居里级~(242)Cm的制备新工艺

PREPARATION OF 242Cm OF CURIE QUANTITY.

摘要: <正> ~(242)Cm是一种α放射性比度很高(3.3Ci/mg)的核素,所以能应用于国民经济和科学研究。它的制备方法国内外都有报道,但都比较复杂。本文根据近年来的研究成果和制备居里级~(242)Cm的具体要求制订了新的流程。将60mgAmO_2与少量的Al粉混合后制靶,置于我所重水反应堆Φ_(th)=6×10~(13)n/cm~2·s位置照射9.4

Abstract: 242Cm is a highly a radioactive nuclide (3.3 Ci/mg),which has many uses in technique and scientific research, and its preparation in 100 Ci quantity has been reported before in China. A new method of its preparation in curie quantity is here reported consisting of two stepes of chromatography, a TBP extraction and an anion exchange resin.This method is more simple and gives a purer product than the method used before and an advanced γ monitor on line is used.
