[Accumulation of 90Sr in field crops in conditions of radioactive pollution of agricultural lands].
In the field experiment the influence of manure, peat, lake silt and their combinations on the uptake of 90Sr by barley, corn and potatoes was studied. Saturation of soil with organic substance, the decrease in soil acidity resulted in the lower accumulation of 90Sr by plants. In the beginning of the experiment, the specific activity of barley grain was from 75 to 132 Bq/kg. After three years of application of fertilizers the content of 90Sr in the barley grain decreased to 39 Bq/kg. There were no increase in 90Sr accumulation by the basic field crops with time.
