【摘要】 鉴别测量未知放射性核素在核保障中是十分必要的。论文介绍了用γ能谱法鉴别测量放射性核素的基本原理,探讨了定量测量的主要影响因素,鉴定分析了铝块样品中未知放射性核素种类及其量。经一定时间间隔后,再次测量该样品的结果与理论推算值一致,验证了方法是可靠的。更多还原

【Abstract】 It is necessary to discriminate and determine unknown radionuclide in nuclear safeguard.The basic principle of γ spectrometry for unknown radionuclide discrimination and measurement has been recommended.The main influence factors of radionuclide measurement have been discussed.The species and content(quantity) in a aluminium wafer have been authenticated.The sample has been determined in interval again,the results are consistent with theory calculation results.It validates that the method is reliable.更多还原
