“…Thermal springs are generally privileged places of radon emanation (King et al 1996;Jalili-Majareshin et al 2012). It was recognized that high concentrations of radon in water may pose a serious health threat Groundwater samples were collected, in December 2013, from 19 different locations (thermal baths and deep wells).…”

“…Its concentration in groundwater varies because of variable concentrations of sources in the aquifer materials, emanation rates from mineral sources, aquifer porosity, and permeability. It constitutes the major part of the radioactive gases present in mineral and groundwater (Nikolopoulos et al 2009;Jalili-Majareshin et al 2012).…”

“…Previous studies have indicated that 222 Rn concentration in groundwater was due to passing through rocks and sediments of different compositions, mineral waters contain different salts of radium and thorium, which are subsequently decayed to radon (Kendall and McDonnell 1998;Wu et al 2003). However, because of the short half-life of thoron, radon constitutes the major part of the radioactive gases present in mineral and groundwater (Jalili-Majareshin et al 2012). Gurler et al (2010) indicate that the radon concentration in Bursa in Turkey was due to mixed water in some baths from outside sources with very low radon concentration.…”

Hydrogeological and hydrochemical investigations were applied to explain geothermal groundwater flow factors controlling groundwater mineralization, and 222 Rn concentrations were controlled using RAD7-H 2 O in El Hamma aquifer system, southeastern Tunisia. Nineteen geothermal water samples were collected from different locations (thermal baths and deep wells). Physical parameters (EC, pH, TDS, T) were measured, and major ions were analyzed. Hydrogeochemical modeling and thermal parameters reveal that groundwater from El Hamma aquifer system has several origins. The first type was characterized by a hot temperature >55°C with a chemical facies Na-Mg-Ca-SO 4 -Cl . This type characterizes lower cretaceous deep water (continental intercalary aquifer). The second water type was dominated by Na-Ca-Cl-SO 4 facies with a temperature <45°C and represents the superficial aquifer. However, Ca-SO 4 -Na-Cl-Mg is the third water type which is characterized by mixed water from deep and shallow water with a temperature ranging from 45 to 55°C. Shallow aquifer displays higher 222 Rn concentration (677 to 2903 Bq/ m 3 ). However, deep water from continental intercalary displays relatively a low radon concentration (203 to 1100 Bq/ m 3 ). Compared to Rn-222 activity in some countries, radon concentration in El Hamma thermal aquifer system has a medium value controlled by structures, porosity, and permeability of aquifers. Variographic analysis and ordinary kriging techniques were used to map temperature spatial variability in the study area. Geostatiscal techniques in addition to geological data and radon activities confirm the existence of vertical communication between continental intercalary aquifer and superficial Senonian aquifer through vertical faults system.

“…There are many methods and instruments for measuring radon concentration continuously, such as those employing scintillation cells (Hosoda et al 2011), ionization chambers (Swakoń et al 2004;Vogiannis and Nikolopoulos 2008) and electrostatic collectors (Jalili-Majareshin et al 2012;Tan and Xiao 2013;Ruckerbauer and Winkler 2001;Pugliese et al 2000;Tan et al 2015b). Radon monitoring based on electrostatic collection involves an electrostatic collection cell with a silicon surface barrier detector mounted inside the cell.…”

The detection efficiency of electrostatic collection radon monitors is influenced by the humidity of the air in the collection cell. This is due to the recombination of positively charged 218 Po with OH -ions, whose concentration depends on humidity. A novel design of an electrostatic collection cell, in which the air pressure in the cell is less than the atmospheric pressure, is proposed to eliminate the impact of humidity. As a result of the lower air pressure, the drift velocity of the positively charged 218 Po in the electric field increases, so the collection time decreases. A model predicting the collection efficiency of positively charged 218 Po in this kind of electrostatic collection cell is presented. Based on the model, if the air pressure in the cell is sufficiently low, the collection efficiency will be approximately a constant and the dependency of the collection efficiency of the positively charged 218 Po upon the water vapor concentration can be ignored. This approach can be applied to develop a new radon monitor.
