Abstract In optically stimulated luminescent dosimeters (OSLD), the intensity of luminescent is a function of the dose of radiation absorbed and then it may be utilized as the basis of a radiation dosimetry method. For photons in the energy range from 1 keV to 20 MeV, the Kerma coefficients for fifteen OSLD, air, and ICRU standard tissue were calculated respectively from the analytical method and Monte Carlo simulation (MCNPX code). The results of MCNPX are consistent within estimated uncertainties with values evaluated by analytical method. The Kerma ratios of the OSLD relative to tissue were also obtained. The BeO has the closer Kerma to the tissue and alkaline OSL materials have relatively more values so that in 50 keV these ratios reach about 100.

通过分析和蒙特卡罗方法评估 OSL 剂量计的 Kerma 系数

摘要 在光受激发光剂量计 (OSLD) 中，发光强度是吸收辐射剂量的函数，可作为辐射剂量测定方法的基础。对于能量范围从 1 keV 到 20 MeV 的光子，15 个 OSLD、空气和 ICRU 标准组织的 Kerma 系数分别通过分析方法和蒙特卡罗模拟（MCNPX 代码）计算得出。MCNPX 的结果在估计的不确定性内与分析方法评估的值一致。还获得了 OSLD 相对于组织的 Kerma 比。BeO 的 Kerma 与组织更接近，碱性 OSL 材料具有相对更大的值，因此在 50 keV 时，这些比率达到约 100。
