强⁶³Ni片状源β粒子发射率的测量方法

摘要: 用于⁶³Ni辐生伏特电池的片状⁶³Ni源β粒子发射率存在难于测量的问题，本文根据闪烁探测器的测量原理建立了闪烁电流法的相对测量方法。利用该测量方法对自制的⁶³Ni源的发射率进行了测量，对所测结果进行了分析，初步认为闪烁电流法是一种用于测量高发射率片状⁶³Ni源β粒子发射率的可行方法。

Abstract: For the problem of measurement difficulties of β particle emission rate of Ni-63 source plate used for Ni-63 betavoltaic battery, a relative test method of scintillation current method was erected according to the measurement principle of scintillation detector.β particle emission rate of homemade Ni-63 source plate was tested by the method, and the test results were analysed and evaluated, it was initially thought that scintillation current method was a feasible way of testing β particle emission rate of Ni-63 source plate with high β particle emission rate.
