Abstract

Gaseous 125I was present at 48 +/- 33 and 122 +/- 15 kBq in Na125I vials (74 MBq) purchased from Amersham and New England Nuclear, respectively. Gaseous 125I leaked to the amount of 37 +/- 22 and 130 +/- 67 kBq during radioiodination by the chloramine-T and the enzymatic methods using 18.5 MBq Na125I, respectively. Radioactive wastes from radioiodination using 18.5 MBq Na125I evolved about 5.5 kBq of gaseous 125I in first day of storage.

摘要

分别从安玛西亚公司和新英格兰核公司购买的装有碘化钠（74 MBq）的小瓶中，气态碘-125的含量分别为48±33 kBq和122±15 kBq。在使用18.5 MBq碘化钠通过氯胺-T法和酶法进行放射性碘化过程中，气态碘-125的泄漏量分别为37±22 kBq和130±67 kBq。使用18.5 MBq碘化钠进行放射性碘化产生的放射性废物在储存第一天释放出约5.5 kBq的气态碘-125。
