Abstract |
|
|
| Shielding effectiveness of six hydrogenous materials (polymer and plastic) for gamma and fast neutron are investigated using total mass attenuation coefficients, mass energy absorption coefficients, KERMA, effective atomic number, electron density and macroscopic effective removal cross-sections. The program WinXCOM for photons and mass removal cross section for individual elements for neutrons were used. It is found that increase of H-atom concentration leads to improve the neutron shielding and reduce gamma shielding effectiveness. Also, difference in effective mass removal cross-sections for elements using the theoretical computation and experiment was observed. Present investigation should be useful for application of these materials used in shielding in various nuclear facilities. |
