Technological overcoming of the potential threat of a decrease in the quality of radiation monolithic structures of protective shields, which are under constant influence of ionizing radiation (due to radiation embitterment) is one of the most urgent tasks of ensuring protection against radiation exposure.
The aim of the work is to carry out a comparative analysis of the quality (in terms of radiation protection) of monolithic and granular protective screens. In contrast to monolithic prototypes, granular conglomeration has clear advantages, which are to avoid destructive processes of radiation embitterment, simplify replacement and handling (compaction and compaction), and disposal. It is important to emphasize that the protective properties of granular screens hardly differ from their monolithic counterparts, and the economic advantages of the corresponding technologies are significant at the same time. The material provided is actually the formulation of the problem on the theoretical substantiation of the advantages of using granular materials (in comparison with monolithic ones) in radiation protection technologies based on analysis as physical mechanisms and form factors of interaction neutron and gamma radiation with a substance with a developed morphology on a micro-scale.
