开发了一种基于 LiF 单晶和挤出颗粒的放射光致发光 (RPL) 的剂量测定方法。 LiF 热释光剂量测定 (TLD) 由于其组织等效响应及其物理特性，目前已应用于临床。例如TLD 的缺点是：a）它在几百 R 开始的剂量水平上饱和；b）读出过程具有破坏性。在许多临床应用中，需要能够在更高剂量下工作的剂量计。基于 Regulla 和 Claffy 等人的工作。开发了一种使用 LiF 的 RPL 方法，该方法可以在更高剂量下使用并保持组织等效响应。
A dosimetric method based on the radiophotoluminescence (RPL) of single crystals and extruded pellets of LiF has been developed. Thermoluminescence dosimetry (TLD) with LiF is currently used in clinical applications because of its tissue equivalency response and its physieal characteristics; e.g. small size, non-sensitivity to humidity, flexibility in geometrical form, etc. Disadvantages of TLD are: a) it saturates at a dose level beginning at several hundred R and b) the readout process is destructive. In many clinical applications a dosimeter is needed that can operate at higher doses. On the basis of the work of Regulla and Claffy et al. an RPL method using LiF was developed which can be used at higher doses and maintains tissue equivalency response.
