Assessment of radioecological situation of a site contaminated by technologically enhanced natural radioactivity in Croatia

The paper deals with radioactivity contamination originating from the coal fired power plant and its waste dumps located in a bay of the Adriatic which is due to geographical characteristics sensitive to any kind of pollution including the radioactivity. Investigations of coal used in regular plant operation and of solid incombustible ash and slag showed increased concentrations of natural radioactivity which may cause general environmental contamination of the bay as well as contamination of the marine environment of this part of Croatian Adriatic. There are two coal slag and ash piles. one of them was closed and covered by soil and the other is still operating pile. The location of both pile present a considerable environmental problem: situated close to the seaside, slag and ash are accumulating in the littoral zone and, in the case of operating pile are being filled up directly into the sea. The aim of this study was to determine radioactivity level at the ash and slag deposit and to assess the risk from increased radioactivity to the inhabitants of the nearby urban area, to the plant workers and general environment of the bay including the marine environment of this part of the Croatian Adriatic.
