Description | ||||||
Mass attenuation coefficient, effective atomic cross-section and effective atomic number of CaSO4 and BaSO4 compound samples were determined for the energy 81keV, 356keV, 511keV, 662keV, 1173keV, 1274keV and 1332keV by using gamma ray transmission method. The gamma rays emitted from 22Na, 133Ba, 137Cs and 60Co point sources have been used to be measured gamma rays transmission for the compounds. It is found that the mass attenuation coefficient and atomic cross-section decrease with increasing gamma ray energy. The variations of effective atomic number (Zeff) with photon energy for the compounds were dictated by photon interaction process. |
