The work is devoted to the analysis of the transportation features of isotopic fast neutrons sources from the point of view of the used radiation-shield materials and their compositions. A three-dimensional model of the portable container of the packaging set PKN-1A was developed, and neutron irradiation of the container was simulated under conditions of transportation of the neutron source IBN-8-5. The equivalent dose rate (EDR) values on the surface of containers with different composition of the radiation-shield material are calculated. Experimental studies of the EDR attenuation of neutron radiation from isotopic sources of fast neutrons for samples of various radiation-shield material compositions have been carried out. The results of mathematical modeling are in good agreement with experimental data.
