Interacting populations affecting proliferation of leukemic cells in culture. (1/32)

Peripheral blood cells from three patients with acute leukemic have been studied using a suspension culture method previously described.1 Cytogenetic studies in two of the patients permitted the identification of the proliferating cells in the cultures as being derived from a leukemic population. Cell separation studies using velocity sedimentation supported the concept that growth of the leukemic cells in culture is dependent on an interaction between two populations of leukemic cells.  (+info)

Permeability of squid axon membrane to various ions. (3/32)

The permeability of the squid axon membrane was determined by the use of radioisotopes of Na, K, Ca, Cs, and Br. Effluxes of these isotopes were measured mainly by the method of intracellular injection. Measurements of influxes were carried out under continuous intracellular perfusion with an isotonic solution of potassium sulfate. The Na permeability of the resting (excitable) axonal membrane was found to be roughly equal to the K permeability. The permeability to anion was far smaller than that to cations. It is emphasized that the axonal membrane has properties of a cation exchanger. The physicochemical nature of the "two stable states" of the excitable membrane is discussed on the basis of ion exchange isotherms.  (+info)

EFFECT OF CHLOROTHIAZIDE ON CESIUM-137 EXCRETION IN HUMAN SUBJECTS. (4/32)

The therapeutic value of the diuretic, chlorothiazide (Diuril), in reducing the body burden of cesium-137 in human subjects was investigated. Two subjects were given chlorothiazide, 2 g./day, following a single oral intake of cesium-137. The urinary excretion and the per cent retention of cesium-137 were compared with similar data obtained from two control subjects. Although chlorothiazide produced a marked potassium diuresis, it had no significant effect in reducing the body burden of cesium.Analysis was made of the rate of turnover of cesium and potassium in the two control subjects, who were followed up for 320 days. The biological half-lives, T(b), of K were 42 and 41 days. In both subjects a small fraction of the cesium-137 was rapidly excreted. The remainder (88% and 83% in the two cases) was excreted at a slower constant rate. The concentrations further decreased to 44% and 41.5% in 90 and 155 days, respectively.  (+info)

Cs + ADC in rat brain decreases markedly at death. (5/32)

Spectroscopic resolution of intracellular and extracellular compartments can be used to probe the kinetic environment of those spaces and the compartment-specific changes that occur following injury. This is important for understanding the biophysical mechanisms that underlie the remarkable diffusion-weighted MRI contrast of injured central nervous system (CNS) tissue. Cesium-133 is a physiologic analog of potassium that is actively taken up by cells and resides primarily in the intracellular space. The (133)Cs(+) signal can, thus, be exploited to probe the kinetic environment of the intracellular space. Two principal (133)Cs(+) resonances were observed at 11.74 T. These resonances arise separately from (133)Cs(+) in brain and temporalis muscle. The apparent diffusion coefficient (ADC) of Cs(+) in brain decreased from 1.0 +/- 0.2 microm(2)/ms in healthy tissue to 0.24 +/- 0.04 microm(2)/ms following global ischemia (average ADC +/- average uncertainty), while there was no significant change in the ADC of Cs(+) in temporalis muscle after injury. This finding underscores the tissue-specific nature of the decrease in ADC that accompanies brain injury. Further, as the Cs(+) ADC should reflect water ADC in the intracellular space, these results strongly support the hypothesis that the decrease in water ADC associated with CNS injury arises largely from kinetic changes taking place in the intracellular space.  (+info)

Direct enzymatic repair of deoxyribonucleic acid single-strand breaks in dormant spores. (8/32)

With the alkaline sucrose gradient centrifugation method, it was found that dormant spores of Clostridium botulinum subjected to 300 krads of gamma radiation showed a distinct decrease in deoxyribonucleic acid (DNA) fragment size, indicating induction of single-strand breaks (SSB). A two- to threefold difference in radiation resistance of spores of two strains of C. botulinum, 33A (37% survival dose [D(37)] = 110 krads) and 51B (D(37) = 47 krads), was accompanied by relatively larger DNA fragments (molecular weight 7.9 x 10(7)) obtained during extraction from the radiation-resistant strain 33A and smaller DNA fragments (molecular weight 1.8 x 10(7)) obtained under identical conditions from radiation-sensitive strain 51B. The apparent number of DNA SSB produced by 300 krads in strains 33A and 51B was 0.37 and 3.50, respectively, per 10(8) daltons of DNA. Addition of 0.02 M ethylenediaminetetraacetic acid (EDTA) to spore suspensions during irradiation doubled the apparent number of SSB in strain 33A but had no effect on strain 51B. In vivo, 0.02 M EDTA present during irradiation to 100 to 300 krads decreased survival of spores of 33A by about 30% but had little or no effect on 51B. Survival of 33A was also reduced by about 45% when the spores were irradiated while frozen in dry ice (-75 C) and, after irradiation, immediately exposed to 0.03 M EDTA for 1 h to inhibit repair in the dormant spores. These results suggest that the highly radiation-resistant strain 33A may be able to accomplish repair of SSB during irradiation or after irradiation under nonphysiological conditions, i.e., in the dormant state. This repair can be inhibited by EDTA. Sedimentation patterns show that DNA from spores of both strains 33A and 51B did not show any postirradiation repair during the first 6 h of germination, as opposed to Bacillus subtilis spores, which exhibit repair immediately after germination. These observations suggest the existence of direct repair in physiological dormant spores of strain 33A in the cryptobiotic resting state in the absence of germination. The repair seems to be similar to that of polynucleotide ligase activity shown to be operative in some vegetative cells. Apparently radiation-sensitive strains such as 51B and B. subtilis are generally poor in DNA repair enzyme activity under conditions of spore dormancy, which may account for the approximately threefold difference in radiation sensitivity or DNA fragility of different strains, or both.  (+info)

In Chinese medical form, Chinese medicine is widely used in the treatment of various kidney diseases. In addition, many natural treatments have been developed based on Chinese medicine. And the therapy of purifying toxins from the blood takes on the best effects, helping patients reduce high levels of creatinine. From many years of clinical experience, if waste products and toxins are eliminated from the body, firstly, patients can often act better than those who do not eliminate waste products, since toxins in the blood not only cause additional damage to kidney and tissue cells , and also affect the effectiveness of drugs for the treatment of the kidneys. Because the toxins deposited in the blood not only cause additional damage to the kidney function, but also affect the effectiveness of treatment of kidney drugs. Therefore, this treatment mainly uses medicinal herbs that help patients to isolate products from waste and toxic substances. When using herbal medicines, various natural products ...

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 ...

Patients with brain metastases from lung cancer have poor prognoses and short survival time, and they are often excluded from clinical trials. Whole-cranial irradiation is considered to be the standard treatment, but its efficacy is not satisfactory. The purpose of this phase II clinical trial was to evaluate the preliminary efficacy and safety of the treatment of whole-brain irradiation plus three-dimensional conformal boost combined with concurrent topotecan for the patients with brain metastases from lung cancer. Patients with brain metastasis from lung cancer received concurrent chemotherapy and radiotherapy: conventional fractionated whole-brain irradiation, 2 fields/time, 1 fraction/day, 2 Gy/fraction, 5 times/week, and DT 40 Gy/20 fractions; for the patients with ≤ 3 lesions with diameter ≥ 2 cm, a three-dimensional (3-D) conformal localised boost was given to increase the dosage to 56-60 Gy; and during radiotherapy, concurrent chemotherapy with topotecan was given (the chemoradiotherapy
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.

TY - JOUR. T1 - Cation effects on cell shape.. AU - Sheetz, Michael. PY - 1977/12/1. Y1 - 1977/12/1. N2 - We have found that human erythrocyte ghosts in 10 mM HEPES (pH 7.0) at 0 degrees C would crenate when 20-50 mM of Na+ or K+, 0.2-0.5 mM OF Ca++, Ba++, Sr++, or Mg++, or 10 muM of La+++ was added. The shape change after cation addition was faster than fixation by 1% glutaraldehyde at 4 degrees C and was readily reversible upon dilution of the cation. After incubation of ghosts in 10 mM HEPES (pH 7.0) at 37 degrees for 10-20 min there was a significant inhibition of subsequent crenation by cations. In a process that is believed to occur by a similar mechanism, whole red blood cells were observed to cup (invaginate) when 20 mM of a divalent or 0.1 mM of a trivalent cation was added. After neuraminidase treatment to remove the sialic acid charge groups, these same shape changes were observed in ghosts and whole cells. Another type of cation-induced crenation was found to follow upon the addition ...

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.

This is an article about the facts on nuclear war and what would happen and how you would survive and what youd need to do if you did survive a nuclear attack. A very sobering look into the atomic fury and what it would take for this disaster to happen and what you would need to do in order to live through it.
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. ...
Haploinsufficiency of Meis1 is a potential model system for simulating RLS in mice. Here, we show that this Meis1 deficit causes a sex- and context-dependent RLS-related phenotype at middle age, impaired sensorimotor gating ability that was refractory to the D2/3R agonist pramipexole as well as increased social memory. These behavioral abnormalities occurred without differences in thermal sensitivity, plasma iron concentrations or dopaminergic neuron number in the SNpc/VTA. Thus, although Meis1 haploinsufficiency causes the RLS-related phenotype of motor restlessness in mice, the detailed nature of these effects is complex. Furthermore, it is characteristically distinct from other genetic RLS models (e.g. Btbd9 knock-out), highlighting the heterogeneous nature of the effects of these different risk genotypes in this disease.. Motor restlessness in these Meis1-haploinsufficient mice was detected previously in young adult male and female mice (Spieler et al., 2014). RLS is, however, more prevalent ...
One of the most infamous symbols of life-threatening pollution is the Chernobyl reactor, which suffered a meltdown in April 1986. 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.

TJ Olsen last week underwent the first of three open-heart surgeries scheduled before his third birthday. The first procedure is the most risky and invasive, but the doctor who performed the surgery said early signs are positive. Olsen, in his second year with the Panthers, will be spending several nights a week at the Charlotte hospital, where TJ will remain for about 40 days. He said hes grateful for the support of the Panthers, including owner Jerry Richardson, who chartered a plane and accompanied the Olsens to Boston in May for consultations with pediatric heart specialists. TJs middle name is Jerry in honor of the Panthers owner. Meanwhile, Olsen is the Panthers leading receiver with 22 catches and ranks among the top 10 tight ends in the league in receiving with 293 yards and a touchdown. NOTES: Ron Rivera tiptoed around the issue during the bye week, but will have to decide this week who starts at middle linebacker. Pro Bowler Jon Beason, coming off Achilles surgery a year ago, ...

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 ...

AU - Hansen, Heinke C.. AU - Schild, Steven E.. AU - Rades, Dirk. PY - 2018/6/1. Y1 - 2018/6/1. N2 - Background/Aim: Patients with cerebral metastases from gynecological cancer who receive whole-brain irradiation (WBI) alone require personalized therapy. This study contributes to personalized care by creating an instrument to predict 6-month survival probability. Patients and Methods: In 49 patients, six pre-treatment variables, namely age, Eastern Cooperative Oncology Group performance score (ECOG-PS), primary tumor type, number of cerebral metastases, metastasis outside the brain, and interval between diagnosis of gynecological cancer and WBI, were analyzed for survival. Results: Of the six pre-treatment variables, ECOG-PS was significantly associated with survival (p=0.014) and metastasis outside the brain ...
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 ...
Other beneficial effects mediated by RAAS inhibitors in diabetic nephropathy include: ACE inhibitors increase the permeability selectivity of the filtering membrane, thereby diminishing exposure of the mesangium to proteinaceous factors that may stimulate mesangial cell proliferation and matrix production, two processes that contribute to expansion of the mesangium in diabetic nephropathy. Because Ang II is a growth factor, reductions in the intrarenal levels of AngII may further attenuate mesangial cell growth and matrix production.. This is why they are the drugs of choice for hypertensive patients with diabetes and are even being used in patients with diabetic nephropathy but are not hypertensive.. 2.

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. In 1998, Bray, a PNNL retiree and internationally recognized expert in medical isotopes and Don Segna, a retired engineer, formerly with the ...

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 Elephants Foot could be the most dangerous piece of waste in the world," (Chernobyls Hot Mess, "the Elephants Foot," is Still Lethal, Nautilus, Science Connect, Dec. 4, 2013).

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 ...
A reader asks: "As a man at middle age, I am concerned about my eyesight. How can I preserve my eyesight and prevent the progression of vision loss, or is it unavoidable? I am now wearing over-the-counter reading glasses. What is it about carrots, or is that an urban myth?". Sure, aging takes its toll on our eyesight. As time rolls on, the surface of the cornea, the clear covering, flattens and lets less light into the eye. The macula, part of the retina, becomes thinner. Free radicals generated by environmental toxins and our normal body functions also cause many changes. Years of poor eating habits also contribute to visual problems as we age. However, the good news is, rarely is it too late to make a difference. The right changes in lifestyle and diet always can make an improvement. And so it is true also with age-related macular degeneration (AMD), cataracts and glaucoma. These conditions are the most common causes of loss of vision in people over 40. AMD occurs when cells in the macula ...

As I gently lift my head from my snuggly slumber in my little dog bed, I hear the Dad going out the door, so it must be time for me to wake somebody. Who will it be today? The Dad is already on his way to work, the big tall boy could sleep through a nuclear attack, the Mom is a little bit on the slow side, so I think Ill wake the girl since she usually gets up quickly without too much grumbling.

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 ...
Bone strength and peak bone mass are preliminary determined by genetic factors. Life style, especially exercise, is also considered to have an important effect on bone strength. Bone has the ability to strengthen itself according to Wolffs Law. When bone is subjected to strains and/or strain rates higher than the usual, it responds by remodeling, strengthening its architecture. The ability is greatest in young individuals and decreases with age. In the elderly this ability is largely non-existent and bone mass is lost. Whether this loss leads to osteoporosis is largely a function of the peak bone mass achieved before the decline. 11% of males and 44 % of females over 50 suffer from osteoporosis in later life. To what extent vigorous exercising beginning at a young age can increase bone strength is not known.. The purpose of the proposed research is to quantify the effect of life style on bone strength and general health parameters by comparing two male populations, one sedentary and the other ...

Nuclear radiation does contain cancer-causing chemical isotopes, including iodine-131, cesium-137, strontium-90 and plutonium-239. Though plutonium remains in the environment for several thousand years, multiple studies have shown that significant radiation exposure - some reports say as much as 1,000 millisieverts - is required to increase the cancer incidence by even 5%. For the sake of comparison, a chest X-ray exposes a patient to 0.1 millisievert of radiation.. Read entire article here ...
Larvae of the Caribbean fruit fly, Anastrepha suspensa (Loew), were irradiated at hatching with 0, 5, 10, 20, 50, 75, 100 and 150 Gy doses from a Cesium-137 source and dissected for measurements of the supraesophageal ganglion (brain) and proventriculus (B/Prv) as mature third instars. Cross-sectional area of a plane through the brain and proventriculus, and simple dorsal width measurements of the two organs were evaluated as indicators of radiation exposure. Brain area, brain width, and brain/proventriculus (B/Prv) ratios were significantly different from controls in insects treated with a dose {ge}20 Gy. Detailed dissections of hatching larvae exposed to 50 Gy revealed reductions in brain growth, small and misshapen compound eye and leg imaginal disks, and a ventral nerve cord that was elongated and sinuous. Larvae irradiated on the 1st d of each of the three instars had smaller brains, with the percentage of reduction in brain size being greater the younger the larvae were at the time of ...
The thesis also highlights regional differences between gray and white matter in microglia priming in the aging mouse and human brain. Surprisingly, microglia priming in the white matter already begins at middle age in humans. The increased and persistent white matter microglia priming draws attention to the role of white matter changes particularly in axons in brain aging and explores the possible use of white matter priming as a predictive factor to envisage the progression of cognitive aging and onset of neurodegeneration. It is well known that other clinical parameters such as Aβ plaque pathology, tau accumulation do not linearly correlate to cognitive impairments in the elderly. Microglia-mediated neuroinflammation in the white matter together with functional assessment of white matter function using non-invasive approaches such as Diffusion Tensor Imaging (DTI) and pathological markers of axonal dystrophy could yield powerful predictive tools for the assessment of cognitive impairment and ...

Avidocin-CDs are also an example of a precision antibiotic that does not disrupt the gut microbiota. Kirk et al. [8] demonstrated that the Avidocin-CD class of bactericides specifically kills C. difficile by targeting SlpA, the primary component of the C. difficile S-layer. Various forms of Avidocin-CDs can be designed that kill particular isolates of C. difficile based on the S-layer type [8]. Although S-layer-null mutants that are resistant to this bactericide have been identified in vitro, they are avirulent, which demonstrates the importance of the S-layer in C. difficile sporulation and toxin production [8]. By showing that resistance to Avidocin-CDs forces C. difficile to lose virulence, this work provides an elegant example of the advantages to designing bactericides that target virulence factors.. Successful precision therapeutics may also target a variety of other virulence pathways, such as toxin production. Small molecules virstatin and toxtazin B are antivirulence inhibitors 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 ...
The destructive nature of nuclear meltdowns was put on full display earlier this year after an 8.9 magnitude earthquake the stuck Japan on March 11. Nuclear and medical experts predict that the large quantities of radiation unleashed during the accident at Fukushima will result in untold harm to human health for generations.[27] Reactor 3 at Fukushima, which was breached during the earthquake, contained plutonium - one of the most deadly nuclear contaminants known to man. If even a tiny grain of plutonium is breathed in, it will cause so much damage to body tissues that cancer is a near certainty.[28] Japans Nuclear and Industrial Safety Agency reported in August that the amount of cesium-137 that has leaked from the plant so far is 168 times greater than what was released during the dropping of the atomic bomb on Hiroshima in 1945.[29] The amount of Iodine -131, a radioactive isotope that has very damaging effects on the thyroid gland, was also found to be 2.5 times greater than what was ...

Assume every line of defense against nuclear terrorism is breached: the efforts to lock up nuclear material abroad, to spy out hidden weapons programs, to deter rogue states and capture terrorists, to detect smuggled bombs at the border or downtown every preventive measure discussed in the previous five installments of this series. Assume someone, somehow, gets all the way through. It only has to happen once. Assume that this someone puts together a crude atomic bomb, of the Little Boy type dropped on Hiroshima in 1945, a heavy and awkward device but one still small enough to fit into a medium-size truck. Assume that of all the potential targets in the world, from Los Angeles to Moscow, the spot where this someone parks the bomb is on Pennsylvania Avenue, halfway between the White House and the U.S. Capitol.
