摘要
本文研究了从裂变产物中分离提取短寿命核素 13 8Cs的方法。通过两步沉淀和一步溶剂萃取 ,实现13 8Cs与其他裂片核素的分离。 γ能谱分析表明 ,13 8Cs对其他裂片核素的去污系数 >10 3 ,13 8Cs的化学回收率为 4 5 .0 %。
A procedure for separating short-lived 138Cs from fission products has been investigated. With two steps precipitations and a solvent extraction, 138Cs can be isolated from fission products.Based on the Analysis of γ spectrometry, the decontamination factors of 138Cs for other fission products are larger than 10 3 and the procedure recovery of 138 Cs is 45.0%.
