In this work, a passive detection technique is utilized to analyze radon, ²²²Rn, concentration levels in indoor and outdoor air after implanting 126 (CR-39) detectors for 130 days during the winter season in Irbid governorate, the second largest governorate in Jordan. Also, the spatial variations of the outdoor ²²²Rn concentrations in the air were interpolated and mapped using ArcGIS. Kriging method has been found the finest, among other geostatistical methods, for generating outdoor ²²²Rn concentration spatial interpolations with the least uncertainty and highest smoothness. The outdoor radon concentrations have ranged from 9 to 72 Bq m^-3, while the indoors' have started as low as 17 and up to 102 Bq m^-3. There was no clear realizable correlation among the identified indoor and outdoor air radon concentration levels. However, the calculated health risk indicators associated with radon inhalation show that around 11 residents in every 1000 could have an increased risk of lung cancer developing due to relatively higher radon gas exposure levels. These findings are important when applying radon policies both at the local and at the national levels, in terms of changing the air ventilation practices and for identifying areas of priority for further study, zoning, and land-use decision.

在这项工作中，在约旦第二大省伊尔比德省冬季植入 126 (CR-39) 探测器 130 天后，利用被动检测技术分析室内和室外空气中氡、²²² Rn 的浓度水平. 此外，使用 ArcGIS对室外空气中²²² Rn 浓度的空间变化进行了插值和映射。克里金法被认为是在其他地质统计学方法中最好的，用于生成具有最小不确定性和最高平滑度的室外²²² Rn 浓度空间插值。室外氡浓度从 9 到 72 Bq m ^-3不等，而室内则从低至 17 到 102 Bq m ^-3. 确定的室内和室外空气氡浓度水平之间没有明确的可实现的相关性。然而，与氡吸入相关的计算出的健康风险指标表明，由于氡气暴露水平相对较高，每 1000 名居民中约有 11 人患肺癌的风险可能增加。在地方和国家层面应用氡政策时，这些发现对于改变空气通风实践和确定进一步研究、分区和土地使用决策的优先领域非常重要。
