (IQR 0.04-6.6 mSv). Total CED in pediatric patients was 74.6 mSv ...
