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 γ-rays were calibrated. The results show that the absolute probabilities of 196.3, 834.8,1529.8, 2195.8 and 2392.1 keV γ-rays of ⁸⁸Kr were 25.1(5)%, 12.9(2)%,10.7(2)%,13.3(2)% and 34.9(5) %, respectively.
