    Full Text Available The 11-M Madrid commuter train bombings of 2004 constituted the second biggest terrorist attack to occur in Europe after Lockerbie, while the subsequent investigation became the most complex and wide-ranging forensic case in Spain. Standard short tandem repeat (STR profiling of 600 exhibits left certain key incriminatory samples unmatched to any of the apprehended suspects. A judicial order to perform analyses of unmatched samples to differentiate European and North African ancestry became a critical part of the investigation and was instigated to help refine the search for further suspects. Although mitochondrial DNA (mtDNA and Y-chromosome markers routinely demonstrate informative geographic differentiation, the populations compared in this analysis were known to show a proportion of shared mtDNA and Y haplotypes as a result of recent gene-flow across the western Mediterranean, while any two loci can be unrepresentative of the ancestry of an individual as a whole. We based our principal analysis on a validated 34plex autosomal ancestry-informative-marker single nucleotide polymorphism (AIM-SNP assay to make an assignment of ancestry for DNA from seven unmatched case samples including a handprint from a bag containing undetonated explosives together with personal items recovered from various locations in Madrid associated with the suspects. To assess marker informativeness before genotyping, we predicted the probable classification success for the 34plex assay with standard error estimators for a naïve Bayesian classifier using Moroccan and Spanish training sets (each n = 48. Once misclassification error was found to be sufficiently low, genotyping yielded seven near-complete profiles (33 of 34 AIM-SNPs that in four cases gave probabilities providing a clear assignment of ancestry. One of the suspects predicted to be North African by AIM-SNP analysis of DNA from a toothbrush was identified late in the investigation as Algerian in origin. The

    The capital of Spain since 1562, Madrid is located on the geographic center of the Iberian Peninsula. Because of its central location and high altitude, the climate of Madrid is characterized by warm dry summers and cool winters. Madrid is a city of great monuments. Among its highlights are the medieval center dating back to the Habsburg Empire and the Prado Museum. "El Madrid de los Austrias" is how Spaniards call the part of

  4. La publicidad de duelo como agente público de protesta social: análisis del atentado del 11M en Madrid en 2004

    Full Text Available La publicidad de duelo se ha identificado tras los atentados del 11S y 11M. El dolor y el sufrimiento son los elementos clave de ésta como reflejo y espejo de una protesta social. Este estudio se centra en el campo de la comunicación y, de forma más específica, en la publicidad. 11 de marzo de 2004 es una fecha que todo español recuerda como el mayor atentado terrorista perpetrado en Madrid a manos de Al Qaeda. En los días posteriores a la barbarie, hubo numerosas manifestaciones de repulsa ante el hecho y de condolencia hacia las víctimas y familiares. Los anunciantes, como un sujeto más de la sociedad, quisieron expresar su dolor y solidaridad a través de los espacios publicitarios en prensa. Aun cuando a priori, la publicidad parezca tener un rechazo a todo lo que suponga dolor, es un sentimiento universal, inevitable y común a todas las personas. En especial, cuando suceden agresiones contra la humanidad como los del 11S y 11M, cuyo daño puede afectar y provocar dolor a todos y cada uno de los miembros de un grupo, ya sean víctimas activas o pasivas del mismo acto brutal. De esta forma, se analizaron los anuncios aparecidos en prensa en los días posteriores al atentado en España y se clasificaron en una tipología según sus mensajes, además de identificarlos bajo una misma modalidad de publicidad denominada de duelo, como sinónimo de un agente público de protesta social que reúne las características propias de la naturaleza publicitaria.

  5. Facing Catastrophe - Risk and Response: The 9-11 and 11-M Commissions' Blind Sides

    Atran, Scott

    2005-01-01

    Background thinking for the upcoming Madrid terrorism summit stems partly from the 9/11 Commission and Spain's Comisión 11-M. Their presentations fall short on pinpointing the sources of attacks that carry the most risk and how best to respond. Terrorist attacks over the last decades follow a power-law distribution, which anticipates future terrorist events with ever broader effects. Intelligence estimates based on models keyed to frequency and recency of past occurrences make us less secure ...

    2007-01-01

    Advancements in technology coupled with the perception of diminished public tolerance for casualties have increased the prominence and popularity of aerial bombing as a coercive tool, particularly for the United States. Despite interest from policy makers and support from the public, there has been little scholarly assessment of these coercive episodes. How successful are air campaigns, and what are the prospects for the future? In this article, I focus on the factors that cause bombing campa...

  7. Bomb parameters

    The reconstruction of neutron and gamma-ray doses at Hiroshima and Nagasaki begins with a determination of the parameters describing the explosion. The calculations of the air transported radiation fields and survivor doses from the Hiroshima and Nagasaki bombs require knowledge of a variety of parameters related to the explosions. These various parameters include the heading of the bomber when the bomb was released, the epicenters of the explosions, the bomb yields, and the tilt of the bombs at time of explosion. The epicenter of a bomb is the explosion point in air that is specified in terms of a burst height and a hypocenter (or the point on the ground directly below the epicenter of the explosion). The current reassessment refines the energy yield and burst height for the Hiroshima bomb, as well as the locations of the Hiroshima and Nagasaki hypocenters on the modern city maps used in the analysis of the activation data for neutrons and TLD data for gamma rays.

  11. The neutron bomb

    The 'weapon with increased radiation', as the neutron bomb is officially called, has become the subject of fervent discussions. As a substitute for nuclear bombs it is said to reduce the damage to the non-combatant population when tactically deployed, having a greatly reduced radius of action - that at least is what the military say, who are in favour of it. The article describes the radiation effect of the atomic bomb from the examples of Hiroshima and Nagasaki. The report on the military concept and development of the neutron bomb is followed by a description of how might be constructed. (orig.)

  14. Yields of the bombs

    The calculations reported in later chapters require knowing how many fissions took place in each bomb. The literature gives the average energy released per fission; so an equivalent quantity is the energy released by each bomb. The energy released is called the 'yield'. The yield is given in kilotons. Here 'kiloton' is used as a unit of energy, not of mass. It is defined as 1012 calories or approximately the energy released in the explosion of one kiloton (kt) of TNT. The bomb exploded over Hiroshima was a gun-type device using enriched uranium and was the only detonation ever made of this type of device. The bomb exploded over Nagasaki was an implosion device using plutonium and was the same type as the bombs tested at Trinity in New Mexico and at the Able and Baker tests of Operation Crossroads at Bikini Atoll in 1946. These test data were the primary source of information used in determining the yield of the Nagasaki bomb. The yield of the Hiroshima bomb was determined by comparison with effects observed in the two cities and by some of the other methods listed below. Because of the importance of the yields to the reassessment program, they have been studied many times

  15. Korean atomic bomb victims.

    Sasamoto, Yukuo

    2009-01-01

    After colonizing Korea, Japan invaded China, and subsequently initiated the Pacific War against the United States, Britain, and their allies. Towards the end of the war, U.S. warplanes dropped atomic bombs on Hiroshima and Nagasaki, which resulted in a large number of Koreans who lived in Hiroshima and Nagasaki suffering from the effects of the bombs. The objective of this paper is to examine the history of Korea atomic bomb victims who were caught in between the U.S., Japan, the Republic of Korea (South Korea) and the Democratic People's Republic of Korea (North Korea). PMID:20521424

  16. Atomic bomb cataracts

    Eye disturbance caused by atomic bomb radiation can be divided into three groups: direct injury immediately after exposure, eye lesions associated with radiation syndrome, and delayed disturbance. The crystalline lens of the eye is the most radiosensitive. Atomic bomb cataract has been investigated in a number of studies. The first section of this chapter discusses radiation cataract in terms of the incidence and characteristics. The second section deals with atomic bomb cataract, which can be diagnosed based on the four criteria: (1) opacity of the crystalline lens, (2) a history of proximal exposure, (3) lack of eye disease complicating cataract, and (4) non-exposure to radiation other than atomic bombing. The prevalence of cataract and severity of opacity are found to correlate with exposure doses and age at the time of exposure. Furthermore, it is found to correlate with distance from the hypocenter, the condition of shielding, epilation, and the presence or absence or degree of radiation syndrome. (N.K.)

  17. Atomic Bomb Health Benefits

    Luckey, T.D.

    2008-01-01

    Media reports of deaths and devastation produced by atomic bombs convinced people around the world that all ionizing radiation is harmful. This concentrated attention on fear of miniscule doses of radiation. Soon the linear no threshold (LNT) paradigm was converted into laws. Scientifically valid information about the health benefits from low dose irradiation was ignored. Here are studies which show increased health in Japanese survivors of atomic bombs. Parameters include decreased mutation,...

  18. Atomic bomb and leukemia

    Characteristic features of the leukemia among atomic bomb survivors were studied. Dose estimates of atomic bomb radiation were based on T65D, but the new dosimetry system DS86 was used for some analyses. The ratio of a single leukemia type to all leukemias was highest for chronic myelogenous leukemia (CML) in Hiroshima, and the occurrence of CML was thought to be most characteristic to atomic bomb radiation induced leukemia. The threshold of CML occurrence in Hiroshima is likely to be between 0.5∼0.09 Gy. However, the threshold of acute leukemia appears to be nearly 1 Gy. In the distribution of acute myeloid leukemia (AML) subtypes by French-American-British classification, there was no M3 case in 1 Gy or more group, although several atypical AML cases of survivors were observed. Although aplastic anemia has not increased as a late effect of the atomic bomb radiation exposure, many atypical leukemia or other myeloproliferative diseases who had been diagnosed as aplastic anemia or its related diseases have been experienced among atomic bomb survivors. Chromosome study was conducted using colony forming cells induced by hemopoietic stem cells of peripheral blood of proximal survivors. Same chromosome aberrations were observed in colony forming cells and peripheral T-cells in several atomic bomb survivors. (author)

    2012-01-01

    Full Text Available Purpose: To present the visual outcomes and ocular sequelae of victims of cluster bombs. Materials and Methods: This retrospective, multicenter case series of ocular injury due to cluster bombs was conducted for 3 years after the war in South Lebanon (July 2006. Data were gathered from the reports to the Information Management System for Mine Action. Results: There were 308 victims of clusters bombs; 36 individuals were killed, of which 2 received ocular lacerations and; 272 individuals were injured with 18 receiving ocular injury. These 18 surviving individuals were assessed by the authors. Ocular injury occurred in 6.5% (20/308 of cluster bomb victims. Trauma to multiple organs occurred in 12 of 18 cases (67% with ocular injury. Ocular findings included corneal or scleral lacerations (16 eyes, corneal foreign bodies (9 eyes, corneal decompensation (2 eyes, ruptured cataract (6 eyes, and intravitreal foreign bodies (10 eyes. The corneas of one patient had extreme attenuation of the endothelium. Conclusions: Ocular injury occurred in 6.5% of cluster bomb victims and 67% of the patients with ocular injury sustained trauma to multiple organs. Visual morbidity in civilians is an additional reason for a global ban on the use of cluster bombs.

  20. Are IRIS Bombs Connected to Ellerman Bombs?

    Tian, Hui; Xu, Zhi; He, Jiansen; Madsen, Chad

    2016-06-01

    Recent observations by the Interface Region Imaging Spectrograph (IRIS) have revealed pockets of hot gas (∼2–8 × 104 K) potentially resulting from magnetic reconnection in the partially ionized lower solar atmosphere (IRIS bombs; IBs). Using joint observations between IRIS and the Chinese New Vacuum Solar Telescope, we have identified 10 IBs. We find that 3 are unambiguously and 3 others are possibly connected to Ellerman bombs (EBs), which show intense brightening of the extended {{{H}}}α wings without leaving an obvious signature in the {{{H}}}α core. These bombs generally reveal the following distinct properties: (1) the O iv 1401.156 Å and 1399.774 Å lines are absent or very weak; (2) the Mn i 2795.640 Å line manifests as an absorption feature superimposed on the greatly enhanced Mg ii k line wing; (3) the Mg ii k and h lines show intense brightening in the wings and no dramatic enhancement in the cores; (4) chromospheric absorption lines such as Ni ii 1393.330 Å and 1335.203 Å are very strong; and (5) the 1700 Å images obtained with the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory reveal intense and compact brightenings. These properties support the formation of these bombs in the photosphere, demonstrating that EBs can be heated much more efficiently than previously thought. We also demonstrate that the Mg ii k and h lines can be used to investigate EBs similarly to {{{H}}}α , which opens a promising new window for EB studies. The remaining four IBs obviously have no connection to EBs and they do not have the properties mentioned above, suggesting a higher formation layer, possibly in the chromosphere.

    The T-11M lithium program is focused to find solutions for technological issues of a steady-state tokamak. A recent lithium activity in T-11M was focused on three directions: investigation of different Li-limiters, investigations of long-term effects of lithium behavior in hydrogen plasmas and development of a new kind of CPS limiters. The new so-called R limiter has been used as Li collector for investigation of lithium fluxes near the plasma boundary and chamber walls. It was shown, that the Li circulation near the limiter exceeds up to four times the primary lithium flux from limiters. 90% of primary flux is collected by lateral sides of limiter and only 10% arrives at the chamber wall. The deuterium glow discharge was used to test the long-term lithium degradation under the deuterium bombardment. It was shown that such degradation is small. That means that the Li-limiter can be used as Li-emitter in steady-state tokamak operation. A new vertical lithium limiter was successfully tested in T-11M.

    Full Text Available Los avances en la difusión de la Sociedad de la Información en España y en el conjunto de la Unión Europea han sido extraordinarios, sobre todo en lo que respecta al equipamiento y a la conectividad. A día de hoy, tres de cada cuatro hogares en la Unión Europea están conectados a la Red, lo que nos lleva a reflexionar acerca de la superación de la Brecha Digital tradicional tal y como se había entendido hasta ahora. Pero este hecho no implica que la Sociedad de la Información esté plenamente difundida, dado que la verdadera revolución de las nuevas tecnologías no va a tener lugar con una masa social que únicamente haga uso de sus servicios más básicos, sino con aquellos que puedan llegar a producir innovación y conocimiento, y por el momento, esa masa social es aún muy reducida. En el presente artículo se analiza cómo pueden contribuirlas nuevas tecnologías en el proceso de configuración de las Smart Cities. Para ello se estudian el consumo de servicios avanzados tanto por parte de los ciudadanos como del sector empresarial en las comunidades autónomas de Galicia y Madrid.

    The issue of human bombing, which is popularly known as suicide bombing has become important in the Western world since the 9/11 and 7/7 attacks. Since then the issue of human bombing has become important to academia, the media, and security experts. This interest has resulted in much literature attempting to explain why human bombings take place and what motivates the bombers; for instance, the works of Gambetta (2006); Pape (2006); Merari (2010); Hafez (2006, 2007); Wright (2007); Bloom (20...

    The historical background of U.S. neutron bomb research and a brief history of the bomb are presented. The two important characteristics of neutron bombs, i.e. enhanced radiation and low burst yield, are explained in detail, and a comparison with common fission bombs is given. The physical principles are explained, i.e. the neutron bomb is a specially designed hydrogen bomb in which energetic neutrons released in the fusion of deuteron and triton is the main injurious factor. Finally, the functions and limitations of neutron bombs as well as the means of protection against them are discussed

  9. Detection of Logic Bombs

    Ankur Singh Bist

    2014-02-01

    Full Text Available Computer viruses are big threat to computer world; researchers doing work in this area have made various efforts in the direction of classification and detection methods of these viruses. Graph mining, system call arrangement and CFG analysis are some latest research activities in this field. The computability theory and the semi computable functions are quite important in our context of analyzing malicious activities. A mathematical model like random access stored program machine with the association of attached background is used by Ferenc Leitold while explaining modeling of viruses in his paper. Computer viruses like polymorphic viruses and metamorphic viruses use more efficient techniques for their evolution so it is required to use strong models for understanding their evolution and then apply detection followed by the process of removal. Code Emulation is one of the strongest ways to analyze computer viruses but the anti-emulation activities made by virus designers are also active. This paper involves the study of logic bombs.

  14. Neutron bomb and European defense

    France's development of the controversial neutron bomb is in line with the US goal of flexible response to a Soviet threat in Europe. US neutron bomb production is on a standby basis pending agreement among the North Atlantic Treaty Organization (NATO) members for deployment. Controversy over the bomb centers on its anti-personnel nature, which many see as immoral in comparison with weapons that primarily damage property. Opponents also see it as lowering the nuclear threshold and increasing the chance of nuclear war. Supporters view the bomb as a tactical weapon to be used on a limited scale as a last resort. If Germany's Chancellor Schmidt fails to negotiate a limit to European nuclear arms deployment with the Soviet Union, neutron-bomb production in the US and France will most likely proceed. The prospects for including European nuclear weapons in the Strategic Arms Limitation Talks (SALT) III are jeopardized by the Soviet invasion of Afghanistan and the failure of an early SALT II ratification. 17 references

    The Comunidad Autonoma de Madrid (Autonomous Community of Madrid, in the following Madrid Region), is a region located at the geographical centre of the Iberian Peninsula. Its area is 8.028 km{sup 2}, and its population about five million people. The Department of Economy and Technological Innovation of the Madrid Region, together with some organizations dealing on energy saving and other research institutions have elaborated an Energy Plan for the 2004-12 period. As a part of this work, the Fluid Mechanics Laboratory of the Superior Technical School of Industrial Engineers of the Polytechnic University of Madrid has carried out the assessment of the wind energy resources [Crespo A, Migoya E, Gomez Elvira R. La energia eolica en Madrid. Potencialidad y prospectiva. Plan energetico de la Comunidad de Madrid, 2004-2012. Madrid: Comunidad Autonoma de Madrid; 2004]; using for this task the WAsP program (Wind Atlas Analysis and Application Program), and the own codes, UPMORO (code to study orography effects) and UPMPARK (code to study wake effects in wind parks). Different kinds of data have been collected about climate, topography, roughness of the land, environmentally protected areas, town and village distribution, population density, main facilities and electric power supply. The Spanish National Meteorological Institute has nine wind measurement stations in the region, but only four of them have good and reliable temporary wind data, with time measurement periods that are long enough to provide representative correlations among stations. The Observed Wind Climates of the valid meteorological stations have been made. The Wind Atlas and the resource grid have been calculated, especially in the high wind resource areas, selecting appropriate measurements stations and using criteria based on proximity, similarity and ruggedness index. Some areas cannot be used as a wind energy resource mainly because they have environmental regulation or, in some cases, are very close

    Lyon, Richard E

    2015-12-01

    The thermal dynamics of bomb calorimeters are modeled using a lumped heat transfer analysis in which heat is released in a pressure vessel/bomb immersed in a stirred water bath that is surrounded by a static air space bounded by an insulated (static) jacket, a constant/controlled temperature jacket (isoperibol), or a changing temperature (adiabatic) jacket. The temperature history of the water bath for each of these boundary conditions (methods) is well described by the two-term solution for the calorimeter response to a heat impulse (combustion), allowing the heat transfer coefficients and thermal capacities of the bomb and water bath to be determined parametrically. The validated heat transfer model provides an expression for direct calculation of the heat released in an arbitrary process inside a bomb calorimeter using the temperature history of the water bath for each of the boundary conditions (methods). This result makes possible the direct calculation of the heat of combustion of a sample in an isoperibol calorimeter from the recorded temperature history without the need for semi-empirical temperature corrections to account for non-adiabatic behavior. Another useful result is that the maximum temperature rise of the water bath in the static jacket method is proportional to the total heat generated, and the empirical proportionality constant, which is determined by calibration, accounts for all of the heat losses and thermal lags of the calorimeter.

  1. Bomb pulse radiocarbon dating

    Modern forensic science has to deal not only with homicides and other traditional crimes but also with more global threats such as the smuggling of nuclear materials, clandestine production of weapons of mass destruction, stockpiling of illicit drugs by state controlled groups and war crimes. Forensic applications have always benefited from the use of advanced analytical tools that can characterize materials found at crime scenes. In this paper we will discuss the use of accelerator mass spectrometry (AMS) as an ultrasensitive tool for the crime laboratories of the third millennium. An important objective in forensic science is to order past events chronologically by analysing materials associated with criminal actions. Radiocarbon dating is known to the general public for its application to historical and prehistorical investigations. Examples of forensic significance include the assassination of the Inca Atahualpa by Francisco Pizarro in the early 1530s, the possible murder of the Tyrolean Ice Man (Oetzi) 5300 years ago and the analysis of the burial cloths allegedly associated with the crucifixion of Jesus Christ . Recent murders, including those associated with war crimes in the Balkans during the 1990s, can be studied using 14C bomb pulse dating. This method has other forensic applications, including investigation of frauds related to food and wine counterfeiting, dating of opium crops and dating of substances used in biological warfare. AMS extends the applicability of the radiocarbon method, allowing the analysis of 14C in submilligram organic samples. Specific molecular compounds extracted from bones, hair, skin and other carbon bearing substances of forensic significance can now be dated, enhancing the sensitivity and reliability of chronological determinations. AMS can also be used to analyse rare actinide isotopes released into the environment during the clandestine production of nuclear weapons or associated with the smuggling of nuclear materials. In

  2. Neutron bomb and detente policy

    The author examines the strategic aspects of the neutron weapon, i.e. of those problems which result from the discussion on the neutron weapon and its connection with military detente. He discusses the events that happened until President Carter decided to delay the production of the neutron bomb. Furthermore, he examines its strategic function following this decision. He points out the problematic relationship between production and emplacement decision. Since the neutron bomb - according to its construction - will only be effective if it is located in Central Europe and primarily in the Federal Republic of Germany, the latter has to bear the final responsibility. Without a decision on its emplacement, there could be no decision in favour of its production. (HSCH)

  3. Unknown effects of neutron bombs

    Questions surrounding the use of the neutron bomb as a tactical weapon are considered. In particlar the problem of what would happen to troops exposed to neutron bomb radiation is examined. The use of a 1 kilotonne enhanced radiation warhead, to WD-70 mod 3, detonated at a height of 130-200 metres would destroy buildings only 130 metres from a point below where it is detonated but the entire 1000 people in a tank crew in that area would receive lethal doses of radiation although some would not die for more than a month following exposure. All would however begin to suffer various forms of radiation sickness. The effect over time of whole-body radiation doses of 200 to 18000 rads for physically demanding work are shown graphically. The problem of treating the wounded and of reoccupying areas of high residual radiation are discussed. (U.K.)

  5. The media and dirty bombs

    During the recent Jose Padilla 'dirty bomb' scare, an indignant US citizen wrote to his local newspaper in Florida complaining that the news media were giving terrorists a recipe for making dirty bombs. 'Unless the media eases up on scaring us, he wrote, the public won't feel safe even leaving their homes. Or perhaps that is what they want, he said, 'us staying inside our homes watching the news on how terrorists can destroy us all.' It seems our real motivations have finally been uncovered we in the media want to scare them so much they won't leave their TV screens. Based on the previous event an analysis of the role of media and journalists is discussed. Leaders of the news media would, first of all, universally advise full and rapid and authoritative disclosure of what is known. If it isn't coming quickly from the highest levels, then the news will soon deteriorate to what's being heard on the streets, from police officers and fire fighters and other emergency personnel, and from passers-by. Journalists are the first to acknowledge their ignorance.That is why they ask questions. However, they seem to learn fast. It was found that that the term dirty bomb never appeared on Associated Press news wires before the 11 September 2001 attacks. Now it appears every day, and increasingly we are getting the facts right and helping to prepare our audience of millions for this dangerous new world

    Radiation has been associated with increases in noncancerous diseases. An effect of low-dose radiation on the prevalence of clinically detected glaucoma has not been previously reported. We therefore investigated the prevalence of glaucoma in A-bomb survivors and its possible association with radiation dose. A total of 1,589 people who participated in the clinical examination program for A-bomb survivors at the Radiation Effects Research Foundation (RERF) between October 2006 and September 2008 and who had reconstructed radiation doses, were recruited into this cross-sectional screening study. The prevalence of glaucoma and its dose-response relationship to A-bomb radiation were measured. Each subject underwent an initial screening consisting of an interview and ophthalmological examination. Questionable cases with any indication of ocular disease, including glaucoma, were referred to local hospitals for more comprehensive evaluation. A diagnosis of glaucoma was made based on specific optic disc appearance, perimetric results and other ocular findings. Of 1,589 eligible people, we detected 284 (17.9%) cases of glaucoma overall, including 36 (2.3%) cases of primary open-angle glaucoma with intraocular pressure levels greater than 21 mmHg, 226 (14.2%) cases of normal-tension glaucoma and 25 (1.6%) cases of primary angle-closure glaucoma. Seven glaucoma risk factors were examined as potential confounders but only two needed to be included in the final model. Binary regression using a generalized estimating equation method, with adjustment for gender, age, city, cataract surgery or diabetes mellitus, revealed an odds ratio at 1 Gy of 1.31 (95% confidence interval 1.11-1.53, P = 0.001) in the case of normal-tension glaucoma, but no association for other types of glaucoma. The prevalence of normal-tension glaucoma may increase with A-bomb radiation dose, but uncertainties associated with nonparticipation (59% participation) suggest caution in the interpretation of these

    Was the atomic bombing of Hiroshima and Nagasaki justified? Was it necessary? Were there other - better - options available, either to the scientists who built the bombs or the generals who ordered them dropped? Nearly 70 years later, there are still no settled answers to these questions, and Tom Morton-Smith's new play Oppenheimer wisely avoids dwelling on the "what ifs" of atomic history.

  18. Atomic bombs and conspiracy theories

    There have been a number of articles in the press concerning Australia's bid to get the atomic bomb. These articles are based on the recent publication of a book, 'Australia's Bid for the Bomb' by Wayne Reynolds. The book at first sight appears to be very well researched, with many archival references from a number of countries, and the hypotheses appear to be well supported and argued. Its major shortcoming is the way that the science and technology involved is presented. The author seems to have a complete lack of understanding of basic science and engineering principles, and the manner in which scientists and politicians communicate with each other. This paper will attempt to redress these shortcomings, I shall look at the way communities of scientists and politicians present their ideas to each other and to the public at large. By investigating the backgrounds to the establishment of the Snowy Mountains Scheme and the later establishment of the Australian Atomic Energy Commission, the author is able to explain how such a hypothesis ever saw the light of day

  1. Mortality among atomic bomb survivors

    The Atomic Bomb Casualty Commission and its successor, the Radiation Effects Research Foundation, have conducted a long-term follow-up study of a cohort of 120,000 atomic bomb survivors and non-exposed controls since 1950. The most recent findings regarding cancer mortality during the period 1950-85 in this cohort, based on the DS86 doses are as follows: The dosimetry change does not alter the list of radiation-related cancers. Some city differences in dose-response previously thought to be real are no longer significant with the DS86 doses. Assuming a linear dose-response, and using estimated organ-absorbed doses, the risk coefficients derived from the two dosimetries are very similar. If larger RBE values are assumed, the disparity between the two dosimetries increases because the neutron dose is much greater in the T65 dosimetry. Besides the well-known increase of leukemia, there also have been demonstrated increases in cancers of the lung, breast, esophagus, stomach, colon, ovary, urinary bladder, and of multiple myeloma, but no increase has yet been observed in mortality from cancer of the rectum, gallbladder, pancreas, prostate and uterus, and of malignant lymphoma. In general, radiation-induced solid cancer begins to appear after attaining the age at which cancer is normally prone to develop (the so-called 'cancer age'), and continues to increase proportionately with the increase in mortality in the control group as it ages. Sensitivity to radiation, in terms of cancer induction, is higher generally for persons who were young at the time of the bomb (ATB) than for those who were older ATB. Non-cancer mortality in the period 1950-78, based on the T65 doses, which is the most recent published report, did not show an increase with dose, but now, with the accumulation of seven more years of follow-up, there seems to be an excess in the very high dose range, particularly for the younger age ATB cohort.

  2. How Dangerous are 'Dirty Bombs'?

    A radiological weapon (or a radiation weapon) is any weapon that is designed to spread radioactivity, either to kill, or to deny the use of an area (a modern version of salting the earth) and consists of a device (such as a nuclear or conventional explosive), which spreads radioactive material. Recently, it has been called 'dirty bombs'. This term refers especially to a weapon that would disperse radioactive material through conventional explosives. The term was put in focus in June 2002, when U. S. officials announced they had captured an al-Qaida terrorist in Chicago who was allegedly planning for such a device. Designed to produce radiation sickness in a military force or a civilian population instead of destroying a target, Iraq developed and tested radiation weapons in 1980s, during the war with Iran with intention to produce health effects that would be difficult to explain. The project was abandoned because a radiation levels low enough to escape detection were also insufficient to cause significant medical problems in the weeks following an attack. Radiological weapons are therefore widely considered to be militarily useless for a state-sponsored army and are not believed to have been deployed by any military forces. However, these weapons have been suggested as a possible terror weapon in order to create fear and panic in densely populated areas and havoc to local economies. They do not require weapons-grade materials, and common materials such as 137Cs used in radiological medical equipment, could be used. Subsequent removal of urban radioactive contamination, i.e. cleanup efforts according to experiences from the radiological accident in a Brazilian city of Goiania could be long, difficult and costly. Therefore, the overall effects of exploded dirty bombs are hard to assess considering that: a) The health effects of low-level radiation are hotly contested. Namely, according to 'linear, no-threshold' dosimetric model, any increase over background is

    1969-02-01

    Full Text Available Work on five underground parking sites in Madrid was initiated in September 1967. These parking sites were rented by the Madrid Town Council to the firm Estacionamientos Subterráneos, S. A. The engineering, design, and traffic and construction planning of these parking sites was allocated to Viales y Estacionamientos, S. A., whilst the actual construction was carried out by the firm Huarte y Cía., S. A. The five parking sites were located at the Paseo Calvo Sotelo, Plaza del Marqués de Salamanca, Plaza Mayor, Plaza de las Cortes and at Calle de Fuencarral, all within the centre of Madrid. These projects are of special interest, since each design represents an advance with respect to the earlier ones in regard to their structural and functional arrangements, with a view to achieving easier construction and less interference with road and pedestrian traffic. In the present article a description is given of each the five parking sites, following the sequence of their construction, which corresponds to the order in which they were design and planned.En septiembre de 1967 comenzaron las obras de cinco estacionamientos subterráneos en Madrid, adjudicadas por el Ayuntamiento en régimen de concesión a Estacionamientos Subterráneos, S.

  5. Neuropsychiatric and psychologic effects of A-bomb radiation

    Few studies have assessed the influences of A-bombing from both psychiatric and psychologic points of view. This chapter deals with the knowledge of neuropsychiatric and psychologic influences of A-bombing. Many A-bomb survivors were exposed not only to radiation but also to rapid environmental alterations, such as death of family members and destruction of living. In addition, they suffered from sequelae and anxiety. Naturally, these were considered to cause psychological disturbance including autonomic imbalance and neurosis. Psychological survey, made immediately after A-bombing, is presented, with special attention to behavioral patterns in 54 A-bomb survivors by dividing them into 5 stimulation groups. Radiation syndrome occurring early after exposure and leukemia or cancer occurring later were referred to as 'Genbaku-sho' (A-bomb disease). A-bomb survivors' physically eventful conditions tended to induce mental anxiety or the contrary. Depression and phobia seemed to have correlated with physical conditions. In addition to 'A-bomb disease', mass media, dealing with 'A-bomb neurosis,' 'marriage in A-bomb survivors,' 'suicide in A-bomb survivors,' 'A-bomb survivors orphan,' and 'lonely old A-bomb survivors,' had a great impact on A-bomb survivors. For in uterus exposed and infantile A-bomb survivors, there was no significant difference between the exposed and non-exposed groups, although the incidence of eye tremor and sleeping disorder is found to be higher in the in uterus exposed group than the control group.

    Highlights: ► We investigated the Li collection by different type of limiters intersecting the scrape-of-layer (SOL) of T-10 and T-11M tokamaks. ► The analysis of the sample-witnesses located on T-11M limiters showed, that 60 ± 20% of the lithium injected during plasma operating of T-11M had been collected by limiters. ► We believe that is the real opportunity of the tokamak plasma facing components (PFC) development on the basis of liquid lithium circulation. - Abstract: The concept of a steady state tokamak with plasma facing components (PFC) on the basis of liquid lithium circulation demands the decision of three tasks: lithium injection to the plasma, lithium ions collection before their deposition on the vacuum vessel and lithium returning to the injection zone. Main subject of paper is the investigations of Li collection by different types of limiters intersected the scrape-of-layer (SOL) in T-10 and T-11M tokamaks. For finding solution for this problem in T-11M and T-10, experiments have been applied with Li-, C-rail limiters and ring SS R-limiter-collector (T-11M). The efficiency of Li collection by limiters in T-11M and T-10 tokamaks was investigated by post mortem sample–witness analysis and (T-11M) by the use of the mobile graphite probe (limiter) as a recombination target in the stream of lithium ions. The characteristic depth of lithium penetration in the SOL area of T-11M is about 2 cm and 4 cm in SOL of T-10. The quantitative analysis of the sample–witnesses located on T-11M limiters showed that 60 ± 20% of the lithium injected during plasma operating of T-11M had been collected by limiters. It confirms an opportunity of the lithium ions collection by limiters in tokamak SOL.

  10. UV spectra, bombs, and the solar atmosphere

    Judge, Philip G

    2015-01-01

    A recent analysis of UV data from the Interface Region Imaging Spectrograph {\\em IRIS} reports plasma "bombs" with temperatures near \\hot{} within the solar photosphere. This is a curious result, firstly because most bomb plasma pressures $p$ (the largest reported case exceeds $10^3$ dyn~cm$^{-2}$) fall well below photospheric pressures ($> 7\\times10^3$), and secondly, UV radiation cannot easily escape from the photosphere. In the present paper the {\\em IRIS} data is independently analyzed. I find that the bombs arise from plasma originally at pressures between $\\lta80$ and 800 dyne~cm$^{-2}$ before explosion, i.e. between $\\lta850$ and 550 km above $\\tau_{500}=1$. This places the phenomenon's origin in the low-mid chromosphere or above. I suggest that bomb spectra are more compatible with Alfv\\'enic turbulence than with bi-directional reconnection jets.

  17. Urban pest management. A Madrid case study

    Ibon Tamayo Uria

    2013-06-01

    Full Text Available Citizens’ reports of sightings of undesirable animals are a common component of pest control programmes in a city. For this reason, local authorities tend to develop procedures for the capture and analysis of the resulting data sets based on these reported sightings. These procedures in turn contribute to the development of other initiatives aimed at improving public health conditions. The study presented here focuses on the methodology designed and implemented by the Madrid City Council for controlling and managing the presence of urban pests.The long experience (over 100 years of the City Council and its commitment to the incorporation of new technologies have allowed a number of important lessons to be learnt in pest control and management, which may be useful as a guide and model for cities where public health services have not yet incorporated these methods.

  18. Vehicle bomb protection for nuclear power plants

    The six-step methodology presented in this paper can be applied to nuclear power reactors to provide protection measures and considerations against vehicle bomb threats. The methodology provides a structured framework for examining the potential vulnerability of a plant to a postulated vehicle bomb and for developing contingency planning strategies for dealing with such a possibility. The six steps are as follows: (1) identify system options available to establish and maintain a safe reactor shutdown; (2) identify buildings or other structures containing critical components and equipment associated with each system option; (3) determine survival envelopes for the system options; (4) review site features to determine vehicle access approach paths and distances as they relate to the survival envelopes; (5) identify measures to limit or thwart vehicle access, and protect and preserve preferred system options; (6) prepare contingency plans and make advance arrangements for implementation of contingency measures for a vehicle bomb attack. Portions of this methodology related to blast effects from vehicle bombs on power reactor components are implemented using BombCAD, a proprietary computer-aided design (CAD)-based blast effects analysis technique

  19. Colorectal cancer among atomic bomb survivors

    Studies on autopsied and surgical cases of colorectal cancer in Hiroshima and Nagasaki atomic bomb (A-bomb) survivors have not shown a relationship to radiation. In a recent epidemiologic study made on a fixed population at the Radiation Effects Research Foundation (RERF), the risk of colon cancer was found to increase significantly with increasing radiation dose in both Hiroshima and Nagasaki, and also in both males and females. The dose effect for the cities and sexes combined was especially pronounced for cancer of the sigmoid colon. The effect of radiation was found to vary by age at the time of the bomb (ATB) and the effect was remarkable among those under age 20 ATB. The risk of rectal cancer was not found to increase significantly with radiation and the distribution of histological types for cancer of either the colon or rectum was unrelated to radiation dose. The effect of A-bomb exposure on the postoperative survival rate for colorectal cancer patients was studied. No difference by radiation dose could be demonstrated. In Japan, the incidence of colorectal cancer, and of colon cancer in particular, has been increasing. Therefore, close attention should be paid to changes occuring in A-bomb survivors

  1. Thermal analysis of pyrotechnic mixture-fireworks, atom-bomb

    Sound level produced from two varieties of sound producing fireworks of atom-bomb, cake bomb and thunder bomb were measured. The pyrotechnic mixture, KNO3/S/Al(H3BO3) of compositions 57.5/19.9/22.1(0.5)% very much similar to commercial atom-bomb were taken and five cake bomb and seven thunder bomb with different net weight of chemicals were manufactured specifically for analysis. Cake bomb with 1g pyrotechnic mixture and thunder bomb with 2g pyrotechnic mixture produce -3. Ignition temperature of the mixture is above the melting point of the metallic fuel, Al (660 deg C) and self propagating decomposition occurred at high temperature. The pyrotechnic mixture, KNO3/S/Al(H3BO3) is a safe mixture from accidental factor, static electricity. DSC studies indicate slight formation of potassium nitrite with evolution of NO above 400 deg C. (author)

  2. The impact of the A-bomb

    Forty years after the throwing of the atomic bombs on Hiroshima and Nagasaki this book is published as the expression of a profound longing for peace and disarmament. It is based on a comprehensive compilation of results published in 1979; it sums up the main parts of that work and adds new materials which illustrate the actual conditions at the time of the bombing. The experience of Hiroshima and Nagasaki is to become the joint possession of all peoples and to enhance the commitment of mankind to peace. The individual chapters describe the devastations, atomic destruction, the victims who suffered injuries, the acute stage of the A-bomb disease, scars that failed to heal, the survivors, life in the ruins, medical care and assistance, the search for peace, the path to a world without nuclear arms.

  6. Forensic Seismology: constraints on terrorist bombings

    Wallace, T. C.; Koper, K. D.

    2002-05-01

    Seismology has long been used as a tool to monitor and investigate explosions, both accidental and intentional. Seismic records can be used to provide a precise chronology of events, estimate the energy release in explosions and produce constraints to test various scenarios for the explosions. Truck bombs are a popular tool of terrorists, and at least two such attacks have been recorded seismically. On August 7, 1998 a truck bomb was detonated near the US embassy in Nairobi, Kenya. The bomb seriously damaging a dozen buildings, injuring more than 4000 people and causing 220 fatalities. The explosion was recorded on a short-period seismometer located north of the blast site; the blast seismogram contained body waves, Rayleigh waves and vibrations associated with the air blast. Modeling of the body and surfaces wave allowed an estimate of the origin time of the bombing, which it turn could be used as a constraint the timing of the air blasts. The speed of the air waves from an explosion depend on the air temperature and the size, or yield, of the explosion. In an effort to fully utilize the seismic recordings from such attacks, we analyzed the seismic records from a series of controlled truck bomb explosions carried out at White Sand Missile Range in New Mexico. We developed a new set of scaling laws that relate seismic and acoustic observations directly to the explosive mass (yield). These relationships give a yield of approximately 3000 kg of TNT equivalent for the Nairobi bomb. The terrorist bombing of the Murrah Federal Building in Oklahoma City in 1995 was also recorded on seismometers. One of these records showed 2 discrete surface wavetrains separated by approximately 10 seconds. Some groups seized on the seismic recordings as evidence that there were 2 explosions, and that the US government was actually behind the bombing. However, the USGS monitored the demolition of the remainder of the Murrah Building and showed that the collapse also produced 2 surface

    Piezoelectric ultrasonic transducer, energized by frequency generator and power supply, vibrates shell of pipe bomb while hardly disturbing explosive inner material. Frequency-control circuitry senses resonance in shell and holds generator at that frequency to induce fatigue cracking in threads of end cap. In addition to disarming bombs, ultrasonically induced fatigue may have other applications. In manufacturing, replaces some machining and cutting operations. In repair of equipment, cleanly and quickly disassembles corroded parts. In demolition of buildings used to dismember steel framework safely and controllably.

  12. SUPER-SABRE: an RSX-11M system for generalized gamma-ray spectroscopy

    A system is described which provides generalized multi-user services for gamma-ray spectrometry with an existing laboratory computer. Purpose-built hardware is not employed. The current implementation is on a PDP11 computer under RSX-11M using commercial CAMAC units. The design, however, is not limited to specific hardware. Up to fourteen operators may use eight detectors or access an archive of many thousand spectra. An interactive command language is supplemented by a command file interpreter. A user may control data acquisition, manipulate, examine or analyze spectra. There is complete flexibility and independence in the use of terminals and other devices. SUPER-SABRE demonstrates particular features of computer-user interface design and provides test-bed facilities for analytical procedures within its software. It is capable of extension and modification to accommodate appropriate developments in computer technology. The current system is successfully employed in the measurement of environmental radioactivity, for radiation protection plant control and for neutron activation analysis

  17. Health risks of atomic bomb survivors

    At the Atomic Bomb Casualty Commission and its successor organization, the Radiation Effects Research Foundation, mortality and morbidity surveys have been continually carried out on about 1,800 persons exposed in utero to the atomic bombings of Hiroshima and Nagasaki. Although the effect of radiation exposure was marked enough to permit observation of a dose-response relationship in the 30 known cases of severe mental retardation among the in utero-exposed, the association between in utero exposure and cancer risk is still uncertain. Based on data for all cancers from 1950 through 1984 for the in utero-exposed, the excess risk per 10,000 person-year-Gy was 6.57 and the relative risk at 1 Gy was 3.77. For the recent years 1985-89, there was no evident excess of cancer risk. During the remaining lifetime, it seems unlikely that any great excess of leukemia will appear. As for the risk of solid tumors, further follow up is in progress. The 1950-89 findings for cancer risk among the in utero-exposed will be compared with cancer risk among A-bomb survivors who were less than 10 years old at the time of the bombings. (author)

  18. Reassessment of Atomic Bomb radiation dosimetry

    Extensive work has been conducted over the past several years to reassess all aspects of the radiation dosimetry for the A-bombs in Hiroshima and Nagasaki. This work has included reviews of the bomb yields, source terms, air transport of neutrons and gamma rays, neutron-induced radioactivity and thermoluminescence produced by gamma rays in exposed materials, shielding of individuals by buildings, and calculations of organ doses. The results of these theoretical and experimental activities have led to the development of a new dosimetry system which is designated as the Dosimetry System 1986 (DS86). To be useful in radiation risk assessment, DS86 must be individualized or applied to the assertions of particular individuals as to their whereabouts at the time of the bombing. New DS86 estimates, in terms of tissue kerma in air and absorbed dose to fifteen organs, are available for 106,001 of the 141,635 individuals in current follow-up study populations. For the other individuals, it has been impossible to make DS86 estimates for 9,026 exposed individuals, and there are 26,608 unexposed individuals who were not in either city at the time of bombing. The DS86 estimates are discussed and compared with early dose estimates which were designated as Tentative 1965 Doses (T65D) and were used as a basis for radiation risk assessment throughout the 1970's

    The principle of thermonuclear reaction is explained and the destructive action is briefly outlined of the projected neutron bomb. Using the Hiroshima and Nagasaki nuclear explosions as a warning of the consequences of the misuse of nuclear energy, an appeal is made for disarmament as the sole safeguard of peace. (L.O.)

  20. Development of A-bomb survivor dosimetry

    An all important datum in risk assessment is the radiation dose to individual survivors of the bombings in Hiroshima and Nagasaki. The first set of dose estimates for survivors was based on a dosimetry system developed in 1957 by the Oak Ridge National Laboratory (ORNL). These Tentative 1957 Doses (T57D) were later replaced by a more extensive and refined set of Tentative 1965 Doses (T65D). The T65D system of dose estimation for survivors was also developed at ORNL and served as a basis for risk assessment throughout the 1970s. In the late 1970s, it was suggested that there were serious inadequacies with the T65D system, and these inadequacies were the topic of discussion at two symposia held in 1981. In early 1983, joint US- Japan research programs were established to conduct a thorough review of all aspects of the radiation dosimetry for the Hiroshima and Nagasaki A-bomb survivors. A number of important contributions to this review were made by ORNL staff members. The review was completed in 1986 and a new Dosimetry System 1986 (DS86) was adopted for use. This paper discusses the development of the various systems of A-bomb survivor dosimetry, and the status of the current DS86 system as it is being applied in the medical follow-up studies of the A-bomb survivors and their offspring

  1. The 'secureplan' bomb utility: A PC-based analytic tool for bomb defense

    This paper illustrates a recently developed, PC-based software system for simulating the effects of an infinite variety of hypothetical bomb blasts on structures and personnel in the immediate vicinity of such blasts. The system incorporates two basic rectangular geometries in which blast assessments can be made - an external configuration (highly vented) and an internal configuration (vented and unvented). A variety of explosives can be used - each is translated to an equivalent TNT weight. Provisions in the program account for bomb cases (person, satchel, case and vehicle), mixes of explosives and shrapnel aggregates and detonation altitudes. The software permits architects, engineers, security personnel and facility managers, without specific knowledge of explosives, to incorporate realistic construction hardening, screening programs, barriers and stand-off provisions in the design and/or operation of diverse facilities. System outputs - generally represented as peak incident or reflected overpressure or impulses - are both graphic and analytic and integrate damage threshold data for common construction materials including window glazing. The effects of bomb blasts on humans is estimated in terms of temporary and permanent hearing damage, lung damage (lethality) and whole body translation injury. The software system has been used in the field in providing bomb defense services to a number of commercial clients since July of 1986. In addition to the design of siting, screening and hardening components of bomb defense programs, the software has proven very useful in post-incident analysis and repair scenarios and as a teaching tool for bomb defense training

    Experimental results on boronization in situ in the tokamak T-11M plasma shots using non-toxic and not explosive metacarborane C{sub 2}H{sub 12}B{sub 10} are presented. As a result of boronization, the film with thickness up to 0.2 {mu}m at deposition rate {approx}25 nm/s was produced. The microhardness of the formed boron containing film H{sub 10} - 600, which indicates on structuredness of coating (the microhardness of the CVD B{sub 4}C films was H{sub 100} - 1800). Injection of carborane in the plasma shots has improved a stabilization of plasma filament. The impurities in wall area have been suppressed, high-vacuum characteristics of the discharge chamber were stabilized. Plasma shot duration without disruption increased essentially. At the density of n{sub e} = 1.3 x 10{sup 13} cm{sup -3}, I{sub p} = 70 kA a shot duration was 350 ms and at the density of n{sub e} = 4.65 x 10{sup 13} cm{sup -3}, I{sub p} = 70 kA was {approx}250 ms. High repeatability of experimental results has appeared. Boronization results in to an essential decrease of the volt-second consumption rate and, correspondingly, to an increase of shot duration. Developed technology opens an opportunity of practical production of renewed structured boron-carbon coatings using of plasma shots in existing large-scale tokamaks and plasma devices.

  3. Lung cancer among atomic-bomb survivors

    Patho-statistical study of the relationship between lung cancer and the atomic-bomb (A-bomb) was made on 259 lung cancer cases autopsied in Hiroshima Atomic Bomb Hospital between 1956 and 1983. These autopsy cases were divided into 3 groups; those exposed at 2000 m from the hypocenter or those entering the city after the bombing (group B), and non-exposed group. The incidence of lung cancer was high irrespective of sex in the group A, being 1.8 times higher than in the non-exposed group. It tended to increase rapidly since 1975 in women of the group A, and the ratio of women to men was high, as compared with the other groups. In the group B and the non-exposed group, the incidence of lung cancer tended to increase year by year, particularly in men. Grip-sized adenocarcinoma was seen more frequently in the group A than in the other groups. Squamous cell carcinoma and undifferentiated cancer occurred more frequently than adenocarcinoma in older women of the exposed groups. This seemed to be due to the fact that older patients tended to have squamous cell carcinoma or undifferentiated cancer more frequently than adenocarcinoma. The incidence of lung cancer, particularly adenocarcinoma, tended to increase in the exposed groups. There was no great difference in the incidence of organ metastasis between the exposed groups and non-exposed group. Twenty-one of 24 cases of multiple cancer were A-bomb victims, although the incidence of complications was independent of exposure status. (Namekawa, K.)

  4. Foreign bodies radiographically-demonstrated in atomic bomb survivors

    The prevalence of roentgenologically-detected foreign bodies among atomic bomb (A-bomb) survivors was studied as an indicator of the A-bomb blast effects. Acupuncture was studied as an indicator of A-bomb-related abnormalities for which it was administered. All Adult Health Study subjects' roentgenograms demonstrating foreign bodies were reviewed. The frequency of glass and metal, and acupuncture needles were analyzed by distance from hypocenters, sex, age, body sites involved; and the subjects' shielding at the times of the A-bombs. The presence of glass fragments correlated closely with distance from hypocenter, heavy shielding from the A-bombs, and with adulthood, and they were more frequent in the chest than hand and wrist. Metal foreign bodies were more frequent in the hand and wrist than in the chest, and not associated with distance from hypocenter or heavy shielding. The prevalence of acupuncture needles increased with age, but did not correlate with A-bomb dose. (author)

  6. Study of an anomalous pinch effect in the T-11M tokamak

    The peaked density profiles ne(r) are typical for tokamaks with ohmic heating. This contradicts to the fact that the sources of plasma - gas puffing and hydrogen recycling are localized in plasma periphery. Usually one try to resolve this contradiction by assumption of impurity accumulation or development of neoclassical Ware pinch or by supposition of its version - turbulence-driven particle pinch. In the T-11M experiments with Li-limiter, where impurity effects were excluded and plasma collisionality was rather high (ν*∼0.5), the peaked density profiles ne(r) have been observed also and this seems to be an evidence of plasma density accumulation (anomalous pinch effect). The measurements of ne(r) were carried out with help of five-channel jump-free Cotton-Mouton interferometer (polarimeter) using the conventional Abel-procedure. The ne(r) profiles can be approximated by set of parabolas: ne(r) = ne (0)·(1-r2/a2)α. The alpha parameter was an indicator of profile peaking and varied in range from 0.3 to ∼1.5. The analysis of experimental results showed that the formation of bell-shaped profile ne(r) with α∼1.5 in condition of internal gas puffing can take place only under strong plasma influx from the periphery to the plasma center (along the gradient of ne(r)) with velocity about of 3-4 m/s, which is 3-5 times more than assumed velocity of neoclassical Ware pinch. This effect does not depend on plasma purity and it is observed both with lithium and graphite limiters. Visible anomalous pinch effect increased following the growth of ne. Any assumptions about influence of direct flux of neutral atoms on creation of ne(r) profile are eliminated thereby. The development of convective transport processes from the periphery to the plasma core seems to be the most probable reason of peaked profiles ne(r) generated in conditions of a peripheral source.

    We analyzed the risk in 2,743 atomic bomb survivors by using a new dosimetry system. From the database, we selected 2,743 exposed persons and a total of three times 2,743 age-matched controls who were living far from the center of the A-bomb radiation in Nagasaki at the time of the explosion and who were still alive in 1971. The mortalities from all causes for male subjects exposed were slightly lower than, or almost equal to, those of unexposed persons. Death from cancer, however, increased in both sexes after all levels of irradiation except in males exposed to 0.01-0.49 Gy. In males, the risk was showed significant reduction in death from all diseases other than cancer classified according to 0.31-0.40 Gy. (author)

  9. Mass cancer survey of atomic bomb survivors

    This is an outcome of mass screening for breast and uterine cancers performed in A-bomb survivors during the period from August 1988 through March 1990. Among 1,770 participants in mass screening for breast cancer, detailed examination was judged to be necessary in 6.1%. The rate of participation in the subsequent examination was 81.5%. Breast cancer was detected in 6 patients, which was all invasive ductal carcinoma. The estimated detection rate for breast cacer was 0.47%. There were 1,648 participants in mass screening for uterine cancer. The rate of detailed examination required was 2.0%, and the rate of participation was 66.7%. Uterine cancer was detected in 5 A-bomb survivors, one of whom had metastasis of rectal cancer. The estimated detection rate was 0.45%. (N.K.)

  11. Cancer risk among atomic bomb survivors

    The Radiation Effects Research Foundation (RERF) and its predecessor, the Atomic Bomb Casualty Commission (ABCC), has been conducting a long-term follow-up of a cohort of the atomic bomb survivors in Hiroshima and Nagasaki. The continuing follow-up of this population, known as the Life Span Study (LSS) cohort, has been a major source of epidemiological data for radiation risk assessment. Periodic analyses of the LSS mortality data have resulted in a series of reports that describe and quantify radiation effects on cancer mortality. More recently, a series of comprehensive reports of cancer incidence for this cohort has also been published. The latest report on the LSS cancer mortality data through 1990 will soon be published. The purpose of this presentation is to provide an updated overview of the LSS cancer and leukemia data. (author)

  13. Risk of cancer among atomic bomb survivors.

    Shimizu, Y; Kato, H; Schull, W J

    1991-12-01

    This report describes the risk of cancer and in particular cancers other than leukemia among the survivors of the atomic bombing of Hiroshima and Nagasaki. Attention focuses primarily on the risk of death from cancer among individuals in the Life Span Study sample of the Radiation Effect Research Foundation in the period 1950-1985 based on the recently revised dosimetry, termed the DS86 doses. Mortality from malignant tumors is increased among A-bomb survivors as a late effect of A-bomb radiation. Besides the well-known increase of leukemia, there also has been demonstrated increase of cancer of the lung, breast, esophagus, stomach, colon, ovary, urinary bladder, thyroid, and of multiple myeloma, but no increase has yet been observed in mortality from cancer of the rectum, gallbladder, pancreas, prostate and uterus, and of malignant lymphoma. The pattern of appearance over time of radiation-induced cancer other than leukemia differs from that of leukemia. In general, radiation-induced solid cancer begins to appear after attaining the age at which the cancer is normally prone to develop (so-called cancer age), and continues to increase proportionately with the increase in mortality of the control group as it ages. Sensitivity to radiation, in terms of cancer induction, is higher for persons who were young at the time of the bomb (ATB) in general than for those who were older ATB. Furthermore, susceptibility to radiation-induced cancer tends to be higher in pre- than in post-natally exposed survivors (at least those exposed as adults). Other radiation effect modifiers and the shape of the dose response curve will also be discussed. PMID:1823367

  16. Hyperparathyroidism among A-bomb survivors

    One thousand and thirty men and 2229 women, including A-bomb survivors, have underwent serum routine examinations from August 1986 through December 1987 at Radiation Effects Research Foundation. Hyperparathyroidism was detected in 3 men and 12 women. On the basis of the DS86 system, this cohort was divided into four groups, with the purpose of examining the relationship between atomic bombing and hyperparathyroidism. There were significant differences between exposure doses and the incidence of hyperparathyroidism (0.3% in the 0-9 mGy group vs 1.7% in the ≥1000 mGy group for women; 0.4% in the 10-499 mGy group vs 1.1% in the ≥1000 mGy group for men). Higher serum levels of calcium were significantly associated with exposure doses in both men and women. A similar tendency was observed when patients with hyperparathyroidism were excluded. Serum levels of phosphorus did not show any significant correlation with the bombing, although these were slightly lower in the ≥1000 mGy group. (N.K)

  17. New dosimetry of atomic bomb radiations.

    Fry, R J; Sinclair, W K

    1987-10-10

    The reassessment of the radiation dosimetry from the Hiroshima and Nagasaki atomic bombs is almost complete. Since atomic bomb survivors provide a major source of data for estimates of risk of cancer induction by radiation the impact of the new dosimetry on risk estimates and radiation protection standards is important. The changes include an increase of about 20% in the estimated yield of the Hiroshima bomb and a reduction in the estimated doses from neutrons in both cities. The estimated neutron dose for Hiroshima is about 10% of the previous estimate. The neutron doses are now so small that direct estimates of neutron relative biological effectiveness may be precluded or be much more difficult. There is little change in most of the gamma ray organ doses because various changes in the new estimates tend to cancel each other out. The new estimate of the attenuation of the free-in-air kerma by the walls of the homes is about twice that used in the previous dosimetry. But the transmission of gamma radiation to the deep organs such as bone marrow is significantly greater than earlier estimates. Probably future risk estimates for radiogenic cancer will be somewhat higher because of both the new dosimetry and the new cancer mortality data. New risk estimates should be available in 1988.

  18. Breast cancer among atomic bomb survivors

    Three hundred and sixty cases of breast cancer were collected from among the 63,000 female members of the RERF extended Life Span Study sample which includes atomic bomb exposed women and controls of Hiroshima and Nagasaki. The relationship of these breast cancer cases to A-bomb radiation was sought, and in studying 5-year survival, the following conclusions were obtained concerning its relationship to histopathological findings: 1) The prognosis of the 50+ rad high dose group is the best, followed by the nonexposed group and the low dose group; 2) The apparently better survival may be due, at least in part, to the fact that this group is heavily weighted in favor of those who were younger at the time of the bomb; 3) There is no specificity of the histologic type of breast cancer in the survivors by dose; 4) Nor, is any significant difference observed in the distribution of tumor size and histological grade; 5) Cellular reaction is significantly marked at the stroma of carcinoma tissue in the high dose group; 6) Immune reaction is considered to be strong at the affected site of breast cancer in the high dose group and this can be regarded as a finding suggestive of good prognosis; 7) Further extended studies are therefore warranted.

    2003-01-01

    The construction of muon drift tube chambers (DT) has been carried out in four different european institutes: Aachen (Germany), CIEMAT-Madrid (Spain), Legnaro and Turin (Italy), all of them following similar procedures and quality tests. Each chamber is composed by three or two independent units called superlayers, with four layers of staggered drift cells each. The assembly of a superlayer is a succesive glueing of aluminium plates and I-beams with electrodes previously attached, forming a rectangular and gas-tight volume. These pictures illustrate the various processes of material preparation, construction, equipment and assembly of full chambers at CIEMAT (Madrid).

  1. Space Geodesy and the New Madrid Seismic Zone

    Smalley, Robert; Ellis, Michael A.

    2008-07-01

    One of the most contentious issues related to earthquake hazards in the United States centers on the midcontinent and the origin, magnitudes, and likely recurrence intervals of the 1811-1812 New Madrid earthquakes that occurred there. The stakeholder groups in the debate (local and state governments, reinsurance companies, American businesses, and the scientific community) are similar to the stakeholder groups in regions more famous for large earthquakes. However, debate about New Madrid seismic hazard has been fiercer because of the lack of two fundamental components of seismic hazard estimation: an explanatory model for large, midplate earthquakes; and sufficient or sufficiently precise data about the causes, effects, and histories of such earthquakes.

  5. Influence on social life of atomic bomb, chapter 3

    Atomic bombs, for the first time in human history, were dropped on Hiroshima in August 6, and on Nagasaki on August 9, 1945. Though the powers of these bombs were far small as compared with those of present day nuclear weapons, the atomic bombs claimed many lives instantaneously, damaged human bodies, and destroyed all objects, annihilating the urban areas. Even today, the dreadful consequences of the bombings still remain in both body and mind of the victims. Meanwhile, the experiences of atomic bomb disasters are fading constantly. In order to maintain the vivid information, in Part 3 ''Influence on social life'', the following matters are described: relations of the atomic bombings to society; destroyed societies such as disruption of regional societies and loss of wealth; life of the sufferers such as occupation, marriage, hardships of life, orphans, livelihood variation, and suffering of foreigners; and mental process of the sufferers. (J.P.N.)

  6. Why the USA dropped atomic bombs on Japanese cities

    Why did the USA use atomic bombs on Japanese cities? Because, by summer 1945, the earlier morality that said you should not kill non-combatants had been chipped away, then eroded, and ultimately destroyed by World War II. After Hitler's viciousness, after the Japanese rape of Nanjing, after the killings in Manila, after the savagery through Asia, after Dresden, after Hamburg, after Tokyo, Osaka, Kobe, Nagoya - over sixty Japanese cities had been bombed before Hiroshima, Hiroshima was inevitable, easy, comfortable, virtually automatic. The transformation was not the use of bomb, but the bombing of non-combatants - massively, intentionally. There was probably a desire to revenge, as well. In addition, there was an expectation that the bombs used on japan would also intimidate the Soviet Union but that was not crucial. Any nation that had the capacity would have used the bomb in righteousness and comfort, self-conceived dignity, amid popular applause from its electorate people

    2009-06-01

    Full Text Available The extensive nuclear bomb testing of the fifties and sixties and the final tests in the seventies caused a strong 36Cl peak that has been observed in ice cores world-wide. The measured 36Cl deposition fluxes in eight ice cores (Dye3, Fiescherhorn, Grenzgletscher, Guliya, Huascarán, North GRIP, Inylchek (Tien Shan and Berkner Island were compared with an ECHAM5-HAM general circulation model simulation (1952–1972. We find a good agreement between the measured and the modeled 36Cl fluxes assuming that the bomb test produced global 36Cl input was ~80 kg. The model simulation indicates that the fallout of the bomb test produced 36Cl is largest in the subtropics and mid-latitudes due to the strong stratosphere-troposphere exchange. In Greenland the 36Cl bomb signal is quite large due to the relatively high precipitation rate. In Antarctica the 36Cl bomb peak is small but is visible even in the driest areas. The model suggests that the large bomb tests in the Northern Hemisphere are visible around the globe but the later (end of sixties and early seventies smaller tests in the Southern Hemisphere are much less visible in the Northern Hemisphere. The question of how rapidly and to what extent the bomb produced 36Cl is mixed between the hemispheres depends on the season of the bomb test. The model results give an estimate of the amplitude of the bomb peak around the globe.

  11. Predetonation probability of a fission-bomb core

    Reed, B. Cameron

    2010-08-01

    An undergraduate-level derivation of the probability that a uranium or plutonium fission bomb will suffer an uncontrolled predetonation due to neutrons liberated in spontaneous fissions in the fissile material is developed. Consistent with what was learned by Los Alamos bomb designers during World War II, it is shown why uncontrolled predetonation was not a problem for a U-235 bomb of the Little Boy "gun" design but necessitated development of implosion engineering for the Pu-239 Trinity and Fat Man bombs where the cores were contaminated with highly spontaneously fissile Pu-240.

  13. Low Frequency (11 mHz) Oscillations in H1743-322: A New Class of Black Hole QPOs?

    Altamirano, D.; Strohmayer, T.

    2012-01-01

    We report the discovery of quasi-periodic oscillations (QPO) at approx 11 mHz in two RXTE observations and one Chandra observation of the black hole candidate HI743-322. The QPO is observed only at the beginning of the 2010 and 2011 outbursts at similar hard color and intensity, suggestive of an accretion state dependence for the QPO. Although its frequency appears to be correlated with Xray intensity on timescales of a day, in successive outbursts eight months apart we measure a QPO frequency that differs by less than approximately equals 0.0015 Hz while the intensity had changed significantly. We show that this 11 mHz QPO is different from the so-called Type-C QPOs seen in black holes and that the mechanisms that produce the two flavors of variability are most probably independent. We compare the 11 mHz QPO with other variability phenomena seen in accreting black holes and neutron stars and conclude that although at 1-2 orders of magnitude lower in frequency, they best resemble the so-called "1 Hz" QPOs seen in dipping neutron star systems. If confirmed, H1743-322 is the first black hole showing this type of variability. Given the unusual characteristics and the hard-state dependence of the 11 mHz QPO, we speculate that these oscillations might instead be related to the radio jets observed in HI743-322. It remains unexplained, however, why similar QPOs have not yet been identified in other black holes and why they have only been seen in the last two outbursts of HI743-322.

    The atomic bomb survivors life-span study (LSS) is often claimed to support the linear no-threshold hypothesis (LNTH) of radiation carcinogenesis. This paper shows that this claim is baseless. The LSS data are equally or better described by an s-shaped dependence on radiation exposure with a threshold of about 0.3 Sievert (Sv) and saturation level at about 1.5 Sv. A Monte-Carlo simulation of possible LSS outcomes demonstrates that, given the weak statistical power, LSS cannot provide support ...

    Full Text Available This is an analysis of a glass wall realized in a sports centre in Madrid, in which sport takes place above ground level, in a building of five storeys. The façade of one storey is designed to be totally transparent, so that the building from the outside gives the impression of being «in sections». The window-wall, with a surface area of approximately 47.11 m by 20.24 m, Is achieved by using large sheets of laminated glass, approximately 2.20 m by 3.00 m, tield in place by six suction devices in a metal frame suspended without other support from the roof. From the exterior this material appears with no visible carpentry, with open joints which act as drainage channels. With recent developments in building and technology we can consider using wall materials adaptable to all external conditions, and which allow more possibilities than traditional construction materials. This is especially important for public amenity buildings which, like this one, must present an original and stimulating image, at times, as in this case, displaying to the outside word the activity within.

  18. CALCULATION OF PER PARCEL PROBABILITY FOR DUD BOMBS IN GERMANY

    S. M. Tavakkoli Sabour

    2014-10-01

    Full Text Available Unexploded aerial Bombs, also known as duds or unfused bombs, of the bombardments in the past wars remain explosive for decades after the war under the earth’s surface threatening the civil activities especially if dredging works are involved. Interpretation of the aerial photos taken shortly after bombardments has been proven to be useful for finding the duds. Unfortunately, the reliability of this method is limited by some factors. The chance of finding a dud on an aerial photo depends strongly on the photography system, the size of the bomb and the landcover. On the other hand, exploded bombs are considerably better detectable on aerial photos and confidently represent the extent and density of a bombardment. Considering an empirical quota of unfused bombs, the expected number of duds can be calculated by the number of exploded bombs. This can help to have a better calculation of cost-risk ratio and to classify the areas for clearance. This article is about a method for calculation of a per parcel probability of dud bombs according to the distribution and density of exploded bombs. No similar work has been reported in this field by other authors.

  19. Effects of the atomic bomb: Hiroshima and Nagasaki

    The atomic bomb was aimed at the heart of the multifunctional regional center in he Hiroshima Bay. The buildings were reduced to rubble and ashes by a combination of the blast wave and heat rays. Determining the number of persons exposed to the atomic bomb and those killed is most difficult due to many movements of the people at that time and due to loss of records in the bombing, but from various sources the total physically present population in Hiroshima on the bombing day is estimated to 340,000-350,000. Body injuries resulting from the atomic bombing included burns, trauma and serious body injuries due to radiation. Compared to Hiroshima, blast damage to buildings was more severe in Nagasaki, damage by fire defied all imagination. Population in Nagasaki is estimated at 240,000 on the dy of bombing. Body injuries from exposure to the atomic bombs in Hiroshima and Nagasaki were classified as acute A-bomb injuries in the initial stage, secondary injuries, after-effects, and delayed effects. The Hiroshima and Nagasaki experience is the starting point for projecting and absolute necessity for preventing, the irreversible devastation that would result from the use of current nuclear weapons

  20. Quality improvement program for the B83 bomb hand truck

    1998-04-01

    This report describes the problems, issues, and history of the H1347 bomb hand truck for the B83 bomb after the bomb was put into stockpile in the mid-1980s. Major issues that were reported in Unsatisfactory Reports (URs) were cracking problems on stacking fixture welds, cracked welds on the caster bracket receptacles on the cradle, cracked caster mounting brackets, casters unlocking from the swivel lock position, and caster tires rubbing and binding on the stacking frame. Resolution of these and other problems is described. The introduction of the H695B storage-only bomb hand truck to alleviate a shortage of bomb hand trucks in the mid-1990s is described. The development and qualification of the H1347A bomb hand truck as a replacement for the H695 B is covered. The results from load test evaluations on the stacking fixture, cradle, and casters for the H1347 are described along with towing results on one and two-high stack configurations of B83 bombs in bomb hand trucks. New towing and truck/trailer transport procedures are described. Development, evaluation, and production recommendations for a stronger caster mounting bracket are described.

    Ellerman bombs are transient brightenings of the wings of the Balmer lines that uniquely mark reconnection in the solar photosphere. They are also bright in strong Ca II and ultraviolet lines and in ultraviolet continua, but they are not visible in the optical continuum and the Na I D and Mg I b lines. These discordant visibilities invalidate all published Ellerman bomb modeling. I argue that the assumption of Saha-Boltzmann lower-level populations is informative to estimate bomb-onset opacities for these diverse diagnostics, even and especially for H-alpha, and employ such estimates to gauge the visibilities of Ellerman bomb onsets in all of them. They constrain Ellerman bomb formation to temperatures 10,000 - 20,000 K and hydrogen densities around 10^15 cm^-3. Similar arguments likely hold for H-alpha visibility in other transient phenomena with hot and dense onsets.

  4. Radiation injuries in atomic bomb survivors, chapter 2

    Atomic bombs, for the first time in human history, were dropped on Hiroshima in August 6, and on Nagasaki on August 9, 1945. Though the powers of these bombs were small as compared with those of present day nuclear weapons, the atomic bombs claimed many lives instantaneously, damaged human bodies, and destroyed all objects, annihilating the urban areas. Even today, the dreadful consequences of the bombings still remain in both body and mind of the victims. Meanwhile, the experiences of atomic bomb disasters are fading constantly. In order to maintain the vivid information, in Part 2 ''Bodily injuries'', the following matters are described: early bodily injuries such as burns, (blast) external wounds, radiation injuries, and pathology in bodily injuries; later bodily injuries such as keloids, injuries to blood and eyes, injuries in exposed women, injuries in growth, aging and life, injuries in mental/nervous system, malignant tumors, and changes in chromosomes; and genetic effects. (J.P.N.)

  5. Estimation of neutron doses in Hiroshima and Nagasaki atomic bombings

    For the radiation doses in the Hiroshima and the Nagasaki atomic bombings, the estimated values of T65D (in the United States) have been used. In recent years, however, these values are being restudied. On the basis of the neutron spectra from atomic bombings published from LANL in 1976, the neutron doses in the Hiroshima and Nagasaki atomic bombings were estimated. It was pointed out that the neutron doses of T65D were overestimated. The results of calculation in this estimation were that at the distance from 1 km to 2 km, the neutron doses in Hiroshima and Nagasaki were from 1/5 to 1/9 and about 1/3, respectively, as compared with those in T65D. The estimation of the neutron doses in the atomic bombings by calculation, the difference from T65D and the comparison with the measured radioactivities immediately after atomic bombings are described.

  6. Microstructural characterization of pipe bomb fragments

    Recovered pipe bomb fragments, exploded under controlled conditions, have been characterized using scanning electron microscopy, optical microscopy and microhardness. Specifically, this paper examines the microstructural changes in plain carbon-steel fragments collected after the controlled explosion of galvanized, schedule 40, continuously welded, steel pipes filled with various smokeless powders. A number of microstructural changes were observed in the recovered pipe fragments: deformation of the soft alpha-ferrite grains, deformation of pearlite colonies, twin formation, bands of distorted pearlite colonies, slip bands, and cross-slip bands. These microstructural changes were correlated with the relative energy of the smokeless powder fillers. The energy of the smokeless powder was reflected in a reduction in thickness of the pipe fragments (due to plastic strain prior to fracture) and an increase in microhardness. Moreover, within fragments from a single pipe, there was a radial variation in microhardness, with the microhardness at the outer wall being greater than that at the inner wall. These findings were consistent with the premise that, with the high energy fillers, extensive plastic deformation and wall thinning occurred prior to pipe fracture. Ultimately, the information collected from this investigation will be used to develop a database, where the fragment microstructure and microhardness will be correlated with type of explosive filler and bomb design. Some analyses, specifically wall thinning and microhardness, may aid in field characterization of explosive devices.

  7. The genetic effects of the atomic bombs

    Studies on the genetic effects of the atomic bombs detonated over Hiroshima and Nagasaki have been in progress since 1946. The indicators of potential genetic damage in the children of exposees which have been employed are: (1) untoward pregnancy outcomes (major congenital defect and/or stillbirth and/or neonatal death), (2) death of liveborn infants prior to average age 28.8 years, (3) cancer of onset prior to age 20, (4) sex chromosome aneuploidy, (5) mutations affecting protein electrophoretic mobility and/or activity, (6) chromosomal reciprocal translocations, (7) sex-ratio in the children of exposed mothers, and (8) physical development at birth, at 9-months, and at school age. There is no statistically significant effect of parental exposure to the bombs on any of these indicators. The net regression of indicator(s) on dose is, however, positive. On the basis of these regressions and assumptions concerning the contribution of spontaneous mutation to the indicator values in the controls, the gametic doubling dose of acute ionizing radiation under these circumstances is estimated to be 2 Sv. With a dose rate factor of 2, which seems appropriate to these circumstances, the doubling dose for chronic radiation is placed at 4 Sv. This is a substantially higher estimate than previous extrapolations to man from murine experiments

  8. A-bomb and skin injury

    Injury and influence in the skin given by A-bomb are reviewed from the dermatological aspect. As an acute injury, primary and secondary thermal burns, flash and flame, respectively, are generally caused by high-energy heat. More than 90% people present within 1 km diameter area of the hypocenter died in a week and about 30% of whom did due to burns. Alopecia appeared in those who had been exposed to A-bomb radiation within 2.5 km diameter region of the hypocenter in Hiroshima and Nagasaki, and purpura, an important measure of radiation injury, occurred maximally 20-30 days after explosion in most of those people above. Late injury involves keloid and malignant skin tumor. The former, hypertrophic scar, was seen mainly in the curing process of the burns in 60-80% and was of somewhat different morphology after flash and flame injuries. In 1987, the correlation between the incidence of skin cancer and exposed dose was recognized in 20,348 survivors in Nagasaki. In the period from 1958 to 1987, the incidence of basal cell carcinoma was found increased in the comparative studies of about 90,000 people consisting of survivors and non-exposed control. Skin examination is pointed out from the aspect to be important in those people exposed to the higher radiation dose than general population, like workers in the nuclear power plant and medical field as well as in those enrolled in a nuclear accident.

  9. Impact on the Japanese atomic bomb survivors of radiation received from the bombs.

    Cullings, Harry M

    2014-02-01

    The Radiation Effects Research Foundation (RERF) studies various cohorts of Japanese atomic bomb survivors, the largest being the Life Span Study (LSS), which includes 93,741 persons who were in Hiroshima or Nagasaki at the times of the bombings; there are also cohorts of persons who were exposed in utero and survivors' children. This presentation attempts to summarize the total impact of the radiation from the bombs on the survivors from both an individual perspective (both age-specific and integrated lifetime risk, along with a measure of life expectancy that describes how the risk affects the individual given age at exposure) and a group perspective (estimated numbers of excess occurrences in the cohort), including both early and late effects. As survivors' doses ranged well into the acutely lethal range at closer distances, some of them experienced acute signs and symptoms of radiation exposure in addition to being at risk of late effects. Although cancer has always been a primary concern among late effects, estimated numbers of excess cancers and hematopoietic malignancies in the LSS are a small fraction of the total due to the highly skewed dose distribution, with most survivors receiving small doses. For example, in the latest report on cancer incidence, 853 of 17,448 incident solid cancers were estimated to be attributable to radiation from the bombs. RERF research indicates that risk of radiation-associated cancer varies among sites and that some benign tumors such as uterine myoma are also associated with radiation. Noncancer late effects appear to be in excess in proportion to radiation dose but with an excess relative risk about one-third that of solid cancer and a correspondingly small overall fraction of cases attributable to radiation. Specific risks were found for some subcategories, particularly circulatory disease, including stroke and precedent conditions such as hypertension. Radiation-related cataract in the atomic bomb survivors is well known

    2010-01-01

    Interchanges are key elements for improving seamless mobility in metropolitan areas where multi-stages trips are increasing. Interchange facilities make transfers short, easy and comfortable, and therefore Public Transport (PT) trips became more attractive and competitive. However, good quality interchanges are rather expensive, especially with regard to construction and operation. The solution launched in Madrid was a public–private scheme where all stakeholders involved play a key role. The...

  17. Foreign bodies radiographically-demonstrated in atomic bomb survivors

    Tamura, S.; Onitsuka, H.; Lee, K.; Shimizu, Y.; Russell, W.J.

    1978-08-25

    The prevalence of roentgenologically-detected foreign bodies among atomic bomb (A-bomb) survivors was studied as an indicator of the A-bomb blast effects. Acupuncture was studied as an indicator of A-bomb-related abnormalities for which it was administered. All Adult Health Study subjects' roentgenograms demonstrating foreign bodies were reviewed. The frequency of glass and metal, and acupuncture needles were analyzed by distance from hypocenters, sex, age, body sites involved; and the subjects' shielding at the times of the A-bombs. The presence of glass fragments correlated closely with distance from hypocenter, heavy shielding from the A-bombs, and with adulthood, and they were more frequent in the chest than hand and wrist. Metal foreign bodies were more frequent in the hand and wrist than in the chest, and not associated with distance from hypocenter or heavy shielding. The prevalence of acupuncture needles increased with age, but did not correlate with A-bomb dose.

  18. Chain reaction. History of the atomic bomb

    Henri becquerel tracked down in 1896 a strange radiation, which was called radioactivity by Marie Curie. In the following centuries German scientists Max Planck, Albert Einstein and Werner Heisenberg presented fundamental contributions to understand processes in the atomic nucleus. At Goettingen, center of the international nuclear physics community, the American student J. Robert Oppenheimer admit to this physical research. In the beginning of 1939 the message of Otto Hahns' nuclear fission electrified researchers. The first step, unleashing atomic energy, was done. A half year later the Second World War begun. And suddenly being friend with and busily communicating physicians were devided into hostile power blocs as bearers of official secrets. The author tells in this exciting book the story of the first atomic bomb as a chain reaction of ideas, discoveries and visions, of friendships, jealousy and intrigues of scientists, adventurers and genius.

  19. Dirty bombs: assesment of radiological impacts

    In some countries, regulatory control of radioactive sources, used extensively in medicine and industry, remains weak. Global concerns about the security and safety of radioactive sources escalated following the September 11 2001 terrorist attacks in the United States. There are fears that some radioactive sources could be used by terrorists as radiological dispersal devices (RDD's), or so called 'dirty bombs'. The radioactive material dispersed, depending on the amount and intensity, could cause radiation sickness for a limited number of people nearby if, for example, they inhaled large amounts of radioactive dust. But the most severe tangible impacts would likely be the economic costs and social disruption associated with the evacuation and subsequent clean-up of contaminated property. It has been shown that usage of realistic data in a first response decision making as to avoid inappropriate public reaction accompanied by economic and social consequences is necessary.(author)

  20. Radioepidemiology of the A-bomb survivors.

    Schull, W J

    1996-06-01

    Estimation of the risk of cancer and other health effects following exposure to the atomic bombing of Hiroshima and Nagasaki remains largely empirical, and the models used to adduce risk incorporate few, if any, of the advances in molecular biology of the past decade or so. These facts compromise the estimation of risk where the epidemiologic data are weakest, namely, at low doses and dose rates. Although the risk estimates may be sufficient for regulatory purposes, without a better understanding of the molecular and cellular events ionizing radiation initiates or promotes, it seems unlikely that the estimates will be as intellectually satisfying as they might be. Nor will the situation improve further without attention to the identification and estimation of the effects of those host and environmental factors that enhance or diminish risk of cancer or the effects on the developing brain.

  1. Jets and Bombs: Characterizing IRIS Spectra

    Schmit, Donald; Innes, Davina

    2014-06-01

    For almost two decades, SUMER has provided an unique perspective on explosive events in the lower solar atmosphere. One of the hallmark observations during this tenure is the identification of quiet sun bi-directional jets in the lower transition region. We investigate these events through two distinct avenues of study: a MHD model for reconnection and the new datasets of the Interface Region Imaging Spectrograph (IRIS). Based on forward modeling optically thin spectral profiles, we find the spectral signatures of reconnection can vary dramatically based on viewing angle and altitude. We look to the IRIS data to provide a more complete context of the chromospheric and coronal environment during these dynamic events. During a joint IRIS-SUMER observing campaign, we observed spectra of multiple jets, a small C flare, and an Ellerman bomb event. We discuss the questions that arise from the inspection of these new data.

  2. Aging studies in atomic bomb survivors

    Although the studies of the effect of ionizing radiation on atomic bomb survivors have not produced any evidence of radiation-induced aging, there have been studies on experimental animals and man which suggest accelerated aging after exposure to ionizing radiation. To determine if certain physiologic functions could be related to exposure to ionizing radiation, a battery of age-related tests was given at the time of the physical examinations at ABCC. Some 11,351 persons were given these non-invasive age-related tests. The results were essentially negative. Until a satisfactory operational definition of biologic or physiologic age is developed, the administration of functional tests as a measure of aging does not seem justified. (author)

  3. Eye damage following neutron bomb explosion

    A brief review is presented of primary and secondary eye damage due to neutron and/or gamma radiation following the explosion of a neutron bomb. Of early radiation damage of the eye, flash blindness is the most serious effect. Most other early changes can only be expected following doses of at least 1 - 5 Gy. They are therefore worth considering only in cases of irradiation of the head alone since at these doses death of the individual due to damage of other vital systems occurs before the eye symptoms have time to develop. Of delayed effects, the development of radiation cataract, radiodermatitis developing in tumors, the dry eye syndrome, and other changes leading to the development of radiation syndrome can be expected which result in the reduction in the quality of life and may lead to death due to systemic disease.

  4. Multiwavelength spectropolarimetric observations of an Ellerman bomb

    Rezaei, R.; Beck, C.

    2015-10-01

    Context. Ellerman bombs (EBs) are enhanced emission in the wings of the Hα line in the solar spectrum. Aims: We study the structure of an EB in the photosphere and chromosphere. Methods: We analyze simultaneous observations of four chromospheric lines (Hα, Ca ii H, Ca ii IR 854 nm, and He i 1083 nm) as well as two photospheric lines (Fe i 630 and Si i 1082.7 nm) along with high-cadence 160 and 170 nm ultraviolet (UV) continuum filtergrams. Full Stokes data from the Helioseismic and Magnetic Imager (HMI) are used to trace the temporal evolution of the magnetic structure. Results: We identify the EB by excess emission in the wings of the Hα line, a brightening in the UV continuum, and large emission peaks in the core of the two Ca ii lines. The EB shows a blueshift in all chromospheric lines, while no shifts are observed in the photospheric lines. The blueshift in the chromospheric layer causes very asymmetric emission peaks in the Ca ii H line. The photospheric Si i spectral line shows a shallower line depth at the location of the EB. The UV continuum maps show that the EB was substantially brighter than its surroundings for about 30 min. The continuum contrast of the EB from 170 nm to 1080 nm shows a power-law dependency on the wavelength. The temperature enhancement amounts to 130 K in the low photosphere and 400 K at the temperature minimum level. This temperature excess is also seen in an LTE inversion of the Ca ii spectra. The total thermal and radiative energy content of the EB is about 1020 J and 1018 J in the photosphere and chromosphere, respectively. The HMI data hints at a photospheric magnetic flux cancellation as the driver of the EB. Conclusions: Ellerman bombs release the energy in a height range of several pressure scale heights around the temperature minimum such that they affect both the photosphere and the lower chromosphere.

    Residential areas of detached houses were built in north and east Madrid, Spain, during the last decade of the 20th century. Because the popula- tion density in those areas is low, implementing an efficient transport system is complicated. In south Madrid in the 1960s, however, huge commuter towns developed. Some of them were linked to a suburban network at some point, whereas others were far away. The Madrid region promoted the construction of several light rail lines to resolve this issue. ...

  7. Comparison of road traffic emission models in Madrid (Spain)

    Borge, Rafael; de Miguel, Isabel; de la Paz, David; Lumbreras, Julio; Pérez, Javier; Rodríguez, Encarnación

    2012-12-01

    Many cities in Europe have difficulties to meet the air quality standards set by the European legislation, most particularly the annual mean Limit Value for NO2. Road transport is often the main source of air pollution in urban areas and therefore, there is an increasing need to estimate current and future traffic emissions as accurately as possible. As a consequence, a number of specific emission models and emission factors databases have been developed recently. They present important methodological differences and may result in largely diverging emission figures and thus may lead to alternative policy recommendations. This study compares two approaches to estimate road traffic emissions in Madrid (Spain): the COmputer Programme to calculate Emissions from Road Transport (COPERT4 v.8.1) and the Handbook Emission Factors for Road Transport (HBEFA v.3.1), representative of the 'average-speed' and 'traffic situation' model types respectively. The input information (e.g. fleet composition, vehicle kilometres travelled, traffic intensity, road type, etc.) was provided by the traffic model developed by the Madrid City Council along with observations from field campaigns. Hourly emissions were computed for nearly 15 000 road segments distributed in 9 management areas covering the Madrid city and surroundings. Total annual NOX emissions predicted by HBEFA were a 21% higher than those of COPERT. The discrepancies for NO2 were lower (13%) since resulting average NO2/NOX ratios are lower for HBEFA. The larger differences are related to diesel vehicle emissions under "stop & go" traffic conditions, very common in distributor/secondary roads of the Madrid metropolitan area.In order to understand the representativeness of these results, the resulting emissions were integrated in an urban scale inventory used to drive mesoscale air quality simulations with the Community Multiscale Air Quality (CMAQ) modelling system (1 km2 resolution). Modelled NO2 concentrations were compared

    Atomic bomb survivors are a population suitable for studying the relationship between somatic mutation and cancer risk because their exposure doses are relatively well known and their dose responses in terms of cancer risk have also been thoroughly studied. An analysis has been made of erythrocyte glycophorin A (GPA) gene mutations in 1,226 atomic bomb survivors in Hiroshima and Nagasaki. The GPA mutation frequency (Mf) increased slightly but significantly with age at the time of measurement ...

    Werner Heisenberg, leader of the Nazi atomic bomb program, revealed the projects existence to Niels Bohr in a meeting in Copenhagen in 1941. But contrary to several historical accounts of the meeting, Heisenberg never expressed moral qualms about building a bomb for Hitler nor hinted that he might be willing to sabotage the project, according to secret documents cited in a London newspaper yesterday (2 pages).

  13. Trash can bomb can fall into the hands of terrorists

    2001-01-01

    Leading scientists from CERN described how if terrorists were able to get their hands on plutonium or uranium, they would be able to manufacture a 'trash can' nuclear bomb simply by inserting the radioactive material into a normal bomb. Once detonated a large area could be contaminated leading to the immediate deaths of many with many more future casualties due to cancers caused by the radiation.

The seed source is an acousto-optic Q-switched fiber laser with a varied pulse duration and repetition rate. The output average power of the oscillator is ∼30 mW and two pre-amplifiers were developed to boost the average power to ∼3 W. Pulse energy of >11 mJ for ∼660 ns pulses at 3 kHz was achieved in the final power amplifier using a commercial 50/400 μm (core/cladding diameter) double cladding Yb-doped fiber (DCYF). (letter)

  16. Biosynthetic Origin of the Antibiotic Pseudopyronines A and B in Pseudomonas putida BW11M1.

    Bauer, Judith S; Ghequire, Maarten G K; Nett, Markus; Josten, Michaele; Sahl, Hans-Georg; De Mot, René; Gross, Harald

    2015-11-01

    Within the framework of our effort to discover new antibiotics from pseudomonads, pseudopyronines A and B were isolated from the plant-derived Pseudomonas putida BW11M1. Pseudopyronines are 3,6-dialkyl-4-hydroxy-2-pyrones and displayed high in vitro activities against several human pathogens, and in our hands also towards the plant pathogen Pseudomonas savastanoi. Here, the biosynthesis of pseudopyronine B was studied by a combination of feeding experiments with isotopically labeled precursors, genomic sequence analysis, and gene deletion experiments. The studies resulted in the deduction of all acetate units and revealed that the biosynthesis of these α-pyrones occurs with a single PpyS-homologous ketosynthase. It fuses, with some substrate flexibility, a 3-oxo-fatty acid and a further unbranched saturated fatty acid, both of medium chain-length and provided by primary metabolism. PMID:26507104

  17. Direct generation of intense extreme ultraviolet supercontinuum with chirped 11-mJ pulses from a femtosecond laser amplifier

    Zeng, Bin; Li, Guihua; Yao, Jinping; Ni, Jielei; Zhang, Haisu; Cheng, Ya; Xu, Zhizhan

    2011-01-01

    We report on the generation of intense extreme ultraviolet (EUV) supercontinuum with photon energies spanning from 35 eV to 50 eV (i. e., supporting an isolated attosecond pulse with a duration of ~271 as) by loosely focusing 11-mJ chirped pulses from a femtosecond laser amplifier into a 10-mm long gas cell filled with krypton gas. We observe that when high-order harmonics are generated with transformed-limited ~35 fs pulses, only discrete harmonics can be produced; whereas for negatively chirped 188 fs pulses, EUV supercontinuum can be observed in single-shot harmonic spectrum. The dramatic change of spectral and temporal properties of the driver pulses after passing through the gas cell indicates that propagation effects play a significant role in promoting the generation of the EUV supercontinuum.

  18. Late Pleistocene and Holocene paleoseismology of an intraplate seismic zone in a large alluvial valley, the New Madrid seismic zone, Central USA

    Guccione, Margaret J.

    2005-10-01

    . Seven fault segments are recognized by microseismicity and geomorphology. Surface faulting has been recognized at three of these segments, Reelfoot fault, New Madrid North fault, and Bootheel fault. The Reelfoot fault is a compressive stepover along the strike-slip fault and has up to 11 m of surface relief ([Carlson, S.D., 2000. Formation and geomorphic history of Reelfoot Lake: insight into the New Madrid seismic zone. M.S. Thesis, University of Arkansas, Fayetteville, Arkansas, U.S.A]) deforming abandoned and active Mississippi River channels ([Guccione, M.J., Mueller, K., Champion, J., Shepherd, S., Odhiambo, B., 2002b. Stream response to repeated co-seismic folding, Tiptonville dome, western Tennessee. Geomorphology 43 (2002), 313 349]). The New Madrid North fault apparently has only strike-slip motion and is recognized by modern microseismicity, geomorphic anomalies, and sand cataclasis ([Baldwin, J.N., Barron A.D., Kelson, K.I., Harris, J.B., Cashman, S., 2002.

  19. Mental health status of A-bomb survivors in Nagasaki

    The most survivors of disaster usually recover with few or no lasting effects on their mental health. However, in some portions of survivors, distress lasts long. The atomic bomb detonated to Nagasaki in August 1945 instantaneously destroyed almost all areas of the city, resulting in a total of ca. 73,884 deaths by the end of 1945 and about 74,909 injured people. Since the A-bomb survivors reached over 60 years of age, their mental health as well as physical health has become of great concern. Some studies on their mental health conditions have been carried out in Japan. I give an outline about a precedent study on mental health of the A-bomb survivors in this report. The mental health studies of the A-bomb survivors who paid attention to a being bombed experience, stigmatization, long-term outcome, recovery are necessary. The improvement of wide appropriate support system for the A-bomb survivors is expected in future. (author)

  20. Long-term follow-up of atomic bomb survivors.

    2012-06-01

    The Life Span Study (LSS) is a follow-up study of atomic bomb (A-bomb) survivors to investigate the radiation effects on human health and has collected data for over 60 years. The LSS cohort consists of 93,741 A-bomb survivors and another 26,580 age and sex-matched subjects who were not in either city at the time of the bombing. Radiation doses have been computed based on individual location and shielding status at the time of the bombings. Age at death and cause of death are gathered through the Japanese national family registry system and cancer incidence data have been collected through the Hiroshima and Nagasaki cancer registries. Noncancer disease incidence and health information are collected through biannual medical examinations among a subset of the LSS. Radiation significantly increases the risks of death (22% at 1 Gy), cancer incidence (47% at 1 Gy), death due to leukemia (310% at 1 Gy), as well as the incidence of several noncancer diseases (e.g. thyroid nodules, chronic liver disease and cirrhosis, uterine myoma, and hypertension). Significant effects on maturity (e.g. growth reduction and early menopause) were also observed. Long-term follow-up studies of the A-bomb survivors have provided reliable information on health risks for the survivors and form the basis for radiation protection standards for workers and the public.

  1. Mental health for elder A-bomb survivors

    A pilot study was made, based on an interview survey, to improve mental hygiene in A-bomb survivors. The study consisted of General Health Questionnaire (GHQ) 12 items, Composite International Diagnostic Interview (CIDI), Social Disabilities Schedule (SDS), and General Health Questionnaire (GHQ) 30 items. A majority of the subjects were those aged in their fifties, sixties, and seventies. Eighty A-bomb survivors answered GHQ 12 items, consisting of 7, 17, and 41 who were exposed at <2.0 km, 2.0-2.9 km, and ≥3.0 km from the hypocenter, respectively, and 15 who entered the city early after A-bombing. Thirty-three A-bomb survivors answered CIDI. According to the distance from the hypocenter, the corresponding figures were 2, 10, 15, and 6 A-bomb survivors. The survey for GHQ 12 items revealed that more A-bomb survivors exposed nearer the hypocenter suffered from mental problems. In the survey for CIDI, the most common complaints were found to be physical expression disorder (n=9) and chronic pain (n=8), followed by hypochondria (n=4), panic disorder (n=2), and anxiery (n=one). According to the SDS survey, 85% were judged as having no mental disorder, and the remaining 15% as having merely mild or moderate disorder. (N.K.)

  2. Foreign bodies radiographically demonstrated in atomic bomb survivors

    1978-02-01

    The prevalence of roentgenologically-detected foregin bodies among atomic bomb survivors was studied as an indicator of the A-bomb blast effects. Acupuncture was studied as an indicator of possible A-bomb-related abnormalities for which it was administered. All available roentgenograms of Adult Health Study (AHS) subjects which demonstrated foreign bodies were reviewed. The frequency of glass and metal foreign bodies and of acupuncture needles was analyzed in detail. Analyses were made by distance from the hypocenter, sex, age, body sites involved, and shielding at the time of the A-bomb (ATB). The presence of glass fragments correlated closely with distance from the hypocenter, with heavy shielding from the A-bombs, and with adulthood, and they were more frequent in the chest than in the hand and wrist. On the contrary, metal foreign bodies were more frequent in the hand and wrist than in the chest, and were not associated with distance from hypocenter or heavy shielding. The prevalence of acupuncture needles increased with age, but did not correlate with A-bomb dose.

  3. Association of Acute Radiation Syndrome and Rain after the Bombings in Atomic Bomb Survivors.

    Ozasa, K; Sakata, R; Cullings, H M; Grant, E J

    2016-06-01

    Acute radiation-induced symptoms reported in survivors after the atomic bombings in Hiroshima and Nagasaki have been suspected to be associated with rain that fell after the explosions, but this association has not been evaluated in an epidemiological study that considers the effects of the direct dose from the atomic bombs and other factors. The aim of this study was to evaluate this association using information from a fixed cohort, comprised of 93,741 members of the Life Span Study who were in the city at the time of the bombing. Information on acute symptoms and exposure to rain was collected in surveys conducted by interviewers, primarily in the 1950s. The proportion of survivors developing severe epilation was around 60% at levels of direct radiation doses of 3 Gy or higher and less than 0.2% at levels <0.005 Gy regardless of reported rain exposure status. The low prevalence of acute symptoms at low direct doses indicates that the reported fallout rain was not homogeneously radioactive at a level sufficient to cause a substantial probability of acute symptoms. We observed that the proportion of reported acute symptoms was slightly higher among those who reported rain exposure in some subgroups, however, suggestions that rain was the cause of these reported symptoms are not supported by analyses specific to the known areas of radioactive fallout. Misclassification of exposure and outcome, including symptoms due to other causes and recall bias, appears to be a more plausible explanation. However, the insufficient and retrospective nature of the available data limited our ability to quantify the attribution to those possible causes. PMID:27223827

  4. Chromosomal aberrations in peripheral lymphocytes from A-bomb survivors who entered the city early after A-bombing

    It has been thought that A-bomb survivors who entered the city early after A-bombing were exposed to residual A-bomb radiation both externally and internally (through inhalation, food, drink or skin). This paper summarizes the data on estimated radiation doses in A-bomb survivors who entered Hiroshima within 3 days after A-bombing based on the chromosome staining analysis of lymphocytes of peripheral blood taken from A-bomb survivors. The subjects were 40 A-bomb survivors; according to a stay period and a history of medical irradiation, they were divided into four: group A with a long stay, group B with a long stay + medical irradiation, group C with a short stay, and group D with a short stay + medical irradiation. A mean estimated radiation dose was 4.8 rad (one rad or less to 13.5 rad) in group A, 13.9 rad (one rad or less to 71.2 rad) in group B, one rad or less in group C, and 1.9 rad (one rad or less to 21.2 rad) in group D. The highest rate of chromosomal aberrations was 3.1% in group B, followed by 2.1% in group A, 0.83% in group D, and 0.73% in group C. The frequency of chromosomal aberrations was coincident with the duration of stay in the city. Furthermore, medical irradiation seemed to have contributed to the additional effects of A-bomb radiation. (N.K.)

  12. Cancer developing among atom-bomb survivors

    Cancer (with the exception of leukemia) which had often been observed among atom bomb survivors was discussed. Prevalence of thyroid carcinoma was high in the people who had been exposed to more than 50 rad of the atomic radiation. A great difference in prevalence of cancer was seen between irradiated people whose age had been under 20 years at the time of exposure and non-irradiated. More women than men had papillary adenocarcinoma. The highest prevalence was seen 16 to 20 years after exposure to atomic radiation, but there was no difference in prevalence between those from Hiroshima and from Nagasaki. Lung cancer comprised 89% of all cancers of the people whose age was 50 years and over. Most of them had been exposed to atomic radiation of more than 300 rad. The type was cellular retrograde cancer. The prevalence of gastric carcinoma was low, and breast cancer occurred at an early age before menopause. The occurrence of cancer in juvenile survivors was several times higher in the patients who had been exposed to atomic radiation of more than 100 rad than in non-irradiated. These values indicate that cancer occurs more frequently than leukemia does in such survivors. (Kanao, N.)

  13. Breast cancer in atomic bomb survivors

    Thirty eight years after the atomic bombings, studies of the Radiation Effects Research Foundation (RERF) on the extended Life Span Study (LSS) sample have continued to provide important information on radiation carcinogenesis. The third breast cancer survey among this sample revealed 564 cases during the period 1950-80, of which 412 were reviewed microscopically. The following statements reflect the conclusions from the current investigation; 1) the relationship between radiation dose and breast cancer incidence was consistent with linearity and did not differ markedly between the Hiroshima and Nagasaki survivors, 2) a dose-related breast cancer risk was observed among women who were in their first decade of life at the time of exposure, 3) the relative risk of radiationinduced breast cancer decreased with increasing age at exposure, 4) the pattern over time of age-specific breast cancer incidence is similar for exposed and control women (that is, exposed women have more breast cancer than control women but the excess risk closely follows normal risk as expressed by age-specific population rates), and 5) radiation-induced breast cancer appears to be morphologically similar to other breast cancer

  14. Simulating an Exploding Fission-Bomb Core

    Reed, Cameron

    2016-03-01

    A time-dependent desktop-computer simulation of the core of an exploding fission bomb (nuclear weapon) has been developed. The simulation models a core comprising a mixture of two isotopes: a fissile one (such as U-235) and an inert one (such as U-238) that captures neutrons and removes them from circulation. The user sets the enrichment percentage and scattering and fission cross-sections of the fissile isotope, the capture cross-section of the inert isotope, the number of neutrons liberated per fission, the number of ``initiator'' neutrons, the radius of the core, and the neutron-reflection efficiency of a surrounding tamper. The simulation, which is predicated on ordinary kinematics, follows the three-dimensional motions and fates of neutrons as they travel through the core. Limitations of time and computer memory render it impossible to model a real-life core, but results of numerous runs clearly demonstrate the existence of a critical mass for a given set of parameters and the dramatic effects of enrichment and tamper efficiency on the growth (or decay) of the neutron population. The logic of the simulation will be described and results of typical runs will be presented and discussed.

    Ellerman Bombs (EBs) are often found to be co-spatial with bipolar photospheric magnetic fields. We use Hα imaging spectroscopy along with Fe i 6302.5 Å spectropolarimetry from the Swedish 1 m Solar Telescope (SST), combined with data from the Solar Dynamic Observatory, to study EBs and the evolution of the local magnetic fields at EB locations. EBs are found via an EB detection and tracking algorithm. Using NICOLE inversions of the spectropolarimetric data, we find that, on average, (3.43 ± 0.49) × 1024 erg of stored magnetic energy disappears from the bipolar region during EB burning. The inversions also show flux cancellation rates of 1014–1015 Mx s‑1 and temperature enhancements of 200 K at the detection footpoints. We investigate the near-simultaneous flaring of EBs due to co-temporal flux emergence from a sunspot, which shows a decrease in transverse velocity when interacting with an existing, stationary area of opposite polarity magnetic flux, resulting in the formation of the EBs. We also show that these EBs can be fueled further by additional, faster moving, negative magnetic flux regions.

  17. Health effects of atomic-bomb radiation

    This review described carcinogenic and genetic effects of A-bomb radiation. Effects have been investigated on 120,000 exposed people for their life span, 20,000 for health examinations, 3,000 people exposed in the womb and 80,000 second-generations of the exposed people. Epidemiological data revealed the presence of carcinogenic effects: Cancer death amounted to 9% from 1950 to 1990. However, carcinogenic mechanism is unknown yet. Genetic effects have been studied from the points of lesion at birth, sex ratio, chromosome aberration, biochemical test and mortality rate of children of exposed people and, although the effects have been experimentally shown in animals, are not observed in those children. This may be derived from the fact that there are few people who were exposed to such a high dose as used experimentally (0.2 Sv exposure to people within 2.5 km diameter-area from the explosion point vs >3 Sv in animals). Data are presented in Research Foundation home page. (K.H.)

  18. Nuclear policies: fuel without the bomb

    The essays, developed from studies conducted by the California seminar on arms control and foreign policy, address technical, political, and economic aspects of nonproliferation. How to halt nuclear proliferation commands worldwide attention today. The search for new energy resources by industrial as well as nonindustral nations has led to the spread of nuclear technology and the production of weapons grade fuel materials such as plutonium and enriched uranium in the name of energy independence. The background and consequences of this growing danger and possible solutions to it are the substance of the essays. Conceding the desirability (if not necessity) of developing nuclear power as an energy source, the writers focus on the different reactor technologies; an historical perspective of proliferation through the example of India; the rationales for stringent international monitoring; and finally, the link between proliferation and the spread of nuclear weapons. The chapters are: Nuclear technology: essential elements for decisionmakers, Robert Gillette; Must we decide now for worldwide commerce in plutonium fuel, Albert Wohlstetter; US peaceful aid and the Indian bomb, Roberta Wohlstetter; International discipline over the uses of nuclear energy, Victor Gilinsky; and Nuclear energy and the proliferation of nuclear weapons, Victor Gilinsky

  19. Atomic bomb survivor data: utilization and analysis

    There were several motivations for organizing the SIMS Conference reported in this monograph. Risk assessment and its methods have been subjects of several SIMS Conferences in the recent past, and focusing these newer, more powerful methods on the largest human experience of exposure to ionizing radiation seemed an appropriate sequel. There was also the conviction that the data resources of the Radiation Effects Research Foundation (RERF), generated through the mortality and medical follow-up of large samples of the survivors of the atomic bombs dropped on Hiroshima and Nagasaki, were being under utilized, and that a conference and its proceedings would create interest in exploiting this resource. The time seemed ripe for gathering a small group of current RERF scientists, veteran US statisticians and epidemiologists, and others with more recent entry into the field of radiation biology to consider long range plans for maximizing the output of information not only on the long term effects of ionizing radiation on man but on new knowledge of the determinants of health and disease that can be learned by study of the records of this cohort. This seemed particularly appropriate at this time while intensive joint Japanese-US efforts are underway to provide a new, more accurate dosimetry for use in these studies. Finally, there was a hope that an ad hoc forum of this type would provide not only a summary of current statistical and epidemiologic activities at RERF, but a useful critique of their scope and quality

  20. Uranium content in soil after bombing FRY

    Depleted uranium (DU) is a byproduct of uranium enrichment process and its use is very dangerous and harmful. NATO has used DU ammunition in Yugoslav conflict during its air campaign against the tanks and bunkers. The estimated number of about 3,000-10,000 of 30 mm DU rounds as armor-piercing shells were fired from cannons fitted to A-10 aircraft and probably a usage in some of 1,500 launched Tomahawk Cruise missiles. We measured uranium content in the surface soil (0-5 cm depth) from bomb craters during NATO attack. Selected locations were Belgrade, Smederevo, Nis, Bor, Prahovo, Kadinjaca, Jadovnik, Raska, Sjenica, and Cape Arza. Total uranium concentration and isotopic ratio were determined using γ-spectrometry and inductively coupled plasma method. Obtained results were in the range 21 - 762.000 Bq/kg dry soil. They were at the all locations except Cape Arza comparable to the uranium content found in off-side locations of soils. (author)

  1. Atomic Bomb Survivors Life-Span Study

    Dobrzyński, Ludwik

    2015-01-01

    The atomic bomb survivors life-span study (LSS) is often claimed to support the linear no-threshold hypothesis (LNTH) of radiation carcinogenesis. This paper shows that this claim is baseless. The LSS data are equally or better described by an s-shaped dependence on radiation exposure with a threshold of about 0.3 Sievert (Sv) and saturation level at about 1.5 Sv. A Monte-Carlo simulation of possible LSS outcomes demonstrates that, given the weak statistical power, LSS cannot provide support for LNTH. Even if the LNTH is used at low dose and dose rates, its estimation of excess cancer mortality should be communicated as 2.5% per Sv, i.e., an increase of cancer mortality from about 20% spontaneous mortality to about 22.5% per Sv, which is about half of the usually cited value. The impact of the “neutron discrepancy problem” – the apparent difference between the calculated and measured values of neutron flux in Hiroshima – was studied and found to be marginal. Major revision of the radiation risk assessment paradigm is required. PMID:26673526

  2. Dirty Bombs: A Discouraging Second Look

    Loeb, Cheryl A.

    2004-05-01

    Dirty bombs, terrorist devices to spread intensely radioactive material with the intent to kill, sicken, or inflict economic damage, have been overestimated by some in the government and underestimated by many physicists. It is unlikely that a radiological dispersion device (RDD) will contaminate an area to such a level that brief exposures are lethal or even incapacitating. However, careful examination of the consequences of the accident in Goiânia, Brazil shows that it is highly likely that people in the contaminated region will inhale or ingest dusty or liquid radioactive material in sufficient quantities to cause acute radiation sickness, and in some cases enough to kill. Some forms of radiological attack could kill tens or hundreds of people and sicken hundreds or thousands. This paper provides a general overview of the nature and use of RDDs and examines readily available sources of large quantities of radioactive material, material which requires significantly greater protection than it is afforded today. Under many circumstances an RDD containing only a few curies of cesium-137, strontium-90, cobalt-60 or other industrial isotopes could force the razing of more buildings and inflict greater economic losses than did the September 11, 2002 attacks on the World Trade Center and the Pentagon. The National Defense University study proposes new policies for the federal government which would decrease the chances of an attack and reduce the cost in lives and money to the United States should one, nevertheless, occur.

  3. Multiple myeloma among atomic bomb survivors

    The relationship between multiple myeloma in Hiroshima and Nagasaki and the estimated exposure dose is discussed. From October 1950 to December 1976 multiple myeloma was observed in 22 of 72,802 a-bomb survivors (54,116 in Hiroshima; 18,686 in Nagasaki) who were examined periodically in a life span survey by the Radiation Effects Research Foundation. The incidence per 1,000 was roughly 0.97 in a group exposed to over 100 rad, 0.30 in a group exposed to 1 to 99 rad, and 0.21 in a group exposed to less than 1 rad. There was a statistical difference (p<0.05) in relative risk which standardized city, sex, and age according to the controls exposed to less than 1 rad. An increase in risk in a group exposed to a large dose was marked in survivors aged 20 to 59 at the time of exposure. Multiple myeloma was not observed in those under 20 or over 60 years. An increase in risk in the group exposed to a large dose became marked 15 years after exposure. It is believed that the age factor, in addition to radiation, specifically influenced the occurrence of disease. (Tsunoda, M.)

  4. Ellerman Bombs with Jets: Cause and Effect

    Reid, A; Scullion, E; Doyle, J G; Shelyag, S; Gallagher, P

    2015-01-01

    Ellerman Bombs (EBs) are thought to arise as a result of photospheric magnetic reconnection. We use data from the Swedish 1-m Solar Telescope (SST), to study EB events on the solar disk and at the limb. Both datasets show that EBs are connected to the foot-points of forming chromospheric jets. The limb observations show that a bright structure in the H$\\alpha$ blue wing connects to the EB initially fuelling it, leading to the ejection of material upwards. The material moves along a loop structure where a newly formed jet is subsequently observed in the red wing of H$\\alpha$. In the disk dataset, an EB initiates a jet which propagates away from the apparent reconnection site within the EB flame. The EB then splits into two, with associated brightenings in the inter-granular lanes (IGLs). Micro-jets are then observed, extending to 500 km with a lifetime of a few minutes. Observed velocities of the micro-jets are approximately 5-10 km s$^{-1}$, while their chromospheric counterparts range from 50-80 km s$^{-1}$....

  5. Observations and NLTE modeling of Ellerman bombs

    Berlicki, Arkadiusz

    2014-01-01

    Ellerman bombs (EBs) are short-lived and compact structures that are observed well in the wings of the hydrogen H-alpha line. EBs are also observed in the chromospheric CaII lines and in UV continua. H-alpha line profiles of EBs show a deep absorption at the line center and enhanced emission in the line wings. Similar shapes of the line profiles are observed for the CaII IR line at 8542 ang. It is generally accepted that EBs may be considered as compact microflares located in lower solar atmosphere. However, it is still not clear where exactly the emission of EBs is formed in the solar atmosphere. High-resolution spectrophotometric observations of EBs were used for determining of their physical parameters and construction of semi-empirical models. In our analysis we used observations of EBs obtained in the H-alpha and CaII H lines. We also used NLTE numerical codes for the construction of grids of 243 semi-empirical models simulating EBs structures. In this way, the observed emission could be compared with th...

  6. Synoptic conditions leading to extremely high temperatures in Madrid

    Garcia, R.; Prieto, L.; Hernandez, E.; Teso, T. del [Dept. Fisica de la Tierra II, Fac. CC. Fisicas, Univ. Camplutense de Madrid (Spain); Diaz, J. [Centro Universitario de Salud Publica, Univ. Autonoma de Madrid (Spain)

    2002-02-01

    Extremely hot days (EHD) in Madrid have been analysed to determine the synoptic patterns that produce EHDs during the period of 1955-1998. An EHD is defined as a day with maximum temperature higher than 36.5 C, a value which is the threshold for the intense effects on mortatility and it coincides with the 95 percentile of the series. Two different situations have been detected as being responsible for an EHD occurrence, one more dynamical, produced by southern fluxes, and another associated with a stagnation situation over Iberia of a longer duration. Both account for 92% of the total number of days, thus providing an efficient classification framework. A circulation index has been derived to characterise and forecast an EHD occurrence. This paper shows that EHD occur in Madrid during short duration events, and no long heat waves, like those recorded in other cities, are present. Additionally, no clear pattern can be detected in the EHD frequency; the occurrence is tied to changes in the summer location of the Azores high. (orig.)

    Two new titanates of strontium, lithium and a 3d metal, with the composition SrLiMTi4O11 (M=Cr,Fe), have been discovered. Single crystals were obtained by spontaneous crystallization from a high-temperature solution with LiBO2 as the solvent. The structure of SrLiCrTi4O11 was refined in the orthorhombic space group Pnma (Z=4), while SrLiFeTi4O11 appeared to adopt a four-times larger orthorhombic unit cell with Pbcn (Z=16). The structures can be described by a close-packed arrangement of Sr and O atoms. The unit cell contains six 'compact planes' perpendicular to [100] in the layer sequence ABACBC [(chc)2]. Ti and Cr or Fe atoms occupy some of the interstitial octahedral sites created, whereas Li atoms are in tetrahedral sites. Depending on the synthesis conditions of SrLiCrTi4O11, the distribution of Cr and Ti atoms on the four possible crystallographic sites is not the same. Having a similar compact-planes sequence, SrLiCrTi4O11 and SrLiFeTi4O11 structures differ in the arrangement of Sr and O atoms per layer of close packing, which also induces a correlated variation in the Li-tetrahedra distribution.

  8. Conversion from RSX-11D to RSX-11M or: did I really want to do it

    The LAMPF Nuclear Chemistry Data Acquisition System (DAS) is used to acquire and to process data from a variety of nuclear chemistry experiments. In June 1977, the DAS was upgraded to a PDP-11/34 and RSX-11D V6.2 and FORTRAN 4-PLUS V2.5. That software remained in use until January, 1984 even though the PDP-11/34 was replaced by a PDP-11/44, and a number of peripherals were added or replaced. The arrival and installation of an RA-60 disk system forced us to upgrade to RSX-11M V4.1 and FORTRAN-77 V5.0. This was not without much pain and many problems. There was a change in functionality, and some things did not work as they previously had worked. A description of some of the changes in the DAS and of the problems in going from the ancient to the current software will be given as well as an evaluation of the results obtained so far in the conversion

  9. Clinical study of aplastic anemia among A-bomb survivors

    In 90 patients with aplastic anemia who were seen at Dept. Med. RINMB, Hiroshima Univ. from 1962 to March, 1980, clinical findings of 33 A-bomb survivors (which included the second generation of the survivors) and those of 57 nonexposed patients were compared. No relationship was found between the age at the time of exposure and the period preceding onset of the disease. The A-bomb survivors showed higher neutrophil counts and higher reticulocyte counts than the nonexposed patients. There were less severe cases in the A-bomb survivors. There was no difference in the incidence of atypical aplastic anemia between the exposed patients and the nonexposed ones. No difference was found in overall survival (one-year and five-year survival rates) between the exposed and the nonexposed. The A-bomb survivors often had complete remission or maintenance of remission, and rarely had acute progression. These results suggested that clinical picture of aplastic anemia in the A-bomb survivors is different from that in the nonexposed patients. (Ueda, J.)

  10. Is Einstein the Father of the Atomic Bomb

    Lustig, Harry

    2009-05-01

    Soon after the American atomic bombs were dropped on Hiroshima and Nagasaki, the notion took hold in the popular mind that Albert Einstein was ``the father of the bomb.'' The claim of paternity rests on the belief that E=mc2 is what makes the release of enormous amounts of energy in the fission process possible and that the atomic bomb could not have been built without it. This is a misapprehension. Most physicists have known that all along. Nevertheless in his reaction to the opera Dr. Atomic, a prominent physicist claimed that Einstein's discovery that matter can be transformed into energy ``is precisely what made the bomb possible.'' In fact what makes the fission reaction and one of its applications,the atomic bomb, possible is the smaller binding energies of fission products compared to the binding energies of the nuclei that undergo fission.The binding energies of nuclei are a well understood consequence of the numbers and arrangements of protons and neutrons in the nucleus and of quantum-mechanical effects. The realization that composite systems have binding energies predates relativity. In the 19th century they were ascribed to potential and other forms of energy that reside in the system. With Einstein they became rest mass energy. While E=mc2 is not the cause of fission, measuring the masses of the participants in the reaction does permit an easy calculation of the kinetic energy that is released.

  11. Mortality statistics among atomic bomb survivors in Hiroshima Prefecture

    In a comparative analysis of mortality among atomic bomb survivors versus the non-exposed, both resident in Hiroshima Prefecture, it was found that in addition to leukaemia, malignant lymphoma, multiple myeloma, and cancers of the thyroid gland, breast, lung, esophagus, stomach, urinary organs and salivary gland which have been reported from the past to be elevated in risk among atomic bomb survivors, cancers of the colon, larynx, accessory sinuses, uterus, ovary and testis, diseases of the blood, cirrhosis of liver, hypertensive disease and diabetes mellitus were elevated in risk, but the risk of cerebrovascular disease, heart disease, peptic ulcer, gastroenteritis, senility, and accidents was lower than the non-exposed. The relationship of atomic bomb exposure to the relative risk of cancers of the lung, breast, uterus, and testis could be readily explained, but the relationship between atomic bomb exposure and the relative risk of cancers of many other sites, diseases of the blood, and other causes of death was inconsistent. One of the reasons why the risk of senility was low and the risk of diseases of the blood, malignant neoplasms, diabetes mellitus, and hypertensive disease was high is considered to be the higher diagnostic accuracy in atomic bomb survivors.

  12. ESR dosimetry for atomic bomb survivors and radiologic technologists

    Tatsumi-Miyajima, Junko

    1987-06-01

    An individual absorbed dose for atomic bomb (A-bomb) survivors and radiologic technologists has been estimated using a new personal dosimetry. This dosimetry is based on the electron spin resonance (ESR) spectroscopy of the CO 33- radicals, which are produced in their teeth by radiation. Measurements were carried out to study the characteristics of the dosimetry; the ESR signals of the CO 33- radicals were stable and increased linearly with the radiation dose. In the evaluation of the absorbed dose, the ESR signals were considered to be a function of photon energy. The absorbed doses in ten cases of A-bomb victims and eight cases of radiologic technologists were determined. For A-bomb survivors, the adsorbed doses, which were estimated using the ESR dosimetry, were consistent with the ones obtained using the calculations of the tissue dose in air of A-bomb, and also with the ones obtained using the chromosome measurements. For radiologic technologists, the absorbed doses, which were estimated using the ESR dosimetry, agreed with the ones calculated using the information on the occupational history and conditions. The advantages of this method are that the absorbed dose can be directly estimated by measuring the ESR signals obtained from the teeth of persons, who are exposed to radiation. Therefore, the ESR dosimetry is useful to estimate the accidental exposure and the long term cumulative dose.

  13. Recycling Of Bomb Produced Cl 36

    Lazarev, V.; Blinov, A.; Huber, Th.; Kubo, F.; Nolte, E.

    The success of accelerated mass-spectrometry (AMS) has allowed the measuring of very small quantities of radioactive nuclides with the ratio to their stable isotope up to 10-14. With the help of this method the concentration of 36Cl in natural samples can be investigated. The main sources of 36Cl in the atmosphere are a) The natural production in nuclear reactions induced by the interaction of high energy cosmic rays with atmospheric Ar. b) The production by the interaction of high neutron fluxes emitted by the nuclear weapon tests with stable chlorine. c) The production in different reactors with the following release (e.g. Chernobyl accident). The analysis of 36Cl time profile in Greenland showed the fast removal of chlorine from the atmosphere so that nowadays only the natural production of 36Cl is of importance. However the measurement of 36Cl in modern precipitation revealed the significant excess of its concentration over the simulated predictions. The recycling of chlorine as an explanation of the observed discrepancy is ar- gued. The biosphere could take up a part of the fallen down bomb produced 36Cl and releases it into the troposphere in the form of CH3Cl. To check the hypothesis the experiment to collect methyl chloride from the air and to measure 36Cl was set up. The high observed ratio 36 Cl/Cl proves that the chlorine recycling really takes place. Additionally, in order to get more information about the distribution of 36Cl the measurements of its concentration in lakes with long flushing times were performed. With the help of modeling the different sources of 36Cl can be distinguished. The dominant source of 36Cl in many Alpine lakes is chlorine, released during the accident on the Chernobyl nuclear power plant.

  14. Thyroid disorders in atomic-bomb survivors

    It is known from several studies, including those from RERF that radiation exposure can cause thyroid tumors (Socolow, N Engl J Med. 1963;268:406, Parker, Ann Intern Med. 1974;80:600). Effects of radiation on autoimmune thyroid disease are not well understood. We have conducted thyroid disease screening on a population of 2856 individuals from the Adult Health Study (AHS) cohort of atomic-bomb survivors for the period of 1984-1987. This study, which for logistical reasons involved survivors only from Nagasaki, revealed a statistically significant relationship between radiation dose and prevalence of solid nodules, including cancer, and that of autoimmune hypothyroidism (Nagataki, JAMA. 1994;272:364). Because the previous thyroid study was conducted only in Nagasaki, the new comprehensive thyroid disease screening study has been ongoing in Hiroshima and Nagasaki AHS participants since March 2000. For about 4,000 participants in Hiroshima and Nagasaki AHS cohort, thyroid ultrasonography, aspiration biopsy of nodules, thyroid function test, thyroid autoantibody (thyroid peroxidase antibody and thyroglobulin antibody) test by highly sensitive assay using enzyme linked immunosorbent assay were performed for the diagnosis of thyroid diseases. Analysis of data from the 1874 people examined through July 2001 (915 people from Hiroshima, 959 people from Nagasaki) provides evidence that thyroid cancer increases with radiation dose. The prevalence of positive result for thyroid autoantibody test is increased in the people exposed to relative low dose of radiation (0.01-0.99 Sv). Examination and measurements was completed in February 2003 for all patients. The analysis of these data is providing new and more complete insights into relationships between thyroid diseases and low doses of radiation

  15. The Rhetoric of "Unconditional Surrender" and the Decision to Drop the Atomic Bomb.

  16. Extension lectures: the effects of radiation from atomic bombing

    About 56,000 A-bomb survivors are living in Nagasaki city even today. Nagasaki citizens, whether they are A-bomb survivors or not, can not live without concerns on the existence of radiation effects. They have fears of any amount of radiation and are afraid that it may harm their life. As results of studies in the university on radiation effects are not familiar to the citizens, we have started extension lectures on 'the effects of radiation from A-bombing' to them since 1990. We discuss the problems as well as significance of the extension lectures by reporting the details of the extension lectures which we have managed in the past. (author)

  17. Forensic applications of 14C bomb-pulse dating

    After a brief review of the basics of 14C bomb-pulse dating, this paper presents two unique forensic applications. Particular attention is dedicated to the use of the 14C bomb-pulse to establish the time of harvest of illicit drugs such as heroin and opium. Preliminary measurements of 14C concentrations in milligram samples taken from seized drugs are presented. 14C bomb-pulse dating can determine whether drug distribution originates from stockpiles or recent manufacture, and support the action of law enforcement authorities against criminal organisations involved in drug trafficking. In addition, we describe the dating of wine vintages for a number of authenticated single label vintage red wines from the Barossa Valley - South Australia. Our results show that radiocarbon dating can be used to accurately determine wine vintages and therefore reveal the addition of unrelated materials of natural and synthetic origin

  18. Radiation risks related to the Hiroshima and Nagasaki bombs

    The biological effects of the atomic bombs dropped down on Hiroshima and Nagasaki are studied in detail. There is no significant genetic effect on the children of survivors. The genetic damage on survivors is a linear or quadratic function of the dose. The connection between cancerous tumours and the dose is studied in detail for small doses. Significant difference was found between the effects of the two bombs. Its main reason is that the radiation of the bomb on Nagasaki was primarily gamma radiation, while that of Hiroshima radiated fast neutrons and γ rays. It is shown that the mortality rate in people who received small dose of radiation is lower compared to those who did not receive radiation at all. (K.A.) 6 figs

  20. Epidemiologic study of meningioma in Nagasaki atomic bomb survivors

    Forty-five A-bomb survivors (10 men and 35 women) with surgically proven meningioma were examined, whose ages ranged from 45 to 80 years. According to distance from the hypocenter, 18 A-bomb survivors were exposed at <2,500 m and the other 27 were exposed at ≥2,500 m. The incidence of meningioma was significantly decreased in A-bomb survivors exposed farther from the hypocenter, revealing a high correlation between exposure distance and the incidence of meningioma. Since 1980, the incidence of meningioma was significantly increased in the <2,500 m exposed group than the ≥2,500 m exposed group. (N.K.)

    Atomic bomb survivors have been reported to have an increased risk of some cancers, especially leukemia. However, the risk of prostate cancer in atomic bomb survivors is not known to have been examined previously. This study examined the association between atomic bomb radiation and the incidence of prostate cancer among male Nagasaki atomic bomb survivors. The subjects were classified by distance from the hypocenter into a proximal group (

  5. Genetic instability in leukemic cells from atomic bomb survivors

    MSI (Micro Satellite Instability) analysis was enforced for 29 patients with AML (atomic bomb survivors 13 cases, unexposed persons 16 cases) who developed from 1986 to 1994. When the cases that alterations at two or more parts were recognized in micro-satellite analyses of leukemic cell were defined as MSI, 2 of 16 unexposed persons and 10 of 13 survivors were positive, and significant high rate was recognized (p<0.01) among survivors. This result suggest genetic instability in leukemic cell of atomic bomb survivors. (K.H.)

    1984-03-01

    Though a cold winter with snowfalls, in the fiscal year 1983, the number of the atomic-bomb sufferers using the Beppu Atomic-bomb Center (a medical hot spring) was large in January and February, 1984; throughout the fiscal year, the total number was about 3,800 persons. The diseases of the sufferers, mostly in locomotion organs, are such as osteoarthritis of spine, lame hip and knee arthropathy. Being the typical diseases for which hot spring treatment is good, the effect is clear, and those desiring to enter the Center twice in a year are increasing. The situation of usage of the Center from April, 1983, to March, 1984, is described.

  11. Degenerative diseases of the nervous system in atomic bomb survivors

    Degenerative diseases (DD) of the nervous system were observed in 169 of 23,418 A-bomb survivors enrolled in a cohort adult health survey. Senile dementia and parkinsonism accounted for 76 % of the DD. The incidence of DD tended to be higher with increasing exposure doses for women. This was significant for younger women at the time of bombing. No dose-dependence was seen for occurrence of DD in men. There was no significant difference in the incidence of DD between Hiroshima's and Nagasaki's survivors. (Namekawa, K.)

  12. Why didn't Hitler get the atomic bomb

    This bibliographical note presents a book in which the author reports his historical studies on the Nazi's nuclear activities as, by the end of the 1930's, Germany was probably the leader in this domain. He mentions and describes the various programs that were launched between 1939 and 1945, discusses some evidences related to the fact that the Germans probably tried to master nuclear energy production, and that they might have tested a weapon containing fissile materials (probably a dirty bomb). The author analyses the reasons of the failure of this nuclear sector: a lack of organization, war and bombings, and a relative lack of interest of political authorities

  16. Bomb Tritium in the Pacific Ocean

    During 1959--1973 bomb-produced tritium was monitored in surface seawater from 15 stations in the Pacific Ocean. Some 500 tritium determinations were carried out. Between 1965 and 1972 a series of subsurface samples from 49 locations in the Pacific Ocean was measured, and tritium concentrations as a function of depth were determined. The determinations had a standard error of +-4% and an uncertainty in the zero value of about 0.17 tritium unit. The most significant oceanographic conclusions that must be drawn from these data can be summarized in the following way: (1) Lateral flow along contours of constant density is the major factor controlling the tritium distribution in the surface and subsurface waters of the Pacific Ocean. Input of tritium into the water below the mixed layer occurs between 45 degree and 30 degree N and south of 60 degree S. The sinking of water in the mid-Pacific at 30 degree N and its flow toward the equator was previously recognized from the presence of a salinity maximum below the thermocline. The southward component of the rate of this flow is estimated to be 1.3+-0.5 cm/s. In many other areas the tritium content of water under the mixed layer is undoubtedly also due to local sinking of surface water and subsequent lateral subsurface flow. (2) An upper limit for the coefficient of vertical eddy diffusion can be calculated. This upper limit of 0.3 cm2/s is well below estimates derived by other methods, but it agrees well with the upper limit of 0.2 cm2/s derived from tritium measurements in the Sargasso Sea. It appears that transport across lines of constant density is much slower than previously assumed. (3) The mean lifetime of water in the mixed layer of the North Pacific Ocean varies greatly with geographical location. North of 10 degree N the average residence time is between 9 and 15 years, depending on the assumed rate of the molecular exchange of water between atmosphere and ocean

  20. Seismological investigation of earthquakes in the New Madrid Seismic Zone

    Earthquake activity in the New Madrid Seismic Zone had been monitored by regional seismic networks since 1975. During this time period, over 3,700 earthquakes have been located within the region bounded by latitudes 35 degrees--39 degrees N and longitudes 87 degrees--92 degrees W. Most of these earthquakes occur within a 1.5 degrees x 2 degrees zone centered on the Missouri Bootheel. Source parameters of larger earthquakes in the zone and in eastern North America are determined using surface-wave spectral amplitudes and broadband waveforms for the purpose of determining the focal mechanism, source depth and seismic moment. Waveform modeling of broadband data is shown to be a powerful tool in defining these source parameters when used complementary with regional seismic network data, and in addition, in verifying the correctness of previously published focal mechanism solutions

  1. Diagenesis of Late Miocene micritic lacustrine carbonates, Madrid Basin, Spain

    Wright, V. P.; Zarza, A. M. Alonso; Sanz, M. E.; Calvo, J. P.

    1997-12-01

    Mud-grade lacustrine limestones of Miocene age from the Madrid Basin, Spain, reveal varied and complex diagenetic histories. Microporous micrites occur as well as micrites with anhedral mosaics. The micrites have recrystallized from a metastable precursor, in part under sub-oxic meteoric diagenetic conditions probably before extensive karstification in the Pliocene. The absence of aragonite relics, their mainly micritic microfabric, low Sr content and covariant trend of Sr and Mg suggest that the micrites formed from mainly high-magnesian calcite muds. Lacustrine micrites can be compared to marine forms and criteria used to assess the composition of the marine precursor muds can be applied to lacustrine limestones to complement other techniques to identify original lake water compositions.

  2. NAO influence on extreme winter temperatures in Madrid (Spain)

    2002-12-01

    Extremely cold days (ECDs), with minimum temperatures lower than -4.6 C, have been analysed for Madrid. This threshold corresponds to the 5th percentile of the period 1963-1999. Adopting a case analysis approach, five synoptic patterns have been identified that produce these extremely low temperatures. Three of them are associated with cold air flows over the Iberian Peninsula, and the other two with a lack of significant circulation over the region. A non-linear association with the North Atlantic oscillation (NAO) has been identified using log-linear models. The NAO positive phase leads to an increase in the winter frequency of those synoptic patterns associated with stagnant air flow over Iberia, while those characterised by cold, northern flows do not appear to be similarly influenced.

    Full Text Available This school for boys and girls has been built by the Fundación Benéfica «Santa Elena», at Villarejo de Salvanés, near Madrid. It has four classrooms for girls, two for boys, a residence for the nuns who look after the girls, two dwellings for male teachers, one for the caretaker, and a hall-cum-chapel, forming part of the nuns' precinct. The main porch entrance provides an element of integration for the various parts of the school; which otherwise are absolutely independent of each other, and are designed to make it easy to add further extensions to each section of the school at a later date.Este grupo escolar para niñas y niños, construido por la Fundación Benéfica «Santa Elena», en Villarejo de Salvanés (Madrid, consta de: cuatro clases para niñas; dos para niños; una residencia para las monjas que atienden a las niñas; dos viviendas para maestros; una para el subalterno del grupo, y el salón de actos-capilla, incorporado a la Comunidad. Todos los elementos que componen el conjunto están relacionados entre sí a través del porche principal de acceso, y fueron proyectados y realizados de forma que posean una independencia absoluta y permitan a la vez posibles amplificaciones futuras.

  4. Heisenberg's war. The secret history of the German bomb

    The history of Second World War Germany's 'Uranium Project', which often is referred to as the 'myth of the German atomic bomb', has been attracting the mind's of secret service men, futurologists, historians and journalists since after the end of the war it has become possible to lift the veil of secrecy. Powers book adds another one to the many investigations published since them. His approach to the piece of history starts with Heisenberg's visit to the U.S.A. in summer 1939, describes the plans of the German Heereswaffenamt pursued with the Uranium Project, and their counterpart on the side of the Allied Forces where German scientists, as immigrants in England and in the U.S.A., were doing their best to launch research for the development of an atomic bomb. The end of this 'competition' is marked by the internment of the ten German scientists and bomb specialists in Fall Hall. The leading story of the book centers on the small group of scientists around Heisenberg, who cleverly 'torpedoed' the development of the German atomic bomb in the years from 1939 until 1944. (HP)

  5. Aplastic anemia and related disorders in atomic bomb survivors

    Whether the incidence of aplastic anemia significantly increases due to the later effect of atomic-bomb radiation was studied. After the data of aplastic anemia which occurred within 1950 - 1973 were evaluated and the diagnoses of the cases were certified, the incidence of aplastic anemia per 109,000 inhabitants of the cities of Hiroshima and Nagasaki was calculated and compared according to the dose of atomic-bomb radiation. There was no increase in the incidence according to an increase in radiation dose, and there was no fact that aplastic anemia increased in a certain period either. Most of the atomic-bomb survivors who were close to the epicenter and were clinically diagnosed as aplastic anemia had leukemia lesion or myeloid proliferating lesion, and it is likely to be that pathological changes resembling aplastic anemia may appear in a certain phase of myeloid proliferation or as a phenotype of myeloid proliferation. An evaluation was made on cases of aplastic anemia of other groups, but the doses of atomic-bomb radiation which they received were not so much to give effect on the bone marrow except only two cases. (Ueda, J.)

  6. Experimental simulation of A-bomb gamma ray spectra: Revisited

    It has been reported recently that the A-bomb gamma ray spectra received by the colon of the average Japanese survivor of Hiroshima and Nagasaki may be experimentally simulated using a hospital-based Philips SL15 linear accelerator. The simulated A-bomb gamma radiation may be used in radiobiology experiments to determine, amongst other things, the biological effectiveness of the A-bomb gamma radiation. However, in that study, the electron beams from the linear accelerator were poorly defined and photon contamination was ignored. In the study reported here, a Varian Clinac 2100C linear accelerator has been used for the same purpose but with photon contamination included in better defined output electron beams. It is found that the A-bomb gamma radiation can still be matched to an acceptable degree (<10%). The cause of the slightly poorer fit was due mainly to the different ranges of energies available from the linear accelerators used. The absorbed dose received by model breasts was also estimated in this study for the same situations as in the previous study. The ratio of the breast to colon doses was found to be only (3.9 ± 4.0)% low compared with the expected values of 1.17 and 1.16 for Hiroshima and Nagasaki, respectively. These results provide further confirmation of the acceptability of the simple cylindrically symmetrical body models employed in these studies to represent the average Japanese survivor. (authors)

  7. Lymphocyte cytotoxicity of colchicine in Hiroshima atomic bomb survivors

    The cytotoxicity of colchicine for the peripheral blood lymphocytes of 151 Hiroshima atomic bomb survivors and their controls was determined. No radiation effect was found, but modest age-related changes for the initial number of vialble cells and for the cytotoxicity of colchicine were observed. (author)

  8. Lack of strategic insight: the "dirty bomb" effort.

    Goffman, Tom

    2009-01-01

    Multiple countries including the United States and France are investing heavily in countermeasures to the threat of a "dirty bomb." All of the machinery simply involves a variation on a Geiger counter that picks up excess photon irradiation. Classically, a "dirty bomb" is defined as a dangerous radioactive material mixed in a variety of ways with high explosive, so when detonated, radioactive material is dispersed. Solid radioactive material such as Cesium or Cobalt sends off very penetrating ('hard') photons from which one cannot simply be protected by sheet lead or a heavy door. For official occasions with dignitaries of State, such a bomb could prove a modest distraction, but simple radiation physics suggests such a bomb would be limited in the damage it could cause, would largely be a mess to be cleaned up by an appropriately trained crew, would involve a very confined area, and thoroughly fails to comprehend the mentality of al-Queda 'central' that wishes to follow 9/11 with an equal or greater show of terrorist force. The author would argue this sort of mind-think occurs when you have too few people in the hard sciences in your intelligence sections. PMID:19739461

  9. Satisfaction in life of elder A-bomb survivors

    1500 A-bomb survivor aged more than 65 are sampled and the questionnaire was performed by mailing. 1329 (88.6 %) responded and 937 from the age less than 80 were statistically anylized. Fairly good satisfaction was felt on their daily life, including dwelling, income, work, health and family. (J.P.N.)

  10. Pre- and post-bomb radiocarbon in fish otoliths

    Kalish, John M.

    1993-02-01

    Measurements of radiocarbon in seawater dissolved inorganic carbon (DIC), or suitable proxies such as hermatypic corals, are a valuable source of information on carbon flux and ocean circulation. However, knowledge of the global distribution of both pre- and post-bomb radiocarbon is limited due to the sources of these data. Suitable hermatypic corals are restricted to shallow tropical and subtropical waters and oceanographic collections of seawater are prohibitively expensive. What is needed is a proxy for ocean radiocarbon that can be collected at most latitudes and depths, and which can be reliably aged. Here I report accelerator mass spectrometry analyses of radiocarbon from selected regions of fish otoliths and show that such measurements are suitable for determining both pre- and post-bomb radiocarbon in all oceans and at most depths. Radiocarbon data obtained from otoliths can extend our knowledge of carbon flux in the oceans and atmosphere and help to develop further understanding of the fate of atmospheric CO 2 and ocean circulation. The data presented here represent the first pre- and post-bomb time series of radiocarbon levels from temperate waters. Furthermore, I demonstrate that the dramatic increase in radiocarbon in the atmosphere and oceans, attributable to the atmospheric testing of thermonuclear bombs during the 1950's and 1960's, provides a chemical mark on fish otoliths that is suitable for the validation of age in fishes.

    Water resources and water footprint of the production and consumption in Madrid region were estimated, considering blue water (water resources), green water (soil moisture), grey water (polluted water) and virtual water (water trade in products imported and exported in the region). Water resources in Madrid relay mainly in surface waters and rainfall, so the periodic occurrence of meteorological droughts implies the scarcity of water supply. The main users of blue water are households, munici...

  17. Leukemia among a-bomb survivors living in Hiroshima city, 1971-1978

    The death from leukemia among Hiroshima citizens from 1971 to 1978 was investigated. The total number of dead citizens was 241, and 64 of them were a-bomb survivors. Thirty-seven of a-bomb survivors were exposed to a-bomb within 2 km from hypocenter. Seventy-seven of remaining 177 citizens were born after the explosion of a-bomb, but they were not children of a-bomb survivors exposed directly to a-bomb. The mortality of a-bomb survivors exposed near the hypocenter was 1.67 (within 2 km) - 2.51 (within 1.5 km) times that of those exposed far from the hypocenter. The mortality of a-bomb survivors exposed within 1.5 km was significantly high. The death risk from leukemia was significantly high in women. The estimated exposure dose was over 1 rad in 25 of abovementioned 37 a-bomb survivors, and it was over 10 rad in 21 and over 100 rad in 10 of 25. Seven of 10 a-bomb survivors exposed over 100 rad were women. The age at the exposure was under 10 years in 1, teens in 1, twenties in 2, and over thirty in 6. The type of leukemia was acute in 8 and chronic in 2. Both types were myelogenous leukemia. Five of these 10 a-bomb survivors died after 1976. (Tsunoda, M.)

  18. Automatic behavior sensing for a bomb-detecting dog

    Nguyen, Hoa G.; Nans, Adam; Talke, Kurt; Candela, Paul; Everett, H. R.

    2015-05-01

    Bomb-detecting dogs are trained to detect explosives through their sense of smell and often perform a specific behavior to indicate a possible bomb detection. This behavior is noticed by the dog handler, who confirms the probable explosives, determines the location, and forwards the information to an explosive ordnance disposal (EOD) team. To improve the speed and accuracy of this process and better integrate it with the EOD team's robotic explosive disposal operation, SPAWAR Systems Center Pacific has designed and prototyped an electronic dog collar that automatically tracks the dog's location and attitude, detects the indicative behavior, and records the data. To account for the differences between dogs, a 5-minute training routine can be executed before the mission to establish initial values for the k-mean clustering algorithm that classifies a specific dog's behavior. The recorded data include GPS location of the suspected bomb, the path the dog took to approach this location, and a video clip covering the detection event. The dog handler reviews and confirms the data before it is packaged up and forwarded on to the EOD team. The EOD team uses the video clip to better identify the type of bomb and for awareness of the surrounding environment before they arrive at the scene. Before the robotic neutralization operation commences at the site, the location and path data (which are supplied in a format understandable by the next-generation EOD robots—the Advanced EOD Robotic System) can be loaded into the robotic controller to automatically guide the robot to the bomb site. This paper describes the project with emphasis on the dog-collar hardware, behavior-classification software, and feasibility testing.

    1999-03-01

    Since the atomic bomb explosions in Hiroshima and Nagasaki, high incidences of leukemia, thyroid cancer and other tumors have been reported as atomic bomb-induced tumors. We investigated the incidence of meningioma among Hiroshima atomic bomb survivors. Sixty-eight patients surgically treated for meningioma who had been within 2.0 km of the hypocenter of the explosion were identified. Six hundred and seven non-exposed patients with meningioma were also studied. Treatment dates were from 1975 to 1992. The incidences of meningioma among 68 subjects within 2.0 km and 607 non-exposed patients were 8.7 and 3.0 cases per 10{sup 5} persons per year, respectively. The incidences of meningioma among the survivors of Hiroshima in 5-year intervals since 1975 were 5.3, 7.4, 10.1, and 14.9, respectively. The incidences of meningioma classified by distances from the hypocenter of 1.5-2.0 km, 1.0-1.5 km and less than 1.0 km were 6.3, 7.6 and 20.0, respectively. The incidences of meningioma classified by doses to the brain of 0-0.099 Sv, 0.1-0.99 Sv and more than 1.0 Sv were 7.7, 9.2 and 18.2, respectively. The incidence of meningioma among Hiroshima atomic bomb survivors has increased since 1975. There was a significant correlation between the incidence and the dose of radiation to the brain. The present findings strongly suggest that meningioma is one of the tumors induced by atomic bombing in Hiroshima. (author)

    Our department of Neuropsychiatry has clarified the clinical features of several mental disorders and surveyed the causes of those disorders from the psychosocial aspect using the methodology of epidemiological psychiatric approach. Using this previous research experience, we began a long-planned study to examine the mental health state of atomic bomb survivors. Fifty-one years have passed since the atomic bombing, and the survivors must have suffered various psychosocial stresses, other than any direct effect on the central nervous system from exposure to radiation, and it is assumed that victims` mental state has been affected in various ways as a result. The subjects of the survey were 7,670 people who had regular health examinations for atomic bomb survivors during the study period of three years and who consented to participate in the study. Of the total, 226 subjects were selected for a second phase according to the results of the General Health Questionnaire 12-item Version which was used in the first phase of the survey. The results were as follows: 1. The distance from the hypocenter was related to the degree of ill health, and the percentage of people with a high score was greater among those exposed to the atomic bomb in proximity to the hypocenter. 2. 14.6% of the subjects were diagnosed as having some kind of mental disorders according to clinical interviews by trained psychiatrists. These results had not expected prior to the study. On the based of the study, we will try to establish a mental health support system for atomic bomb survivors. (author)

  3. Leukemia among atomic bomb survivors during the 1980s

    On the basis of the dosimetry system 1986, exposure doses were determined in a cohort of 86,502 subjects for the Life Span Study during the period 1950-1985. A total of 248 people were found to develop leukemia in Hiroshima and Nagasaki cities. This is an analysis of the 248 patients with leukemia in connection with exposure doses, years after A-bombing, age at the time of A-bombing, relative risk, and background. An average exposure dose was 0.20 Gy for Hiroshima and 0.22 Gy for Nagasaki. Relative risk for leukemia tended to show a linear increase in proportion to exposure doses. This was significant for acute myelocytic leukemia (AML), regardless of whether A-bomb survivors came from Hiroshima or Nagasaki. The younger the age at the time of A-bombing was, the higher excess relative risk for acute lymphocytic leukemia (ALL) and chronic myelocytic leukemia (CML) was. For AML, however, it was independent of the age at that time. These findings were similar in Hiroshima and Nagasaki A-bomb survivors, irrespective of age. As for non-exposed group, the incidence of CML was three times higher in Hiroshima citizen than Nagasaki citizen. Similarly, Hiroshima citizen had a 1.6 fold incidence of AML. There was no significant difference in the incidence of ALL between the cities. The incidences of both AML and ALL tended to increase more and more with aging, but the prevalences tended to increase in younger generation. An increased incidence of CML was associated with aging alone. (N.K.)

  5. Imaginary Savior: the image of the nuclear bomb in Korea, 1945-1960.

    Kim, Dong-Won

    2009-01-01

    Two atomic bombs dropped on Hiroshima and Nagasaki in August 1945 brought the unexpected liberation of Korea from the 35-year Japanese occupation. Koreans therefore had a very favorable and positive image of the nuclear bomb and nuclear energy from the beginning. The image of the nuclear bomb as "savior" was strengthened during the Korean War when the United States openly mentioned the possible use of the nuclear bomb against North Korean and Chinese military. After the end of the Korean War in July 1953 South Koreans strongly supported the development of the nuclear bomb in order to deter another North Korean invasion. When the US government provided South Korea with a research nuclear reactor in the late 1950s, most South Koreans hailed it as the first step to developing their own nuclear bomb. This paper will analyze how and why the savior image of the nuclear bomb originated and spread in Korea during the 1950s. PMID:20518158

  8. Medical examination of A-bomb survivors on Nagasaki A-bomb Casualty

    Medical examination of A-bomb survivors was described and discussed on history, time change of examinee number, action for subjects not examined, change of prevalence, cancer examination, examination for the second generation, and education and enlightenment. Free examination of the survivors was begun in 1953 and the present casualty was made in 1958 on the law for medical care for the survivors. Systematic examination started from 1967 and the examination for the 2nd generation, from 1974. Cancer examination was from 1988. The number of the survivors was the maximum of 82,439 in 1974 and decreased to 61,388 in 1994, when the actual number of examinees, which being rather settled recently, was 32,294 and their average age was 64 y. The examination is done by tour or at the Center. Subjects receive the information of the examination twice by mail. Hematopoietic diseases like anemia, hepatic ones, metabolic and endocrinic ones like diabetes, renal impairment and others (mostly hyperlipidemia) are increasing recently. The number of examinees for cancer is increasing. Lung cancer is examined by the direct roentgenography, gastric cancer by transillumination, and other cancers like myeloma, those in large bowel, uterus and mammary gland, by the respective suitable methods. Health education and enlightenment have been conceivably effective. (H.O.)

  10. Mortality of A-bomb survivors in Nagasaki and Hiroshima

    A data base of A-bomb survivors in Nagasaki has been maintained at Division of Scientific Data Registry, Atomic Bomb Disease Institute at Nagasaki University School of Medicine. The data base include personal histories, records of health checks and cause of death. We have published the mortality of non-cancerous disease of A-bomb survivors using old dose estimation system, T65D, elsewhere. The mortality of non-cancerous disease was lower than controls for a dose range 50-99 cGy in male. We reanalyzed the mortality of non-cancerous disease using new dose estimation system, ABS93D. It's result was lower than controls for a dose range 31-40cGy in male. We compared the results of A-bomb survivors in our database with those or LSS's population, RERF. (1) Radiation dose for survivors in Nagasaki have been estimated by Atomic Bomb Survivor 1993 Dose (ABS93D). To study the mortality rates of A-bomb survivors for the period of 1971 through 1994, we selected 2,743 persons (dose estimate available) and age-matched 8,229 persons as control who were alive in 1971. (2) Another population is Life Span Study by Radiation Effect Research Foundation (RERF). RERF opened the data from 1950 to 1985. The data on deaths are stratified by city, sex, age radiation dose, the observed period and cause of death, yielding 3,640 strata. (1) The study resulted in that males exposed to 31-40cGy showed lower mortality from non-cancerous diseases than that of control. (2) Relative risk of mortality from all causes is lower than controls for a dose range 6-19cGy adjusted for sex, age, and period. Relative risk of mortality from non-cancerous disease is significantly lower than controls for a dose range 6-49cGy adjusted for sex, age, and period. But result of adjusted for city is no difference. (author)

The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the Comunidad Autonoma de Madrid. (Author) 39 refs

  12. Complejo parroquial de Santa Ana, en Moratalaz, Madrid

    Fisac, Miguel

    1967-06-01

    Full Text Available This church is sited at Moratalaz, a modern district of low rent houses in Madrid, and the architect has attempted to represent in the design the liturgical concepts developed in the Vatican II Council. These precise ideas have been expressed in the architecture by means of highly plastic symbols. In addition, the planform is very functional and the reinforced and prestressed concrete have been almost the only material used: so that the construction medium is also in accord with the modern nature of the design. The shapes, the space arrangement and everything which might seem a capricious creation of the artist in fact are the result of a detailed analysis of function and reason.Este complejo parroquial se ha levantado en Moratalaz, que es un barrio popular de la capital de España, procurando imprimir y recoger todas las premisas litúrgicas marcadas por el Concilio Vaticano II. El arquitecto ha plasmado sus precisas ideas en un edificio de gran expresividad plástica y de planta orgánica y eficaz, utilizando, casi exclusivamente, un material de nuestro tiempo: hormigón armado y pretensado. Las formas, la disposición de espacios y todo cuanto puede parecer caprichosa creación del artista, no son, en realidad, sino resultado de un cuidadoso estudio de funcionalismo racional y utilitario.

  18. Investigation of stomach diseases in atomic bomb survivors, (3)

    Mass examinations of the stomach were performed on 13,412 a-bomb survivors from Oct. 1975 to Mar. 1979. The necessity rate for detailed examinations was 13.6% on the average, and it was a little lower than the average in Japan. That in women was higher than that in men. The performance rate of detailed examinations was very high (91.8%), which might be influenced by active appeals to have detailed examinations. The estimated discovery rate of stomach cancer was 0.27% on the average, and it was higher than that in mass examinations of Chugoku and Shikoku districts. A relationship between the estimated discovery rate of stomach cancer and exposure conditions was not clarified. The discovery rate of stomach cancer was supposed to be influenced strongly by aging of a-bomb survivors. (Tsunoda, M.)

    1998-12-01

    It was investigated what blood disorders except leukemia increased the relative risk with dose dependency in atomic bomb survivors. Subjects were 217 patients of atomic bomb survivors in Hiroshima and Nagasaki, who had blood disorders except leukemia and died between 1950 and 1990. Their medical records were analyzed and their diagnoses were reevaluated. Sixteen cases were diagnosed as the aplastic anemia and 12 as the myelodysplastic syndrome (MDS). In the aplastic anemia, there was no correlation between the exposure dose and the mortality. In MDS, the excess relative risk (ERR)/bone marrow exposure dose of 1 Sv was very high (13.0). These results supports the hypothesis that MDS would be broken out by the clonal abnormality of the hematopoietic stem cell and radiation exposure could cause the appearance of the abnormal stem cell clone. (K.H.)

  20. Study of biochemical examination among A-bomb survivors

    Biochemical findings were compared in 1003 A-bomb survivors exposed at ≤1900 m from the hypocenter and 1003 age- and sex-matched A-bomb survivors exposed at ≥3,000 m. Mean and abnormal values for lung function, such as total protein, GOT and GPT, did not differ in two groups of both men and women. However, mean values of both total cholesterol and neutral fat were significantly higher in the ≤1900m group than in the ≥3000 m group, irrespective of sex. Similarly, the ≤1900 m group had a significantly higher incidence of abnormal values for these items than the ≥3000 m group. (N.K.)

  1. Problems in dosimetry study in the Hiroshima atomic bomb

    Dosimetry study 1986 (DS86) was constructed by the effort of US and Japanese groups and used afterward at Radiation Effects Research Foundation. The DS86 has been used to estimate radiation risks for cancer induction of radiation based on the epidemiological study of atomic bomb survivors. However, discrepancy between neutron-induced data and calculation based on DS86 has been observed. The discrepancy was found in the evaluated neutron dose in Hiroshima. To find the reason of the discrepancy, experimental study were continued for more than 10 years among Japanese and US groups. However there was no answer. In this review, the activities of the Japanese groups are explained and a model to explain the discrepancy is shown. The new US and Japan joint study is beginning and effort to evaluate atomic bomb dose for survivors are still continuing. (author)

  3. By emotion, no atomic bomb and no blackhole

    Shin, Philip

    2011-10-01

    As to be, we glory to God and that is basic theology for christian. And I want to say that BE means just thinking. There is no clue of nature and no proposition to prove it. I just believe by feeling and emotion. I trust that it can be the physic really. As for me, I believe when there is atomic bomb, than anytime it has to blow out the world each time of we are living. So the atomic bomb we thinking is just accident and not by the atomic theory. Also when there is blackhole, than there must be the wall to block me forever and never to walk again. So there are no blackhole. And these two subject is the best two subject for the physic.

  4. Physicists and the 1945 Decision to Drop the Bomb

    Byers, N

    2002-01-01

    In 1943 fear that the German war machine might use atomic bombs was abating and among physicists another fear was taking its place - that of a postwar nuclear arms race with worldwide proliferation of nuclear weapons. Manhattan Project scientists and engineers began to discuss uses of nuclear energy in the postwar world. Niels Bohr, Leo Szilard, James A. Franck and others launched a concerted effort to lay groundwork for international control of the technology. Realizing the devastation nuclear weapons could cause and that they could be made and delivered much more cheaply than conventional weapons of the same power, they tried to persuade policy makers to take into account long range consequences of using atomic bombs and not base their decisions on short range military expediency alone. They met with little success. The scientists' main message, unheeded then and very relevant now, is that worldwide international agreements are needed to provide for inspection and control of nuclear weapons technology. Thei...

  5. Analytic treatment of the black-hole bomb

    A bosonic field impinging on a rotating black hole can be amplified as it scatters off the hole, a phenomenon known as superradiant scattering. If in addition the field has a nonzero rest mass μ, the mass term effectively works as a mirror, reflecting the scattered wave back towards the black hole. In this physical system, known as a black-hole bomb, the wave may bounce back and forth between the black hole and some turning point, amplifying itself each time. Consequently, the field grows exponentially over time and is unstable. In this paper we study analytically for the first time the phenomenon of superradiant instability (the black-hole bomb mechanism) in the regime Mμ=O(1) of greatest instability. We find a maximal instability growth rate of τ-1=1.7x10-3M-1. This instability is 4 orders of magnitude stronger than has been previously estimated.

  7. Food habits in atomic bomb survivors suffering from malignant neoplasms

    Food habits were surveyed in patients admitted to 13 hospitals in Nagasaki prefecture and other prefectures to compare the incidence of malignant neoplasms according to the food intake between atomic bomb exposed group and non-exposed group. The incidence of malignant neoplasms was significantly higher in male patients having the low intake of milk and salted fish than in those having the high intake of them in atomic bomb exposed group, while it was significantly higher in male patients having the low intake of potatoes and milk and in female patients having the low intake of boiled fish paste than in those having the high intake of them in non-exposed group.

  8. Hot spring therapy of atomic bomb exposed patients, (9)

    The following description shows the statistics and the results of medical examinatin concerning the patients utilized Beppu Atomic Bomb Center from April, 1977, to March, 1978. Number of persons utilized the center was 3904, and 20285 man-days in total. Number of case treated there was 268. Number of diseases amounted to 442 of 66 sorts, excluding temporary of acute diseases such as acute entergastritis and cold diseases, etc. According to the report by the Ministry of Health and Welfare, atomic bomb-exposed persons show twice as much rate of incidence as normal persons, and owing to aging, many of them have more than two kinds of diseases. Among the diseases, 60 cases were hypertension, 32 heart disease, 30 knee-arthritis, 26 diabetes, 25 hepatitis, 23 spondylosis deformans, etc. Among 268 cases treated by hot spring therapy, 6 were totally cured, and 252 showed alleviation, while 10 showed no change.

  9. Destroying of chemical and oil industry, bombing of energy sources and use of depleted uranium ammunition during NATO bombing in FR Yugoslavia

    During the NATO bombing of the FR Yugoslavia from March 24 to June 10, 1999, according to NATO's data, there were 34 250 takeoffs of the 1200 aircrafts; 367 000 tonnes of kerosine were consumed; there were 400 Tomahawk cruise missiles and 130 air-to-ground missiles. It is estimated that 22 000-79 000 tonnes of explosives were dropped; in addition to 20 000 smart bombs and 5000 conventional bombs of various weight and purposes. The bombing had the characteristics of an ecological war, among other things. During the air strikes A-10 aircrafts fired shells with depleted uranium from 30 mm guns. According to NATO estimates, around 31 000 projectiles were fired (298 g of depleted uranium for each bullet, and more than 10 tonnes of uranium-238 as a contaminating agent), and according to the Yugoslav Army estimated, around 50 000 were fired. Some radiological, chemical and ethical consequences of NATO bombing in FR Yugoslavia are reviewed. (author)

  10. Chromosome survey for children of A-bomb survivors

    To investigate chromosomes from children of A-bomb survivors, cytogenetic survey has been started in 1967 by the ABCC and completed in 1985 by the succeeding RERF. This paper is designed to overview the cytogenetic survey and to discuss the cytogenetic effects of A-bomb radiation. A cohort of 16,298 children of A-bomb survivors, which were collected from mortality survey population in 1974, was enrolled in this survey and was divided into two groups: the proximally exposed group (n=8,322, whose parents exposed to estimated doses of 0.01 Gy or more within 2,000 m from the hypocenter) and the distally exposed group (n=7,976, those exposed to 0.005 Gy or less far from 2,500 m or not in the city). Three chromosomal aberrations were identified: sex chromosome aberrations consisting mainly of XYY, XXY, and mosaic; structural abnormality of autosomes consisting mainly of translocation and inversion; and trisomy of autosomes. Overall, the incidence of chromosomal aberrations was higher in the distally exposed group (6.39%) than the proximally exposed group (5.17%). According to the type of chromosomal aberrations, the incidences of both sex chromosomes and structural abnormality of autosomes were slightly higher in the distally exposed group (0.30% and 0.34%) than the proximally exposed group (0.23% and 0.28%). Trisomy of autosomes was identified in only one child in the proximally exposed group. These findings failed to demonstrate the rationale for the cytogenetic effects of A-bomb radiation; however, cytogenetic risk of radiation has not been denied completely. (N.K.)

  11. Surveys right after the atomic bombing and a relief squad

    Mine, Mariko [Nagasaki Univ. (Japan). School of Medicine

    1998-12-01

    An outline of four survey reports right after the atomic bombing in Nagasaki and Hiroshima is introduced. The report of Manhattan District Atomic Bomb Investigating Groups: The subjects of this survey were 900 inpatients in Nagasaki (for 16 days from September 20) and Hiroshima (for 5 days from October 3). Two hundreds and forty-nine patients (16%) died. In cases died without injury, the severe symptoms were alopecia, purpura, hemorrhage, oral cavity and pharynx lesion, vomiting, diarrhea and fever. The residual radioactivity measured at six weeks later was 6-25 roentgen in Hiroshima and 30-110 roentgen in Nagasaki (Nishiyama riverhead area). These values were lower than the predicted value from the clinical consequence. The report of Joint Commission for the Investigation of the Atomic Bomb: Following the above survey, about 6500 subjects were investigated both in Nagasaki and Hiroshima. Incidence of alopecia was investigated by shielded situation at a spot of 2.1 to 2.5 km from a blast center. It was 7.2% of outdoors (shielded: 7.3%, non-shielded: 17.4%) and 2.9% of indoors. The report of the Special Committee for Atomic Bomb Casualty Investigation and Research of the Scientific Research Council of Japan: General part of the report consists of medical part and physical part, and reports from each university were classified and listed in the supplement. Survey of Nagasaki Medical College (not in public): About 8000 subjects were investigated from October to December. Data were gathered up about lethality, time of death, injury and radiation sickness, etc. There was also autograph of a relief squad of the Nagasaki Medical College. (K.H.)

  12. Monitoring exposure to atomic bomb radiation by somatic mutation.

    Akiyama, M; Kyoizumi, S; Kusunoki, Y; Hirai, Y; Tanabe, K; Cologne, J B

    1996-05-01

    Atomic bomb survivors are a population suitable for studying the relationship between somatic mutation and cancer risk because their exposure doses are relatively well known and their dose responses in terms of cancer risk have also been thoroughly studied. An analysis has been made of erythrocyte glycophorin A (GPA) gene mutations in 1,226 atomic bomb survivors in Hiroshima and Nagasaki. The GPA mutation frequency (Mf) increased slightly but significantly with age at the time of measurement and with the number of cigarettes smoked. After adjustment for the effect of smoking, the Mf was significantly higher in males than in females and higher in Hiroshima than in Nagasaki. All of these characteristics of the background GPA Mf were in accord with those of solid tumor incidence obtained from an earlier epidemiological study of A-bomb survivors. Analysis of the dose effect on Mf revealed the doubling dose to be about 1.20 Sv and the minimum dose for detection of a significant increase to be about 0.24 Sv. No significant dose effect for difference in sex, city, or age at the time of bombing was observed. Interestingly, the doubling dose for the GPA Mf approximated that for solid cancer incidence (1.59 Sv). And the minimum dose for detection was not inconsistent with the data for solid cancer incidence. The dose effect was significantly higher in those diagnosed with cancer before or after measurement than in those without a history of cancer. These findings are consistent with the hypothesis that somatic mutations are the main cause of excess cancer risk from radiation exposure. PMID:8781371

  13. The children of atomic bomb survivors: A genetic study

    In this volume, many of the most important publications that appeared over the years on the survivors of Hiroshima and Nagasaki have been collected. Studies on health effects reached some important conclusions. Irradiation of gonads with moderately high dosage of ionizing irradiation as received by atomic bomb survivors did not lead to any statistically recognizable increase of health hazards among the survivors offspring. Constitutional aberrations and genetic variants recognizable at the protein level were not enhanced either

  15. Reevaluation of atomic bomb dose in Hiroshima and Nagasaki

    The Final Report Vol. 1 of the US-Japan Joint Reassessment of Atomic Bomb Radiation Dosimetry in Hiroshima and Nagasaki, which was carried out under the Radiation Effects Research Foundation, was released on July 8, 1987. Major contents of the Report are outlined here. The bombs dropped in Hiroshima and Nagasaki are respectively estimated to be equivalent to 22 kt and 12.5 kt of TNT. The number of leakage neutrons from the bombs was 1.07 x 1023 n/kt in Hiroshima and 1.65 x 1023 n/kt in Nagasaki while the number of leakage photons was 3.04 x 1021 γ/kt in Hiroshima and 3.79 x 1022 γ/kt in Nagasaki. The effects of the scattering at the ground surface and atmospheric humidity on the kerma in tissue in Hiroshima are shown. Investigation of the contributions of prompt and delayed neutrons and gamma rays to the kerma in tissue reveals that the dose of delayed gamma rays is increasingly greater than that of prompt gamma rays at points closer to the blast center. The soft tissue kerma values estimated from TL measurements made by various research institutes are compared to calculations. Measurements of neutron-induced radioactivity are also compared to calculations. Some model houses to be used for evaluation of the shielding performance of houses are proposed. Some applications of the Dosimetry System 1986 (DS86), a procedure for calculating the exposure dose of victims of the bombs developed in 1986 are also described. (Nogami, K.)

  16. Effect of L/D Ratio on Bomb Ricochet

    Full Text Available Intensive experimental work carried out, to study the effect of the length of a projectile on its ricochet behaviour has been reported. The work is pertinent for designing the bomb to be delivered by low altitude/high speed mode for destruction of runways. Scaled models have been used to conduct these studies and a relationship showing the variation of critical angle of no-ricochet with L/D ratio is evolved.

  17. Forensic Medicine: Age Written in Teeth by Nuclear Bomb Tests

    Establishing the age of individuals is an important step in identification and a frequent challenge in forensic medicine. This can be done with high precision up to adolescence by analysis of dentition, but establishing the age of adults has remained difficult. Here we show that measuring {sup 14}C from nuclear bomb tests in tooth enamel provides a sensitive way to establish when a person was born.

  19. Autopsy cases of hepatocellular carcinoma in atomic bomb survivors

    Since 1956, 388 autopsy cases of hepatocellular carcinoma (HCC) have been obtained at the Hiroshima Red Cross and A-Bomb Survivors Hospital, which consisted of those of proximately exposed 52 A-bomb survivors (mean age, 63.8 years), 105 distally exposed A-bomb survivors (mean age, 64.2 years), and the other 231 non-exposed patients (mean age, 60.6 years). Since 1985, the incidence of HCC tended to be higher in both proximately and distally exposed groups than the non-exposed group. There was no consistent tendency for the incidence of HCC by ages at autopsy and A-bombing. The incidence of liver cirrhosis was approximately 2 times higher in males than females in the non-exposed group, although no gender difference existed after 1981. In the exposed group, the incidence was similar in male and female groups. Approximately 90% of HCC patients had coexistent liver cirrhosis. Liver cirrhosis was associated with HCC in 50-60%. No significant differences in these incidences were observed between the exposed and non-exposed groups. The proportion of liver cirrhosis associated with HCC became constant in patients over the age of 40 in the non-exposed group. In the exposed group, on the other hand, the proportion reached the peak in those in their fifties and sixties. Survival time tended to be longer in the exposed group than the non-exposed group. The patients in the non-exposed group tended to have histologically atypical type and metastases, as compared with those in the exposed group. (N.K.)

  1. Investigation of lung cancer in atomic bomb survivors

    Fourty two cases of lung cancer in A-bomb survivors experienced between 1971 and 1975 were compared to non-exposure cases with lung cancer, and discussed. The mean age of A-bomb survivors with lung cancer was 68.7 year old, and that of control cases was 60 year old. The incidence ratio of male to female in the group was 4 : 1, and that of control group was 5 : 1. Occupation was one of the predisposing causes, but patients who had engaged in the occupation which was considered to predispose lung cancer were three. Among 39 patients with lung cancer whose smoking histories were clarified, 20.5 per cent was nonsmoker, and 69.3 per cent was heavy smoker. Among 39 patients whose cancer histories were clarified, 28.2 per cent of the patients had family history of cancer. Subjective symptoms of this disease were cough, sputum, bloody sputum and chest pain, and some had no symptoms. Seventeen cases (40.5 per cent) were detected in the physical examination for the A-bomb survivors. For the early detection of lung cancer in A-bomb survivors, patients with high risk should be selected to have received clearly established diagnosis. Histologically, squamous cell carcinoma was seen in many cases, following adenoma, and undifferenciated large cell carcinoma and small cell carcinoma. Disturbances in pulmonary functions were obstructive ventilation, high rate of residual air, lowered diffusions ability. Therapy was operation in stage I, chemotherapy and radiation therapy in stage II and stage III. (Kanao, N.)

  2. Radiation therapy among atomic bomb survivors, Hiroshima and Nagasaki

    In the continuing evaluations of atomic bomb survivors for late radiation effects, not only doses from the A-bombs but those from other radiation sources must be considered, for the latter may be concomitantly acting factors causing bias among these investigations. In the present study, among 73 Hiroshima and 22 Nagasaki Adult Health Study (AHS) subjects who reported receiving radiation therapy, from 1970 through 1979, the medical records of 72 and 20, respectively, were reviewed, and 41 Hiroshima and 14 Nagasaki subjects were confirmed to have received radiation therapy. The data obtained in the present study were pooled with those of the previous investigation on radiation therapy exposures of AHS subjects prior to 1970. A total of 190 subjects have been documented as receiving radiation therapy and their doses were estimated. Energies used in treatments and diseases treated are discussed. Malignancies developed subsequent to radiation therapy in seven cases; five after treatment for malignancies and two after treatment for benign diseases. Neoplasms of 12 AHS subjects may have been induced by earlier radiation therapy; 5 in the earlier study and 7 in the present one. These investigations underscore the need for continued documentation of exposures to ionizing radiation for medical reasons, especially from sources incurring relatively high doses. Bias in assessments of late radiation effects among A-bomb survivors can thus be avoided. (author)

  3. Dating human DNA with the 14C bomb peak

    In 1963 the limited nuclear test ban treaty stopped nuclear weapons testing in the atmosphere. By then the addition from bomb-produced 14C had doubled the 14C content of the atmosphere. Through the CO2 cycle this excess exchanged with the hydrosphere and biosphere leading to a rapidly decreasing 14C level in the atmosphere. Today we are almost back to the pre-nuclear level. As a consequence all people on Earth who lived during the second half of the 20th century were exposed to this rapidly changing 14C signal. A few years ago, a group at the Department of Cell and Molecular Biology of the Karolinska Institute in Stockholm started to use the 14C bomb peak signal in DNA to determine retrospectively the age of cells from various parts of the human body (brain, heart, fat). In a collaboration with this group, we have studied the age of olfactory bulb neurons in the human brain. For this investigation, 14C AMS measurements were developed at VERA for very small carbon samples in the range from 2 to 4 micrograms. In the presentation the general concept of 14C bomb peak dating of human DNA and several applications are discussed.

  4. Patenting the bomb: nuclear weapons, intellectual property, and technological control.

    Wellerstein, Alex

    2008-03-01

    During the course of the Manhattan Project, the U.S. government secretly attempted to acquire a monopoly on the patent rights for inventions used in the production of nuclear weapons and nuclear energy. The use of patents as a system of control, while common for more mundane technologies, would seem at first glance to conflict with the regimes of secrecy that have traditionally been associated with nuclear weapons. In explaining the origins and operations of the Manhattan Project patent system, though, this essay argues that the utilization of patents was an ad hoc attempt at legal control of the atomic bomb by Manhattan Project administrators, focused on the monopolistic aspects of the patent system and preexisting patent secrecy legislation. From the present perspective, using patents as a method of control for such weapons seems inadequate, if not unnecessary; but at the time, when the bomb was a new and essentially unregulated technology, patents played an important role in the thinking of project administrators concerned with meaningful postwar control of the bomb.

  5. Hemorrahgic diathesis of the inpatient in Hiroshima Atomic Bomb Hospital

    From the atomic bomb survivors who visited Hiroshima Atomic Bomb Hospital for a complaint of hemorrhagic diathesis, 15 patients who were required hospitalization were chosen for an evaluation of the hemorrhagic diathesis. 11 cases of them had vascular disorder and 4 thrombocyte abnormality, and there was no case of coagulation abnormality which may cause hemorrhage. A case of purpura angiopathica recently died from encephalomalacia, and its autopsy disclosed amiloidosis. This is very interesting because amiloidosis is a disease which systematically damages the blood vessels. Case I (in the case report) which had no serious morbid change except for cerebral and subarachnoid hemorrhage and had repeated episodes of extensive subcutaneous hemorrhage. Case 2 which was exposed 1.6 km apart from the epicenter at the age of 3 showed a gradual decrease of thrombocyte count from 210,000 to 40,000 during the course of 3 year, and died from cerebral hemorrhage at the age of 27. There still remain some doubt about the cause of this death. As this survey was done retrospectively, it was difficult to give an acurate diagnosis to each case. However, this result will suggest a general tendency of hemorrhagic diathesis in atomic bomb survivors. (Ueda, J.)

  6. Hyperparathyroidism among atomic bomb survivors in Hiroshima, 1986-88

    During the two-year period from August 1986 to July 1988, the prevalence of hyperparathyroidism (HPT) was determined among A-bomb survivors and unexposed control subjects in Hiroshima. The diagnosis of HPT was determined biochemically, based upon the presence of consistent hypercalcemia and elevated serum parathyroid hormone levels. Among a population of 4,675 individuals (1,527 males, 3,148 females), primary HPT was diagnosed in 22 (3 males, 19 females). Of these, 8 underwent surgery, of whom 6 had a single parathyroid adenoma and 2 had parathyroid hyperplasia. HPT was more prevalent among the A-bomb survivors who received higher radiation doses (p <.001 for linear trend). The prevalence rates predicted from the model were 0.204% (±0.094%) at 0 Gy and 0.893% (±0.237%) at 1 Gy. The background rate of HPT did not differ significantly by sex or by age at the time of the bombing, although the effect of radiation exposure was greater for individuals exposed at a younger age (p <.01).

  7. Neutron bomb. A clean weapon which destroys only life

    Mr. Konrad Luebbert, pastor, is the representative of the Christian peace movement. His contribution immediately originated from the recent peace movement and must be understood as a support of it. Today it is a matter of survival of total mankind. In view of further armament this is becoming more evident from day to day. In view of the neutron bomb it is exemplarily evident. Resistance must be offered to this new generation of nuclear weapons so that the development of armament is not completely getting out of control. The selection of documents is only very incomplete due to the limited space and cannot nearly describe the whole extent of the discussion, above all of the international protest movement which developed since the plans to produce the neutron bomb became known. Nevertheless, the selection gives a survey of typical expressions of views. This survey of documentary material is thought to be information and argumentation for all those who condemn the neutron bomb to be a 'perversion of human thinking' and jointly want to prevent its production and stationing.

  8. Profiles of non-cancer diseases in atomic bomb survivors

    This article summarizes the results of a recent study of atomic bomb radiation and non-cancer diseases in the AHS (Adult Health Study) population by the RERF (Radiation Effects Research Foundation) along with a general discussion of previous studies. Recent studies have demonstrated almost certainly that uterine myoma is more frequent among atomic bomb survivors. It cannot, at present, be concluded that uterine myoma is caused by radiation, because there are no reported studies of other exposed populations. Further analyses including the role of confounding factors as well as molecular approaches are needed to verify this radiation effect. The relationship between atomic bomb radiation exposure and hyperparathyroidism can now be said to have been established in view of the strong dose response, the agreement with results of studies of other populations, the high risk in the younger survivors, and the biological plausibility. Future studies by molecular approaches, etc., are needed to determine the pathogenic mechanism. Among other benign tumours, a dose response has been demonstrated for tumours of the thyroid, stomach and ovary. Although fewer studies have been conducted than for cancer, a clear association between radiation and various benign tumours is emerging. 79 refs, 5 figs, 1 tab

    1992-03-01

    Prognosis of pancreatic carcinoma in 28 Hiroshima A-bomb survivors was compared with that in background- and tumor size-matched non-exposed patients living in Hiroshima. A-bomb survivors consisted of 13 exposed within 2,000 m from the hypocenter, 12 who had entered the city within 3 days after A-bombing, and 3 not clarified in detail. Survival time was significantly prolonged when tumor resection or surgical internal fistula for obstructive jaundice was performed. The significant therapeutic factor was thus adjusted by using the Cox model to clarify the difference in cumulative survival rates between the exposed and non-exposed groups of pancreatic cancer patients. Median survival was 120 days in the exposed group and 186 days in the non-exposed group. The corresponding figures for 75% and 25% cumulative survival rates were 175 days and 75 days in the exposed group and 238 days and 120 days in the non-exposed group. Prognosis was worse in the exposed group than the non-exposed group. (N.K.).

    2005-01-05

    Rockfishes (Sebastes spp.) support one of the most economically important fisheries of the Pacific Northwest and it is essential for sustainable management that age estimation procedures be validated for these species. Atmospheric testing of thermonuclear devices during the 1950s and 1960s created a global radiocarbon ({sup 14}C) signal in the ocean environment that scientists have identified as a useful tracer and chronological marker in natural systems. In this study, we first demonstrated that fewer samples are necessary for age validation using the bomb-generated {sup 14}C signal by emphasizing the utility of the time-specific marker created by the initial rise of bomb-{sup 14}C. Second, the bomb-generated {sup 14}C signal retained in fish otoliths was used to validate the age and age estimation methodology of the quillback rockfish (Sebastes maliger) in the waters of southeast Alaska. Radiocarbon values from the first year's growth of quillback rockfish otoliths were plotted against estimated birth year producing a {sup 14}C time series spanning 1950 to 1985. The initial rise of bomb-{sup 14}C from pre-bomb levels ({approx} -90 {per_thousand}) occurred in 1959 {+-} 1 year and {sup 14}C levels rose relatively rapidly to peak {Delta}{sup 14}C values in 1967 (+105.4 {per_thousand}), with a subsequent declining trend through the end of the record in 1985 (+15.4 {per_thousand}). The agreement between the year of initial rise of {sup 14}C levels from the quillback rockfish record and the chronometer determined for the waters of southeast Alaska from yelloweye rockfish (S. ruberrimus) otoliths validated the ageing methodology for the quillback rockfish. The concordance of the entire quillback rockfish {sup 14}C record with the yelloweye rockfish time series demonstrated the effectiveness of this age validation technique, confirmed the longevity of the quillback rockfish up to a minimum of 43 years, and strongly supports higher age estimates of up to 90 years.

    Novel luminescent "nano-bombs" based on a self-assembled system of carbon-nanodots, termed supra-CDs, are developed. The luminescence of these luminescent "nano-bombs" depends strongly on water contact; they show weak emission in toluene and decompose in contact with water, resulting in strong photoluminescence. Paper coated with these "nano-bombs" is successfully applied for water-jet printing of luminescence patterns and the mapping of human sweat-pore patterns. PMID:25447963

    To assess the effects of atomic bomb radiation on the incidence of multiple primary cancers (MPC), we analyzed the association between the incidence of second primary cancers in survivors of the atomic bombing of Nagasaki, and exposure distance. The incidence rate (IR) of a second primary cancer was calculated and stratified by the distance from the hypocenter and age at the time of bombing for the years 1968 through 1999. The IR of the first primary cancer was also calculated and compared wi...

The Censo de Población y Vivienda (1991 and the Survey Ageing in Place (1998 are used. In general terms, old people live in old houses, as owners, not crowded but with lack of facilities. These people have been living for a long time in the same neighbourhood, an environment affected by the problems characteristic of big cities, and are integrated in the neighbour by means of activities requiring not to much physical or financial effort. Residential lacks affect mainly to that groups with social and economic vulnerability: female, lower income and educational level, worse health status,... So, two out ten aged people would move mainly due to the negative conditions of habitability, adaptation and facilities. Moreover, reasons for not moving are related to the force of habit, the memories, or consequence of age, bad health or less resources.

  17. The risk of ovarian cancer in atomic bomb survivors, Nagasaki city, Japan 1973-1987

    A population based study was conducted to evaluate the risk of ovarian cancer among female atomic bomb (A-bomb) survivors in Nagasaki City by using data from 1973 to 1987 of the Nagasaki Tumor Resistry. The incidence rate of ovarian cancer in the total female population in Nagasaki City decreased at ages 50-59, 60-69, and 70-79 with advancing the periods investigated (1973-1977, 1978-1982, and 1983-1987). A similar trend in the incidence rate was also observed in A-bomb survivors. The summarized risk ratio (SRR) of ovarian cancer was not significantly higher in A-bomb survivors; SRR: 1.30 (95% confidence interval of SRR: 0.64-2.68) in the survivors exposed to the A-bomb radiation within 2 km of the hypocenter, and 1.07 (0.78-1.46) in the total population of A-bomb survivors. There was also no difference in histologic type of ovarian cancer between A-bomb survivors and non-exposed persons. It should be noted, however, that the incidence rate at age 40-49 was higher in A-bomb survivors than in non-exposed persons during the all periods investigated. A follow-up study is, therefore, still necessary to evaluate the risk of ovarian cancer in A-bomb survivors in Nagasaki city. (author)

  18. A long-term cohort study of the atomic-bomb survivors

    The Atomic Bomb Casualty Commission (ABCC), the predecessor of the Radiation Effects Research Foundation (RERF), was established in 1947 to conduct long-term, comprehensive epidemiological and genetic studies of the atomic-bomb (A-bomb) survivors. Today this study still depends upon the voluntary cooperation of several tens of thousands of survivors of the bombings of Hiroshima and Nagasaki. An in-depth follow-up study of mortality in the study population of 120,000 persons, including A-bomb survivors and controls, has continued since 1950. The study of tumor incidence was initiated through record linkage with a tumor registry system in Hiroshima and Nagasaki in 1958. In the same year, biennial medical examinations of 20,000 individuals began. Follow-up studies also have been conducted on in-utero-exposed persons and first-generation offspring of the survivors. On the basis of these studies spanning nearly half a century, we know that the occurrence of leukemia and cancers associated with A-bomb radiation is higher than among the non-exposed. Among the A-bomb survivors, radiation cataracts, hyperparathyroidism, delayed growth and development, and chromosomal aberrations also occur more often. However, to date no evidence exists of genetic effects in the children of A-bomb survivors. It should be kept in mind that such study results could never be obtained without the cooperation of A-bomb survivors. (author). 53 refs

  19. Comments on the exposure distance as a factor of severity of A-bomb cataracts

    In the study of A-bomb disorders, it is important in decision of exposure dose to consider not only exposure distance from the hypocenter but also shelter factors, and 8 cases were reported as examples. Group 1 (4 cases) was exposed to A-bomb in the train 750 m east of the hypocenter, and group 2 (4 cases) was exposed in the concrete steel building 620 m east of the hypocenter. Age, exposure distance, exposure place, shelter condition, wounds, acute symptoms due to A-bomb exposure, radiation dose, condition of turbidity of the crystalline lens, effect of A-bomb on visual acuity of eight cases were listed in table. Group 1 was exposed to A-bomb at the place 130 m far from the place where group 2 was exposed, but the exposed dose of group 1 was equivalent to twice that of group 2. Acute symptoms due to A-bomb exposure, turbidity of the crystalline lens, and effect of A-bomb on visual acuity were by far stronger in group 1 than in group 2. It was stressed that physical history and treatment course of the patients with A-bomb cataract were enough to be important materials on the study of A-bomb disorders. (Serizawa, K.)

  20. Chronic thought suppression and posttraumatic symptoms: data from the Madrid March 11, 2004 terrorist attack.

    Vázquez, Carmelo; Hervás, Gonzalo; Pérez-Sales, Pau

    2008-12-01

    Although a considerable number of people either witnessed directly or in the mass media the traumatic scenes of the terrorist attack that took place on March 11th, 2004 in Madrid, only a fraction of Madrid citizens developed posttraumatic symptoms. In this study, posttraumatic stress-related symptoms, degree of exposure, coping strategies related to the attack, and chronic attempts to avoid intrusive thoughts (i.e., thought suppression) were assessed in a general population Madrid sample (N=503) 2-3 weeks after the attacks. Our results showed that participants with higher scores in chronic thought suppression exhibited higher levels of PTSD symptoms. Higher scores in chronic thought suppression also correlated positively with the use of avoidant coping strategies after the attacks. We discuss the possible common roots of avoidance of intrusive thoughts and avoidant coping strategies and the implications of this relationship for the emergence of stress-related symptoms as well as for public health policies.

  6. Spatial Hedonic Pricing Models for Testing the Adequacy of Acoustic Areas in Madrid, Spain

    José-María Montero

    2011-01-01

    Full Text Available Road traffic noise is one of the main concerns of large cities. Most of them have classified their territory in acoustic areas and have constructed strategic noise maps. From both sources we have elaborated seven types of acoustic neighbourhoods according to both their noise gap in regard to the legal standard and the percentage of population exposed to noise. A spatial Durbin model has been selected as the strategy that best models the impact of noise on housing prices. However, results for Madrid do not confirm the hedonic theory and indicate, as one of the possibilities, that the official acoustic areas in Madrid could be incorrectly designed.

  10. LOW-FREQUENCY (11 mHz) OSCILLATIONS IN H1743-322: A NEW CLASS OF BLACK HOLE QUASI-PERIODIC OSCILLATIONS?

    We report the discovery of quasi-periodic oscillations (QPOs) at ∼11 mHz in two RXTE and one Chandra observations of the black hole candidate H1743-322. The QPO is observed only at the beginning of the 2010 and 2011 outbursts at similar hard color and intensity, suggestive of an accretion state dependence for the QPO. Although its frequency appears to be correlated with X-ray intensity on timescales of a day, in successive outbursts eight months apart, we measure a QPO frequency that differs by less than ≈2.2 mHz while the intensity had changed significantly. We show that this ∼11 mHz QPO is different from the so-called Type C QPOs seen in black holes and that the mechanisms that produce the two flavors of variability are most probably independent. After comparing this QPO with other variability phenomena seen in accreting black holes and neutron stars, we conclude that it best resembles the so-called 1 Hz QPOs seen in dipping neutron star systems, although having a significantly lower (1-2 orders of magnitude) frequency. If confirmed, H1743-322 is the first black hole showing this type of variability. Given the unusual characteristics and the hard-state dependence of the ∼11 mHz QPO, we also speculate whether these oscillations could instead be related to the radio jets observed in H1743-322. A systematic search for this type of low-frequency QPOs in similar systems is needed to test this speculation. In any case, it remains unexplained why these QPOs have only been seen in the last two outbursts of H1743-322.

  11. 360° FILM BRINGS BOMBED CHURCH TO LIFE

    K. Kwiatek

    2012-09-01

    Full Text Available This paper explores how a computer-generated reconstruction of a church can be adapted to create a panoramic film that is presented in a panoramic viewer and also on a wrap-around projection system. It focuses on the fundamental principles of creating 360º films, not only in 3D modelling software, but also presents how to record 360º video using panoramic cameras inside the heritage site. These issues are explored in a case study of Charles Church in Plymouth, UK that was bombed in 1941 and has never been rebuilt. The generation of a 3D model of the bombed church started from the creation of five spherical panoramas and through the use of Autodesk ImageModeler software.

  12. The impact of the reassessment of A-bomb dosimetry

    This report examines the anticipated impact of the adoption by RERF of a new atomic bomb radiation dosimetry system to replace the revised tentative 1965 dosimetry system (T65DR). The current binational effort to reassess A-bomb dosimetry will eventually produce information about air doses and attenuation due to shielding by structures and body tissue. A method for computing individual survivors' total body surface exposure doses and organ doses from such data was developed, and a set of interim 1985 dosimetry (I85D) estimates was computed by this method using the data available to RERF in late 1984. Estimates of I85D total body surface exposure doses could be computed for 64,804 of 91,231 exposed survivors with T65DR dose estimates; following present plans, revised dose estimates may become available for an additional group of 10,000 to 12,000 exposed survivors. Mortality from leukemia and from all cancers except leukemia was examined in relation to I85D total body surface exposure doses (gamma plus neutron); parallel analyses using T65DR exposure doses were also conducted for the same set of survivors. Overall estimates of radiogenic excess risk based on I85D total body surface doses were about 50 % greater than those based on T65DR doses. Nonsignificant differences of only 3 % or less between the radiogenic excess risks for Hiroshima and Nagasaki survivors were observed in relation to I85D doses. Modification of the radiation dose response by sex, age at the time of the bombing, or time since exposure was qualitatively similar for I85D and T65DR. For both leukemia and nonleukemic cancer mortality, the radiogenic excess risk was found to increase as a linear function of I85D total body surface dose; significantly poorer fits were obtained with pure quadratic dose-response functions, while linear-quadratic dose responses did not provide significantly better fits.

  13. 360° Film Brings Bombed Church to Life

    Kwiatek, K.

    2011-09-01

    This paper explores how a computer-generated reconstruction of a church can be adapted to create a panoramic film that is presented in a panoramic viewer and also on a wrap-around projection system. It focuses on the fundamental principles of creating 360º films, not only in 3D modelling software, but also presents how to record 360º video using panoramic cameras inside the heritage site. These issues are explored in a case study of Charles Church in Plymouth, UK that was bombed in 1941 and has never been rebuilt. The generation of a 3D model of the bombed church started from the creation of five spherical panoramas and through the use of Autodesk ImageModeler software. The processed files were imported and merged together in Autodesk 3ds Max where a visualisation of the ruin was produced. A number of historical images were found and this collection enabled the process of a virtual reconstruction of the site. The aspect of merging two still or two video panoramas (one from 3D modelling software, the other one recorded on the site) from the same locations or with the same trajectories is also discussed. The prototype of 360º non-linear film tells a narrative of a wartime wedding that occurred in this church. The film was presented on two 360º screens where members of the audience could make decisions on whether to continue the ceremony or whether to run away when the bombing of the church starts. 3D modelling software made this possible to render a number of different alternati ves (360º images and 360º video). Immersive environments empower the visitor to imagine the building before it was destroyed.

  14. Defective structure and conductivity mechanism of solid electrolytes based on M62M25O11 (M2 - Sr, Ba; M5 - Nb, Ta)

    Mechanism of Sr6Ta2O11 and Sr6Nb2O11 base solid solution formation is studied, and power transfer is investigated for definition of defective structure of tantalates and niobates of alkali-earth metals as well as allied compound oxides. Formation of Sr6M2O11 (M-Nb, Ta) base perovskite-like solid solutions is shown to take place by M5+ ion substitution for Sr2+ ions with simultaneous filling the structural vacancies of oxygen that results in variation of the value of conductivity by oxygen with the composition of solutions. A process of defect formation is considered

  15. Health status of atomic bomb survivors in South Korea, 3

    405 atomic bomb survivors, 223 men and 182 women, in Hap-cheon Gun of Kyeong Sang Nam Do in South Korea were investigated from 1973 to 1977. Diseases with chronological change, sex, age, and conditions at exposure were listed. Infections, tuberculosis, and diabetes mellitus decreased every year, whereas diseases of the respiratory organs, bone, muscle, and connective tissue increased. Only burns showed the relationship to the exposure level. The diseases of the survivors in South Korea were compared with those in Hiroshima. However, due to marked differences of socioeconomical conditions, statistical comparison was difficult. (Nakanishi, T.)

    Yokota, Ken-Ichi; Mine, Mariko; Honda, Sumihisa; Tomonaga, Masao

    2005-01-01

    To elucidate the association between epilation and cancer mortality in Nagasaki atomic bomb survivors, cancer mortality was determined for a total of 9,356 survivors (3,591 males and 5,765 females) from 1 January 1970 to 31 December 1997. The subjects included individuals other than those in the Life Span Study (LSS) cohort of ABCC-RERF. Information on acute injury was obtained from a survey that was conducted at the time of application for a health handbook. The association between epilation...

  17. Mortality of atomic bomb survivors predicted from laboratory animals

    Carnes, Bruce A.; Grahn, Douglas; Hoel, David

    2003-01-01

    Exposure, pathology and mortality data for mice, dogs and humans were examined to determine whether accurate interspecies predictions of radiation-induced mortality could be achieved. The analyses revealed that (1) days of life lost per unit dose can be estimated for a species even without information on radiation effects in that species, and (2) accurate predictions of age-specific radiation-induced mortality in beagles and the atomic bomb survivors can be obtained from a dose-response model for comparably exposed mice. These findings illustrate the value of comparative mortality analyses and the relevance of animal data to the study of human health effects.

    Satoh, C; Takahashi, N.; Asakawa, J; Kodaira, M; Kuick, R; Hanash, S M; Neel, J V

    1996-01-01

    Studies are under way for the detection of potential genetic effects of atomic bomb radiation at the DNA level in the children of survivors. In a pilot study, we have examined six minisatellites and five microsatellites in DNA derived from 100 families including 124 children. We detected a total of 28 mutations in three minisatellite loci. The mean mutation rates per locus per gamete in the six minisatellite loci were 1.5% for 65 exposed gametes for which mean parental gonadal dose was 1.9 Sv...

  19. Two cases of giant parathyroid adenoma in atomic bomb survivors

    In a study of parathyroid tumor among autopsy cases at RERF in Hiroshima, 16 cases of parathyroid adenoma were detected among 4,136 autopsies during 1961-77. Of these, two cases were giant adenoma (5 cm in diameter) accompanied by hyperparathyroidism. Both cases were atomic bomb survivors from Hiroshima. One was exposed to 55 rad at age 51 and died at age 71, and the other was exposed to 28 rad at age 45 and died at age 71. These two cases will be reported together with a review of the literature on parathyroid tumors developed following irradiation on the head and neck. (author)

  20. Fast neutron fluence of the Hiroshima atomic bomb

    The fast neutron fluence of the Hiroshima atomic bomb was estimated by measuring radioactive nuclides produced by the fast neutron reaction in various materials. The early measurements were carried out for 32P. The new data obtained for 63Ni produced by the 63Cu(n, p)63Ni reaction were shown. The data for 63Ni were obtained by both the accelerator mass spectrometry and the low background beta-ray measurement. The data for the fast neutron fluence are consistent with the values calculated by a new Dosimetry System 2002 (DS02). (author)

  1. Some thoughts on Hiroshima: 50 years after the bomb

    Commemorating the fiftieth anniversary of Hiroshima, this paper covers three issues: Personal experience, concluding that the bomb was an extraordinary cruel weapon beyond imagination, Japanese experience, i.e. Japanese attitude against nuclear weapons and the actions to be undertaken in order to achieve nuclear-weapon-free world. The support of Non-proliferation Treaty, as well as the support of the protest against any kind of nuclear weapon experiments should be related to the understanding of the cause of the events against which one is protesting. The radical therapy would be the removal of the cause, i.e. the striking discrepancy of nuclear armaments

  2. Review of dosimetry for the atomic bomb survivors

    This paper summarizes and discusses results of some 1980-1981 studies of neutron and γ-ray exposure to the atomic bomb survivors by W.E. Loewe and E. Mendelsohn of the Lawrence Livermore National Laboratory, D.C. Kaul and W.H. Scott of Science Applications, Inc., and J.V. Pace of the Oak Ridge National Laboratory. Some other special studies which are now underway to complete the review will also be discussed. The expert assistance of others in these special studies is being supported in part by the US Department of Energy and in part by the US Defense Nuclear Agency

  3. Tendency of socio-psychological aftereffects on aged survivors in Hiroshima A-bomb survivors home

    Psychosomatic status at the time of A-bomb explosion, behavior and impression immediately after the explosion, aftereffects on life, and mental changes were sought through interview for 80 aged survivors in Hiroshima A-bomb survivor home by psychiatric social workers. (Namekawa, K.)

  4. Epidemiologic study of skin cancer in Nagasaki atomic-bomb survivors

    This study was designed to investigate the correlation between the incidence of skin cancer and exposure distance in Nagasaki A-bomb survivors. When 140 A-bomb survivors, collected from 31 medical facilities in Nagasaki and its surrounding areas, were analyzed using logistic regression model based on the data of 66,276 A-bomb survivors, the incidence of skin cancer was found to be significantly lower in A-bomb survivors exposed farther from the hypocenter. This was also noted when confining to either men or women. Among 25,942 A-bomb survivors, available using DS85 dosimetry system, in the RERF-Life Span Study sample and RERF-Adult Health Study sample (1958-1985), 47 A-bomb survivors were found to have skin cancer. For them, higher incidence of skin cancer was associated with larger radiation doses. Dose-response relationship for skin cancer was linear. Twenty five of the 47 A-bomb survivors (53%) histologically had basal cell carcinoma. Since 1975, an increased rate in the incidence of skin cancer has been noticeable in A-bomb survivors exposed at ≤2,500 m than those exposed at ≥3,000 m. The number of excess cases of skin cancer was found to have been steadily increased since 1958. (N.K.)

  5. Reopening of the survey, study and medical care of atomic bomb victims

    Research on atomic bomb casuality of the results by Japanese scientists were greatly restricted during the Occupation period. Conditions improved in 1951 when the San Francisco Peace Treaty was signed. After the conclusion of the Treaty, there were various movements in the fields of the survey, study and medical care of atomic bomb victims. The Science Council of Japan formed the Atomic Bomb Casuality Research Group, which was supported by scientific research funds from the Ministry of Education in 1952. The group had the hope of taking place of Atomic Bomb Casuality Commission (ABCC) which was established by USA. But the study of the group was supported by ABCC. The Hiroshima Atomic Bomb Casuality Council was formed in January 1953 with the cooperation of Hiroshima City and its assembly, medical association of the city, and other groups. In Nagasaki, this Council was formed in May this year. These movement led the constitution of the Atomic Bomb Aftereffects Research Council in the National Institute of Health on November 1953. Hiroshima and Nagasaki City, and their Assemblies started their appeals of medical care for atomic bomb victims from the end of 1951. The same appeals were made by the press and welfare group in 1953. In the period from the end of 1951 to 1953, the way for the Medical Care Law was paved by various groups. But the enactment of the law needed the social power of the nationalwide movement against A- and H-bomb. (author)

  6. A Confusion of Signals: James Franck, the Chicago Scientists and Early Efforts to Stop the Bomb

    If the scientists working on the Manhattan Project had realized the consequences of the atomic bomb earlier, formulated their recommendations more precisely, and approached the statesmen in time, American policy on use and control of the bomb might well have been different. (Author/BT)

  7. Mental health conditions in Korean atomic bomb survivors. A survey in Seoul

    More than 60 years have elapsed since the atomic bombings to Hiroshima and Nagasaki, and since all of the atomic bomb survivors have become old, the importance of caring their mental health has become increasing in Japan. Although approximately 70% of overseas atomic bomb are living in Korea, there have been quite few studies on their mental health. The objectives of the present study were to elucidate whether the mental health conditions of atomic bomb survivor in Korea are similar to those in Japan. The subjects were 181 Korean atomic bomb survivors living in Korea (cases) and 209 outpatients of a hospital in Seoul who were not exposed to atomic bombs (controls). Interviewers administered them at the hospital a questionnaire with Impact of Event Scale-Revised, General Health Questionnaire 12 (GHQ-12), Korean version of short form Geriatric Depression Scale and the K scale of the Minnesota Multiphasic Personality Inventory. Excluding subjects with incomplete responses we analyzed 162 cases and 189 controls. The proportion of subjects with high score of GHQ-12 (≥4) was significantly higher in cases (78/162 or 48.1%) than in controls (42/189 or 22.2%) (p<0.0001, Fisher's exact test). The present results, though preliminary, indicate that atomic bomb survivors in Korea have also mental health problems similar to those observed in Japanese atomic bomb survivors, indicating the necessity of a larger study.

  8. One minute after the detonation of the atomic bomb: the erased effects of residual radiation.

    Takahashi, Hiroko

    2009-01-01

    The U.S. Government's official narrative denies the effects of residual radiation which appeared one minute after the atomic bomb detonations in Hiroshima and Nagasaki. This paper explores declassified documents from the U.S. Atomic Energy Commission, the Atomic Bomb Casualties Commission, and others and shows that these documents actually suggested the existence of serious effects from residual radiation.

    2013-01-01

    Atomic bomb (A-bomb) radiation is associated with cardiovascular disease (CVD) and metabolic CVD risk factors. Chronic kidney disease (CKD) is also known to be a risk factor for CVD and little is known whether CKD is associated with A-bomb radiation. To examine whether CKD is associated with CVD risk factors or with A-bomb radiation in A-bomb survivors, we classified renal dysfunction in 1,040 A-bomb survivors who were examined in 2004-2007 as normal [n = 121; estimated glomerular filtration rate (eGFR) ≥ 90 ml/min/1.73 m(2)]; mild (n = 686; eGFR 60-89 ml/min/1.73 m(2)); moderate (n = 217; eGFR 30-59 ml/min/1.73 m(2)); or severe (n = 16; eGFR bomb radiation. Hypertension [odds ratio (OR), 1.57; 95% confidence interval (CI), 1.12-2.20, P = 0.009]; DM (OR, 1.79; 95% CI, 1.23-2.61, P = 0.002); hyperlipidemia (OR, 1.55; 95% CI, 1.12-2.14, P = 0.008); and MetS (OR, 1.86; 95% CI, 1.32-2.63, P bomb survivors.

    Novel luminescent "nano-bombs" based on a self-assembled system of carbon-nanodots, termed supra-CDs, are developed. The luminescence of these luminescent "nano-bombs" depends strongly on water contact; they show weak emission in toluene and decompose in contact with water, resulting in strong photo

  14. Game of thrown bombs in 3D: using high speed cameras and photogrammetry techniques to reconstruct bomb trajectories at Stromboli (Italy)

    Large juvenile bombs and lithic clasts, produced and ejected during explosive volcanic eruptions, follow ballistic trajectories. Of particular interest are: 1) the determination of ejection velocity and launch angle, which give insights into shallow conduit conditions and geometry; 2) particle trajectories, with an eye on trajectory evolution caused by collisions between bombs, as well as the interaction between bombs and ash/gas plumes; and 3) the computation of the final emplacement of bomb-sized clasts, which is important for hazard assessment and risk management. Ground-based imagery from a single camera only allows the reconstruction of bomb trajectories in a plan perpendicular to the line of sight, which may lead to underestimation of bomb velocities and does not allow the directionality of the ejections to be studied. To overcome this limitation, we adapted photogrammetry techniques to reconstruct 3D bomb trajectories from two or three synchronized high-speed video cameras. In particular, we modified existing algorithms to consider the errors that may arise from the very high velocity of the particles and the impossibility of measuring tie points close to the scene. Our method was tested during two field campaigns at Stromboli. In 2014, two high-speed cameras with a 500 Hz frame rate and a ~2 cm resolution were set up ~350m from the crater, 10° apart and synchronized. The experiment was repeated with similar parameters in 2015, but using three high-speed cameras in order to significantly reduce uncertainties and allow their estimation. Trajectory analyses for tens of bombs at various times allowed for the identification of shifts in the mean directivity and dispersal angle of the jets during the explosions. These time evolutions are also visible on the permanent video-camera monitoring system, demonstrating the applicability of our method to all kinds of explosive volcanoes.

  6. Study on the multiple cancer in A-bomb survivors

    Autopsy data from cohort studies performed on A-bomb victims revealed that the incidence rate of multiple cancer was 7.8% (193 of 2,472 cancer A-bomb victims), being higher than that (5.8%) found from the tumor registry in Hiroshima and Nagasaki. Multiple cancer occurred more frequently in women than in men in both Nagasaki and Hiroshima. The incidence of multiple cancer was 1.5 times higher in the victims exposed to more than 100 rad (Vsub(+) group) than in those exposed to less than one rad (V0 group), suggesting that there might be dose-response relationship, although this was not statistically significant between the exposed groups. According to the organs, relative risk ratio of developing cancer in the Vsub(+) group to that in the V0 group was high in the colon and rectum, bladder, lungs, and testes in men; in the thyroid gland, lungs, colon and rectum, bladder, and breast in women, although no statistically significant differences were observed between the groups. This was suggestive of cancer that arises frequently in the lungs of men in the Vsub(+) group. Occult cancer of the thyroid gland and testes was also discussed in relation to the incidence of multiple cancer. (Namekawa, K.)

  7. Proliferative and nonproliferative breast disease in atomic-bomb survivors

    The risk of female breast cancer in association with radiation exposure is well established, on the basis of follow-up studies of the atomic-bomb survivors and other exposed populations. This association is especially strong for women exposed before age 20 yr and appears to be much weaker among women exposed after age 40 yr. In this study, breast-tissue autopsy samples from high-dose and low-dose individuals in the Radiation Effects Research Foundation Life Span Study sample were examined in detail to determine whether nonproliferative or proliferative breast lesions are associated with radiation exposure. The results suggest that proliferative disease in general and atypical hyperplasia in particular are associated with radiation exposure and that the risk is strongest for subjects who were ages 40-49 yr at the time of the bombings. It is hypothesized that this finding may be related to the age dependence of radiation-induced breast cancer, in the sense that potential cancers reflecting early-stage changes induced at these ages by radiation exposure may receive too little hormonal promotion to progress to frank cancers.

  8. Bonebrake Theological Seminary - Most Secret A-Bomb Project Site

    Sopka, Katherine R.; Sopka, Elisabeth M.

    2004-05-01

    In late 1943, a small number of nuclear scientists was urgently assembled in Dayton, Ohio by the U.S. Army Manhattan District Engineers and Monsanto Chemical Company Research Division to set up a top secret research project essential to counteract the German atomic bomb threat. The site chosen was an old stone building built in 1879 by the United Brethren Church in a residential area known locally as the Bonebrake Seminary. Centered on a sizeable open plot, the austere three story building was surrounded by a tall cyclone fence with a narrow gate and a minimal guard post - nothing revealed the site's intense research activity then or even in the post-WWII Cold War period. Bonebrake scientists would produce the highly radioactive polonium sources for the plutonium (Pu-239) bomb igniter used in August over Nagasaki just before the end of WWII against Japan. The existence of Bonebrake and its research/production work remained classified top secret throughout the Cold War. Only in recent times can any reference be found even to the existence of this project (unlike , for example, Los Alamos or Oak Ridge) and few, if any details, have ever been published. The primary source of information for this paper is Dr. John J. Sopka who was recruited from Princeton University by the Manhattan District in 1943 as physicist for this project.

  9. Bomb radiocarbon in annual tree rings from Thailand and Australia

    We have examined the atmospheric 14C excess in the tropics and the southern hemisphere temperate region in the bomb pulse period, using two sets of cross-dated tree rings. One set was from a medium-sized three-leaf pine (Pinus kesiya) grown in northwestern Thailand and the other was from a Huon pine (Lagarostrobos franklinii) grown in northwestern Tasmania, Australia. A total of 48 annual tree rings (24 pairs) from 1952 to 1975 AD were pretreated to alpha-cellulose, combusted to CO2 and converted to graphite for 14C measurement in the tandem accelerator at ANSTO. Excellent agreement was found between our measured 14C data from tree rings and atmospheric 14C records at similar latitudes. A large depletion of atmospheric 14C for Thailand in 1953-1954 AD was observed. This might be due to a combination of the Suess effect and upwelling in the tropical Indian Ocean. The results also showed the rise and decay of bomb 14C peaks from north to south with a time delay of about 1.5 yr, and the effects of minor atmospheric nuclear tests in the late 1960s and early 1970s. A delay of at least one month for 14C in tree cellulose of Huon pine compared with that in the atmosphere was also found

  10. Radiation and cancer risk in atomic-bomb survivors.

    Kodama, K; Ozasa, K; Okubo, T

    2012-03-01

    With the aim of accurately assessing the effects of radiation exposure in the Japanese atomic-bomb survivors, the Radiation Effects Research Foundation has, over several decades, conducted studies of the Life Span Study (LSS) cohort, comprising 93 000 atomic-bomb survivors and 27 000 controls. Solid cancer: the recent report on solid cancer incidence found that at age 70 years following exposure at age 30 years, solid cancer rates increase by about 35%  Gy(-1) for men and 58% Gy(-1) for women. Age-at-exposure is an important risk modifier. In the case of lung cancer, cigarette smoking has been found to be an important risk modifier. Radiation has similar effects on first-primary and second-primary cancer risks. Finally, radiation-associated increases in cancer rates appear to persist throughout life. Leukaemia: the recent report on leukaemia mortality suggests that radiation effects on leukaemia mortality persisted for more than 50 years. Moreover, significant dose-response for myelodysplastic syndrome was observed in Nagasaki LSS members even 40-60 years after radiation exposure. Future perspective: given the continuing solid cancer increase in the survivor population, the LSS will likely continue to provide important new information on radiation exposure and solid cancer risks for another 15-20 years, especially for those exposed at a young age.

  11. Axial length of atomic bomb survivors in Nagasaki

    We reviewed a series of 778 patients who had cataract surgery during the past 4 years at the Nagasaki Atomic Bomb Memorial Hospital. We evaluated the history of exposure to radiation by atomic bomb in 1945, axial length and state of refraction. All were born before 1945. The series comprised 263 males and 515 females. Their ages averaged 76.5±8.6 years. History of exposure to radiation was present in 356 patients. The remaining 422 patients served as control. There was no difference in the type of cataract between the two groups. High myopia was present in 11 irradiated patients (3.2%) and in 24 patients in the control group (6.0%). The difference was not significant (p=0.083). There was no high myopia among 24 patients who were aged 18 years or less at the time of radiation and who were within 2 km from the epicenter. No difference was present regarding the axial length between the two groups or between both sexes. The present result is not definitive because ''irradiated group'' would include those with little or no exposure and because precise data has not been available about the dosis of radiation.

  12. Biochemical genetics study of children of atomic bomb survivors

    In order to investigate genetic effect of radiation, especially the rate of mutation, the presence of protein variants in plasma and blood cells of children (F1 generation) of A-bomb survivors was examined. Twenty four kinds of protein consisting of 6 serum proteins and 18 hemoglobin, sampled from 2,800 children have been studied to data by using starch gel electrophoresis. Variants were detected in 13 kinds of proteins in 91 samples and among which the variants were observed often in transferrin, phosphoglucomutase and phosphohexose isomerase. To know whether detected variant types were induced by mutation, 54 cases of parents were tested. Results indicated that same variant types were observed in either of their parents. From these findings, it was confirmed that the variation is genetic and was not related to A-bomb radiation to their parents. Though the incidence of variant types was different in Hiroshima and Nagasaki, The number of samples, is not big enough to conclude it to be regional difference. (Iwagami, H.)

  13. Neutron bomb and conventional weapons of mass destruction

    The pros and cons of developing and producing neutron bombs are reviewed in the historical context of the lethality and destructive power of both conventional and nuclear weapons. Response from the arms-control community has generally been favorable toward the neutron bomb on the grounds that it would be an increased deterrent and would reduce reliance on tactical nuclear weapons. The validity of this position is questioned and it is pointed out that countries are now buying both new tactical nuclear and new conventional weapons as the destructive gap between the two types of weapons gets smaller. A qualitative form of arms limitation could be more effective than the present step-by-step disarmament strategy. Some groundwork has been done on an international update of the laws of war as a result of public pressure and antipathy toward anti-personnel weapons. The public response points up the need to expand our traditional forms of negotiating to incorporate the concepts of both security politics and humanitarian precepts

  14. Genetic radiation effects of Hiroshima and Nagasaki atomic bombs

    Srsen, S. (Komenskeho Univ., Bratislava (Czechoslovakia). Lekarska Fakulta)

    1984-05-01

    A group of researchers examined persons who had survived the Hiroshima and Nagasaki bombs and were irradiated and their progeny with the aim of getting an idea of the genetic effects of these explosions. Teratogenic effects are not discussed. In the lymphocytes of the peripheral blood of persons who had been exposed to high dose irradiation the researchers found a significant increase in chromosomal aberrations by conventional and more recent methods of chromosomal analysis. In parents who had survived the atomic holocaust there were no significant deviations as against the rest of the population in still births, neonatal defects, infant mortality, and mortality of first generation progeny, in neonate weight, the sex ratio, increased occurence of leukosis and chromosomal aberrations in their children. These negative findings in the first generation do not signify that there is no danger from atomic bomb blasts for human kind. They only indicate that the effects of radiation were too small to be found by routine methods or that the methods used were not suitable.

  16. Cytogenetic study of the offspring of atomic-bomb survivors

    Cytogenetic changes by exposure was discussed based on the data in United Nations Scientific Committee on Effects of Atomic Radiation (UNSCEAR, 1972) with mice and author's investigation on children of the atomic-bomb survivors. According to the experiment with mice reported in the UNSCEAR, the incidence of translocation in the spermatogonium increased in accordance with increased doses of neutron, x-ray and γ-ray irradiation, and decreased after a certain amount of doses, the peaks being 100 rad in neutron irradiation, 700 rad in x-ray and γ-ray irradiation. Such decreased of spermatogonium possessing translocation in itself indicated the fact that these cells might be naturally selected under the irradiation with high amount of dose. As the result, manifested abnormality in the first spermatocyte decreased. The investigation on the children of atomic-bomb survivors was done in two groups; a group of children whose parents were non-exposed or exposed below 1 rad of exposure and a group of children whose parent or both parents were exposed above 1 rad of exposure. The results were compared to the data on the newborn groups. The incidence of aberration in the number of the chromosomes was slightly higher in the exposed group than in the non-exposed group, however, there were no significant differences between them. It might be because unbalanced type abnormality was naturally selected by abortion and balanced type abnormality wouldn't manifested. Further abnormality would be selected naturally either.

  17. The bomb, the dark side of the nuclear world

    The reality of the nuclear world can be summarized in few words: a world arsenal of 26000 bombs, enough uranium and plutonium and the know-how to make much more, multiple non-proliferation and weapons limitation treaties which have troubles regulating the diffusion of this technology, indelible environmental and sanitary marks left by 2059 tests, governments secretly wishing to assume this supreme power attribute, a black market, spies and dealers, but also: opponents, political leaders, local representatives and non-governmental organizations who militate for a nuclear weapon-free world. However, this burning question paradoxically remains obscure to citizens and its obscure aspect is relayed by media and politicians. This book aims at decoding the wheels of the international nuclear weapons situation: from the five official nuclear powers to the proliferation actors, from the defense policies to the risks of accidents and the stakes of disarmament, from the bomb fabrication to its devastating effects. It shows how this ultimate weapon has durably pervaded the defense policies and strategies of countries who own it, and how difficult it will be to reconsider this situation

  18. Radiation and cancer risk in atomic-bomb survivors

    With the aim of accurately assessing the effects of radiation exposure in the Japanese atomic-bomb survivors, the Radiation Effects Research Foundation has, over several decades, conducted studies of the Life Span Study (LSS) cohort, comprising 93 000 atomic-bomb survivors and 27 000 controls. Solid cancer: the recent report on solid cancer incidence found that at age 70 years following exposure at age 30 years, solid cancer rates increase by about 35% Gy−1 for men and 58% Gy−1 for women. Age-at-exposure is an important risk modifier. In the case of lung cancer, cigarette smoking has been found to be an important risk modifier. Radiation has similar effects on first-primary and second-primary cancer risks. Finally, radiation-associated increases in cancer rates appear to persist throughout life. Leukaemia: the recent report on leukaemia mortality suggests that radiation effects on leukaemia mortality persisted for more than 50 years. Moreover, significant dose–response for myelodysplastic syndrome was observed in Nagasaki LSS members even 40–60 years after radiation exposure. Future perspective: given the continuing solid cancer increase in the survivor population, the LSS will likely continue to provide important new information on radiation exposure and solid cancer risks for another 15–20 years, especially for those exposed at a young age.

  20. Myth-building: The open-quotes Islamicclose quotes bomb

    The open-quotes Islamic Bombclose quotes is roughly understood to be a nuclear weapon aquired for broad ideological reasons--a weapon that supposedly belongs to the Muslim ummah or community and, as such, is the ultimate expression of Islamic solidarity. Concern about the Islamic bomb is at the heart of the intense effort to prevent the spread of nuclear weapons to Muslim countries. The official justification is a general one: proliferation must be curbed globally. But unofficially, the Islamic bomb gets special attention. The reasons behind this special attention are described in this article. The reasons include fear of terrorism, of a jihad willing to indiscriminately use nuclear weapons in hope of a reward in the Hereafter, and of the transfer of nuclear arms from nuclear to non-nuclear Muslim countries in times of crisis. Possibilities for controlling the proliferation of nuclear weapons in Muslim countries are addressed. Reasons are cited as to why various Muslim countries wish to acquire nuclear weapons

  1. Sociological and socio-psycho-historical problems of A-bomb exposed twin

    The atomic bombing of Hiroshima brought many casualities on human society, and collapsed human communities. The purpose of this study is to make mainly on pairs of monozygotic twins one of whom was exposed and the other was not, or both of whom were exposed, a general socio-psycho-historical investigations through a twin control study to find whether the bombing, which can be considered to cause major environmental changes, has had any psychological effects on the individuals. Due to the limited sample of atomic bomb exposed twins, in numbers available for study, it is necessary to have an understanding for their condions of the living and identity they have developed from the numerous mental stress they suffered, and rapid socio-cultural changes they experienced, including for changes in life from birth until the atomic bombing and aftermath of the disaster. As the result of this study, by depth interview, projective psychological research and research on socio-psycho-history of exposed twin and the nonexposed before the A-bomb and aftermath of disaster, the following were obtained: a) Although at the age of four and eight they exposed, they still keep it in clear memory of the damage and suffering in the minds. b) The damage and suffereng of the family who belonged were relatively small, the effects of their psychological sufferings continued even after these thirtyseven years. c) In the aftermath of the A-bomb disaster, the psychological bond showed strengthen through crises and following social distress. d) During the long period since the bombing, those who did not experienced A-bombing, have shown high degree of support and co-operation on their familial and social role to their counterpart. e) Even though their social or medical effects of A-bombing are relatively limited, if their spouse or close relative suffer psychological stress caused by A-bomb, they too suffer from their similar experiences.

  5. Statistical studies on cause of death among a-bomb survivors from 1970 to 1976 in Nagasaki City

    The death rate from malignant neoplasms in a-bomb survivors was higher than that in Japan through the whole period from 1970 to 1976. The death rate from malignant neoplasms was also high in a-bomb survivors in their thirties and fortieth exposed to a-bomb near the hypocenter. Seven thousand, five hundred and twenty-eight a-bomb survivors investigated this time were quivalent to 90% of all 8,334 a-bomb survivors who died during the period from 1970 to 1976. Therefore, the result obtained from this investigation seemed to indicate the cause of death correctly. Remaining 10% are now under investigation. (Tsunoda, M.)

  8. Accounting for neutron exposure in the Japanese atomic bomb survivors.

    Cullings, Harry M; Pierce, Donald A; Kellerer, Albrecht M

    2014-12-01

    The Japanese atomic bomb survivors that were directly exposed to both γ rays and neutrons have been followed by the Radiation Effects Research Foundation (RERF). The estimation of the γ-ray risks requires some adjustment for the greater biological effect of the neutrons per unit dose. Because the small neutron doses and the predominant γ-ray doses are highly correlated, the neutron relative biological effectiveness (RBE) cannot be reliably estimated from the survivors' data and information from radiobiology must be invoked. As data became available on neutron doses, RERF has used a constant neutron RBE value of 10, even though radiobiological studies indicate that the RBE values appear to have considerably larger values at low doses. The approximation RBE = 10 assumes that if the RBE is variable it takes roughly this value in the range of total dose most relevant for linear risk estimation, namely about 1 Gy. We consider some possible RBE functions to explain the correct use and the impact of a dose-dependent RBE. However, we do not advocate any particular choice or even that a variable RBE be employed. Rather we show that the assumed neutron RBE, within a wide range of choices, is far less important to the outcome of risk assessment of the RERF data than generally believed. Some of these misperceptions have been related to the consideration of variable RBE functions, and without due attention to the fact that in the case of the A-bomb survivors' data, the mixed field of neutrons and γ rays must be considered. Therefore, the RBE value of neutrons is much lower than the RBE in pure neutron fields that are used in radiobiological experiments. Thus, applying the pure neutron field RBE to the mixed-field A-bomb radiation can lead to an overestimation of the actual neutron RBE for moderate total dose levels of 1 Gy by a factor of more than four. While in a pure neutron exposure the RBE depends on the neutron dose, in the mixed field it depends on both components of

  9. Outline on populations of Nagasaki A-bomb survivors and sex ratio in their children

    On the basis of file delivered together with A-bomb surrivor's health Cards in Nagasaki, statistical management was performed on a mass of A-bomb survivors. The number of A-bomb survivors in a mass was 97,032. A family investigation by census registration was performed on 2,547 of A-bomb survivor group (the distance from the center of explosion recorded on cards was within 1.5 km) and 2,791 of its control group. As to 2,547 of A-bomb survivor group, each exposure place was determined, the distance from the center of explosion was measured again, and exposure dose was presumed. The mean exposure dose of A-bomb survivor group was 577 rad in male, and 681 rad in female. By adding A-bomb survivor group to the control group, 4,452 pairs of marriage were confirmed by census registration, and the number of their children was 10,073. With respect to changes of sex ratio, in case of exposed mother, it was expected theoretically that the number of male would decrease together with an decrease of dose, but an opposite change was recognized in a result of the investigation. A result in case of exposed father showed an increase of the male number although not significantly and a change towards the expected direction. (Tsunoda, M.)

  10. Effects of radiation on the incidence of prostate cancer among Nagasaki atomic bomb survivors.

    Kondo, Hisayoshi; Soda, Midori; Mine, Mariko; Yokota, Kenichi

    2013-10-01

    Atomic bomb survivors have been reported to have an increased risk of some cancers, especially leukemia. However, the risk of prostate cancer in atomic bomb survivors is not known to have been examined previously. This study examined the association between atomic bomb radiation and the incidence of prostate cancer among male Nagasaki atomic bomb survivors. The subjects were classified by distance from the hypocenter into a proximal group (atomic bomb survivors who were alive in 1996. The Cox proportional hazard model was used to estimate the risk of prostate cancer development, with adjustment for age at atomic bomb explosion, attained age, smoking status, and alcohol consumption. Compared with the distal group, the proximal group had significant increased risks of total, localized, and high-grade prostate cancer (relative risk and 95% confidence interval: 1.51 [1.21-1.89]; 1.80 [1.26-2.57]; and 1.88 [1.20-2.94], respectively). This report is the first known to reveal a significant relationship between atomic bomb radiation and prostate cancer. PMID:23859763

  11. Psychological problems of atomic bomb survivors from the medical social worker's standpoint

    Mental data from 80 A-bomb survivors were available during a 20-year period 1973-1992. Types of A-bomb survivors were classified into (1) directly exposed A-bomb survivors, (2) A-bomb survivors living in the United States, (3) those living in prefectures other than Nagasaki, (4) ex-soldiers, (5) A-bomb survivors having family problems and others, (6) the demented elderly, (7) the alcoholic, and (8) others. Mental problems were judged as psychogenic, endogenous, and exogenous. Mental problems were most frequently associated with Type 1 (34.9%), followed by Type 8 (21.0%), Type 2 (18.6%), and Type 3 (7.0%). Noticeable finding was that Type 1 A-bomb survivors suffered from psychogenic and exogenous mental problems in an extremely high incidence, as compared with the non-exposed group (66.3% vs 24%). The incidence of both exogenous and endogenous problems was higher in the non-exposed group (32.6% and 24.5%) than the exposed group (23.2% and 10.5%). There was no significant gender difference in the development of mental problems. According to types of A-bomb survivors, both psychogenic and exogenous mental problems were most common for Type 1. The incidence of psychogenic problems was 2.85 times higher than that of exogenous problems. (N.K.)

  12. The current mortality rates of A-bomb survivors in Nagasaki-city

    The purpose of the paper is to describe and investigate the death rate of about 110,000 A-Bomb survivors who have been registered in Nagasaki-city since 1957. There were 7,780 deaths among the A-Bomb survivors during 1970 -- 76 from which the age-specific death rates are calculated and compared with those of non-exposed controls in Nagasaki-city. The results are as follows: (1) The age-specific death rates by all causes of A-Bomb survivors are lower than those of the controls. (2) The age-specific death rates by the cerebrovascular disease (ICD 430 - 438) are also lower in A-Bomb survivors than in others. (3) The age-specific death rates by all malignant neoplasms are nearly the same between A-Bomb survivors and the controls. It is strongly suggested from these results that, although there may still exist a number of A-Bomb survivors having been suffered from the late effects of radiation, financial or medical aid supplied by the ministry and other organizations have done good work in advancing the health care of A-Bomb survivors.

  13. Explosion and final state of the charged black hole bomb

    Sanchis-Gual, Nicolas; Montero, Pedro J; Font, José A; Herdeiro, Carlos

    2015-01-01

    A Reissner-Nordstr\\"om black hole (BH) is superradiantly unstable against spherical perturbations of a charged scalar field, enclosed in a cavity, with frequency lower than a critical value. We use numerical relativity techniques to follow the development of this unstable system -- dubbed charged BH bomb -- into the non-linear regime, solving the full Einstein--Maxwell--Klein-Gordon equations, in spherical symmetry. We show that: $i)$ the process stops before all the charge is extracted from the BH; $ii)$ the system settles down into a hairy BH: a charged horizon in equilibrium with a scalar field condensate, whose phase is oscillating at the (final) critical frequency. For low scalar field charge, $q$, the final state is approached smoothly and monotonically. For large $q$, however, the energy extraction overshoots and an explosive phenomenon, akin to a $bosenova$, pushes some energy back into the BH. The charge extraction, by contrast, does not reverse.

  14. Relationship between cataracts and epilation in atomic bomb survivors

    Among 1713 atomic bomb survivors who underwent ophthalmological examinations from 1963-1964, the risk of cataract formation per unit dose of radiation was significantly greater for those who reported hair loss of 67% or more after exposure (the epilation group) than for those who reported less or no hair loss (the no-epilation group) (P,0.01). Such an epilation effect has also been associated with leukemia mortality and the frequency of chromosome aberrations. Although this might be interpreted as indicating differential sensitivity to radiation between the epilation group and the no-epilation group, it could also be explained by imprecision in dose estimates. We have calculated that a 48% random error in DS86 dose estimates could be in accordance with the dose-response relationship for the prevalence of cataracts in the epilation group or the no-epilation group. Possible mechanisms for variations in radiosensitivity are discussed. 37 refs., 2 figs., 4 tabs

  15. Children of the atomic bomb survivors: A genetic study

    This volume represents the results of over 40 years of study of the latent health effects on the survivors of the atomic bomb blasts. Planning for this research began in 1946 and data collection has been ongoing since 1948. The work represents the efforts of both US and Japanese agencies and presents 13 papers which the editors believe represent the best scientific information related to the genetic effects of radiation exposure. In general, the results presented here indicate that radiation exposure effects on reproductive cells are less than previously thought. The paper contained here examine that question in light of effects on pregnancy outcome, sex ratio, congenital defects, and early mortality of children. The papers also present helpful comparison of these results with the results seen in experimental radiation studies with animals. For anyone interested in the risks associated with radiation studies, this book represents a vital collection of information

  16. A-bomb survivors: reassessment of the radiation hazard.

    Stewart, A M; Kneale, G W

    1999-01-01

    Newly released data from the Radiation Effects Research Foundation on the survivors of the Hiroshima and Nagasaki A-bombing allow a reassessment of radiation hazards. It appears that deaths from marrow damage (such as aplastic anaemia) continued after 1950. The Life Span Study cohort appears biased in favour of persons with high immunological competence, the result of infants and the elderly being more likely to die before 1950 than young adults. A study of survivors of in utero exposures suggests that embryos are more sensitive to the lethal effects of radiation than more mature foetuses. Current estimates of cancer risks from radiation may only apply to young adults with high immunological competence; young children and the elderly may be at greater risk. PMID:10218002

  17. The Radium Terrors. Science Fiction and Radioactivity before the Bomb.

    Candela, Andrea

    2015-01-01

    At the beginning of the 20th century the collective imagination was fascinated and terrified by the discovery of radium. A scientific imagery sprang up around radioactivity and was disseminated by public lectures and newspaper articles discussing the ambiguous power of this strange substance. It was claimed that radium could be used to treat cholera, typhus and tuberculosis, but at the same time there were warnings that it could be used for military purposes. The media and the scientists themselves employed a rich vocabulary influenced by religion, alchemy and magic. The ambivalent power of radioactive elements exerted a great influence on science fiction novelists. This paper will examine some significant works published in Europe, America and Russia during the first decades of the 20th century and their role in the creation of the complex imagery of radioactivity that seized the public imagination long before the invention of the atomic bomb.

  18. Lessons from the atomic bomb about secondary MDS.

    Hata, Tomoko; Imanishi, Daisuke; Miyazaki, Yasushi

    2014-12-01

    Myelodysplastic syndromes (MDSs) is a hematological neoplasm defined by ineffective hematopoiesis, dysplasia of hematopoietic cells, and risk of progression to acute leukemia. MDS occurs as de novo or secondary, and chemoradiotherapy for cancers is thought to increase the risk of MDS among patients. Recently, an epidemiological study for MDS among A-bomb survivors was performed, and it clearly demonstrated that the exposure to external radiation significantly increased the risk of MDS. Precise epidemiological data among survivors have revealed important clinical factors related to the risk of leukemias. In this review, by comparing data for secondary MDS and leukemia/MDS among survivors, several factors which would affect the risk of MDS, especially secondary MDS, are discussed. PMID:25240475

  19. Peace without the bomb? - To organize nuclear disarmament

    With a Christian ethical approach, the authors discuss the relevance of the nuclear bomb for great powers in front of risks of terrorism, or in front of instabilities around the Mediterranean Sea and in Africa. As some countries like Pakistan, India, China or Israel consider this weapon as a guarantee for their security, and as other countries like Iran and North Korea are examples of nuclear proliferation, it seems that the nuclear weapon does not respond to present security issues. The authors state and explain that unilateral disarmament could be a way to collective security. This approach is based on the Pacem in Terris encyclical. The authors have met representatives of peace movements and senior army officials

  20. Clinical studies of lung cancer of atomic bomb survivors, 4

    A comparative study was made on complications of lung cancer in 188 A-bomb survivors (group 1) and 327 non-exposed patients (group 2) treated from 1972 through 1982. The incidence of complications was higher in group 1 (32 %) than in group 2 (20 %). Complications occurred most frequently in the respiratory system, followed by those in the circulatory system and diabetes mellitus in both groups. Patients with complications in the respiratory, circulatory, or nervous system tended to be inoperable. For patients with clinical stage I or II developing complications, the prognosis was worse as compared with those without complications. Long-term survival can be achieved in two patients with early stage lung cancer in whom surgical treatment was impossible because of the association of severe complications. (Namekawa, K.)

    Radiation-induced chromosome rearrangements are known to have persisted in the peripheral blood lymphocytes of atomic bomb survivors in Hiroshima and Nagasaki. A dose-response relationship for chromosome aberration frequencies has been observed in both cities. A preliminary analysis of cytogenetic data indicates that the inter-city difference observed with the T65D dose estimate becomes less pronounced with the new DS86 dosimetry system. The regression coefficient of the dose-response curves is nevertheless higher in Hiroshima than in Nagasaki. The majority of chromosome aberrations detectable to date are of the stable type, such as translocations and inversions, and they have formed the dose-response relationship. (author)

  2. Activation of cobalt by neutrons from the Hiroshima bomb

    A study has been completed of cobalt activation in samples from two new locations in Hiroshima. The samples consisted of a piece of steel from a bridge located at a distance of about 1300 m from the hypocenter and pieces of both steel and concrete from a building located at approximately 700 m. The concrete was analyzed to obtain information needed to calculate the cobalt activation in the two steel samples. Close agreement was found between calculated and measured values for cobalt activation of the steel sample from the building at 700 m. It was found, however, that the measured values for the bridge sample at 1300 m were approximately twice the calculated values. Thus, the new results confirm the existence of a systematic error in the transport calculations for neutrons from the Hiroshima bomb. 52 refs., 32 figs., 16 tabs

  4. Organ dose estimates for the Japanese atomic-bomb survivors

    Recent studies concerning radiation risks to man by the Committee on Biological Effects of Ionizing Radiation of the National Academy of Sciences-National Research Council and the United Nations Scientific Committee on the Effects of Atomic Radiation have emphasized the need for estimates of dose to organs of the Japanese atomic-bomb survivors. Shielding of internal organs by the body has been investigated for fission-weapon gamma rays and neutrons, and ratios of mean absorbed dose in a number of organs to survivors' T65D assignments of tissue kerma in air are provided for adults. Ratios of mean absorbed dose to tissue kerma in air are provided also for the thyroid and active bone marrow of juveniles. These organ dose estimates for juveniles are of interest in studies of radiation risks due to an elevated incidence of leukemia and thyroid cancer in survivors exposed as children compared to survivors exposed as adults

  5. Oscillatory thermal instability - the Bhopal disaster and liquid bombs

    Ball, Rowena

    2011-01-01

    Thermal runaway reactions were involved in the Bhopal disaster of 1984, in which methyl isocyanate was vented from a storage tank of the liquid, and occur in liquid peroxide explosions, yet to date there have been few investigations into the mechanism of thermal runaway in such liquid thermoreactive systems. Consequently protocols for storing thermally unstable liquids and deactivating liquid bombs may be suboptimal. In this work the hydrolysis of methyl isocyanate and the thermal decomposition of triacetone triperoxide were simulated using a gradientless, continuous-flow reactor paradigm. This approximation enabled stability analyses on the steady state solutions of the dynamical mass and enthalpy equations. The results indicate that thermal runaway in both systems is due to the onset of a large amplitude, hard thermal oscillation initiated at a subcritical Hopf bifurcation. This type of thermal misbehaviour cannot be predicted using classical ignition theory, and may be typical of liquid thermoreactive syst...

  6. Atomic bombing and nuclear energy development in Japan

    The victims of Hiroshima and Nagasaki introduced Japan to nuclear power. Approximately ten years after the bombing, the Japanese Parliament adopted a ''Nuclear Basic Law'', and unanimously proclaimed independence, democracy, and openness as indispensable prerequisites for the continued peaceful utilization of nuclear power. For more than a decade, the political party in government and the opposition parties unanimously adopted all legislation and ordinances connected with nuclear power as well as the necessary budgets. This led to the establishment of research and development institutions. The basic consensus underlying nuclear development in Japan has been the exclusion of any military use. The Japanese public perceives that a military component is not feasible in the country's development of nuclear power. (orig./UA)

  8. Whole-blood phagocytic and bactericidal activities of atomic bomb survivors, Hiroshima and Nagasaki

    This in vitro study evaluated the phagocytic and bactericidal activities of leukocytes in aliquots of whole blood from Hiroshima and Nagasaki atomic bomb survivors for Staphylococcus aureus. The data were analyzed by multiple linear regression. Any significant effects of exposure to A-bomb radiation could not be detected for both phagocytic and bactericidal activities of whole blood from A-bomb survivors. In addition, there were no significant effects of age categories, sex or city, except in neutrophil counts. (J.P.N.)

  9. Sulfur activation at the Little Boy-Comet Critical Assembly: A replica of the Hiroshima bomb

    Kerr, G. D.; Emergy, J. F.; Pace, J. V., III

    1985-04-01

    Studies have been completed on the activation of sulfur by fast neutrons from the Little Boy-Comet Critical Assembly which replicates the general features of the Hiroshima bomb. The complex effects of the bomb's design and construction of leakage of sulfur-activation neutrons were investigated both experimentally and theoretically. Our sulfur activation studies were performed as part of a larger program to provide benchmark data for testing of methods used in recent source-term calculations for the Hiroshima bomb. Source neutrons capable of activating sulfur play an important role in determining neutron doses in Hiroshima at a kilometer or more from the point of explosion.

  10. Noncancer mortality among the Japanese atomic bomb survivor

    Yukiko Shimizu and her colleagues from the Radiation Effects Research Foundation in Hiroshima have recently published the results of the updated analysis of deaths from causes other than cancer among the Japanese survivors of the atomic bomb explosions, covering the period 1950-1990 (Shimizu Y, Pierce D A, Preston D L and Mabuchi K 1999 Studies of the mortality of atomic bomb survivors. Report 12, Part II. Noncancer mortality: 1950-1990 Radiat. Res. 152 374-389). The primary analyses are based on 27 000 deaths, 30% more than in the previous report on this subject. These latest findings confirm a statistically significant trend of an increasing rate of noncancer mortality with increasing dose, due to trends for diseases of circulatory, digestive and respiratory systems. At 1 Sv, the proportional increase is about 10%, much smaller than for cancer (at around 50%), but the numbers of excess deaths are more comparable. The all-important question of the dose-response relationship remains unresolved: linearity is possible, but the data are also consistent with a threshold at 0.5 Sv. The authors conclude that misclassification, confounding or selection effects are unlikely to fully explain the findings. Enhanced knowledge of the biological mechanisms underlying these epidemiological observations would enable the nature of the dose-response to be better understood. Also reported is a statistically significant trend of an increasing rate of noncancer blood diseases with dose, which cannot be accounted for by misclassification. This paper also confirms that suicide rates tend to decrease with increasing dose. Clearly, the impact of these latest results for noncancer mortality upon risk estimates for low dose exposures is going to be much discussed by the radiological protection community. (author)

  11. Thyroid cancer incidence among atomic bomb survivors, 1958-79

    One hundred and twelve cases of thyroid cancer diagnosed during the period 1958-79 among the extended Life Span Study cohort in Hiroshima and Nagasaki were studied. There was a statistically significant association between thyroid cancer incidence and exposure to atomic bomb radiation. The adjusted excess relative risk (ERR) per gray was 1.1 (95% confidence interval=0.3-2.5) and the adjusted absolute risk per 104 PYGy was 0.59 (95% confidence interval=0.2-1.7). Based on a comparison of the deviances obtained from relative and absolute risk models, a simple linear relative risk model appeared to fit the data better than an absolute risk model; however, it would not be appropriate to conclude that the data conform strictly to a relative risk pattern. The incidence of thyroid cancer among the members of the Adult Health Study (AHS) population, who have received biennial medical examinations at the Atomic Bomb Casualty Commission and its successor the Radiation Effects Research Foundation, since 1958, was 70% higher than that among the rest of the extended LSS cohort after adjustments for city, sex, log age, calendar year, and Dosimetry System 1986 dose. There was no significant difference between the slope of the dose-response curve for AHS and non-AHS participants, although the estimated ERRs at 1 Gy for the AHS and non-AHS population were 1.6 and 0.3, respectively. The elevated risk appeared to be confined to women, and there was an increasing risk with decreasing attained age and age at exposure. (J.P.N.)

  12. Geographical shielding of Nagasaki A-bomb exposure

    This study was performed to collect data concerning the title in Old Nagasaki City for the future assessment of exposure effect on cancer mortality as there had been no such data in Nagasaki University. The City areas were classified in 237 regions shielded (45), partly shielded (41) and not-shielded (151) by hills surrounding the City along with the 5 steps of distances from <1.0 to 5 km or more from the hypocenter (503 m high) + Nishiyama region (shielded) with use of Using Arc View GIS (Geological Information System, USA). Cancer mortality in each region was studied on total 43,735 survivors directly exposed to A-bomb at the age of <30 y who had lived in the City on Jan. 1, 1970. Cancer death was studied on this cohort until Dec. 31, 2011 (during 42 years). Numbers of not-shielded people were estimated to be 8,779 (49.3%) males and 13,430 (51.8%) females. Curves vs time of their mortality per 100 thousands during the 42 years were found to have the peak of about 600 males exposed at 1.0-1.9 km from the hypocenter and about 350 females at <1.0 km. The higher was the mortality, the closer was the distance from the hypocenter. The correlation between the mortality and distance was thus found, but not in shielded people. The effect of this geographical shielding should be considered in assessment of Nagasaki A-bomb exposure. (T.T.)

  13. Detecting body cavity bombs with nuclear quadrupole resonance

    Collins, Michael London

    Nuclear Quadrupole Resonance (NQR) is a technology with great potential for detecting hidden explosives. Past NQR research has studied the detection of land mines and bombs concealed within luggage and packages. This thesis focuses on an NQR application that has received less attention and little or no publicly available research: detecting body cavity bombs (BCBs). BCBs include explosives that have been ingested, inserted into orifices, or surgically implanted. BCBs present a threat to aviation and secure facilities. They are extremely difficult to detect with the technology currently employed at security checkpoints. To evaluate whether or not NQR can be used to detect BCBs, a computational model is developed to assess how the dielectric properties of biological tissue affect the radio frequency magnetic field employed in NQR (0.5-5MHz). The relative permittivity of some biological tissue is very high (over 1,000 at 1MHz), making it conceivable that there is a significant effect on the electromagnetic field. To study this effect, the low-frequency approximation known as the Darwin model is employed. First, the electromagnetic field of a coil is calculated in free space. Second, a dielectric object or set of objects is introduced, and the free-space electric field is modified to accommodate the dielectric object ensuring that the relevant boundary conditions are obeyed. Finally, the magnetic field associated with the corrected electric field is calculated. This corrected magnetic field is evaluated with an NQR simulation to estimate the impact of dielectric tissue on NQR measurements. The effect of dielectric tissue is shown to be small, thus obviating a potential barrier to BCB detection. The NQR model presented may assist those designing excitation and detection coils for NQR. Some general coil design considerations and strategies are discussed.

  14. Malignant lymphoma and multiple myeloma in atomic-bomb survivors

    Of autopsies performed from 1956 to 1976 in Hiroshima Atomic Bomb Hospital, 22 cases of reticulo-sarcoma, 4 cases of lymphosarcoma, 6 cases of Hodgkin's disease, and 9 cases of multiple myeloma were observed in atomic bomb survivors. In regard to the relationship between exposure distance and the number of autopsied cases, the nearer the exposure distance to the center of explosion, the higher the incidence of reticulo-sarcoma in male patients only. Since 1966 cases of malignant lymphoma and multiple myeloma increased with an increase in the number of autopsied cases. An increase in incidences of lymphoma and multiple myeloma was marked especially in the group which entered the city after the explosion. There were more cases of malignant lymphoma in aged patients in the exposed group than in the non-exposed group. Lymphosarcoma and Hodgkin's disease were observed more often in women in the exposed group than in men. Many cases of reticulo-sarcoma in the digestive tract, especially primary stomach reticulo-sarcoma, were observed in the group which was exposed at places over 2 km from the center of explosion and in the exposed group which entered the city after the explosion. Four cases of leukemic reticulo-sarcoma were observed. With respect to histological types of reticulosarcoma, an undifferentiated type was observed in the group exposed at places over 2 km from the center of explosion and in the exposed group which entered the city after the explosion. Incidence of multiple myeloma was high in the group exposed at places within 2 km of the center of explosion. Three cases in which myeloma cells showed a tendency toward diffuse infiltration and proliferation within the bone marrow were observed in the exposed group. (Tsunoda, M.)

  16. Clinical study of infectious diseases on aged A-bomb survivors in Hiroshima Welfare Home for aged A-bomb survivors

    Infections, especially urinary passage and respiratory infections of aged A-bomb survivers under special protective care was examined. Urinary passage infections have recently shown an increasing tendency. These infections are related to the factors such as their basic diseases and wearing napkins rather than a severe degree of protective care. In the case of respiratory infection, diseases such as influenza are observed rather in patients who can walk, but they tend to be aggravated in bedridden patients. It cannot be said that more urinary passage infections are observed in A-bomb survivers than non A-bomb survivers. Both urinary passage infection and respiratory infection tend to recur repeatedly. Aged A-bomb survivers show no significant difference of acquired immunity from that of non A-bomb survivers group. However, a maintenance of neutralizing antibody by vaccination of influenza in the former is worse than in the latter. Bedridden patients show a higher rate of infection to potential urinary passage diseases than patients who can walk, irrespective of sex. Moreover, bedridden patients have a large number of bacteria, but other significant host reaction couldn't be observed. In bedridden patients with potential urinary passage infection, a variety of bacteria, most of which are bacteria resistant to rutinely used broad spectrum antibiotics, is detected. As a main disease or a direct cause of death, pyelonephritis in women and bronchopneumonia are often observed. (Iwagami, H.)

  18. CPT site characterization for seismic hazards in the New Madrid seismic zone

    Liao, T.; Mayne, P.W.; Tuttle, M.P.; Schweig, E.S.; Van Arsdale, R.B.

    2002-01-01

    A series of cone penetration tests (CPTs) were conducted in the vicinity of the New Madrid seismic zone in central USA for quantifying seismic hazards, obtaining geotechnical soil properties, and conducting studies at liquefaction sites related to the 1811-1812 and prehistoric New Madrid earthquakes. The seismic piezocone provides four independent measurements for delineating the stratigraphy, liquefaction potential, and site amplification parameters. At the same location, two independent assessments of soil liquefaction susceptibility can be made using both the normalized tip resistance (qc1N) and shear wave velocity (Vs1). In lieu of traditional deterministic approaches, the CPT data can be processed using probability curves to assess the level and likelihood of future liquefaction occurrence. ?? 2002 Elsevier Science Ltd.

  20. JOURNALISM ETHICS AND ACCEPTANCE OF GIFTS: A view from Madrid journalists

    Susana Herrera Damas

    2011-02-01

    Full Text Available The aim of this article is to present the partial results of a larger
    research project on journalistic ethics from the point of view of the professionals themselves. Specifically, the following pages analyze the perception of Madrid journalists with respect to the legitimacy of accepting various gifts when carrying out their work. The results of 30 in-depth interviews and 410 surveys of newspaper, radio, television, online and press office journalists who carry out their professional activity in the Autonomous Community of Madrid show that this group is very reluctant to accept gifts with a monetary value of over €200, or to carry out activities financed by a news source. Fewer problems arise regarding acceptance of presents of nominal value of a promotional merchandising nature, free tickets to shows and exhibitions, or paid meals and trips.

  1. Happiness on the street: Overall happiness among homeless people in Madrid (Spain).

    Panadero, Sonia; Guillén, Ana Isabel; Vázquez, José Juan

    2015-07-01

    This article tests a hypothesized model of overall happiness among homeless people in Spain. The research was conducted based on a representative sample of homeless people in Madrid (n = 235), all adults, who had spent the night before the interview in a shelter for homeless people, on the street or in other places not initially designed for sleeping, or who were in supervised accommodation for homeless people at the time of the interview. Information was gathered using a structured interview. The results obtained show that around half of the homeless people in Madrid said that they were happy. A positive meta-stereotype and a better perceived general health were associated with a higher overall happiness, while feelings of loneliness were associated with a lower overall happiness. Happiness also showed a significant effect on future expectations. Disabilities and handicaps had a significant effect on perceived general health, which was in turn associated with overall happiness among homeless people. PMID:26167804

  4. Assessment of the Atmospheric Suspended Particles Pollution in the Madrid Air Quality Networks

    Suspended particles are a very complex type of atmospheric pollution because of their chemical composition and size. In fact, there are a quite high number of particles sources which are linked to different physicochemical processes that determine their size. At present particles smaller than 10 μm are considered the most dangerous, as has been recently pointed out by numerous epidemiologic studies. In this way, more restrictive concentration limit values have been approved in the EU countries, so an assessment of present airborne concentration values and the sources apportionment in their most representative areas is needed. In the Madrid Community a first approaching of these and other aims, has been carried out from an analysis of the Madrid Air Quality networks data. This will contribute to the establishment of concentration levels abatement strategies. (Author) 111 refs

  1. Effects of bombing after five years: Development of early maladaptive cognitive schemas in children

    Nikoloski-Končar Nataša

    2006-01-01

    Full Text Available The main aim of the study is to examine effects of bombing on development of early maladaptive schemas in children who live in directly bombed towns in comparison with children who live in towns not directly exposed to bombing. The subjects were twelve years old at the moment of testing (February 2005 meaning that they were at the age of seven during the bombing. Additional aim was to examine gender differences in development of early maladaptive schemas. The theory of Young (1990 provided framework for the study. According to the theory, early maladaptive cognitive schemas, which present basis for psychological disorder later in life, begin to develop in childhood in connection with traumatic experiences and/or other aversive circumstances. The results showed that the early maladaptive schemas are more frequent in children from directly exposed towns; and in male subjects comparing with females.

    Full Text Available This paper presents a series of experimental studies to determine the basic characteristics and features of the transformation of small water droplets (3–6 mm and large water bombs (50–100 mm in free fall. Investigations have been carried out using cameras “Phantom V411” and “Phantom Miro M310”. Software “Tema Automotive” have been used for data processing from video recordings. The regulations of the surface transformations of small droplets and large water bombs have been established. The stages of transformation (disintegration have been established for large water bombs. The mechanisms of deformation have been defined for small droplets. The characteristic times have been determined for the defined stages of transformation. The study demonstrates the influence of the initial size of droplets and water bombs on the times and velocities of considered processes.

  3. Radiation exposure and disease questionnaires of early entrants after the Hiroshima bombing

    It is popularly known that people who entered into the ground-zero area shortly after the atomic bombings in Hiroshima and Nagasaki suffered from various syndromes similar to acute radiation effects. External exposures from neutron-induced radionuclides in soil have recently been reassessed based on DS02 calculations as functions of both distance from the hypo-centres and elapsed time after the explosions. Significant exposure due to induced radiation can be determined for those who entered the area within 1000 m from the hypo-centres shortly after the bombing. Although it was impossible to track the action of each of the survivors over the days or weeks following the bombings in order to make reliable dose estimates for their exposures to soil activation or fallout, four individuals among those early entrants were investigated here to describe useful information of what happened shortly after the bombing.

  4. Investigation for effects of the atomic bomb on Nagasaki. γ-ray measurements by Neher electrometer

    Neher electrometer, invented as an equipment to investigate the relationship of cosmic ray and terrestrial magnetism in 1930s, had excellent properties as an equipment to measure γ-ray outdoor and thus was used for measurement of radiation exposure after A-bomb explosion in Hiroshima and Nagasaki. In Nagasaki, measurement with this equipment enabled to locate the bombing center where the monument is standing now in the A-bomb Park. Measurement also revealed that the circular earth surface of 2000 m diameter had the induced radioactivity by neutron and that outside the area, the γ-ray intensity was virtually similar to the background level. Ash composing of Pu and other fission products moved over Konpira-san on the west wind, most of which came down with rainfall onto around Nishiyama reservoir. In the A-bomb movies, there is a scene that Neher electrometer was working for γ-ray measurement. (K.H.)

    Vissers, Gregal J M; Rutten, Robert J; Carlsson, Mats; De Pontieu, Bart

    2015-01-01

    Ellerman bombs are transient brightenings of the extended wings of the solar Balmer lines in emerging active regions. We describe their properties in the ultraviolet lines sampled by the Interface Region Imaging Spectrograph (IRIS), using simultaneous imaging spectroscopy in H$\\alpha$ with the Swedish 1-m Solar Telescope (SST) and ultraviolet images from the Solar Dynamics Observatory for Ellerman bomb detection and identification. We select multiple co-observed Ellerman bombs for detailed analysis. The IRIS spectra strengthen the view that Ellerman bombs mark reconnection between bipolar kilogauss fluxtubes with the reconnection and the resulting bi-directional jet located within the solar photosphere and shielded by overlying chromospheric fibrils in the cores of strong lines. The spectra suggest that the reconnecting photospheric gas underneath is heated sufficiently to momentarily reach stages of ionization normally assigned to the transition region and the corona. We also analyze similar outburst phenome...

  10. Threat perception after the Boston Marathon bombings: The effects of personal relevance and conceptual framing.

    Wormwood, Jolie Baumann; Lynn, Spencer K; Feldman Barrett, Lisa; Quigley, Karen S

    2016-01-01

    We examined how the Boston Marathon bombings affected threat perception in the Boston community. In a threat perception task, participants attempted to "shoot" armed targets and avoid shooting unarmed targets. Participants viewing images of the bombings accompanied by affectively negative music and text (e.g., "Terror Strikes Boston") made more false alarms (i.e., more errors "shooting" unarmed targets) compared to participants viewing the same images accompanied by affectively positive music and text (e.g., "Boston Strong") and participants who did not view bombing images. This difference appears to be driven by decreased sensitivity (i.e., decreased ability to distinguish guns from non-guns) as opposed to a more liberal bias (i.e., favouring the "shoot" response). Additionally, the more strongly affected the participant was by the bombings, the more their sensitivity was reduced in the negatively framed condition, suggesting that this framing was particularly detrimental to the most vulnerable individuals in the affected community.

  11. Research on dose by instant nuclear radiation from neutron bomb explosion

    Objective: To research the spatial distribution of personal absorbed dose (Dp(10)) about instant neutrons and γ-radiations at different ranges in the explosive field of neutron bomb. Methods: based on the analysis to the construction and the explosive principle of neutron bombs, a model for calculation was built, and Monte Carlo method was used. Results: Some features about personal absorbed dose (Dp(10)) of instant neutrons and γ-radiations at different ranges in space were observed. Conclusion: The authors hold that the strong γ-radiations would accompany the high-energy neutron radiation in the explosive field of neutron bombs. Meanwhile, the authors evaluated the killing effect of the instant radiation from a 1 kt neutron bomb

  12. Pattern of injury in those dying from traumatic amputation caused by bomb blast.

    Hull, J B; Bowyer, G W; Cooper, G J; Crane, J

    1994-08-01

    Traumatic amputation of limbs caused by bomb blast carries a high risk of mortality. This paper describes 73 amputations in 34 deaths from bomb blast in Northern Ireland. The principal aim was to determine the sites of traumatic amputation to provide a biophysical basis for the development of protective measures. Few amputations were through joints; nearly all were through the bone shafts. The most common site in the tibia was the upper third. The distribution of femoral sites resulting from car bombs differed from that characterizing other types of explosion. For car bombs the principal site of amputation was the upper third; for other types of device it was the lower third. It is concluded that flailing is not a notable contributor to limb avulsion. The pattern of amputation is consistent with direct local pressure loads leading to bone fracture; the amputation itself is a secondary event arising from the flow of combustion products.

  13. Using neutron source distinguish mustard gas bomb from the others with Monte Carlo simulation method

    After Japan was defeated, the chemical weapon that left in China injured people constantly. It made very grave lost to the Chinese because of people's innocent to it. In these accidents, mustard gas bomb is the most. It is more difficult to distinguish mustard gas bomb from other normal bomb in out because it embedded in the earth for long time; leakage, eroding and rust appearance looked very serious. So the untouched measure method, neutron source inducing γ spectrum, showed very important. The Monte Carlo method was used in this paper to compute the γ spectrum when using neutron source irradiate mustard gas bomb. The characteristic radial of Cl, S, Fe and the other elements can picked up clearly. The result play some referenced role in analyzing γ spectrum. (authors)

  14. An assessment of environmental damage caused by NATO bombing of NIS Jugopetrol facilities

    This paper present our investigation of the effects of NATO bombing of the Jugopetrol facilities in Serbia during the Spring of 1999. Concentrations of hazardous material in air, water and soil have been measured and compared to the situation before the bombing. Only partial results are presented in this paper. High concentrations of hydrocarbons were detected in the air immediately after the bombing and the destruction of installations, due to burning and evaporation of oil derivatives. A great amount of spilled mineral oils has been detected in water and soil near the destroyed installations. We have detected a noticeable increase in pollution after the NATO bombing. In addition to above mentioned pollution, the destruction of large parts of waste treatment system within the Jugopetrol's installations caused severe environmental problems. The recovery of the destroyed installation and waste treatment systems require considerable amount of money and time, and cannot be accomplished without the help of foreign investment. (author)

  15. Soil characterization and vulnerability indices of the Autonomous region of Madrid. Scale 1:200.000

    Radioactive contamination of the soil due to a nuclear accident is a risk for the population. A research project, within the program of Radiological Protection by Intervention in CIEMAT, has been developed to study the behaviour of radionuclides in soils. An evaluation of the radiological vulnerability considering the external irradiation and the food chain pathway for caesium and strontium has been determined using partial and global indices, which indicate the potential transfer of the radionuclides via the two mentioned pathways. A detailed study of the soils found in the Autonomous Region of Madrid was carried out with data from individual soil profiles and combining data obtained from maps with a Geographic Information System in order to obtain a spatial distribution of the results. The soil vulnerability for the external irradiation pathway of caesium and strontium is in general found to be higher in more developed soils located in the south and leading to the foothills of the Sierra of Madrid in the north. The vulnerability for the food chain pathway is found to be higher in the less developed soils in acid conditions situated in the Sierra of Madrid. (Author) 11 refs

  2. A crack model of the Hiroshima atomic bomb. Explanation of the contradiction of 'Dosimetry system 1986'

    There has been a discrepancy between the Dosimetry system 1986 (DS86) and measured data, and its causes have long been discussed. In this study the problem is discussed according to a bare-fission-neutron leakage model of the Hiroshima atomic bomb. The Hiroshima type bomb was a gun type and two parts of subcritical uranium was brought together in the head of the bomb, which was made with a thick steel body. One of the difficulties is that all of the atomic bombs ever used have been an implosion type except for this Hiroshima type. Therefore, there are no available data for this type of the atomic bomb. The present model assumes a disassembly of the bomb (crack formation) at the process of the chain reaction. The crack has a 3 cm parallel spacing, which is parallel to the horizontal plane across the fission center in the bomb body. In addition, the height of the neutron emission point was elevated about 90 m from the estimated height of 580 m. The height of 580 m was estimated by the shadows produced according to heat ray on the corner of concrete buildings and tombstones. Therefore it implies the bomb dropped 90 m and formed fireball. In the present study the neutron transport calculations were performed, and it was verified that the activity data of 152Eu, 60Co and 36Cl which was induced by thermal neutrons, and 32P by fast neutrons, are simultaneously explained within the data scattering. The kerma at the typical 1.5 km ground range distances increases 3 and 8 times higher than DS86 based on the symmetric and asymmetric model, respectively. Influence for the radiation risk estimation based on the epidemiological data in Hiroshima and Nagasaki should be reconsidered. (author)

    Finally the German atomic physicists around Heisenberg, von Weizsaecker, and Hahn worked on their ''uranium machine'' in a Swabian beer-cellar - and took themselves for the world elite of nuclear research. In imprisonment they heared from the dropping of the Hiroshima bomb - a shock. Richard von Schirach shows the hindered ''fathers of the German atomic bomb'' in close-up, their eagerness, their hybris, their true importance, and their attempts to give after the war a new interpretation of their own role. A book, which raises in the sense of Duerrenmatt the question for the responsibility of science.

  9. Myelodysplastic syndromes in atomic bomb survivors in Nagasaki. A preliminary analysis

    Myelodysplastic syndromes (MDS) are a heterogenous hematological group characterized by an ineffective hematopoiesis resulting in a variety of cytopenias, morphological abnormalities of blood cells, chromosomal aberrations, and an increases risk of transformation into acute myeloid leukemia. Despite of its nature of close relation to leukemia, MDS has been not well investigated in atomic bomb (A-bomb) survivors. We conducted a retrospective cohort study with over 80,000 A-bomb survivors in Nagasaki to assess the incidence of MDS and its relation with A-bomb exposure status. In a preliminary analysis, we confirmed 162 MDS cases during 1980 to 2004. The median age at diagnosis was 71 years old. The incidence rate was higher in men than women, and an inverse relationship was observed between incidence of MDS and the distance from the hypocenter. We suggest that A-bomb radiation may affect the occurrence of MDS in A-bomb survivors even more than 50 years passed after the explosion. Further detail analyses are necessary to confirm these results. (author)

  10. Studies on the effects on progeny of A-bomb survivors

    With the aim of identifying the delayed effects of A-bomb radiation, the Twin Control Study was undertaken using different population samples. In medical and physical examinations comprising 49 A-bomb exposed twins, no relation was seen between distance from the hypocenter and the development of specific diseases, such as HLA-related disease, or Ig values. Epidemiological analyses of the data from 536 twin pairs born to A-bomb survivors showed no relation between disase incidence and distance from the hypocenter. Questionnaire data, which were analyzed from 347 respondents (66 %) of 523 A-bomb survivors and from 553 respondents (62 %) of 888 twins or their siblings in the F1 generation, provided no consistent tendency for health condition. In analysing data from 41 A-bomb exposed twin pairs and from 13 twin pairs and their 26 siblings in the F1 generation, there was no consistent trend for the natural history of diseases. Examinations on immune status in 25 subjects, including A-bomb survivors and their children, revealed abnormal T4/T8 ratios in survivors exposed at ≤ 2,000 m from the hypocenter, suggesting the possibility of occult immunodeficiency.

  11. ELLERMAN BOMBS AT HIGH RESOLUTION. II. TRIGGERING, VISIBILITY, AND EFFECT ON UPPER ATMOSPHERE

    We use high-resolution imaging spectroscopy with the Swedish 1-m Solar Telescope (SST) to study the transient brightenings of the wings of the Balmer Hα line in emerging active regions that are called Ellerman bombs. Simultaneous sampling of Ca II 8542 Å with the SST confirms that most Ellerman bombs also occur in the wings of this line, but with markedly different morphology. Simultaneous images from the Solar Dynamics Observatory (SDO) show that Ellerman bombs are also detectable in the photospheric 1700 Å continuum, again with differing morphology. They are also observable in 1600 Å SDO images, but with much contamination from C IV emission in transition-region features. Simultaneous SST spectropolarimetry in Fe I 6301 Å shows that Ellerman bombs occur at sites of strong-field magnetic flux cancellation between small bipolar strong-field patches that rapidly move together over the solar surface. Simultaneous SDO images in He II 304 Å, Fe IX 171 Å, and Fe XIV 211 Å show no clear effect of the Ellerman bombs on the overlying transition region and corona. These results strengthen our earlier suggestion, based on Hα morphology alone, that the Ellerman bomb phenomenon is a purely photospheric reconnection phenomenon

  12. Effect Analysis on the Radiation Dose Rate of Nagasaki Atomic Bomb Survivors by Atmospheric Condition

    The Dosimetry System 2002 (DS02) had been established to evaluate the radiation doses for the atomic bomb survivors in Hiroshima and Nagasaki. The radiation effects of neutrons and gamma-rays emitted from the atomic bombs detonated at both cities were analyzed, and two types of radiation transport codes (i.e., MCNP4C and DORT) were employed in their studies. It was specifically investigated for contribution of each type of radiations to total dose. However, it is insufficient to examine the effects by various environmental factors such as weather conditions, because their calculations were only performed under certain condition at the times of the bombings. In addition, the scope of them does not include acute radiation injury of the atomic bomb survivors in spite of important information for investigating hazard of unexpected radiation accident. Therefore, this study analyzed the contribution of primary and secondary effects (i.e., skyshine and groundshine) of neutrons emitted from the Nagasaki atomic bomb. These analyses were performed through a series of radiation transport calculations by using MCNPX 2.6.0 code with variations of atmospheric density. The acute radiation injury by prompt neutrons was also evaluated as a function of distance from the hypocenter, where hypocenter is the point on the ground directly beneath the epicenter which is the burst point of the bomb in air

    We use high-resolution imaging spectroscopy with the Swedish 1-m Solar Telescope (SST) to study the transient brightenings of the wings of the Balmer H{alpha} line in emerging active regions that are called Ellerman bombs. Simultaneous sampling of Ca II 8542 A with the SST confirms that most Ellerman bombs also occur in the wings of this line, but with markedly different morphology. Simultaneous images from the Solar Dynamics Observatory (SDO) show that Ellerman bombs are also detectable in the photospheric 1700 A continuum, again with differing morphology. They are also observable in 1600 A SDO images, but with much contamination from C IV emission in transition-region features. Simultaneous SST spectropolarimetry in Fe I 6301 A shows that Ellerman bombs occur at sites of strong-field magnetic flux cancellation between small bipolar strong-field patches that rapidly move together over the solar surface. Simultaneous SDO images in He II 304 A, Fe IX 171 A, and Fe XIV 211 A show no clear effect of the Ellerman bombs on the overlying transition region and corona. These results strengthen our earlier suggestion, based on H{alpha} morphology alone, that the Ellerman bomb phenomenon is a purely photospheric reconnection phenomenon.

    2012-01-01

    Full Text Available Background. Few disaster studies have specifically examined personality and resilience in association with disaster exposure, posttraumatic stress disorder (PTSD, and major depression. Methods. 151 directly-exposed survivors of the Oklahoma City bombing randomly selected from a bombing survivor registry completed PTSD, major depression, and personality assessments using the Diagnostic Interview Schedule for DSM-IV and the Temperament and Character Inventory, respectively. Results. The most prevalent postdisaster psychiatric disorder was bombing-related PTSD (32%; major depression was second in prevalence (21%. Bombing-related PTSD was associated with the combination of low self-directedness and low cooperativeness and also with high self-transcendence and high harm avoidance in most configurations. Postdisaster major depression was significantly more prevalent among those with (56% than without (5% bombing-related PTSD (P<.001 and those with (72% than without (14% predisaster major depression (P<.001. Incident major depression was not associated with the combination of low self-directedness and low cooperativeness. Conclusions. Personality features can distinguish resilience to a specific life-threatening stressor from general indicators of well-being. Unlike bombing-related PTSD, major depression was not a robust marker of low resilience. Development and validation of measures of resilience should utilize well-defined diagnoses whenever possible, rather than relying on nonspecific measures of psychological distress.

  15. Was Nazi Germany on the Road to an Atomic Bomb after all?

    Lustig, Harry

    2006-04-01

    The story of Germany's efforts to develop a nuclear weapon during World War II is a much written about and contentious subject. However there has been agreement on one thing: by the end of the War the Germans had not achieved and were nowhere near to building a bomb. The dispute therefore has been about why Germany did not succeed. Now, from Germany, comes a challenge to this truth, in the provocative book Hitlers Bombe by Rainer Karlsch. The bombshell in Hitler's Bombe is the assertion that German scientists developed and tested a primitive fission and fusion nuclear weapon in March 1945. Karlsch bases this claim on testimony of witnesses in 1962, previously secret Russian documents, and the results of soil tests carried out in 2004 and 2005. However the physics is very murky and it seems out of the question that Germany had enough Uranium 235 or produced any Plutonium for a bomb. Hitlers Bombe also makes other, better documented and more credible revisionist assertions. These include the claim that the Nazis did continue to try to build a bomb after 1942 and that not Werner Heisenberg, but Kurt Diebner and Walther Gerlach were then the leaders of the German Uranium project. Karlsch's book therefore deserves more attention from physicists and historians than it has received in the United States.

    Two new titanates of strontium, lithium and a 3d metal, with the composition SrLiMTi{sub 4}O{sub 11} (M=Cr,Fe), have been discovered. Single crystals were obtained by spontaneous crystallization from a high-temperature solution with LiBO{sub 2} as the solvent. The structure of SrLiCrTi{sub 4}O{sub 11} was refined in the orthorhombic space group Pnma (Z=4), while SrLiFeTi{sub 4}O{sub 11} appeared to adopt a four-times larger orthorhombic unit cell with Pbcn (Z=16). The structures can be described by a close-packed arrangement of Sr and O atoms. The unit cell contains six 'compact planes' perpendicular to [100] in the layer sequence ABACBC [(chc){sub 2}]. Ti and Cr or Fe atoms occupy some of the interstitial octahedral sites created, whereas Li atoms are in tetrahedral sites. Depending on the synthesis conditions of SrLiCrTi{sub 4}O{sub 11}, the distribution of Cr and Ti atoms on the four possible crystallographic sites is not the same. Having a similar compact-planes sequence, SrLiCrTi{sub 4}O{sub 11} and SrLiFeTi{sub 4}O{sub 11} structures differ in the arrangement of Sr and O atoms per layer of close packing, which also induces a correlated variation in the Li-tetrahedra distribution.

  18. Subclinical hyperthyroidism (Sh) in atomic-bomb survivors in Japan

    Full text: Purpose/Background Subclinical hyperthyroidism (Sh) is defined as a biochemical abnormality characterized by a subnormal level of TSH with otherwise normal thyroid tests (F T3, F T4) and no clinical symptoms. There are only a small number of cross-sectional studies on the prevalence of Sh. With the improvement of the sensitivity of TSH assay, it has become possible to survey the clinical significance of Sh. With regard to both Sh and subclinical hypothyroidism, discussions are being focused on such as the necessity of treatment. In order to elucidate the clinical significance of Sh, examination data of A-bomb survivors in Hiroshima and Nagasaki were analyzed. Subjects and Method Between 2000 and 2003, of 4,090 A-bomb survivors (1,352 males and 2,738 females with average age of 70.7), 75 individuals (1.83%) with Sh were found who had normal Free T4 (0.71∼1.51 ng/dL) and TSH<0.45 m U/L. Analysis was limited to those who had not taken antithyroid drugs or thyroxin, and the Sh group (n=35; 9 males and 26 females) was compared with a control group with TSH:0.45∼4.5 m U/L (Group C; N=3,243; 1,109 males and 2,134 females). Result: Nine individuals had TSH<0.1 m U/L. In the Sh group, six individuals were TPO antibody-positive (17%) and 14 were TG antibody-positive (40%); hence, TG antibody-positive was significantly greater in number (p=0.0096). Hematological biochemical tests showed no significant difference between the two groups. Electrocardiograms indicated that more individuals had atrial fibrillation [p=0.028; Odds ratio (OR)=3.98; 95% Confidential interval (CI)=1.2-13.7] or ventricular premature contraction [p=0.016; OR=3.29; 95% CI=1.3-8.6] in the Sh group. In terms of the presence or absence of diabetes, dyslipidemia, hypertension, and hyperuricemia, there was no difference between the two groups. One individual from the Sh group was confirmed to have Graves' disease two years later. Conclusion: Since more individuals in the Sh group were thyroid

  19. Significance of lenticular opacity from the view point of the exposure dose of A-bomb radiation

    Two cases of lenticular opacity were discussed from the view point of exposure dose of A-bomb radiation. Case 1: female, 22 year and 5 months old when she was exposured to A-bomb radiation. The presumed exposure dose was 482.0 rad. Cataract due to A-bomb radiation. Case 2: female, 21 years and 6 months old when she was exposured to A-bomb radiation. The presumed exposure dose was more than 1,000 rad. Cataract due to A-bomb radiation and incipient cataract senilis. It was reported here that there was a marked difference in opacity findings of cataract due to A-bomb radiation in accordance with difference in exposure dose of radiation. It was also presumed from the findings of incipient cataract senilis that with increasing exposure dose, the aging phenomenon was promoted. (Y. Tsukamoto)

  20. Secular trends of blood pressure in A-bomb survivors

    There has been controversy about whether or not radiation exposure plays a major role in advancing age. To preliminarily study this relationship, a statistical analysis was made on blood pressure measurements in a cohort of A-bomb survivors for Adult Health Study carried out during a 22-year period from 1958 through 1980. Systolic blood pressure increased with advancing age in both men and women between 30 and 80 years. During the years 1974 through 1980, it tended to increase in both men and women aged in their thirties and fourties. Diastolic blood pressure for men increased between the ages of 30 and 60 years, and decreased between the ages of 60 and 80 years. It tended to increase from year to year for men. For women, it decreased prior to the 1970's, and thereafter, tended to increase. The parameters, including systolic and diastolic blood pressures and pulse pressure, were independent of exposure doses in the subgroups according to age or sex. (Namekawa, K.)

  1. Diagnostics of Ellerman Bombs with High-resolution Spectral Data

    Li, Z; Guo, Y; Chen, P F; Xu, Z; Cao, W

    2015-01-01

    Ellerman bombs (EBs) are tiny brightenings often observed near sunspots. The most impressive characteristic of the EB spectra is the two emission bumps in both wings of the H$\\alpha$ and \\ion{Ca}{II} 8542 {\\AA} lines. High-resolution spectral data of three small EBs were obtained on 2013 June 6 with the largest solar telescope, the 1.6 meter New Solar Telescope (NST), at the Big Bear Solar Observatory. The characteristics of these EBs are analyzed. The sizes of the EBs are in the range of 0.3\\arcsec\\--0.8\\arcsec\\ and their durations are only 3--5 minutes. Our semi-empirical atmospheric models indicate that the heating occurs around the temperature minimum region with a temperature increase of 2700--3000 K, which is surprisingly higher than previously thought. The radiative and kinetic energies are estimated to be as high as 5$\\times$10$^{25}$--3.0$\\times$10$^{26}$ ergs despite the small size of these EBs. Observations of the magnetic field show that the EBs appeared just in a parasitic region with mixed polar...

  2. Small-Scale Structuring Of Ellerman Bombs at Solar Limb

    Nelson, C J; Doyle, J G; Freij, N; Erdélyi, R

    2014-01-01

    Ellerman bombs (EBs) have been widely studied in recent years due to their dynamic, explosive nature and apparent links to the underlying photospheric magnetic field implying that they may be formed by magnetic reconnection in the photosphere. Despite a plethora of researches discussing the morphologies of EBs, there has been a limited investigation of how these events appear at the limb, specifically, whether they manifest as vertical extensions away from the disc. In this article, we make use of high-resolution, high-cadence observations of an AR at the solar limb, collected by the CRISP instrument, to identify EBs and infer their physical properties. The upper atmosphere is also probed using the SDO/AIA. We analyse 22 EB events evident within these data, finding that 20 appear to follow a parabolic path away from the solar surface at an average speed of 9 km s^(-1), extending away from their source by 580 km, before retreating back at a similar speed. These results show strong evidence of vertical motions ...

  3. Serum autoantibodies in atomic bomb survivors, Hiroshima and Nagasaki

    In order to evaluate delayed effects of radiation on humoral immunity, an attempt was made to detect antibodies in the serum of atomic bomb survivors against kidney, liver, and parietal cells from rats. The following results were observed. Comparing by sex and age, the detection frequency of antibodies increased significantly for all three organs in the male group only. Analysis of changes in antibody detection frequencies by age and exposure dose without considering sex showed that the rates for those exposed to 100 + rad showed a trend to increase with age for all three organs (P < 0.01). However, in the 0 rad group, a significant trend to increase with age was noted for antikidney and antiliver antibodies only (P < 0.01 for both). Analysis of changes in antibody detection frequencies by sex, age, and exposure dose showed that the detection frequencies increased significantly with age for all three organs in males exposed to 100 + rad (P < 0.05), but only the antiliver antibody frequency increased significantly with age in males in the 0 rad exposure group. Females failed to show any statistical changes in any exposure group. (author)

  4. Homemade chemical bomb incidents - 15 states, 2003-2011.

    2013-06-21

    Homemade chemical bombs (HCBs) are made from commonly found chemicals. The volume of news reports of HCB explosions suggests they are not uncommon. To determine the number of events involving HCBs in the United States and describe the factors associated with them, the Agency for Toxic Substances and Disease Registry (ATSDR) analyzed data from its surveillance system that tracks spills and leaks of hazardous substances. This report describes the results of that analysis, which indicated that, during 2003-2011, a total of 134 events involving HCBs were reported from 15 states. Among those events, 21 (16%) resulted in adverse health effects (i.e., respiratory symptoms, burns, and skin irritation) for 53 persons. The majority (35 [66%]) of these persons were youths.HCBs are hazardous and especially dangerous if detonated in public areas. Increasing awareness of HCBs and their dangers (particularly during summer months) among first-responders, parents, school staff members and others who work with youths might help reduce injuries associated with HCBs.

It is established that an standard deviation of cooling constant for all calorimeters in direct proportional to standard deviation W. 

  6. The children of parents exposed to atomic bombs

    The data collected in Hiroshima and Nagasaki during the past 40 years on the children of survivors of the atomic bombings and on the children of a suitable control population are analyzed on the basis of the newly revised estimates of radiation doses. No statistically significant effects emerge with respect to eight different indicators. Since, however, it may confidently be assumed some mutations were induced, we have taken the data at face value and calculated the minimal genetic doubling doses of acute radiation for the individual indicators at various probability levels. An effort has also been made to calculate the most probable doubling dose for the indicators combined. The latter value is between 1.7 and 2.2 Sv. It is suggested the appropriate figure for chronic radiation would be between 3.4 and 4.5 Sv. These estimates suggest humans are less sensitive to the genetic effects of radiation than has been assumed on the basis of past extrapolations from experiments with mice. (author) 75 refs

  7. A cytogenetic study of Hiroshima atomic bomb survivors

    A total of 896 metaphases obtained from 2-d-cultures of peripheral blood lymphocytes of 23 heavily exposed A-bomb survivors of Hiroshima were examined first after ordinary staining, and the re-examined after trypsin-G-band staining. The frequencies of cells with radiation-induced chromosome aberrations, mainly of the symmetric type, were compared for the two methods. There were 348 metaphases identified as having abnormal karyotypes by either one or both methods. Of these aberrant cells, 293 were found to have chromosome aberrations by the ordinary stain. There were 55 metaphases in which abnormalities were detected only by G-banding, while 6 cells were identified as abnormal by ordinary stain but as normal by G-banding, 4 of which were misjudged in the ordinary preparation due to the presence of partially distorted chromosomes. Further G-banding analysis identified various exchanges, including several types of insertions and paracentric inversions, which could not be detected by the ordinary staining technique. (author)

  8. The children of atomic bomb survivors: a synopsis.

    Schull, William J

    2003-12-01

    When the atomic bombing of Hiroshima and Nagasaki occurred in the summer of 1945, most members of the public presumed that many of the children conceived by the survivors would be grossly deformed or seriously damaged in other ways as a consequence of radiation-induced mutations. Although the experimental data then available, largely limited to studies of Drosophila melanogaster, the common fruit fly, did not support this perception, the limitations of the data and the depth of public concern warranted a careful follow-up of the children born to the survivors. To this end a surveillance was begun in 1947 of all pregnancy outcomes after 20 weeks of gestation in these two cities. Over the half century subsequent to the initiation of this surveillance, some 80-odd thousand pregnancy outcomes have been studied and a variety of potential indicators of mutational damage measured. This report summarises the findings of these studies and offers an estimate of the genetic risk based on these findings. PMID:14750686

  10. Increased somatic cell mutant frequency in atomic bomb survivors

    Frequencies of mutant T-cells in peripheral blood, which are deficient in the activity of hypoxanthine guanine phosphoribosyltransferase (HPRT) were determined for atomic bomb survivors by direct clonal assay using a previously reported method. Results from 30 exposed survivors (exposed to more than 1 rad) and 17 age- and sex-matched controls (exposed to less than 1 rad) were analyzed. The mean mutant frequency (Mf) in the exposed (5.2 x 10-6; range 0.8 - 14.4 x 10-6) was significantly higher than in controls (3.4 x 10-6; range 1.3 - 9.3 x 10-6), a fact not attributable to lower nonmutant cell cloning efficiencies in the exposed group since cell cloning efficiencies were virtually identical in both groups. An initial analysis of the data did not reveal a significant correlation between individual Mfs and individual radiation dose estimates when the latter were defined by the original, tentative estimates (T65D), even though there was a significant positive correlation of Mfs with individual frequency of lymphocytes bearing chromosome aberration. However, reanalysis using the newer revised individual dose estimates (DS86) for 27 exposed survivors and 17 controls did reveal a significant but shallow positive correlation between T-cell Mf values and individual exposure doses. These results indicate that HPRT mutation in vivo in human T-cells could be detected in these survivors 40 years after the presumed mutational event. (author)

  11. Cancer risk estimation from the A-bomb survivors

    Generalizations regarding radiogenic cancer risks from the A-bomb survivor data of the Radiation Effects Research Foundation involve a large number of well-identified uncertainties and approximations. These include extrapolation to low doses and dose rates, projections in time, sampling variation, the quality of the data, extrapolation to other populations, and the use of simplifying conventions. This paper discusses some of these issues, with emphasis on the first three. Results are given regarding the maximum 'linear-quadratic' curvature consistent with these data, taking into account uncertainties in individual exposure estimates. Discussion is given regarding use of relative risk models and projection of lifetime risks, emphasizing results for those who were old enough at exposure to have been followed up for a major part of their lives by now, and stressing the speculative aspects of conclusions about those exposed as children. Combining these results, and brief discussion of other uncertainties itemized above, comment is made on the evolution of risk estimates over the past 15 years. (author)

  12. Smoking and serum proteins in atomic bomb survivors in Hiroshima

    Associations of smoking habit with serum levels of total protein as well as protein fractions were studied in a population consisting of 4,739 atomic bomb survivors and unexposed control subjects in Hiroshima who participated in the 1979-81 period of the Adult Health Study, an on-going health follow-up program of the RERF. Smoking was strongly related to serum protein concentration after correction for age, sex, and body mass index. Among current smokers as compared to nonsmokers, levels of total protein, β globulin, and γ globulin were significantly lower (p1 and α2 globulin were significantly higher (p1 globulin. Duration of smoking (years) was related to increased α1 and α2 globulin. Smoking duration was also associated with albumin level but the trend was not monotonic. The radiation exposure effect on serum protein level was significant in several instances but was in general much smaller than the smoking effect. Its inclusion in the regression models did not noticeably affect the association between smoking and serum proteins. (author)

  13. Studies of radioactivity produced by the Hiroshima atomic bomb, 2

    Three studies of fallout measurements were reviewed for the discussion of possible radioactivity intake from the Hiroshima atomic bomb. The first study discussed correlations between enriched 234U and 137Cs specific activities from the measurement of soil samples collected in the 'black rain' area. The second study measured 137Cs activity on the rock and roof tile samples collected in the hypocenter area immediately after the explosion. Some of the rock and roof tile samples collected near the hypocenter had a small but detectable amount of 137Cs activity. However, it has been determined that 137Cs exposure, for example, was negligible compared with DS86 dose estimates, since these activity levels were low. The third study detected 90Sr activity in some of the specimens of human bones exhumed on Ninoshima Island. This study compared the difference in activity between the bone head and shaft, with higher activities obtained in the bone head. This fact suggests a short intake period for this activity, however, the levels of 90Sr contamination were too low to allow a discussion of the exposure risks. (author)

  14. The bomb black market - Inquiry about nuclear proliferation

    Nuclear weapons remain for a long time in the hands of the five big powers: USA, Soviet Union, Great Britain, France and China. Things started to change when Israel, and then India acquired the atomic bomb as well. Pakistan took up the race too but Abdul Qadeer Khan, one of the nuclear program maker of the country, took profit of the situation to set up a huge international proliferation network for the spreading of the technologies, tools and materials necessary for weapons fabrication. He offered his services not only to Iran and North Korea, but to Iraq and Libya as well and probably to some other countries. Today, the Iranian nuclear program generates both envy and fear in the Middle East. Who is going to be the next domino of the nuclear game? Egypt, Saudi Arabia, Algeria and Turkey are potential candidates. But while Pakistan sinks into crisis, the terrorists are taking interest in nukes. The author of this book has worked for more than 10 years on this dossier. He has had access to the most sensible documents and to essential testimonies. He now lifts the curtain on the secrets of nuclear proliferation. In this book, where reality sometimes surpasses fiction, he explains how the CIA finally succeeded in infiltrating the 'Khan ring' after having closed its eyes on his deals for a long time. He describes the branches of the Pakistani atomic complex and analyses with lucidity the nuclear terrorism risk

  15. Application of Bomb Radiocarbon Chronologies to Shortfin Mako (Isurus oxyrinchus)

    and the number of samples for MIA analysis was insufficient for some months. Hence, unequivocal validation of shortfin mako age estimates has yet to be accomplished. Atmospheric testing of thermonuclear devices in the 1950s and 1960s effectively doubled the natural atmospheric radiocarbon ({sup 14}C). The elevated {sup 14}C levels were first recorded in 1957-58, with a peak around 1963. As a consequence, {sup 14}C entered the ocean through gas exchange with the atmosphere at the ocean surface and in terrestrial runoff. Despite variable oceanographic conditions, a worldwide rise of the bomb {sup 14}C signal entered the ocean mixed layer as dissolved inorganic carbon (DIC) in 1957-58. The large amounts of {sup 14}C released from the bomb tests produced a signature that can be followed through time, throughout the marine food web, and into deeper waters. The marked increase of radiocarbon levels was first measured in the DIC of seawater and in biogenic marine carbonates of hermatypic corals in Florida. Subsequently, this record was documented in corals from other regions and in the thallus of rhodoliths. The accumulation of radiocarbon in the hard parts of most marine organisms in the mixed layer (such as fish otoliths and bivalves) was synchronous with the coral time-series. This technique has been used to validate age estimates and longevity of numerous bony fishes to date, as well as to establish bomb radiocarbon chronologies from different oceans. In the first application of this technique to lamnoid sharks, validated annual band-pair deposition in vertebral growth bands for the porbeagle (Lamna nasus) aged up to 26 years. Radiocarbon values from samples obtained from 15 porbeagle caught in the western North Atlantic Ocean (some of which were known-age) produced a chronology similar in magnitude to the reference carbonate chronology for that region. The observed phase shift of about 3 years was attributed to different sources of carbon between vertebrae and those for

  16. Autoantibodies and immunoglobulins among atomic-bomb survivors

    The purpose of this study was to determine if exposure to atomic-bomb radiation affects immune responsiveness, such as the occurrence of autoantibodies and levels of immunoglobulins. Rheumatoid factor, antinuclear antibody, antithyroglobulin antibody, anti-thyroid-microsomal antibody, and immunoglobulin levels (IgG, IgM, IgA, and IgE) were measured among 2061 Adult Health Study participants in Hiroshima and Nagasaki from December 1987 to November 1989. The prevalence and titers of rheumatoid factor increased in a statistically significant manner with increasing radiation dose. No radiation effect was found on the prevalence of antinuclear antibody, antithyroglobulin antibody, and anti-thyroid-microsomal antibody. A statistically significant relationship was also found between radiation exposure and the IgA level in females and the IgM levels in both sexes-both levels increased as radiation dose increased. However, the effects of radiation exposure were not large and accounted for less than 10% of the total variation in each measurement. Levels of IgG and IgE were not affected by radiation exposure.

    1989-01-01

    A total of 1424 A-bomb survivors, consisting of 596 men and 827 women, participated in the health screening during the period from August 1985 through March 1988. Abnormal findings of ultrasonography were observed in 64% for men and 53% for women. According to age groups, the incidence of abnormal findings tended to increase with aging in men. In women, it was independent of aging. The most common abnormal finding was billiary calculus (13%), followed by renal cyst, splenomegaly, hepatomegaly, and liver disturbance. Suspected hepatic tumor, hepatomegaly, liver disturbance, fatty liver, and liver cirrhosis were more frequent in men than women. The incidence of billiary or gallbladder calculus was significantly higher in women than men. Among 56 survivors (13%) with suspected malignancy, it was confirmed in 25 survivors (19 with primary or metastatic liver carcinoma, 3 with renal cell carcinoma, 2 with cholangiocarcinoma, and one with pancreatic carcinoma). Of 9 hepatoma patients, 8 had an increased alpha-fetoprotein. Hematologic findings were normal in all of the patients with renal cell carcinoma. (N.K.).

  18. Cell biological study in multiple myeloma among atomic bomb survivors

    The study was undertaken to determine differences in the expression of cell surface antigens in normal plasma cells and mature myeloma cells. The subjects were 20 patients with multiple myeloma, including 5 A-bomb survivors. Seven normal persons, four with chronic tonsillitis, one with idiopathic thrombocytopenic purpura, and two with chronic lymphadenitis served as controls. In the group of myeloma cells, 12 showed mature myeloma cells of VLA-4+/VLA-5+/MPC-1+, and the other 8 showed precursor myeloma cells of VLA-4+/VLA-5-/MPC-1-. In terms of CD56 and CD19, CD56+/CD19- were seen in 13 patients, CD56-/CD19- in 5, and CD56+/CD19+ in 2; none of the patients showed phenotype of CD56-/CD19+. In the control group, all showed VLA-4+/VLA-5+/MPC-1+/CD44+/CD56-/CD19+; phenotype of normal plasma cells was CD38++/CD56-/CD19+ alone, which was not seen in the group of mature myeloma cells. Thus, this type is considered characteristic to normal plasma cells. These findings revealed that the difference in the expression of CD56 and CD19 aids in the identification of myeloma cells from normal plasma cells. (N.K.)

  19. Genetic analysis of children of atomic bomb survivors

    Studies are under way for the detection of potential genetic effects of atomic bomb radiation at the DNA level in the children of survivors. In a pilot study, we have examined six minisatellites and five microsatellites in DNA derived from 100 families including 124 children. We detected a total of 28 mutations in three minisatellite loci. The mean mutation rates per locus per gamete in the six minisatellite loci were 1.5% for 65 exposed gametes for which mean parental gonadal dose was 1.9 Sv and 2.0% for 183 unexposed gamates. We detected four mutations in two tetranucleotide repeat sequences but no mutations in three trinucleotide repeat sequences. The mean mutation rate per locus per gamete was 0% for the exposed gametes and 0.5% for the unexposed gametes in the five microsatellite loci. No significant differences in the mutation rates between the exposed and the unexposed gametes were detected in these repetitive sequences. Additional loci are being analyzed to increase the power of our study to observe a significant difference in the mutation rates at the 0.05 level of significance. 54 refs., 2 figs., 4 tabs

    This document contains 3 reports dealing with the delayed effects of radiation on the eyes of survivors of the atomic explosions in Hiroshima and Nagasaki. In the first study, 1000 persons who were listed as having been in the open and within two kilometers of the hypocenter at the time of the explosion were selected at random from the census files of the Atomic Bomb Casualty Commission for study. In addition, 231 others, comprising the total available number of surviving persons listed at present in the census files as having been within one kilometer of the hypocenter, were examined, as were several hundred others who were contacted through newspaper publicity, referrals from local ophthalmologists, or through hearsay. The survey resulted in bringing in persons having, or having had, a variety of ocular conditions. Those connected with the atomic bomb included the following diagnoses; multiple injuries of eyes and eyelids; keratoconjunctivitis from ultraviolet and ionizing radiations; thermal burn of the cornea and of the retina; retinitis proliferans; and radiation cataracts. The cataracts were the only delayed manifestations of ocular injury from the atomic bomb. The second paper is a case report of a histopathologic study of atomic bomb radiation cataract. The third paper presents the results of medical examinations of survivors having radiation induced cataracts. 32 references, 8 figures. (DMC)
