This study identified occupational factors associated with radiation exposure in Korea. Survey data of 16 037 workers from 2016 to 2017, including lifestyle factors and occupational characteristics, were combined with the National Dose Registry. Higher average annual doses were observed in groups exhibiting health risk factors such as body mass index (BMI) and smoking. Average annual doses also differed according to occupational characteristics, including average daily working hours, use of radiation protection gear, calendar year of hiring and employment status. Moreover, the influence of different factors on radiation dose differed with occupations. In industrial radiography and nuclear power plants, average daily working hours were the most important factor determining worker radiation doses. In other occupations, such as education, industry and research, calendar year of hiring and duration of employment were the most important factors. This research indicates the need to consider the specific work procedures of occupations to determine exposure variations between or within facilities.

韩国放射工作者的职业暴露特征和与放射剂量相关的因素。

这项研究确定了与韩国辐射暴露相关的职业因素。将2016年至2017年16 037名工人的调查数据，包括生活方式因素和职业特征，与国家剂量登记处相结合。在表现出身体质量指数 (BMI) 和吸烟等健康风险因素的群体中观察到更高的平均年剂量。平均年剂量也因职业特征而异，包括平均每日工作时间、辐射防护装备的使用、雇用日历年和就业状况。此外，不同因素对辐射剂量的影响因职业而异。在工业射线照相和核电站中，平均每日工作时间是决定工人辐射剂量的最重要因素。在其他职业，例如教育，工业和研究、雇用日历年和雇用期限是最重要的因素。这项研究表明需要考虑职业的具体工作程序，以确定设施之间或设施内的暴露变化。
