Studies on methods on in-situ dose evaluation due to radioactive strontium

用牙齿β计数法对骨中锶蓄积的内照射剂量进行了原位评价。本研究是基于在国外具有代表性的原核危险区调查的方法，不仅对日本人，而且对在日本的外国人进行了门牙β射线测量。在现场向每个受试者解释了结果。所有成员均低于该结果的检测限。制作了三种解释材料，以便公众容易理解辐射照射剂量和健康影响。出版了“前苏联核发展的辐射防护教训”一书。2011年4月以来，福岛核事故的现场剂量学研究已经在国内开展。这有效地揭示了福岛公众的低剂量，并已出版一本书“福岛神话与现实”。

In-situ internal dose evaluation has been studied for strontium accumulated in bone by beta counts on teeth. This research is based on the way developed from investigation in the representative's former nuclear hazard area of foreign countries.Front tooth beta-ray measurement has been carried out not only for Japanese but also for foreigners in Japan. The results were explained to each subject at the place. All the members were below the detection limit for this result.Three kinds of explanation material were made so that the dose of the radiation exposure and healthy influence might be easy to understand for the general public. A book of "Lessons of radiation protection from nuclear developments in the former USSR" has been published. The representative performed some seminars domestic and abroad by using these materials.Internal in-situ dosimetry studies have been carried out for Fukushima nuclear accident since April 2011. This revealed low doses for Fukushima public effectively and has been published as a book "Fukushima Myth and Reality".
