各种热释光磷光体作为热释光剂量计(TLD)早已在辐射剂量学领域里应用。因为 LiF 磷光体是一种接近组织等效的材料,并且对酸、碱、有机深溶剂和水蒸气来说,化学稳定性好,所以 LiF 磷光体对辐射剂量学而言,是最重要的和最有用的磷光体。近来,人们对象10~-粒德(10~(-6)戈瑞)那样的低量测量和环境剂量学领域中更低的剂量测量感兴趣。目前,Mg_2SiO_4(Tb)、CaSO_4(Tm、CaSO_4(Dy)和 CaE_2(Dy)作为高灵敏度的磷光体在应用,但是这些磷光体都有一个较高的有效原子数。
Various thermoluminescent phosphors have long been used in the field of radiation dosimetry as thermoluminescent dosimeters (TLDs). Because LiF phosphors are a material that is nearly tissue-equivalent and chemically stable to acids, bases, organic deep-solvent and water vapor, LiF phosphors are the most important for radiation dosimetry and The most useful phosphor. Recently, people have been interested in low-dose measurements such as Granules (10 -6 (6) Gray) and lower dose measurement in the field of environmental dosimetry. At present, Mg 2 SiO 4, CaSO 4 (Tm, CaSO 4 (Dy) and CaE 2 (Dy) are used as high-sensitivity phosphors, but these phosphors have a higher effective atomic number.
