本研究的目的是提供基本数据的评价和管理的健康影响方面，在韩国的住宅环境内接触氡。这是一项病例对照研究的一部分，目的是根据室内氡暴露水平制定一项管理计划，并评估其对健康的影响。为了调查氡的长期累积浓度水平，在韩国招募了599名患有呼吸道疾病的患者，并在2015年年中至2016年末的3个月内在他们的住所安装了α轨道探测器。然后进行调查，以确定影响氡浓度的因素。结合调查结果对氡浓度水平进行了分析。结果表明，住宅氡浓度的算术平均值在70.8 +/-65.2Bq/m3之间。协方差分析（ANCOVA）进行识别的环境因素影响的氡浓度和贡献的住宅氡浓度的高度的基础上的变化。结果表明，当地环境因素对氡浓度变化的贡献（p < 0.05）大于其他环境因素。虽然在控制前建筑物的建造年份方面没有发现统计学上的显著差异（p > 0.05），但在控制后的建造年份方面也发现了同样的显著差异（p < 0.05）。
The purpose of this study is to provide basic data for the evaluation and management of health effects with respect to exposure to radon within residential environments in South Korea. It is part of a case-control study to develop a management plan based on indoor radon exposure levels and assess their impact on health. To investigate the long-term cumulative concentration levels of radon, 599 patients who have respiratory diseases were recruited in South Korea, and alpha track detectors were installed in their residences for a period of 3 months from mid-2015 to late 2016. A survey was then conducted to determine the factors affecting the radon concentration. The radon concentration levels were analyzed in conjunction with the survey results. The results show that the arithmetic mean of the radon concentrations in domestic residences was in the range of 70.8 +/- 65.2 Bq/m(3). An analysis of covariance (ANCOVA) was performed to identify the environmental factors affecting the radon concentration and contributing to variations in the residential radon concentration based on the height of the residence. The results show that the contribution of the local environmental factor to the variation in radon concentration (p < 0.05) was greater than that of other environmental factors. Although no statistically significant difference was found with regard to the construction year of the building before the control (p > 0.05), the same was found with regard to the construction year after the control (p < 0.05).
