Mechanism of heat production in the plutonium components irradiated by the 252Cf neutron sources was analyzed. The fission heat powers of the plutonium components and the heat powers for the deposited energy of the γ ray from the 252Cf sources were calculated with the Monte Carlo (MC) simulation. The appropriate calculation model was built and the decay heat from the plutonium components was computed. Compared with the spontaneous decay heat power, the heat effects are minor for the neutron sources of typical intensity. Using the approximate model of the delayed γ spectrum, the external radiation doses absorbed by the anthropomorphic phantoms were calculated. Compared with the dose threshold proposed by the International Commission on Radiological Protection (ICRP), the doses absorbed by the operators for the neutron sources of typical intensity are in the safety range. © 2016, Editorial Board of Nuclear Electronics & Detection Tech.

Experimental work in which the energy and efficiency calibration of a CdTe detection system by using standard γ radiation sources is introduced in detail, and at the same time, performance test (such as energy resolution and stability of the system) is also conducted. As a summary, some issues that deserve attention in the application of the CdTe system are discussed.
