Dosimetry and diseases among residents near Semiparatinsk

自1995年以来，广岛大学放射生物学和医学研究所与哈萨克斯坦放射医学和生态学科学研究所合作，研究了核武器试验后放射性沉降物对位于哈萨克斯坦共和国北方的塞米巴拉金斯克地区人口的影响。所有已发表的关于核武器试验场附近居民受辐射影响的报告都是根据前苏维埃社会主义共和国联盟国防部提供的数据编写的。1995年和1996年，日本一个小组访问了塞米巴拉金斯克，根据Gusev博士的指导，对土壤和砖块进行测量和取样。每个样品重约100 kg，带回广岛进行测量，多隆是我们所研究的居民点中剂量最高的居民点，达89 cGy。这与前几次报告的情况相似。塞米巴拉金斯克市的剂量在本研究的住区中位居第二。这与以前的报告完全不同。这个城市是核试验场附近最大的城市。因为这个城市的人口是35万，这个值是严重的。需要进一步的调查来证实这一点。

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.
