模拟化爆爆心土壤中~(239)Pu的分析

Analysis of ~(239)Pu in Simulated Chemical Explosion Core Soil

摘要: 建立了模拟化学爆炸后土壤中239Pu的分析方法,程序包括用沸腾的HNO3-HF混合酸浸取土壤,阴离子交换分离纯化239Pu,脉冲电镀制源,α放射性测量。此方法回收率为77.6%±5.3%。

Abstract: The analysis method of 239Pu in the soil of chemical explosion core is established. The program is HNO3HF mixed acid soaking, anionexchanging and preparing source by pulse platingradioacivity counting. The recovery of the method is 77.6%±5.3%.
