Fallout strontium and caesium transfer from vegetation to cow milk at two lowland and two Alpine pastures

Vegetation-to-milk transfer coefficients for Cs-137, Sr-90 and stable strontium were determined For cows grazing on two intensively managed lowland pastures and two Alpine pastures in Austria. The Sr-90 transfer coefficient at the four pastures ranged from 0.0005 to 0.0012 dl(-1) and correlated with the stable strontium transfer coefficient (0.0006 - 0.0013 dl(-1)) with the lower values found on the intensively managed pastures. The Cs-137 transfer coefficient ranged from 0.0009 - 0.0045 dl(-1). (C) 2001 Elsevier Science Ltd. All rights reserved.
