Measurement of Emission Probability of 87Kr
-
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87Kr γ射线发射几率。其中，402.6 keV γ射线发射几率的测量结果为（49.9±1.2）％。Abstract: 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.
