State Primary Special Standard of the Unit of Absorbed Dose Rate of Intense Photon, Electron, and Beta Radiation for Radiation Technologies get 209-2014

Spectral, dosimetric properties and metrological characteristics of different radiation sensitive compositions have been investigated for the radiation absorbed dose measurement instrumentation development purpose. It is shown possibility for absorbed dose measurements dynamical range expansion and uncertainty reduction for those compositions. These results can be used for routine dosimetric process control and metrological support in food stuff, agricultural commodities radiation processing technologies.

The results of metrological studies of the field of the experimental channel of the research nuclear reactor OR (experimental base of the NRC “Kurchatov Institute”) with a capacity of 0.1–300 kW are presented. The empirical dependence of the contribution of the absorbed dose of gamma radiation during the raising and lowering reactor power in the total absorbed dose during the irradiation in the reactor and absorbed dose rate from a power reactor OR in the steady state. Based on these results, the absorbed dose and absorbed dose rate of gamma radiation can be pre-calculated. According to metrological studies results, the experimental channel of the reactor OR was certified in terms of the absorbed dose rate of gamma radiation as a specialized source of gamma radiation spatially combined with the modeling reference field of neutrons. The specialized source is designed for calibration of special-purpose measuring instruments and testing for radiation resistance of products operating in conditions of mixed gamma-neutron radiation of nuclear reactors.
