摘要: 针对气体裂变产物中微量77Kr的测量问题,利用MCNP模拟计算了气体裂变产物对77Kr的影响。结果表明,HPGe不可能直接测量气体样品中的77Kr,但可通过测量其子体77Br来推算77Kr。Abstract: The influence of gaseous fission products on the trace 77Kr measurement by HPGe was analyzed by applying MCNP. The results show that the direct measurement of 77Kr in the gaseous sample is impossible. 77Br, the daughter of 77Kr, can be determined by HPGe.
