Changmao Chen, Jianlun Xie. A modified proportional source method used for measuring the dead time of a radiation detecting system[J]. Nuclear techniques, 1986, 09(1): 50-52,63.DOI:
This paper describes a method of measuring the dead time of a radiation detecting system using two radiation sources with the same spectrum and structure but different intensity. It can be used to precisely determine the dead time independent from count rates
and the approximate values of the relative intensities of the sources can be obtained.
