摘要
In preparation of homogeneous Kr and Rb sources,the Kr activity was determined by the decay relationship between ^(88)Kr and ^(88)Rb using an HPGe detector.The peak efficiencies of ^(88)Kr and ^(88)Rbγ-rays were calibrated.The results show that the absolute probabilities of 196.3,834.8,1529.8,2195.8 and 2392.1 keVγ-rays of ^(88)Kr were 25.1(5)%,12.9(2)%,10.7(2)%,13.3(2)%and 34.9(5)%,respectively.
In preparation of homogeneous ^88Kr and ^88Rb sources, the ^88Kr activity was determined by the decay relationship between ^88Kr and ^88Rb using an HPGe detector. The peak efficiencies of ^88Kr and ^88Rb 7-rays were calibrated. The results show that the absolute probabilities of 196.3, 834.8,1529.8, 2195.8 and 2392.1 keV 7-rays of 88Kr were 25.1（5）%, 12.9（2）%,10,7（2）%,13.3（2）% and 34.9（5） %, respectively.
