Relation between natural and anthropogenic factors in the redistribution of radionuclides on the 30 km Chernobyl NPP territory, including the result of countermeasures
[en]Before the accident natural and anthropogenic ecosystems occupied about 90% of 30-km zone area, including 36% of forest ecosystem, ploughed lands -28%, meadows and bogs - 18%. About 10% of total areas were occupied by ameliorated lands, separate water reservoirs - 2.8% relatively large area. Ten years after the Chernobyl accident the lands structure was changed: Areas of forest territories became larger (up to 12-13%). Areas of territories occupied by different technical constructions, roads were increased too. Contamination of different objects of 30-km zone territory is very uneven, for instance variation of 137Cs contamination of soil reaches the same thousand times (From 0.1-5 up to 10000 and more Ci/km2)
