地層処分の安全評価において重要と考えられるRaの鉱物への取り込み現象を理解するために、calciteやwitheriteなどの鉱物を使った再結晶の挙動を調べた。今回の試験ではcalciteに対するCaの挙動とwitheriteに対するBaの挙動を求めた。

Ra-226 is a safety-relevant radionuclide in performance assessments of high-level waste repositories and has thus been deserved special attention. The aim of the proposed study is to provide new key data on the interaction of Ra with calcite and witherite. In this study, the interaction of Ca with calcite and Ba with witherite was measured by using Ca-45 and Ba-133.
