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 and 10 MV (flat and unflat), 15 MV and 6 and 15 MeV electron beams were found to be linear. Furthermore, these OSLDs exhibited a relative energy‐dependent response for both photon and electron beams. The relative energy response correction factor for photon and electron beams were in the range 1.01–1.05 and 1.03–1.06, respectively.

在治疗性光子和电子束中，本地开发的光学激发发光剂量计Al2 O3：C，LiMgPO4：B和LiCaAlF6：Eu，Y的相对能量响应。

在治疗性光子和电子束中研究了三种以盘状形式固有发展的光学激发发光（OSL）磷光体的相对能量响应。在⁶⁰ Coγ射线，高能X射线和放射治疗中使用的电子束中，在5–500 cGy的剂量范围内对吸收剂量进行了校准。使用这些OSL光盘（OSLD）估算吸收剂量的组合标准不确定度为3.3％。这些OSLD在^60个剂量-反应曲线伽玛射线，6和10 MV（平坦和不平坦），15 MV和6和15 MeV电子束被发现是线性的。此外，这些OSLD对光子和电子束都表现出相对能量依赖的响应。光子束和电子束的相对能量响应校正因子分别在1.01–1.05和1.03–1.06之间。
