<br/><br/> The aim of this work was to investigate surface doses of 6 and 10 MV photons for different clinical setup parameters including field size, gantry angle, source surface distance, physical wedge, perspex block tray and tissue equivalent wax block. Comparison between measured surface dose by parallel plate ion chanmber (PPIC), and that measured by thermo luminescence dosimeter (TLD) and that calculated by treatment planning system (TPS) was done
