Abstract

The Ra standardization method is based on the removal of Rn by intensive venting and subsequent separation of radon daughter decay products on a column packed with lead filings, Ra remains in the eluate. The eluate was repeatedly measured by LSC, and the measured values were corrected for the increase in the activity of the Ra daughter products since the separation was completed. The method was applied to EB type solutions from CMI production. The Ra activity was determined with an uncertainty better than 0.6.

摘要

镭标准化方法基于通过强化通风去除Rn，然后在填充有铅屑的柱子上分离氡子体衰变产物，镭残留在洗脱液中。洗脱液通过液体闪烁计数法（LSC）反复测量，测量值根据自分离完成以来镭子体产物放射性活度的增加进行修正。该方法应用于 CMI 生产的 EB 型溶液。镭的活度测定不确定度优于 0.6。
