The thermoluminescent dosimetry is currently applied to radiation therapy in order to measure dose distributions on phantoms or to control the dose in vivo for special procedures or critical organs. The application of this method to the SIN's (Switzerland) pion beam has been studied. Measurements have been made on the following thermoluminescent materials: 7LiF, 6LiF, Li(nat)F, Li2B4O7, CaF2 : Mn, and CaF2 : Dy. Except for the last one a reduction (10%) of the sensitivity of the phosphors has been observed in the peak relative to the plateau region. An increase of the 6LiF sensitivity relative to that of 7LiF has been pointed out due to the neutron background through the (n, alpha) reaction on 6Li. Glow curves of the LiF phosphors have been measured. A reduction (5%) of the intensities of peak 3 and 4 relative to peak 5 has been observed for irradiation in the peak region. This effect however can't be used in order to localize the dosimeter in the beam because the intensity of the thermoluminescence peaks shows a larger variability in a batch of dosimeters.
热释光剂量测定法目前应用于放射治疗，用于测量体模上的剂量分布或在特殊程序或关键器官中控制体内剂量。已研究了该方法在瑞士保罗谢尔研究所（SIN）的π介子束中的应用。对以下热释光材料进行了测量：7LiF、6LiF、天然锂（Li(nat)）F、Li2B4O7、CaF2:Mn和CaF2:Dy。除了最后一种材料外，观察到相对于坪区，磷光体峰值处的灵敏度降低了10%。由于6Li上的（n，α）反应产生的中子本底，指出6LiF相对于7LiF的灵敏度有所增加。已测量了LiF磷光体的发光曲线。在峰值区域照射时，观察到相对于峰值5，峰值3和4的强度降低了5%。然而，由于热释光峰值的强度在一批剂量计中显示出较大的变化性，这种效应不能用于在束中定位剂量计。
