Özet

The macroscopic cross-section I pound and average neutron fluence in matter I broken vertical bar are usable factors to comment neutron shielding property of samples. In this paper, we have used MgB2, NaBH4 and KBH4 samples including different percentages of boron. Neutron macroscopic cross-section measurements of them have been done by using a source of mono-energetic neutrons (E (eff) = 4.5 MeV Am-241-Be). Average neutron fluence values and double differential fast neutron flux distributions of each samples calculated by using FLUKA Monte Carlo code. Also half value layers (HVLs) of samples are compared to paraffin which is one of the most neutron moderators. As a result, growing boron concentration can raise neutron shielding property of materials.
