Dynamic of the content of radionuclides in water of cooling-pond of Chernobyl NPP (1978 - 2004)
Dynamic of the artificial radionuclides content of in water of the cooling-pond of ChNPP was studied starting from 1978 till 2004. The total content of radionuclides was founded within the limits of 0,005 - 0,05 Bq/l in the period of 1978 - 1984. After the accident in 1986 the total content of rad...

| Summary: | Dynamic of the artificial radionuclides content of in water of the cooling-pond of ChNPP was studied starting from
1978 till 2004. The total content of radionuclides was founded within the limits of 0,005 - 0,05 Bq/l in the period of
1978 - 1984. After the accident in 1986 the total content of radionuclides in water amounted to 3,7 ⋅ 105
Bq/l. The main
contribution in radionuclides’ pollution of water introduces 137Cs and 90Sr from the end of 1986. Their content is sharply
decreased till 1990 - 1992, and then the decrease occurs more smoothly. Seasonal dynamic of the content of 137Cs is
revealed. In by autumn its quantity in water is increased. The abnormal low relation 90Sr/137Cs in water of cooling-pond
on comparison with other reservoirs 30-km Zone is registered during 1987 - 2004. The content of radionuclides in water
of the cooling-pond of ChNPP in 2004 approximately in 100 times exceeds the levels of content before the accident. |
