摘要

为了评估终生暴露于氡对健康的影响，本研究采用蒙特卡洛模拟法，根据特定年龄的时间活动模式，考虑了各种室内微环境暴露，评估了年有效剂量（AED）和终生累积超额癌症风险（ELCR-C）。据观察，大韩民国各地的室内氡浓度存在显著的地区差异，其中学校和独立式住宅的氡浓度最高。根据每年在室内和室外活动 8760 小时的标准，AED 因年龄组和住宅类型而异，独立式住宅的 ELCR-C 平均约为公寓的 1.36 倍。本研究强调了全面健康风险评估的重要性，这种评估应考虑室内环境和年龄组的差异，这表明对特定地点或区域的有限评估可能会扭曲实际暴露水平。

Assessing the Radon Exposure Variability and Lifetime Health Effects across Indoor Microenvironments and Sub-Populations

To assess the health impacts of radon exposure over a lifetime, in the present study, the annual effective dose (AED) and cumulative excess lifetime cancer risk (ELCR-C) were evaluated by considering various indoor microenvironmental exposures based on age-specific time–activity patterns using Monte Carlo simulations. Significant regional variations in indoor radon concentrations across the Republic of Korea were observed, with the highest levels found in schools and single detached houses. Based on the standard annual total of 8760 h spent indoors and outdoors, the AED varied by age group and dwelling type, with the ELCR-C for single detached houses being approximately 1.36 times higher than that for apartments on average. The present study highlights the importance of comprehensive health risk assessments that consider differences across indoor environments and age groups, indicating that limited evaluations of specific sites or areas may distort actual exposure levels.
