摘要
讨论了电沉积钍同位素α源中２１５Ｐｏ测量中存在的问题。证实了２１５Ｐｏ测量结果偏低的主要原因是２２３Ｒａ的逃逸。
The problems in the determination of 215 Po in electrodeposited thorium isotopic α source are discussed in this paper. The results show that the main cause of the low results for 215 Po is due to the escape of 223 Ra. The sealing film technique is proved to be very effective in solving the problem and has been applied to the determination of 215 Po in electrodeposited thorium isotopic α source.
