Transfer functions of MCP-200 alloy were determined for beam intensity modulation. 6 MV Photon beam, obtained from linear accelerator, is attenuated by blocks of MCP-200 alloy with different thicknesses placed at a distance of one meter from the source. The attenuated beam was allowed to fall on photographic film and optical densities were measured. Films were scanned and profiles were obtained for different thicknesses of the alloy and in the absence of any attenuator. Transfer functions were obtained theoretically as well as analytically by fitting the experimental results into theoretical data. The whole work was completed using optimum dose units and found to be 30 cGy.
