Abstract In a wide international cooperation, thin dosimetric films were developed for radiation protection and clinical dosimetry applications. The goal was providing proof of principle of a novel approach to entrance surface dosimetry, in general, and to extremity dosimetry, in particular. The latter is an extremely challenging task since ring and wrist dosimeters do not allow reliable estimates of the higher doses typically received by the fingertips, while solid-state detector chips worn on the fingertips interfere with the tactile sense of the workers. In our current system, tissue-equivalent polyethylene films are used to embed a variety of luminescent materials, particularly radiophotoluminescent (RPL) glass grains. This work illustrates the results we have achieved so far, proving that polyethylene films loaded with RPL glass grains provide a dosimetric response and have adequate mechanical and wearability properties. Additionally, the signal build-up associated with RPL glass is significantly accelerated when the glass is kept at body temperature, i.e., in contact with the worker's hands. Finally, the use of double gloves further improves the performance of our system.

使用放射光致发光薄膜的入射表面剂量测定

摘要 在广泛的国际合作中，开发了用于辐射防护和临床剂量测定应用的剂量测定薄膜。目标是为一般的入口表面剂量测定，特别是肢体剂量测定提供一种新方法的原理证明。后者是一项极具挑战性的任务，因为环形和腕部剂量计无法对指尖通常接收到的较高剂量进行可靠估计，而指尖上佩戴的固态探测器芯片会干扰工作人员的触觉。在我们目前的系统中，组织等效聚乙烯薄膜用于嵌入各种发光材料，特别是放射光致发光 (RPL) 玻璃颗粒。这项工作说明了我们迄今为止取得的成果，证明装有 RPL 玻璃颗粒的聚乙烯薄膜可提供剂量响应，并具有足够的机械和耐磨性能。此外，当玻璃保持在体温下时，即与工人的手接触时，与 RPL 玻璃相关的信号积累会显着加速。最后，使用双手套进一步提高了我们系统的性能。
