“…The arithmetic mean for radon concentration measurements in soil was 29.3 kBq m -3 . The recorded values, ranging between 0.2 and 179.0 kBq m -3 are comparable to those reported for typical European soil (Beaubien et al, 2003;Al-Khateeb et al, 2017). The geometric mean obtained in the present study was within the range reported at small-scale level in Romania (Cucos et al, 2017.…”

“…Even a stratified analysis which took into account the absence of concrete screed and the type of floor did not provide a statistically significant correlation between residential radon concentration and radon in soil. Other studies, reported by Al-Khateeb et al (2017) fail to reach an agreement whether radon concentration in soil alone would be a sufficient indicator for radon concentration indoor.…”

“…The measurements of the radon concentration in soil, has often been used as an indicator and a predictive method to evaluate the elevated indoor radon concentrations of on area (Akerblom, 1987;Demoury et al, 2013;Cosma et al, 2013;Borgoni et al, 2014;Al-Khateeb et al, 2017;Chen and Ford, 2017;Timkova et al, 2017). The distribution of radon gas in soil can be strongly influenced by local parameters such as chemical and mineralogical composition, physical properties, climatic and geological factors.…”

“…This relationship may not represent causation between the indoor radon concentrations and the concentrations of radon emanated from the soil samples, but it does describe an existing pattern for the study area. Moreover, studies have reported strong correlations between radon concentrations in the indoor air and soil around the building, values of 0.66 [22] and 0.68 [23].…”

Purpose In this study, measurements of radon concentrations and estimation of exhalation rates were carried out in soil around buildings within Lagos State in order to determine the contribution to indoor radon concentrations from the soil, and determine the influence of soil moisture on the exhalation rates. Methods Fifty-four samples were collected randomly with 27 measured as wet samples and 27 dried before measurements so as to account for the moisture content. Passive measurement method, using cover cup technique with solid state nuclear track detectors, CR-39, was employed. Results The results showed weak correlations between the concentrations of radon emanated from the soil samples and the indoor radon concentrations. The results obtained suggested lower concentrations of radon emanated from wet soil than dry soil indicating the influence of moisture. The results further indicate that the highest and lowest values as well as the highest mean for both wet and dry soil samples were obtained from the same environment, suggesting that the soil in that environment are of anomalous petrophysical property. Conclusion Concentrations of radon emanated from dry soil are higher than in wet soil, suggesting that the presence of moisture may results in reduction of radon concentrations in soil samples. The result of the surface exhalation rates and the mass exhalation rates are in congruent with results obtained for the concentrations of radon emanated from wet and dry soil samples.

“…Radon-222 can be found in soil, rocks and water. The main source of indoor radon is radon in soil [3]. The isotopes of radon found in nature ( 222 Rn, 220 Rn, and 219 Rn) are the product of a natural decay series of Uranium ( 238 U), Thorium ( 232 Th) and Actinium ( 235 U), respectively.…”

In this study, the activity concentration of indoor radon-222, annual effective dose, exhalation rate of radon, and relative risk of lung cancer are reported for different indoor buildings (students' dorms, teachers' dorms, offices, laboratories, library, lecture halls, and materials store) in Faculty of Education, Yafea, Aden University, Yemen. Sealed-can technique based on CR-39 nuclear tracks detector was distributed to radon gas survey. Twenty six radon detectors were mounted in seven buildings. The Radon measurements were performed for 90 days between December 2020 and March 2021. The results showed that the radon concentration ranges from 23,18 Bq m-3 to 66.49 Bq m-3 with an average value 35.86 Bq m-3, the annual effective dose ranges from 0.6 mSv y-1 to 1.639 mSv y-1 with an average value 0.979 mSv y-1, the exhalation rate ranges from 10.03 m Bq m-2 h-1 to 28.50 mBq m-2 h-1 with an average value 15.68 mBq m-2 h-1 and relative risk of lung cancer ranges from 1.02 to 1.06 with an average value 1.03. A strong correlation coefficient has been observed between radon concentration and radon exhalation rate. All of the values revealed in the study were of nominal state (that is less than allowed global values) and thus have no risk for the population living in these buildings.
