摘要

The FJ-2603 type α β flow level radioactive measurement apparatus were employed. The instrument isrectified by using the 239Pu source and the α efficiency is 44%. The instrument is rectified by the 90Sr-90Ysource and the βefficiency is 22.5%. Measuring time is 1000min. The activity consistency was c
