项目摘要

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.

2003年至2004年期间最重要的研究活动之一是2005年3月9日至11日在广岛大学举行的研讨会（第三届多隆塞米巴拉金斯克剂量测定国际研讨会），该研讨会得到了科学促进机构的支持在日本。该研讨会是继 2002 年 9 月在塞米巴拉金斯克举办的剂量学研讨会之后计划举办的。共有 63 场演讲，其中包括 26 名外国演讲者。本次研讨会的主题是 Dolon 剂量测定。我们已经进行了两年的研究。主要课题有：1.砖样热释光剂量测定（TLD）的国际比对；2.ESR法牙釉质剂量测定；3.放射性云辐射的计算；4.土壤放射性测量；5.染色体畸变检测。总之，TLD指示0.5 Gy，ESR从0.1到0.5 Gy，由于放射性云中心的变化而校正的计算结果约为0.5 Gy，染色体畸变研究尚不清楚，但其中一项研究表明0.3 Gy，这与其他结果并不矛盾。根据这些结果，我们可以得出结论，Dolon 的可能性最大为 0.5 Gy，而之前的估计则在 0 到 2 Gy 之间波动。这是最重要的结果。主要问题已经解决，我们应该进行个人剂量测定。在塞米巴拉金斯克的研究是与金泽大学Yamamoto博士小组一起进行的，在Saljal、Karaul、Kokpecti等地与Takeichi博士小组一起进行了检查。染色体畸变和产量田中博士的小组也对微核进行了研究。 Katayama博士安装了我们的计算机服务器并构建了数据库。
