In March 2005, we hold the international workshop at Hiroshima University. The results were published in the supplement of the Journal of Radiation Research Vol. 47 sup. Al-A224 (29 papers). There was a large difference in the estimations of radiation doses by different methods. We discussed about the Dolon village study. They were 1. TLD measurements using brick samples, 2. ESR measurements using tooth enamel samples, 3. Calculation of dose from radioactive clouds, 4. Cs-137 measurements in soil samples and dose calculation, 5. Chromosome aberration study. In conclusion, the results are about 0.5 Gy by TLD, from 0.1 to 0.5 Gy by tooth enamel measurements, about 0.5 Gy from Cs measurements in soil, and about 0.5 Gy by calculation. These values became agree each other. Thus, the contradiction was solved. In addition, chromosome aberration study suggests about 0.3 Gy, which showed also no contradiction. The former values schattered from 0 to 2 Gy but this became close each other about 0.5 Gy for the people outside. The radioactive clouds passed near Dolon village. The distance from the center of the trace to the village was found to be very sensitive. Therefore samples were collected across the trace of the radioactive cloud perpendicularly to the trace over about 10 km length. Tooth enamels are collected and measured. Blood samples are corrected and chromosome aberration and a spot mutation in the genes were studied. Questionnaire for individual dosimetry was made and used for the people there. Another questionnaire was taken to study the mental effects and to collect testifies from the people living in this area. Now data base had been constructed and this is almost finishing. Our future tasks are to estimate the individual doses and the radiation risks using them. The radiation risk estimation is started with Germany group.

2005年3月，我们在广岛大学举办了国际研讨会。研究结果发表在《辐射研究杂志》第47卷增刊上。Al-A224（29篇论文）。不同方法对辐射剂量的估算存在较大差异。我们讨论了多隆村的研究。他们是1。使用砖样进行的重复测量，2. ESR测量使用牙釉质样品，3。放射性云剂量的计算，4。土壤样品中Cs-137的测量和剂量计算，5。染色体畸变研究。总的来说，通过放射性测量，结果约为0.5戈伊，通过牙釉质测量，结果在0.1到0.5戈伊之间，通过土壤中Cs测量，结果约为0.5戈伊，通过计算，结果约为0.5戈伊。这些价值观变得彼此一致。矛盾就这样解决了。此外，染色体畸变研究表明约为0.3戈伊，这也表明不矛盾。前者的值在0 ~ 2戈伊之间，而对于外界的人来说，这两个值在0.5戈伊左右变得很接近。放射性云团经过多隆村附近。从痕迹中心到村庄的距离被发现是非常敏感的。因此，在放射性云迹线上垂直于该迹线收集了约10公里长的样品。收集并测量牙釉质。对血样进行校正，并研究染色体畸变和基因中的点突变。编制个人剂量学调查表，并对现场人员进行了调查。另一份问卷调查研究了心理影响，并收集了生活在这个地区的人的证词。目前数据库已经建成，即将完成。我们未来的任务是利用这些数据来估计个人剂量和辐射风险。辐射风险评估从德国组开始。
