“…In order to estimate the radiological impact on the workers due to waterborne 222 Rn inhalation, the mean contribution of the water 222 Rn in the indoor air concentrations was evaluated, based on a transfer coefficient from water to air of 2.7Â10 23 (19,24) . Hence, the 222 Rn concentrations of the spa indoor installations were found to be 2611 Bq m 23 for Apollo, 362 Bq m 23 for Spilaio and 2746 Bq m 23 for Asclepiad. The annual effective dose equivalent due to inhalation was calculated using the conversion 1.5Â10 21 mSv per Bq h m 21 .…”

“…Internal dose rates due to waterborne 222 Rn inhalation. The annual effective dose equivalent due to 222 Rn inhalation was calculated using the factor 1.4Â10 25 mSv per Bq h m 23 , on the assumption of a mean total stay in the indoor place of the installations 45 min for a mean number of 10 therapies. The results are shown in Table 4.…”

A radiological survey has been carried out in the island of Ikaria based on the natural radionuclide inventory in abiotic environment and the consequent dose rate assessment for the critical groups of population. The island of Ikaria-Aegean Sea, Greece is characterised by the presence of mineral and thermo-mineral springs, which have an apparent influence on natural background radiation of the island. The levels of natural radionuclides in spring water (either for spa treatment and household use), potable water (local domestic network), and rock and soil samples were measured in this island. The concentrations of (222)Rn and natural gamma emitters were found to be significantly elevated in spring water and some rock and soil samples. In terms of NORM and TENORM, the external and internal dose rates (mSv y(-1)) were estimated in three groups of population selected on the basis of water use as: habitants of the island, working personnel and bathers in spa installations. According to the derived results, the working personnel in the thermal spa installations are exposed to significant radiological risk due to waterborne (222)Rn with a maximum dose rate up to 35 mSv y(-1), which led to overexposure in terms of the 20 mSv y(-1) professional limits. Therefore, this group can be considered as the critical one for the radiological impact assessment in the island.
