Full TextAbstract
This study aimed to investigate a shielding design against neutron and photon rays from neutron irra- diators based on Am–Be sources, using the Monte Carlo simulation. Different shielding materials were studied, including borated polyethylene, DaGa concrete, and epoxy resin with colemanite. The Monte Carlo N-particle code (MCNP)was used to design shielding.Anewtype of neutron and photon shielding material based on 40 % galena, 55% polyethylene, and 5 % boric acid is proposed. The results show that the total effective dose of radiation is significantly reduced by the optimum radius of this shielding system.
