“…Radon levels in the environment can show important spatial variations on a regional or local scale. It has been recognized that this lateral variability is primarily attributed to geological parameters which control the radon source-term and/ or the radon migration in the ground (Appleton et al, 2015;Bossew, 2015;Drolet et al, 2013Drolet et al, , 2014García-Talavera et al, 2013;Gruber et al, 2013;Hahna et al, 2015;Ielsch et al, 2001Ielsch et al, , 2002Ielsch et al, , 2010Kropat et al, 2014;Scheib et al, 2013;Smethurst et al, 2008;Tondeur et al, 2015;Zhukovsky et al, 2012). Therefore, the knowledge of uranium and/or radium contents in rocks is of primary importance to determine the radon source term.…”

“…However, detailed geochemical studies demonstrated levels of up to 4.5 ppm for certain geological formations within the Witwatersrand Supergroup [42,43]. Studies revealed that rocks with uranium content of about 2 ppm hold great potential to results in significant radon contributions [44,45]. These observations ascertain that the rocks of the Witwatersrand Supergroup solely make significant radon contributions of about 34 Bq/m 3 in the outdoor environment, which can, therefore, be characterised as the baseline value for areas with a similar geological makeup.…”

Radon gas has long been identified as a human carcinogen. The purpose of this study was to understand the occurrence of radon gas in the West Rand region, located west of the city of Johannesburg, South Africa, and to investigate its potential health effects. In this study, the sampling of rocks, tailings, and construction materials was carried out for geochemical analyses. For characterisation of radon, 60 radon monitors (RGMs) were installed in indoor and outdoor environments. The results showed that mine tailings contain high uranium levels, with a maximum of 149.76 ppm and a mean value of 48.87 ppm. The radon levels in the area ranged between 32 Bq/m3 and 1069 Bq/m3 and thus, exceed the typical outdoor radon levels of about 10 Bq/m3. Significantly high values were obtained from gold tailings dams. In indoor environments, radon concentration ranged up to a maximum of 174 Bq/m3, which is above the recommended value of 100 Bq/m3. The effective doses calculated from the obtained radon levels showed a maximum of 16 mSv/y, which is above the recommended value of 1 mSv/y proposed for public exposure. The estimated doses have an enormous potential to pose high lung cancer risks to the populations residing nearby tailings.

“…Approaches to radon hazard assessment have included direct measurements of indoor radon (Dubois, 2005), soil gas measurements (Kemski et al, 2001;Dubois, 2005;Barnet, 2011;Cinelli et al, 2015), chemical analysis of bedrock and soils (Ielsch et al, 2010;Drolet et al, 2013), and airborne eU (equivalent uranium) measurements (Åkerblom, 1995;Ford et al, 2001;IAEA, 2003;Smethurst et al, 2008;Drolet et al, 2013). Many studies have investigated relationships between geology and indoor radon (e.g.…”
