Abstract
In the field of radiation medicine, particularly within radiotherapy applications, radiochromic chemical dosimeters are indispensable tools for dose measurement. This study focuses on the novel development of a radiochromic dosimeter tailored for the precise detection of low-dose radiation, aiming to construct a dosimeter with tissue-equivalent properties suitable for accurately measuring low to medium radiation doses. Utilizing ferrous xylenol orange gel (FXG), we developed two tissue-equivalent dosimeter formulations based on gelatin and polyvinyl alcohol (PVA). Our findings demonstrate that the gelatin-based FXG dosimeter exhibits a robust linear dose-response relationship, facilitating precise dose measurements in the range of 50 to 5000 mGy. Conversely, the PVA-based FXG dosimeter proved effective for dose measurements within a narrower range of 600 to 5000 mGy. Notably, the gelatin-based dosimeter's performance underscores its potential as a versatile tool in radiation detection, promising significant benefits for both medical and industrial applications. This research confirms the efficacy of the Fricke dosimeter gel, demonstrating its linear response across a dose range of 0.05 to 5 Gy, thus establishing a foundation for further advancements in accurate and reliable low-dose radiation monitoring.
