Abstract:

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.

Key words: Kr-88 and Rb-88, Gamma-ray emission probability, Decay relationship, Activity, Peak efficiency
