Radon measurements in well and spring water of the Tuzla area, Bosnia and Herzegovina.

Investigations of natural radioactivity in water, air, and soil are conducted frequently and routinely. Exposure to high concentrations of natural radioactive radon gas can cause irradiation of respiratory organs, which can lead to lung cancer. This paper presents measurements of radon activity concentrations in dug wells and natural springs of the Tuzla area (Bosnia and Herzegovina), which ranged from 214 to 3702 mBq L-1. Our results have shown that the radon activity concentration did not exceed the EU reference level for radon in drinking water (100 Bq L-1).
