Buildup Factor and Linear Attenuation Coefficient of MCP-69 alloy

MCP-69 alloy was investigated using gamma ray sources ranging from 0.662 MeV to 1.333 MeV for its possible use in radiation shielding and as wedges in radiation treatment planning. Narrow beam geometries were used to determine the linear attenuation coefficient, mass attenuation coefficients and half value layer of the alloy. Linear attenuation confident was also calculated theoretically and numerically using the ideas and concepts of Compton scattering. Broad beam geometry was used to determine the Buildup factor as a function of beam energy, attenuator thickness and geometry of experimental set up.
