Summation of pulses in $\gamma$-ray spectra / Gromov, K Ya ; Chumin, V G ; Fominykh, V I ; Samatov, Zh K
It is shown that peaks formed in gamma -ray spectra by summing the pulses due to gamma cascades can be used to determine both the activity of the radiation source and the efficiency of detecting the gamma rays. Possible sources of errors in determining these quantities were investigated. [...]
