Abstract

Dead time is one of several major parameters of a nuclear radiation measurement system. To estimate the dead time and its uncertainty for the TCS-172 gamma survey meter at the Training Center of the Nuclear Research Institute, we conducted 240 count rate measurements using the two-source method with the non-paralysable model and two standard radioactive sources, Cs-137 and Co-60. The results indicate that the dead time for this instrument was 11.29 µs, with an uncertainty of ±1.01 µs. These values align closely with those presented in the textbook and several articles.
