Current Characteristics of Ionizing Radiation Fields of the IBR-2 Reactor’s Irradiation Facility for Researching Materials’ Radiation Resistance
The current characteristics of the ionizing radiation fields of an irradiation facility intended for studying the radiation resistance of materials on channel no. 3 of the IBR-2 reactor are presented. Flux densities of fast neutrons for the power of 1.55 MW of the IBR-2 reactor are refined. For the...

description | The current characteristics of the ionizing radiation fields of an irradiation facility intended for studying the radiation resistance of materials on channel no. 3 of the IBR-2 reactor are presented. Flux densities of fast neutrons for the power of 1.55 MW of the IBR-2 reactor are refined. For the first time, the values of absorbed γ-radiation doses have been experimentally obtained. Values exceeding the range of absorbed doses measured by the dosimeters near the IBR-2 water moderator were calculated by the Monte Carlo method. Devices and methods for quantifying characteristics are described. The range of fast neutron densities along the irradiation facility was 3 × 10
