摘要 用相对效率为60%的HPGe探测器测量。^87Kr的相对γ射线发射几率和用内充气正比计数管绝对测量。^87Kr放射性浓度。实验上测得了。^87Krγ射线发射几率。其中,402.6keVγ射线发射几率的测量结果为(49.9±1.2)%。 The relative gamma ray emission probabilities of ^87Kr were measured by HPGe detector. The activity concentration of ^87Kr was determined by using internal gas proportional counting system. The 402.6 keV γ-ray emission probability (49.9± 1.2) was obtained experimentally.
