A set of data on the equilibrium concentration factors of 90Sr in fish in relation to the Ca concentrations in water was collected and analyzed. An empiric relationship was obtained on the basis of statistical processing of this dataset: CF(90Sr, Bq/kg w.w.) = 3940(1770-6110)/[Ca, mg/L]water. The range of observed data on the concentration factors of 90Sr in fish is from 20 to 4000 L/kg (about 200 times). The statistical relationship obtained in the paper allows one to reduce this uncertainty by more than 50 times. The formula adequately describes equilibrium concentration factors of 90Sr both in freshwater and in marine fish. A dynamics model approach is described for the cases of accidental contamination of water bodies, when the equilibrium approaches are not appropriate.
收集并分析了一组关于鱼类中90Sr平衡浓度因子与水中Ca浓度关系的数据。基于该数据集的统计处理得到了一个经验关系：CF(90Sr, Bq/kg湿重)=3940(1770 - 6110)/[Ca, mg/L]水。鱼类中90Sr浓度因子的观测数据范围为20至4000 L/kg（约200倍）。本文得到的统计关系可使这种不确定性降低50倍以上。该公式充分描述了淡水鱼和海鱼中90Sr的平衡浓度因子。还描述了一种动力学模型方法，用于水体意外污染的情况，此时平衡方法并不适用。
