摘要

提出了一种结构紧凑、使用方便的局部辐射剂量计，该剂量计采用掺银磷酸盐玻璃晶体透镜，具有射电光致发光（RPL）特性。RPL玻璃镜片集成到眼镜中作为剂量计，覆盖眼睛前面的大片区域，作为视觉确认暴露和定量辐射分析的方便工具。基于集成电路和现场可编程门阵列的专用，方便和紧凑的读出系统也为可穿戴RPL剂量计开发和优化。在x射线或γ射线照射后，可以很容易地确认和评估辐射。此外，发现左右透镜之间的串扰有限，并在早期临床演示中证实了剂量计和读出装置的基本操作，可用于简单的辐射监测和局部辐射暴露的被动剂量监测。

Convenient monitoring of local radiation exposure using an eyewear-type dosimeter and dedicated compact readout system

A compact and convenient local radiation dosimeter is proposed using crystalline lenses composed of Ag-doped phosphate glass, which exhibits radio photoluminescence (RPL). The RPL glass lenses are integrated into an eyewear-glasses as dosimeter that covers a large area in front of the eye and acts as a convenient tool for the visual confirmation of exposure and quantitative radiation profiling. A dedicated, convenient, and compact readout system based on an integrated circuit with a field-programable gate array is also developed and optimized for the wearable RPL dosimeter. Radiation can be easily confirmed and evaluated after X-ray or γ-ray exposure. Moreover, the crosstalk between the left and right lenses is found to be limited, and the basic operation of the dosimeter and readout device, which can be used for simple radiation monitoring and passive dose monitoring of localized radiation exposure, is confirmed in an early clinical demonstration.

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
