Conclusions
1. Semiconductor spectrometry of the γ radiation facilitates the analysis of the radiation conditions in nuclear reactors for power generation and research:
identification of the γ radiation sources (radionuclides, nuclear reactions); and
quantitative determination of the intensity of the γ radiation from the identified radionuclides and from nuclear reactions in units of H.
2. The information makes it possible to determine the origin of the radioactive contamination by man-made radionuclides on industrial sites and the degree of radionuclide migration and allows a comparison of the radiation conditions on inspected objects.
3. The total H values of the monoenergetic γ radiation do not exceed 25% of the maximum admissible amounts in the reactor halls inspected [4].
