Under the International Atomic Energy Agency (IAEA)'s EMRAS (Environmental Modelling for Radiation Safety) programme, activity concentrations of (60)Co, (90)Sr, (137)Cs and (3)H in Perch Lake at Atomic Energy of Canada Limited's Chalk River Laboratories site were predicted, in freshwater primary producers, invertebrates, fishes, herpetofauna and mammals using eleven modelling approaches. Comparison of predicted radionuclide concentrations in the different species types with measured values highlighted a number of areas where additional work and understanding is required to improve the predictions of radionuclide transfer. For some species, the differences could be explained by ecological factors such as trophic level or the influence of stable analogues. Model predictions were relatively poor for mammalian species and herpetofauna compared with measured values, partly due to a lack of relevant data. In addition, concentration ratios are sometimes under-predicted when derived from experiments performed under controlled laboratory conditions representative of conditions in other water bodies.
在国际原子能机构(IAEA)的环境辐射安全建模(EMRAS)计划下,运用11种建模方法预测了加拿大原子能有限公司乔克河实验室场址鲈鱼湖的淡水初级生产者、无脊椎动物、鱼类、两栖爬行动物和哺乳动物体内的(60)钴、(90)锶、(137)铯和(3)氢的活度浓度。将不同物种类型中预测的放射性核素浓度与测量值进行比较,突出显示了一些需要开展更多工作和加深理解以改进放射性核素转移预测的领域。对于某些物种,差异可由营养级或稳定类似物的影响等生态因素来解释。与测量值相比,哺乳动物物种和两栖爬行动物的模型预测相对较差,部分原因是缺乏相关数据。此外,当根据在代表其他水体条件的受控实验室条件下进行的实验得出浓度比时,有时会预测不足。
