Ovisnost koncentracije radija o morskim strujama u priobalnom moru

The paper deals with the assessment of 226Ra levels in the bay of Northern Adriatic where the quality of seawater and the environment of surrounding coastal area may be endangered by the operation of a coal-fired power plant located close to the seaside. The study was conducted by the Radiation Protection Unit of the Institute for Medical Research and Occupational Health in Zagreb in collaboration with the Institute for Oceanography and Fishery in Split. The aim was to determine vertical and horizontal distribution of radium and its dependence on the seawater currents at different sea depths. The level of 226Ra was assessed in seawater four times a year, at three locations and at two sea depths. According to the results based on the analyses of samples collected at the sea surface and at the depth of 3 m, seasonal variations were not found at any location. Calculated correlations showed high conformity of the values by separate locations and samplings.
