“…The disequilibrium observed between these two radionuclides has already seen in underground waters (Rodenas et al 2008). Our previous study (Yarar et al 2014) focused on indoor radon levels of houses and spas in this area. It has been found that indoor and water radon levels are showning similarities from one location to another location.…”

The radioactivity levels ( 222 Rn and 226 Ra) and physico-chemical properties of geothermal waters from two spas of Bayındır are investigated. Radon and radium measurements were made with collector chamber method. The radon concentrations range from 3.0 to 13.3 Bq/l, whereas the radium varies from 0.35 to 1.71 Bq/l. It has been observed that radon levels increase in winter and decrease in summer. The 222 Rn/ 226 Ra ratio was found to range from 4.91 to 30.53. Physico-chemical properties of water samples were also analysed. Water samples have considerably stable total dissolved solids values, slight acidity, low electrical conductivity, and temperature (42-48°C).

“…Many studies have reported the relationship between indoor radon exposure and lung cancer, and it is estimated that exposure to high radon levels at least 10% of the lung cancer cases in the US. IARC has de ned radon gas as a human carcinogen because its progeny emits radioactive alpha particles capable of causing lung cancer (Bräuner et al 2012;Şen et al 2013;Yarar et al 2014). It is classi ed as the second cause of lung cancer after smoking (Baltrenas et al 2020).…”

Indoor radon concentrations and meteorological parameters were measured in an o ce of the teaching staff at the Institute of Nuclear Sciences, Ege University. Data were collected hourly over 25 months (762 days). Raw data, diurnal, monthly, and seasonal variation of parameters were investigated separately.The results show that the average indoor radon concentration (18 Bq m − 3 ) is relatively lower than national and international reference values. Indoor radon concentrations showed an increasing and decreasing trend throughout the day. Radon concentrations are slightly higher in the morning (downtime and early hours of the day) and then reduced in the afternoon. This can be related to the daily routine usage of the o ce, which is affected by ventilation of the room, air temperature variations, etc. HighlightsIndoor radon concentrations are considerably lower than national and international reference values. Radon concentrations are slightly higher in the early hours of the day and then decrease in the afternoon.Indoor radon concentrations vary wider in autumn and winter than in other seasons (spring and summer).

“…Radon has been studied for a long time [1] because of its harmful health effects (lung cancer) and its concentration variation related to the geodynamic events (earthquakes and volcanic tremors etc.). It is a colorless, odorless, naturally occurring, chemically inert and radioactive gas [2,3]. It is originated from the deep layers of earth crust and moves to the atmosphere by diffusion and convection or advection [4,5,6].…”

Radon which occurs in uranium decay series is a noble gas and it moves from the deeper layers of the earth crust to the atmosphere. Formation of the radon gas in the Earth's crust and its migration to the atmosphere are quite a complex process due to the external factors like tectonic movements, meteorological factors etc. In this process, both the advection and diffusion are effective mechanisms for radon transport. But, the most effective mechanism is diffusion. In this study, radon diffusion of soils taken from Küçük Menderes Basin was investigated by controlled laboratory experiments and the radon diffusion coefficient of these soils was calculated. Soil gas radon measurements were performed by LR 115 Type 2 solid state nuclear track detectors.
