Fast neutron shielding parameters, such as total macroscopic cross section effect, mean free path and transmission number have been calculated by using Monte Carlo Simulation Geant4 code. Neutron absorbed dose experiments have been carried out by using 4.5 MeV energy 241 Am-Be fast neutron source and BF 3 gas neutron detector. The obtained results have been compared with paraffin and conventional concrete, to determine the radiation shielding capacity of new brick samples. Some interaction parameters for gamma radiation, such as the mass attenuation coefficient and half-value layer (HVL) have been calculated by using WinXCom software, the results have been compared with conventional and basalt heavy concrete. It is found that, the new type brick samples show good shielding capacity for both neutron and gamma radiation. These new type brick samples can use has been determined for shielding material, in nuclear medicine, in the storage of radioactive waste and nuclear power plants. }, number={1}, publisher={Gumushane University}
