    Introduction: Lengthy clinical and epidemiological studies at the Research Institute of Radiation Medicine and Ecology have discovered basic patterns of long-term effects from ionizing radiation in population groups exposed to radiation risk. Methodology for calculating injury from radiation risk factors has been developed and implemented to minimize the effects of the Semipalatinsk nuclear test site (SNTS).Material and methods: We analyzed materials from the database of the Scientific Medical Register that were exposed to radiation as a result of SNTS. We analyzed both male and female populations of the Abay, Beskaragai and Zhanasemei, Kokpekti (control) areas of East-Kazakhstan region (EKR) from 2008-2012. These populations were split into three groups allocated by the generation. The first group represented persons born from the period of 01/01/1930 -08/01/1949 and their children born from the period of 10/09/1949-12/31/1962. The second group were persons born after 01/01/1963. The third group served as the control and were persons who immigrated to these areas after 1990.Results: There was an increased incidence of cancer (21.5%, p < 0.000734), cardiovascular diseases (10.2%); respiratory problems (9.6%), gastrointestinal issues (9.1%, p < 0.00371-0.00679) in the first group. The effect of the radiation dose has not been fully stuided among the subjects in the second group.The major causes of excess mortality in the first group were neoplams (30.6%), hypertension (23.8%), and myocardial infarction (22.6%). The effects of radiation influenced mortality in the second group were 2-2.5 times lower than the first group.Conclusion: There is a correlation between the size of the radiation dose, the risk profile, and age at the moment of radiation exposure with trends of morbidity and mortality in the radiation exposed areas

    The nuclear bomb testing conducted at the Semipalatinsk nuclear test site in Kazakhstan is of great importance for today’s radiation protection research, particularly in the area of low dose exposures. This type of radiation is of particular interest due to the lack of research in this field and how it impacts population health. In order to understand the possible health effects of nuclear bomb testing, it is important to determine what studies have been conducted on the effects of low dose exposure and dosimetry, and evaluate new epidemiologic data and biological material collected from populations living in proximity to the test site. With time, new epidemiological data has been made available, and it is possible that these data may be linked to biological samples. Next to linking existing and newly available data to examine health effects, the existing dosimetry system needs to be expanded and further developed to include residential areas, which have not yet been taken into account. The aim of this paper is to provide an overview of previous studies evaluating the health effects of nuclear testing, including some information on dosimetry efforts, and pointing out directions for future epidemiologic studies

    Interview Survey on Parents and Children in the Semipalatinsk Area: Perceived Causality between Children’s Diseases/Disabilities and Nuclear Tests

    We interviewed children with diseases and/or disabilities and their parents from nine families in the Semipalatinsk Area from 2009 to 2013. Whether their disabilities/diseases were officially certified or not, most parents pointed to the nuclear tests at the Semipalatinsk Site as the cause of their children’s health problems. Reasons given by the parents for linking the children’s medical problems to Nuclear Tests were classified into three categories: The grandparents of the children had been exposed to radiation directly; the parents themselves grew up in a contaminated area; the area that they currently reside is contaminated and their children are being affected directly. We also explored whether the sense of guilt felt by the parents was eased when their children’s ill health was officially certified as caused by nuclear tests. A detailed analysis of the survey responses revealed that these parents tend to blame themselves for their children’s ill health, regardless the circumstances, and were left thinking ‘if only there were no nuclear tests’. Exploring such layers of thought would shed light on the reality of adverse mental effects on the Semipalatinsk nuclear test site victims.本稿は日本学術振興会科学研究費補助金【基盤C】(平成20-22年度)『セミパラチンスク地区の核被害実態調査研究: アンケート・証言・遺伝子解析を通して』(研究代表者:川野徳幸)、【基盤B】(平成23-25年度)『カザフスタン共和国セミパラチンスク地区住民の被ばく被害に関する総合的研究』(研究代表者:川野徳幸)、【基盤B】(平成27-30年度)『被ばく被害の国際比較研究:セミパラチンスク、チェルノブイリ、広島・長崎、福島』(研究代表者:川野徳幸)の研究成果の一部である。 また本稿は、日本平和学会2016年度秋季研究集会での報告に加筆修正を行ったものである

    Outline of the Law on Social Protection of Citizens Suffered from Nuclear Tests in Semipalatinsk Conducted by the Former Soviet Union

    The former Soviet Union conducted totally 456 nuclear tests between 1949 and 1989 in Semipalatinsk, Republic of Kazakhstan. What does a state support system exist to the people suffering the Semipalatinsk nuclear testing by the former Soviet Union? This paper analyzes a law on social protection of citizens suffered from nuclear tests in Semipalatinsk which Republic of Kazakhstan established in 1992 and revised in 2013. It prescribes the main measures Kazakhstan state provides social benefits and protection to people who suffered from the atomic / hydrogen bombs tests. Based on the social protection act, the present paper aims to describe the outline of the welfare support system to the survivors of the Semipalatinsk nuclear explosions with the view of comparison with Atomic Bomb Survivors' Assistance Act in Japan. In the beginning, we discuss the legal recognition where are environmental affected zone and who are the nuclear suffers. Then we introduce the state support system for victims of the nuclear tests in Kazakhstan based on the law.本稿は、科学研究費(26301003 及び15H03137)による研究成果の一部である

    Nuclear abnormalities in aspirated thyroid cells and chromosome aberrations in lymphocytes of residents near the Semipalatinsk Nuclear Test Site

    Get PDF
    Chromosomal studies in peripheral lymphocytes from 63 residents near the Semipalatinsk nuclear test site, at ages of 52–63 years old, were performed in 2001–2002. A higher rate of chromosome aberrations was observed in the two contaminated villages, Dolon and Sarjal, compared with the control village, Kokpekti. Moreover, a relationship of frequency of cells with radiation induced chromosome aberrations and the previously estimated exposure dose was observed. Furthermore, apparent nuclear abnormalities (ANA) of thyroid follicular cells were studied in 30 out of 63 residents, who were examined for chromosome aberrations. A higher rate of ANA was also found in the residents in the exposed villages compared with those in the control village. These results suggest radiation effects both on the chromosomes in peripheral lymphocytes and on the follicular cells in the thyroid

    The town of Kurchatov was a secret city newly built in the Semipalatinsk nuclear test site as the headquarters of the nuclear tests. The present paper is a pilot study, first, to explore how the current Kurchatov residents think and feel about nuclear weapons and nuclear tests, and secondly, to compare the results of the survey with those of the similar survey near Semipalatinsk. Though the present study is based upon a small and limited survey conducted in the city, it is hoped that it will shed some new lights on the residents' attitudes toward nuclear tests and nuclear weapons. It is shown that the negative attitudes toward nuclear weapons and nuclear tests of those exposed to radiation near Semipalatinsk which characterize the Semipalatinsk survey are shared by the majority of the respondents of Kurchatov, as well as the concerns about the adverse health effects of nuclear tests. It is also shown, however, that there is a striking pro-nuclear minority in Kurchatov. Though the small and limit nature of our data does not allow us to confirm the existence of such a minority, our result suggests a possibility that there may be a certain pro-nuclear minority even in the region which have been severely affected by nuclear tests

    A full-text english database of testimonies of those exposed to radiation near the Semipalatinsk nuclear test site, Kazakhstan

    The present paper is a sequel to the initial report (Kawano et al 2003a) of the project for a full-text Japanese database of the testimonies of those exposed to radiation near the nuclear test site of Semipalatinsk, Kazakhstan. 139 testimonies were gathered in four villages near Semipalatinsk in 2002. We translated them into English from Russian and Kazakh, and created a full-text database by using a Latin script text retrieval program, TERESA. The present paper attempts at essentially the same thing as our first report mentioned above, using the English version of the database. We attempt to show how the database can be used to understand tragic realities of the effects of exposure to radiation from nuclear tests. In the attempt, we try to demonstrate that radiation exposed residents near the test site are affected physically and mentally, by citing retrieved testimonies which complain of illness and bad health, environmental pollution, and mental disorder, resulting finally in suicide. We also try to demonstrate differences between experiences in Semipalatinsk, and those in Hiroshima and Nagasaki. Besides, we add our conceptual and methodological premises for conducting this kind of research, as well as some new findings concerning the radiation exposure in Semipalatinsk
