所有人类都暴露在氡中,天然辐射的主要来源,这可能是由于自然过程而不是人类活动而伤害人。因此,确定室内氡的水平非常重要,土壤气体,水,和户外。在Kiraz地区测量了氡浓度(CRn),伊兹密尔,研究了室内和土壤气体CRn值之间的相关性。在基拉兹的40所随机选择的住宅中测量的室内CRn值表现出从19.50±2.50到204.70±8.00Bqm-3的广泛范围,平均值为61.11±4.23Bqm-3。将测得的室内CRn值与世界上的参考水平进行比较,以帮助控制住宅中的氡。在所有研究的住宅中,室内CRn值均低于ICRP参考水平300Bqm-3。此外,在34所住宅中(占所研究住宅总数的85%),室内CRn值低于WHO参考水平100Bqm-3。健康危害指数,即年度有效剂量(AED)和终生癌症风险(ELCR),还对每个住宅进行了计算,并与国际上可接受的水平进行了比较,以估计对人类健康的风险。AED值从0.49±0.06到5.16±0.20mSvy-1不等,平均值为1.54±0.11mSvy-1,超过UNSCEAR报告的世界平均水平1.15mSvy-1。ELCR值范围为2.05±0.26×10-3至21.55±0.84×10-3,平均值为6.43±0.44×10-3,超过UNSCEAR报告的世界平均水平0.29×10-3。测得的土壤气体CRn值表现出从129.25±6.38Bqm-3到6172.64±44.06Bqm-3的广泛变化,平均值为1291.79±18.70Bqm-3。土壤气体CRn值小于10,000Bqm-3;因此,根据瑞典标准,研究区域被归类为“低氡风险区域”,因此,在研究区域不需要特殊的建筑。当土壤气体CRn值与室内CRn值比较时,CRn值之间未发现线性关系。然而,在室内和土壤气体CRn值分别小于200Bqm-3和2500Bqm-3之间发现了很强的正线性相关。
All humans are exposed to radon, the primary source of natural radiation, which can harm people due to natural processes rather than human activity. Thus, it is of significant importance to determine the levels of radon in indoor, soil gas, water, and outdoors. Radon concentration (CRn) was measured in Kiraz district, İzmir, and the correlation between the indoor and soil gas CRn values was investigated. The indoor CRn values measured in 40 randomly selected dwellings in Kiraz exhibited a wide range from 19.50 ± 2.50 to 204.70 ± 8.00 Bq m-3 with an average value of 61.11 ± 4.23 Bq m-3. The measured indoor CRn values were compared to the reference levels in the world to help control radon in the dwellings. Indoor CRn values were lower than the ICRP reference level of 300 Bq m-3 in all of the dwellings studied. Furthermore, in 34 dwellings (representing 85% of the total number of dwellings studied), indoor CRn values were lower than the WHO reference level of 100 Bq m-3. Health hazard indices, namely annual effective dose (AED) and excess lifetime cancer risk (ELCR), were also calculated for each dwelling and compared with internationally acceptable levels to estimate the risk to human health. The AED values varied from 0.49 ± 0.06 to 5.16 ± 0.20 mSv y-1 with an average value of 1.54 ± 0.11 mSv y-1, which exceeds the world average of 1.15 mSv y-1 as reported by UNSCEAR. The ELCR values ranged from 2.05 ± 0.26 × 10-3 to 21.55 ± 0.84 × 10-3 with an average value of 6.43 ± 0.44 × 10-3, exceeding the world average of 0.29 × 10-3 as reported by UNSCEAR. The soil gas CRn values measured exhibited a wide variation ranging from 129.25 ± 6.38 Bq m-3 to 6172.64 ± 44.06 Bq m-3 with an average value of 1291.79 ± 18.70 Bq m-3. The soil gas CRn values were less than 10,000 Bq m-3; hence, the research area is categorized as \"low radon risk areas\" according to Sweden Criteria, and so no special constructions are required in the studied area. When soil gas CRn values were compared to indoor CRn values, no linear relationship was found between the CRn values. However, a strong positive linear correlation was found between indoor and soil gas CRn values less than 200 Bq m-3 and 2500 Bq m-3, respectively.
