There is a growing interest in protection against localized exposure to radiation in the human body and localized dose measurement at the corresponding points. While this interest is growing, workers are now required to wear multiple devices, such as protective gear and dosimeters, which can hinder their work and burden them. Suppose a wearable device that combines protection and measurement functions can be developed. In that case, it will improve the quality of life of radiation workers and become an essential indicator for technological development in dose optimization. To address this potential technological issue, our research group has developed a prototype of a wearable dosimeter device that incorporates phosphate glass, which exhibits the RPL (radio-photoluminescence) phenomenon, into the glass lens component. In this study, we have developed a prototype of a wearable RPL dosimeter device by attaching the developed dosimeter lens to a commercially available protective eyeglass lens structure while changing the lens thickness by polishing the lens for implementation. In this presentation, we will report on the prototype and the results of preliminary tests using a small reading device.
