Abstract: Neutron shielding properties of poly boron (PB), borax mixed ilmenite-magnetite concrete (BX) and the multilayers PB+BX and their reversed combinations have been studied using a 252Cf point source whose emission characteristics are similar to that of inside a reactor core. For the detection of neutron, a BF3 long counter detector has been used. The shielding characteristics such as transmission factors, removal cross-sections and fluence spectra have been measured. MCNP code has been adopted for the calculations. The multilayered shields are found to show better performance than the single layered ones, thus supporting applicability of it for practical purpose.
