Dosimetry and diseases among residents near Semiparatinsk

自1995年以来，位于哈萨克斯坦共和国北部塞米巴拉金斯克地区的辐射生物和医学研究所、广岛大学和哈萨克斯坦辐射医学和生态科学研究所一直在合作研究核武器试验后的放射性尘埃对人口的影响。迄今为止，所有发表的关于核武器试验场附近人口的辐射影响的报告都是基于前苏联社会主义共和国国防部提供的数据。我们专注于塞米巴拉金斯克试验场附近人群中的辐射剂量测定和相关疾病。1995年和1996年，日本小组在古谢夫博士的指导下访问塞米巴拉金斯克测量土壤和砖的样本。每个重约100公斤的样品被带回广岛进行了测量。多伦是我们研究过的聚落中剂量最高的聚落，剂量为89cGy.这与之前的报告情况类似。塞米巴拉金斯克市在本研究的住区中显示出第二高的剂量。这与之前的报告完全不同。这座城市是核试验场附近最大的城市。由于这个城市的人口是35万，这个值是严重的。需要进一步的调查才能证实这一点。

The effects of radioactive fallout following nuclear weapon tests on the population in the Semipalatinsk region, which is located in the northern part of the Kazakhstan Republic have been studied by a collaboration between Research Institute for Radiation Biology and Medicine, Hiroshima University and Kazakhstan Scientific Research Institute for Radiation Medicine and Ecology since 1995.To date, all of the published reports concerning to the effects of radiation on populations near nuclear weapon test sites are based on data provided by the Defense Department of the former Union of Soviet Socialist Republics. We are focusing on radiation dosimetry and associated diseases in the population near the Semipalatinsk test site.In 1995 and 1996 Japanese group visited Semipalatinsk to measure and to sample soil and brick according to the guidance of Dr.Gusev. The samples which weighted about 100 kg each were brought back to Hiroshima and have been measured.Dolon is the settlement with the highest dose of 89 cGy among the settlements where we have researched. This is the similar situation to the previous reports. Semipalatinsk city exhibits the secondly highest dose among settlements of the present study. This is completely different from the previous reports. This city is the biggest city near Nuclear test site. Since the population of the city is three hundreds and fifty thousand, this value is serious. The further investigation will be needed to confirm this.
