Abstract
The results of measurements of radon and thoron concentrations in soil gas and in
waters as well as radon exhalation rate, gamma dose rate and sampling soil for gamma
spectroscopy measurements are reported. Extremely high radon (222Rn) concentrations were observed in soil gas (> 2000 kBq/m3) in Niška Banja town. Very high values of radon exhalation rates (1,5 Bq/m2s) as well as radon concentration in water samples (> 500 Bq/l) were also found. The next control measurements and monitoring of radon risk are planned for full recognition and understanding of that unusual phenomenon. A survey on chosen areas in Serbia and Montenegro was done in June 2004. The first area (Niška Banja Spa) is located in the South-Eastern Serbia. The other one is Obrenovac, near Belgrade. This field work was organized and headed by dr Zora S. Zunic from ECE Laboratory (VINCA Institute of Nuclear Sciences, Belgrade).
