RÉSUMÉ

Results are presented of our studies of the response threshold as a sensitivity characteristic of the transport radiation monitoring system (RMS) as a whole to gamma-emitters and fissionable materials. The detector of the system is made on the basis of a plastic scintillator with the total volume ∼160 dm3 and frontal area S ∼ 50 dm2. The RMS response threshold values were determined experimentally for gamma-emitters Co-60, Cs-137, Th-232. The RMS response threshold was considered as function of the mean-weighted energy of the detected radionuclide. Estimates were made of SRM response threshold values for radionuclides U-235, U-238, Pu-238. Limiting masses of nuclides and fissionable materials corresponding to the RMS response thresholds, were estimated.
