Resumen:
Mass attenuation coefficients, effective atomic numbers, effective electron
densities for nuclear materials; thorium, uranium and plutonium compounds
have been studied. The photon attenuation properties for the compounds have
been investigated for partial photon interaction processes by photoelectric effect,
Compton scattering and pair production. The values of these parameters have
been found to change with photon energy and interaction process. The variations
of mass attenuation coefficients, effective atomic number and electron density
with energy are shown graphically. Moreover, results have shown that these
compounds are better shielding and suggesting smaller dimensions. The study
would be useful for applications of these materials for gamma ray shielding
requirement.
