Development of a system for on-site dosimetry audit of high-dose-rate brachytherapy
Despite international standards, the lack of an independent audit system in South Korea has led to quality management challenges in high-dose-rate brachytherapy, prompting the development of a precise source activity measurement system and a regulatory MATLAB code. We developed an audit system that integrates a source strength measurement system and mechanical accuracy check phantoms using a well-type chamber electrometer setup and an in-house MATLAB code. We achieved audit suitability with appropriate uncertainty and compatibility across various Remote After-Loading System (RALS). Our uncertainty assessments revealed the proposed expanded uncertainties (k = 2) of 2.72% and 2.71% for models 70010 and 72280, respectively. Based on these results, we plan to implement this auditing system nationwide to comply with domestic regulations.
期刊介绍：
The Journal of the Korean Physical Society (JKPS) covers all fields of physics spanning from statistical physics and condensed matter physics to particle physics. The manuscript to be published in JKPS is required to hold the originality, significance, and recent completeness. The journal is composed of Full paper, Letters, and Brief sections. In addition, featured articles with outstanding results are selected by the Editorial board and introduced in the online version. For emphasis on aspect of international journal, several world-distinguished researchers join the Editorial board. High quality of papers may be express-published when it is recommended or requested.
