“…There are different regional studies on radon exposure during thermal applications. (Vogiannis et al 2004;Walczak et al 2015;Műllerová et al 2016;Yıldız et al 2018) In the current study, radon activity concentrations in groundwater and geothermal water have been measured in some parts of Büyük Menderes Graben where active fault lines are spread over a wide area. In addition, indoor radon concentrations were measured during thermal treatments and effective doses were calculated.…”

Radon gas is the widest and primary origin of radiation exposure due to natural radiation sources. Radon and its short-term decay products may adhere to small particles in the air and inhalation of these particles cause an increase in lung cancer risk by irradiating lung tissues by alpha radiation. Radon can reach living spaces by diffusion in air or dissolving in water and also it is well known that radon readily soluble in water and the solubility of radon increases quickly while the temperature of the water is decreasing. For this reason, investigation of radon activity concentration levels in drinking water, groundwater and geothermal waters is necessary to avoid exposure to radiation due to water use. In this study, dissolved radon concentrations in geothermal water samples and the indoor radon levels during the treatment in thermal bath facilities, were measured by using AlphaGUARD PQ2000Pro. The indoor measurements were performed at three facilities which contain bathrooms using geothermal waters in September 2019. Radon levels in the geothermal waters of the region were determined by collecting water samples from nine locations in the geothermal fields in the Büyük Menderes Graben. The annual effective doses received by residents and visitors due to indoor radon concentrations between 753-186 Bq/m 3 was calculated.

“…A large number of studies have been conducted on indoor radon concentrations in thermal spas, e.g. in the Middle-Slovakian region, Lądek-Zdr oj in south-western Poland, the thermal spas of Rudas and H evíz in Hungary, J achymov in the Czech Republic, etc (Szerbin et al, 1994;Lu civjanský;Durecov a, 2000;Domb ov ary et al, 2006;Jobb agy et al, 2010;Nowak et al, 2012;Z€ olzer et al, 2013;Walczak et al, 2016). Nikolov et al (2012) studied radon levels at the spa in Ni ska Banja, Serbia and measured activity concentrations indoors and in water in thermal pools and therapy rooms.…”

It has been proven that more than half of the exposure to natural background radiation originates from radon isotopes and their decay products. The inhalation of radon and its decay products causes the irradiation of respiratory tracts, thus increasing the risk of lung cancer. In this study, the concentrations of radon and thoron in thermal baths at a spa in Dehloran (Iran) were investigated. The concentrations of dissolved 226 Ra in samples of water from thermal baths were also measured. Additionally, the activity concentrations of abundant naturally occurring radionuclides in farmland soils irrigated with water from hot springs was measured and compared with other soil samples irrigated with water from other sources to estimate possible radioecological effects of natural radiation staff, patients and tourists at the spa are exposed to. In addition, the search for a link between the concentration of naturally occurring radionuclides in soil and the use of water from hot springs for irrigation was one of the main goals of the study. The activity concentrations of three major naturally occurring radionuclides in soil samples were measured; the ranges for 40 K, 226 Ra and 228 Ra were 101 AE 8 to 240 AE 12, 276 AE 7 to 322 AE 12 and 20 AE 7 to 80 AE 10 Bq.kg À1 , respectively. Higher activity concentrations of 226 Ra and 228 Ra were recorded in soil samples irrigated with hot spring water. The water from the same spring was used in all thermal baths so concentrations of dissolved 226 Ra in water samples from different thermal baths were approximated to also be 0.42 AE 0.20 Bq.l À1 . The indoor radon concentrations in the private thermal baths over a period of 45 days (including both occupied and vacant time) were measured to be between 1880 AE 410 and 2450 AE 530 Bq.m À3 and the radon concentrations in the spa galleries were measured to be between 790 AE 135 and 1050 AE 120 Bq.m À3 , however, thoron concentrations were below the detection limit. The ventilation and centralized heating systems at the spa under investigation are inefficient so the radon concentrations in the therapy rooms and baths are high.The maximum radiation doses originating from the inhalation of radon for tourists and the staff were estimated to be 0.13 and 5.5 mSv.yr À1 , respectively, which is slightly over the national limit in Iran (5 mSv.yr À1 ). The exposure duration was estimated 15 and 1468 h per year for visitors and workers, respectively.

“…Se observan cantidades de radón en interiores por encima del límite legislativo pese a que, en algunos casos, la cantidad de radón en agua no supera los valores paramétricos fijados para aguas de consumo humano (Nikolov et. al, 2012;Walczak et al, 2016;Kulali,2021). A nivel nacional, algunos estudios llevados a cabo en Tenerife se centran en realizar medidas de radón en aire durante periodos de 3 meses en el interior de galerías de agua con el objetivo de cuantificar cuanto gas es exhalado desde la fuente acuática.…”
