摘要：
The state of radioactive pollution of Lake Ladoga has been studied. The purification half-life of lake water from 90Sr was found to be 21.7 year. The ratio of 90Sr storage in lake water volume to its storage in silts (0–10 cm layer) was 2: 1. Lake water purification from global 137Cs was slower than that from 137Cs originating from Chernobyl emergency emission because of the chronic supplement of global 137Cs reserve by atmospheric fallouts. The behavior of 90Sr, 137Cs, and 239,240Pu in bed soils was in agreement with the geochemical nature of the elements. By the distribution of 239, 240Pu in bed soils, the sedimentation of substances of non-radiation nature was estimated at 0.3 and 0.5 mm/year at denting and flat relief, respectively.
