In this scientific research, the definition of appropriate neutron shielding
parameters is presented and the results of calculations or measurements of these
parameters are presented for four selected types of concrete that are used in
protection against neutron radiation. A method for calculating the fast neutron
effective removal cross section is considered, which has its own specificities
because it takes into account different types of interactions of fast neutrons with
the materials from which the selected types of concrete are made. In addition, the
values of macroscopic neutron absorption cross section for thermal neutrons,
macroscopic neutron scattering cross section and total macroscopic neutron
attenuation cross section, which includes scattering of fast neutrons and
absorption of thermal neutrons, are presented for the selected types of concrete.
Based on the analysis of neutron shielding parameters, type of concrete with
coarse-fine aggregate limonite-limonite h...as a higher level of ability to protect
against neutron radiation compared to concrete with coarse-fine aggregate
magnetite-limonite and concrete with barite-barite.
