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.
