Radiat Prot Dosimetry. 2014 Oct;161(1-4):112-5. doi: 10.1093/rpd/nct217. Epub 2013 Sep 13.
Thermoluminescence (TL) and optically stimulated luminescence (OSL) are the well-known phenomena used for passive methods of dose measurements. TL and OSL detectors are frequently used in the dosimetry of cosmic radiation in space and of particle radiotherapy beams. However, the relative TL/OSL efficiency, which is defined as a ratio of the emitted light intensity per unit dose for a given radiation type, to the same quantity for the reference gamma radiation is not constant and depends on radiation type and energy. In the present work several types of TL and OSL dosimetric materials, including lithium fluoride (LiF), aluminium oxide, beryllium oxide and lithium aluminate, were tested with protons. The measurements were realised exploiting the 60-MeV proton beam of the AIC-144 cyclotron in the Proton Eye Radiotherapy Facility at Institute of Nuclear Physics (IFJ PAN). The influence of proton energy on the relative efficiency and other TL/OSL characteristics of the studied detector types was presented.
热释光（TL）和光激发光（OSL）是用于剂量测量被动方法的著名现象。TL和OSL探测器常用于空间宇宙辐射和粒子放射治疗束的剂量测定。然而，相对TL/OSL效率（定义为给定辐射类型下每单位剂量发射光强度与参考伽马辐射的相同量之比）并非恒定不变，而是取决于辐射类型和能量。在本工作中，几种类型的TL和OSL剂量测定材料，包括氟化锂（LiF）、氧化铝、氧化铍和铝酸锂，用质子进行了测试。测量是利用核物理研究所（IFJ PAN）质子眼部放射治疗设施中AIC - 144回旋加速器的60 MeV质子束进行的。给出了质子能量对所研究探测器类型的相对效率和其他TL/OSL特性的影响。
