Research Abstract

1.セミパラチンスク旧ソ連核実験場周辺の村、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、他の村等で土壌を採取し、Cs-137、I-129、Pu、の同位体を測定し結果をまとめた。試料採取は雲の通った跡を調査し、それに垂直に0.5kmから数kmの間隔で行った。これにより雲の通った跡を中心にきれいなピークが観測された。さらに、それぞれの村の被ばく線量を推定した。汚染から直接推定する方法と、下記のシンカレフ氏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り、良い一致を見た。現地担当はナイラ氏、アプサリコフ氏である。
2.測定結果は、Bq/m^2の単位で放射能の降下量として求める。そして正確な村平均の被ばく線量推定のための資料とする。シンカレフ氏とグラフノフスカヤ氏は、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した。今後個人被ばく線量推定のための方式を確立したのでコンピュータ入力する。毎年セミパラチンスクの放射線被ばくに関する研究を中心として、"広島国際シンポジウム"を開催していて、本年は平成23年1月12日に第16回目のシンポジウムを開催し、これらの結果を発表した。線量評価や影響の研究発表を行い討論し、シンポジウムで得られた結論に基づき研究を発展させる。今後は広島の黒い雨の線量とも比較する。黒い雨の線量のワークショップは、本年度1月11日および13日に開催した。これらは昨年と同様である。
3.被ばく者の心的影響、証言等を集めた。被ばくの影響を検討しまとめている。
4.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ている。今後、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ばくの限度を定め、放射線障害防止法の改正を必要とする可能性がある。
