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

通过对牙齿进行β计数，研究了锶在骨内积累的原位内剂量评价。本研究是在借鉴国外有代表性的原核危险区调查的基础上发展起来的。不仅对日本人，在日本的外国人也进行了门牙射线测量。在现场向每位受试者解释了结果。所有成员均低于该结果的检测限。为了使公众更容易理解辐射照射的剂量和对健康的影响，提出了三种解释材料。一本题为“前苏联核发展的辐射防护教训”的书已经出版。该代表利用这些材料在国内外举办了一些研讨会。自2011年4月以来，已对福岛核事故进行了内部原位剂量学研究。这有效地揭示了福岛公众的低剂量，并出版了《福岛神话与现实》一书。

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".
