Abstract

Vegetation-to-milk transfer coefficients for 137Cs, 90Sr and stable strontium were determined for cows grazing on two intensively managed lowland pastures and two Alpine pastures in Austria. The 90Sr 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 137Cs transfer coefficient ranged from 0.0009-0.0045 dl-1.

摘要

在奥地利，对在两个集约化管理的低地牧场和两个高山牧场上放牧的奶牛，测定了¹³⁷Cs、⁹⁰Sr和稳定锶的植被-牛奶转移系数。四个牧场的⁹⁰Sr转移系数在0.0005至0.0012 dl⁻¹之间，并且与稳定锶转移系数（0.0006 - 0.0013 dl⁻¹）相关，在集约化管理的牧场上发现的值较低。¹³⁷Cs转移系数在0.0009 - 0.0045 dl⁻¹之间。
