The rapid rise in the application of novel treatment techniques, such as intensity-modulated radiotherapy (IMRT), motivated us to survey the status of Korea's radiation safety management and the shielding designs of facilities employing medical linear accelerators (LINACs). To this end, a questionnaire was used to collect information on LINAC facilities and treatments, workload, shielding design, shielding management, and path of obtaining shielding information. Out of 100 domestic institutions, 52 responded to the survey. Approximately 70% of the institutions utilized IMRT for more than 60% of their cases, and an IMRT factor of 5 was adopted by 75% of these institutions. Over 80% of the institutions accounted for the applied time-averaged dose rate per week and instantaneous dose equivalent rates in their shielding designs. Approximately 45% of the institutions obtained important shielding information via a radiation shielding design company and the NCRP-151 report. Overall, most facilities were shown to follow the standards recommended by the relevant international agencies. However, the requirement to establish standardized shielding design information and clarify ambiguous paths for information acquisition was also highlighted. Therefore, the study's results can be used as a foundation for establishing a safety control system and for creating adequate shielding designs.

调强放射治疗 (IMRT) 等新型治疗技术的应用迅速增加，促使我们调查韩国的辐射安全管理状况以及采用医用直线加速器 (LINAC) 的设施的屏蔽设计。为此，使用问卷收集有关 LINAC 设施和治疗、工作量、屏蔽设计、屏蔽管理和获取屏蔽信息的路径的信息。在100家国内机构中，有52家回复了调查。大约 70% 的机构在 60% 以上的案例中使用了 IMRT，其中 75% 的机构采用了 IMRT 系数 5。超过 80% 的机构在其屏蔽设计中考虑了每周应用的时间平均剂量率和瞬时剂量当量率。大约 45% 的机构通过辐射屏蔽设计公司和 NCRP-151 报告获得了重要的屏蔽信息。总体而言，大多数设施都遵循相关国际机构推荐的标准。但是，也强调了建立标准化屏蔽设计信息和澄清信息获取的模糊路径的要求。因此，该研究的结果可以作为建立安全控制系统和创建适当屏蔽设计的基础。还强调了建立标准化屏蔽设计信息和澄清信息获取的模糊路径的要求。因此，该研究的结果可以作为建立安全控制系统和创建适当屏蔽设计的基础。还强调了建立标准化屏蔽设计信息和澄清信息获取的模糊路径的要求。因此，该研究的结果可以作为建立安全控制系统和创建适当屏蔽设计的基础。
