Experimental determination of the effective point of measurement in electron beams using a commercial scintillation detector

Purpose null A commercial plastic scintillation detector was used to determine the effective point of measurement (EPOM) of three cylindrical ionization chambers in four clinical electron beams. The experimentally determined EPOM values were compared to Monte Carlo (MC)-calculated EPOM values from the literature. The energy dependence of the EPOM was also investigated. null null null Methods null Percent depth dose (PDD) curves were measured...
