Relative energy response of indigenously developed optically stimulated luminescence dosimeters Al2O3:C, LiMgPO4:B and LiCaAlF6:Eu,Y in therapeutic photon and electron beams
Abstract:The relative energy responses of three indigenously developed optically stimulated luminescence (OSL) phosphors in the disc form were studied in therapeutic photon and electron beams. Calibration in terms of absorbed dose was carried out in the dose range 5–500 cGy in 60Co gamma rays, high energy X‐rays, and electron beams used in radiotherapy. The combined standard uncertainty in the estimation of absorbed dose using these OSL discs (OSLDs) was 3.3%. Dose–response curves of these OSLDs in 60Co gamma rays, 6 a… Show more
