The results of an experimental comparison of algorithms used in radiation monitoring are presented. Serially produced TSRM-type radiation monitors, which are manufactured by the All-Russia Research Institute of Automatics, and radioactive sources are used. The data coming from the monitor’s detector are processed using all algorithms simultaneously in real time. Cases of low and high counts, which conform to Poisson and Gaussian statistics, with average values of about 10 and 100, respectively, are examined. Good agreement is obtained between the experimental and computed data. The probability ratio and a priori probability algorithms give the best results. The use of these algorithms in radiation monitors will make it possible to increase the probability of detecting radiation sources by a factor of 2–3 without increasing the frequency of false alarms.
