Research Abstract

1.ドロン、セミパラチンスク、ズナメンカ、サルジャル、カイナル、カラウル、他7つの村等で土壌を採取し、Cs-137、Puの同位体を測定中である。これらから、それぞれの村の被ばく線量を推定する。汚染から直接推定する方法と、下記のShinkarevのグループの原爆の雲の通過から計算する方法との両方による。
2.以上を現地担当者Nailya氏(現地海外担当:研究協力者)と検討し決定する。
3.健康調査の問診表を使って、調査内容の全体的な検討を行った。今後の継続について検討する。
4.上記を正確な村平均の被ばく線量推定のための基礎資料とする。Shinkarev氏は、チェルノブイリでの線量評価方式に準じてセミパラチンスクでの個人線量評価方法を確立する。アンケート調査を実施し、個人被ばく線量推定のための方式を確立する。平成17年3月および平成20年2月に広島で開催されたドロンやセミパラチンスク核実験場周辺の村の線量を中心とした国際ワークショップで得られた結論に基づき研究を進めている。今年度も、3月26日に開催した。今後は広島の黒い雨の線量とも比較する。
5.その他、現地で採取できた試料については、日本に持ち帰り測定する。それらは、土壌以外に、歯、血液である。今回は特にI-131(半減期8.0日)の線量評価のため、同位体であるI-129(半減期1.6×10^7年)の測定を引き続き試みる。
6.被ばく者の心的影響、証言等を集め被ばくの影響を検討する。
7.現地にすでに存在している検診データのコンピュータ入力を引き続き進め、方法、計画の検討を行う。最終的には、個人被ばく線量の推定の結果を入力し、低線量率被ばくのリスクの計算を行う。この結果は放射線の被曝の限度を定め、放射線障害防止法の改正を必要とする可能性があり、重要である。
