Deposition of radionuclides from the Chernobyl nuclear reactor in the Ukraine occurred over much of the United Kingdom. The magnitude of the deposition varied considerably, depending on the prevailing weather, but even in areas of low deposition, iodine-131, caesium-134 and caesium-137 were measurable on pasture and in cows' milk. The accident provided an opportunity to study the influence of differences in herd management and in climate upon transfer to cows' milk. In this paper, results from a small mixed farm in Cumbria are compared with those from a large dairy farm in Berkshire for the first few weeks after deposition. The contrasting herd management practices in operation at these farms result in very different temporal variations in activity concentrations in milk, although in neither case were the maximum concentrations in milk sufficient to warrant restrictions on distribution or consumption.
乌克兰切尔诺贝利核反应堆的放射性核素沉降在英国大部分地区。沉降量差异很大，这取决于当时的天气，但即使在沉降量低的地区，牧场和牛奶中也能检测到碘-131、铯-134和铯-137。这次事故提供了一个研究畜群管理和气候差异对牛奶转移影响的机会。本文将坎布里亚郡一个小型混合农场在沉降后头几周的结果与伯克郡一个大型奶牛场的结果进行了比较。尽管两个农场牛奶中放射性活度浓度的最大含量都不足以限制牛奶的销售或消费，但这两个农场不同的畜群管理方式导致了牛奶中放射性活度浓度随时间的变化差异很大。
