The paper provides findings of field studies on parameters of 90Sr transfer in cow’s milk after a single and prolonged radionuclide intake into black cattle with water and meadow vegetation. Cattle were kept in conditions of radioactive contamination at “Degelen” site. A reduction was revealed in the concentrations of 90Sr in cow’s milk after we stopped feeding and watering contaminated food and water. After a single uptake of 90Sr with water in the cattle body the bulk of 90Sr in milk is observed from 12 to 22 hours, when with hay – from 18 hours to 60 hours. The maximal transfer factors in the chain of «water-milk» and «vegetation-milk» were 2.3×10-3 and 4.3×10-4. Transfer factors of 90Sr in cow’s milk after prolonged uptake with water and vegetation are 2.6×10-4 and 2.0×10-4, respectively. 24 hours after long term watering of the cattle with contaminated water 90Sr activity in milk decreased 5 times, after a long feeding with contaminated vegetation 90Sr activity in milk decreased 2 times. 20 days after feeding contaminated grass 0.0013% of 90Sr daily intake is excreted with milk per 1 liter of milk.
