ABSTRACT

Areas of anomalous concentrations of natural radionuclides and other toxic elements in
water has been defined by hydro-geochemical regional prospecting in the frame of
nuclear and other mineral resources researches. Geochemical tests were performed in
the tertiary basin of area “Vranjska banja”, in accordance with metallogenetic and
geological-structural and morphological characteristics.
During the regional prospecting, water samples were collected, on the hydrographic
network, from surface streams, springs, wells and drills. Contents of uranium and
parameters such as pH value, Eh, and Ep, were determined in all water samples. In
addition, contents of 238U, 226Ra and 222Rn, microelements, the anion-cation
composition, O2, H2S, CO2 gases, mineralization and hardness, were determined in the
recently collected samples due to radioactive anomalies checking and evaluation.
Increased concentrations of macroelements, especially contents of: Br, I, F, and Zn,
natural radionuclides 238U, 226Ra and 222Rn, were recorded in water samples.
Research results are presented in tables, diagrams and maps. According to
hydrogrochmical test results as well as other geochemical and geophysical
investigations it is possible to define radiological areas with significant impacts of
natural radionuclides in environment of rural South Serbia.
