Abstract

Sediments collected from the Techa River at Nadirov Bridge were analysed for Tc-99. The maximum concentration was found at a depth of 14-18cm. This layer was sedimented around 1950, i.e. at a time when the maximum releases of waterborne radionuclides occurred to the river from the MAYAK plutonium production plant in the Urals. The vertical distribution of Tc-99 in sediments followed that of Cs-137, and the mean ratio between Tc-99 and Cs-137 in the sediments at the time of discharge was 0.41 x 10(-3). Laboratory experiments showed that Tc-99 under anoxic conditions, e.g. when organic material is decomposing, will be retained br sediments. (C) 1997 Elsevier Science Ltd.
