Visualization of dose distribution inside soft X-ray machine based on OSL technology

Abstract

In this study, as a part of the development of the radiation mapping technology, we are planning to develop the gamma-ray imager based on a passive detector such as a dosimeter. For this purpose, we demonstrated the use of nanoDot OSLD as a passive detector being irradiated inside a soft x-ray machine then combined the irradiation position (qualitatively) with radiation dose (quantitatively) for visualization purpose. The experimental results showed that the NanoDots exhibit good linearity and reproducibility when subjected to soft X-rays machine, Hence, the nanoDots showed a promising potential for visualization of dose distribution.
