The results of dosimetric and radiometric analyses of ionizing radiation emitted by natural radionuclides conducted in the Curonian Spit and other recreational locations nearby water reservoirs in Vilnius, Lithuania, are presented. The research was carried out with mobile measuring instruments, data registration and accumulation equipment, applying Global Positioning System. The distribution of equivalent dose rates in the locations has been measured. Soil samples were taken from the locations where equivalent dose rate was measured and specific activities of major gamma radiators were evaluated using spectrometric analysis. The coefficient correlation was detected between 40K, 226Ra, 232Th and 137Cs specific activities and equivalent dose rates above sample collection location. The coefficient of correlation between 40K and 226Ra specific activity in soil and in bottom mud water is identified.

Przedstawiono wyniki dozymetrycznych i radiometrycznych pomiarów naturalnego promieniowania jonizujacego na terenia Mierzei Kurońskiej. Badania prowadzono, korzystajac z przenośnego urządzenia rejestrującego wyposażonego w system GPS. Stwierdzono korelację między aktywnością promieniotwórczą radionuklidów 40K, 226Ra, 232Th i l37 Cs a równoważną dawką promieniowania jonizującego w miejscach pomiarów. Zaobserwowano również korelację między aktywnością promieniotwórczą radionuklidów 40K i 226 Ra w glebie i osadach dennych.
