摘要

氡是一种五官无法检测到的致癌气体，对居住在全球所有封闭建筑物中的人的健康构成严重威胁，尤其是肺癌。本研究的目的是：(1) 测量土耳其伊兹密尔 117 栋建筑物的室内氡浓度 (IRC)；(2) 研究 IRC 与地质单元 (GU) 和活动断层 (AF) 之间的关系并建立模型；(3) 将 IRC 值与欧洲室内氡参考水平 (EIRRL) (200 Bq/m³)进行比较，以确定因室内氡浓度 (IRL) 升高而对肺癌健康构成潜在风险的区域。在 117 栋建筑物中使用固态核跟踪探测器 (SSNTD) 对室内氡浓度进行了测量。这些测量在 2013 年 2 月至 2013 年 3 月期间进行。将 IRC 与 GUs 和 AFs 一并显示在地图上，并根据该地图上的数据生成地质横截面图。117 栋建筑物的 IRC 与 AF 一起进行了地质统计建模。一般来说，最高 IRC 位于接近 AF 的位置，平行于 AF 方向的 IRL 有所增加。最高 IRC（487 Bq/m³）出现在一栋位于主要由火山岩形成的冲积层上的建筑物中，而最低浓度（28 Bq/m³）则出现在一栋位于主要由沉积岩形成的冲积层上的建筑物中。确定了 IRC 的统计参数（最小值：28 Bq/m³，最大值：487 Bq/m³，算术平均值：210 Bq/m³）。在伊兹密尔，117 座建筑中有 59 座（约占抽样建筑的 50%）的 IRC 超过了建议的 200 Bq/m³ EIRRL。当务之急是由相关部门定期对所有封闭式建筑物的 IRC 进行定期监测，并在 IRL 超过 200 Bq/m³ 临界值的地方实施缓解措施。

Geological and geostatistical modeling of indoor radon concentration in buildings of İzmir Province (Western Turkey)

Radon is a carcinogenic gas that cannot be detected by the five senses and poses a significant health threat, particularly in the form of lung cancer, to individuals living in all enclosed buildings worldwide.

The aims of this study are to (1) measure Indoor Radon Concentrations (IRCs) in 117 buildings in İzmir, Turkey, (2) investigate and model the relationship between the IRCs and Geological Units (GUs) and Active Faults (AFs), and (3) compare the IRC values with the European Indoor Radon Reference Level (EIRRL) (200 Bq/m³) to identify areas that pose a potential health risk for lung cancer due to elevated Indoor Radon Levels (IRLs).

The IRCs were measured using Solid State Nuclear Track Detectors (SSNTDs) in 117 buildings. These measurements were conducted between February 2013 and March 2013. The IRCs were visualized on a map along with the GUs and AFs, and a geological cross-section was generated from the data represented on this map.

The IRCs in 117 buildings were geostatistically modeled in conjunction with AFs. Generally, the highest IRCs were found in locations proximal to AFs, with an increase in IRLs observed parallel to the AFs's directions. The highest IRC (487 Bq/m³) was recorded in a building located on alluvium derived primarily from volcanic rocks, whereas the lowest concentration (28 Bq/m³) was observed in a building situated on alluvium predominantly derived from sedimentary rocks. The statistical parameters (minimum: 28 Bq/m³, maximum: 487 Bq/m³, arithmetic mean: 210 Bq/m³) of the IRCs were established.

In İzmir, IRCs in 59 out of 117 buildings, representing approximately 50% of the sampled structures, were found to exceed the recommended EIRRL of 200 Bq/m³. It is imperative that IRCs in all enclosed buildings be regularly and periodically monitored by relevant authorities, and mitigation measures should be implemented in locations where IRLs exceed the threshold value of 200 Bq/m³.

期刊介绍： The Journal of Environmental Radioactivity provides a coherent international forum for publication of original research or review papers on any aspect of the occurrence of radioactivity in natural systems. Relevant subject areas range from applications of environmental radionuclides as mechanistic or timescale tracers of natural processes to assessments of the radioecological or radiological effects of ambient radioactivity. Papers deal with naturally occurring nuclides or with those created and released by man through nuclear weapons manufacture and testing, energy production, fuel-cycle technology, etc. Reports on radioactivity in the oceans, sediments, rivers, lakes, groundwaters, soils, atmosphere and all divisions of the biosphere are welcomed, but these should not simply be of a monitoring nature unless the data are particularly innovative.
