Dosimetry study and radiation effects for the residents near Semipalatinsk nuclear test site

这项研究在2003年至2004年期间最重要的场合之一是2005年3月9日至11日在广岛大学举行的研讨会(第三届多伦塞米巴拉金斯克剂量学国际研讨会)，该研讨会得到了日本科学振兴机构的支持。该讲习班是在2002年9月在塞米巴拉金斯克举行的剂量学讲习班之后计划的。共有63人发言，其中包括26名外国发言者。这次研讨会的主要议题是Dolon剂量学。我们已经进行了两年的研究。主要内容有：1.砖样品热释光剂量学国际比对；2.牙釉质ESR剂量测量；3.放射性云辐射计算；4.土壤放射性测量；5.染色体畸变率检测。结果表明，TLD为0.5GY，ESR为0.1~0.5Gy.由于放射云中心的变化，修正后的计算结果约为0.5Gy.染色体畸变研究尚不清楚，但其中一项研究的结果为0.3Gy.这与其他结果并不矛盾.根据这些结果，我们可以得出结论，从另一方面来说，Dolon最有可能是0.5Gy射线，以前的估计在0到2Gy之间波动。这是最重要的结果。主要问题已经解决，因此我们应该着手进行个人剂量测量。在塞米巴拉金斯克的研究是与山本博士的研究小组金泽大学进行的，与武一博士的研究小组在Saljal，Karaul，Kokpeti等地进行了检查。片山博士安装了我们的计算机服务器并构建了数据库。

One of the most important occasion of the study within the years from 2003 to 2004, is the workshop (3rd international workshop for the dosimetry in Dolon Semipalatinsk) held at Hiroshima University on 9-11 March, 2005, which was supported by Science promotion agency in Japan. This workshop was planned after the dosimetry workshop which was held in Semipalatinsk in September 2002. The presentations were 63 including 26 foreign speakers. The main topic of this workshop was the Dolon dosimetry. We have been performed research for 2 years. The major subjects are 1. international intercomparison of thermoluminescence dosimetry (TLD) using brick samples, 2. tooth enamel dosimetry by ESR method, 3. calculation of radiation from radioactive clouds, 4. measurements of radioactivity in soil and 5. chromosome aberration detection. In conclusion, TLD indicates 0.5 Gy, ESR does from 0,1 to 0.5 Gy, the calculation corrected due to the change of the center of radioactive clouds resulted in about 0.5 Gy, the chromosome aberration studies were not clear but one of the study indicated 0.3 Gy, which was not contradict to the other results. Due to these result we can conclude 0.5 Gy in Dolon is most probable on the other hands the former estimations fluctuated from 0 to 2 Gy. This is the most important result. The major problem has been solved therefore we should proceed to personal dosimetry.The study in Semipalatinsk was performed with Dr.Yamamoto's group, Kanazawa University, examined with Dr.Takeichi's group in Saljal, Karaul, Kokpecti and etc. The chromosome aberration and yield of micro nuclei have been studied with Dr.Tanaka's group also. Dr.Katayama installed our computer server and constructing databases.
