Monitoring of radioactive contamination of water systems after Chernobyl accident
- V.G. Khlopin Radium Inst., St. Petersburg (Russian Federation). Dept. of Radioecological Monitoring and Waste Management
The contamination of the water systems within the Russian North-West region, the Danube river and the reservoir of the Dnieper River during the period from June 1986 to 1992 was studied. The water reservoirs in the vicinity of the Chernobyl NPP contained suspended matter and the bottom sediments contained a wide range of radionuclides, including the isotopes of Pu and TPE. In the Baltic Sea and the allied river and lake reservoirs the concentrations of {sup 137}Cs ({sup 134}Cs was also detected) increased drastically, however, the concentrations of {sup 90}Sr and plutonium isotopes remained essentially at the global level. The Danube River contained increased concentrations of {sup 137}Cs and {sup 90}Sr as compared with 1985; no rise in the concentration of plutonium was observed. In subsequent years (1987--1990) the concentration of cesium isotopes in the reservoirs decreased sharply; but, on the other hand, their concentrations in sediments increased.
