Includes bibliographic references: p. 31. "The detection of Special Nuclear Material (SNM), and in particular, its stand off detection, represents one of the greatest challenges for radiation and nuclear defence, due to the very low emission rates of gamma rays and neutrons which are often involved. For some scenarios, long passive radiation measurements at short distances can be considered as an option for the detection of SNM devices. In this document, techniques developed to simulate the emission, propagation and detection of photon radiation from SNM are investigated, using a ThermoTM RadEyeTM GN+ non-spectroscopic detector sensitive to both photons and neutrons. Parameters under which SNM detection is possible are also studied"--Abstract, p. i. Includes abstract in French. gccst Nuclear weapons gccst Military technology Nuclear defence Defence R&D Canada.
