Abstract

As the sum-peak method requires the total count rate as well as the peak count rates and the sum peak count rate, this meets difficulties when a sample contains other radionuclides than the one to be measured. To solve the problem, a new method using solely the peak and the sum peak count rates was developed. The method was theoretically and experimentally confirmed using ⁶⁰Co, ²²Na and ¹³⁴Cs. We demonstrate that the modified sum-peak method is quite simple and practical and is useful to measure multiple nuclides.
