摘要: Abstract The gamma radiation shielding capability (GRSC) of two clay-materials (Ball clay and Kaolin)of Southwestern Nigeria (7.49°N, 4.55°E) have been investigated by determine theoretically experimentally the mass attenuation coefficient, μ/ρ (cm2g−1) materials at photon energies 609.31, 1120.29, 1173.20, 1238.11, 1332.50 1764.49 keV emitted from 214Bi ore 60Co point source. coefficients were evaluated using elemental compositions obtained Particle-Induced X-ray Emission (PIXE) analysis technique as input data for WinXCom software. While ray transmission experiment Hyper Pure Germanium (HPGe) spectrometer detector to coefficients, samples. experimental results are in good agreement with theoretical calculations Linear coefficient (μ), half value layer (HVL) mean free path (MFP) also values GRSC selected compared other studied materials. cognizance various factors such availability, thermo-chemical stability water retaining ability clay-samples can be analyzed efficacy material their GRSC.
