Natural radioactivity in the marine environment in CroatiaEnvironment

The production of electrical energy from fossil fuel, among other pollutants, gives rise to the emission of radioactivity. After incineration of coal, the initial radioactivity becomes 7-10 times more concentrated. Consequently, the storage of large quantities of ash and slag may pose significant environmental risk. Investigations of natural radioactivity, particularly radium and uranium have already been performed on selected locations along the Adriatic coast, as a part of an extensive monitoring program of the Croatian environment. This paper deals with the increased levels of natural radioactivity in the bay at the northern part of the Adriatic coast, due to continuous accumulation of slag and ash originated from regular operation of the power plant. In order to assess the risk for the employees in the plant and inhabitants of the area, were performed analyses of the radioactivity levels at the slag and ash deposits as well as dosimetric measurements. In order to assess the sensitivity of the bay to the radioactive pollution, natural radioactivity concentrations were also studied in the zone between the plant and the seaside, as well as in sea water.
