Radiophotoluminescence Phenomenon of CaF₂ Ceramics Doped with Li

Photonics, 2023
The objective of this study is to examine the impact of Li-doping on the radiophotoluminescent (RPL) properties of CaF2. Before ionizing irradiation, Li-doped CaF2 exhibited no photoluminescence (PL) under excitation in the range of 250–700 nm.

In vivo dose measurement using TLDs and MOSFET dosimeters for cardiac radiosurgery. [PDF]

, 2012
In vivo measurements were made of the dose delivered to animal models in an effort to develop a method for treating cardiac arrhythmia using radiation. This treatment would replace RF energy (currently used to create cardiac scar) with ionizing radiation.

New real-time patient radiation dosimeter for use in radiofrequency catheter ablation

Journal of Radiation Research, 2019
In a previous study, we reported on a novel (prototype) real-time patient dosimeter with non-toxic phosphor sensors. In this study, we developed new types of sensors that were smaller than in the previous prototype, and clarified the clinical feasibility
