The transfer of Cs137 from grass and silage to milk has been followed in detail for one farm in West Cumbria over the year following the deposition from the Chernobyl reactor accident. At this farm about 40% of the Cs137 in milk was attributed to the feeding of silage during the following winter. A wider study of an additional 14 farms showed considerable variations in the contributions from grazing and silage. The transfer quotient from silage to milk was comparable with the values measured for grass over the first few weeks and lower than values reached later in the grazing season.
在切尔诺贝利反应堆事故发生后的一年里，西坎布里亚郡的一个农场对铯 - 137从青草和青贮饲料转移到牛奶中的情况进行了详细跟踪。在这个农场，来年冬季牛奶中约40%的铯 - 137来自青贮饲料喂养。对另外14个农场进行的更广泛研究表明，放牧和青贮饲料的贡献存在很大差异。青贮饲料到牛奶的转移系数在前几周与青草测量值相当，低于放牧季节后期达到的值。
