Abstract

Issues in enhancing the precision of the determination of the mean energy and the type of energy distribution (spectrum form) of neutrons from Sb–Be and Ra–Be sources were examined. The specified photoneutron sources were used to calibrate the energy scales of neutron spectrometers and determine the energy dependence of the sensitivity of neutron radiometers and dosimeters. A technique is proposed for calculation of the energy spectra of radionuclide sources of neutrons of the Sb–Be (γ, n) and Ra–Be (γ, η) types, and the calculation results are presented. The dependence of the source spectrum on its design was researched. The correctness of the results of the calculation of the power spectra of radionuclide sources was confirmed experimentally. The obtained data will be required for the determination of the power dependence of the sensitivity of neutron spectrometers, radiometers, and dosimeters.
