Abstract

Current farming practice in upland areas of Cumbria, England, affected by Chernobyl fallout is to remove lambs to lowland pastures for fattening prior to slaughter. The radiocaesium (137Cs and 134Cs) burden of lambs is rapidly lost via excreta deposited on the pasture. This may increase the radiocaesium activities in vegetation of these pastures. Studies were performed to assess the radioecological consequences of this practice. Results obtained from experiments were used to calibrate a soil/vegetation model which was used to predict long-term radiocaesium behavior.

摘要

在英格兰坎布里亚郡受切尔诺贝利核辐射影响的高地地区，目前的养殖做法是在宰杀前将羔羊转移到低地牧场育肥。羔羊体内的放射性铯（137铯和134铯）通过排泄到牧场上而迅速流失。这可能会增加这些牧场植被中的放射性铯活度。开展了多项研究以评估这种做法的放射生态后果。实验所得结果用于校准一个土壤/植被模型，该模型被用来预测放射性铯的长期行为。
