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.
