Abstract
This work studied the percent depth doses of 60Co photon beams in the buildup region of a plastic phantom by LiF TLD measurements and by Monte Carlo calculations. An agreement within ± 1.5% was found between PDDs measured by TLD and calculated by the Monte Carlo method with the TLD in a plastic phantom. The dose in the plastic phantom was scored in voxels with thickness scaled by physical and electron density. PDDs calculated by electron density scaling showed a better match with PDD(MC, TLD) ; the difference is within ± 1.5% in the buildup region for square and rectangular field sizes.
