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.

从2003年到2004年，这项研究最重要的时刻之一是2005年3月9日至11日在日本科学促销机构支持的在广岛大学举行的研讨会（Dolon Semipalatinsk的第三次国际研讨会）。该研讨会是计划在2002年9月在Semipalatinsk举行的剂量学研讨会之后进行的。演讲为63个，其中包括26位外国发言人。该研讨会的主要主题是Dolon剂量测定法。我们已经进行了2年的研究。主要受试者是1。使用砖样品的热发光剂量法（TLD）的国际比较，2。通过ESR方法进行的牙齿搪瓷剂量测定法，3。从放射性云中计算辐射的计算，4。土壤中放射性的测量和5。染色体的异常检测。总之，TLD表明0.5 Gy，ESR的作用从0,1到0.5 Gy，由于放射性云的变化而导致的计算校正了约0.5 Gy，染色体像差研究尚不清楚，但其中一项研究表明0.3 Gy，这并不矛盾，这与其他结果没有矛盾。由于这些结果，我们可以得出结论Dolon中0.5 Gy，另一方面最有可能的是前者估计从0波动到2 Gy。这是最重要的结果。已经解决了一个主要问题，因此我们应该继续进行个人剂量法。在Semipalatinsk进行的研究是与Yamamoto博士的小组Kanazawa University进行的，并与Takeichi博士的小组在Saljal，Karaul，Kokpecti，Kokpecti和等。与Micro Soto Outro核的伪装异常和收益。 Katayama博士安装了我们的计算机服务器并构建了数据库。
