已经提出了一些评估框架，以提供一种机制来证明保护环境免受电离辐射的影响。虽然其中一些被用于评估目的，但它们在很大程度上没有根据实地测量进行验证。在这篇文章中，我们将其中一个框架(FASSET)推荐的转移参数的预测与切尔诺贝利禁区内一系列哺乳动物和无脊椎动物物种的观察到的~(90)Sr和放射性铯活度浓度进行了比较。预测的活性浓度一般在观测范围内，对参考生物体的平均预测与观测平均值相似，或大约比观测平均值高一个数量级。然而，一些预测比观测值低了一个数量级以上。没有数据可以用来测试切尔诺贝利事故发布的其他放射性核素的预测。在另一篇论文中，这项评估的结果将用于估计参考生物体的剂量，并将其与切尔诺贝利地区报告的观测到的辐射引起的影响进行比较。
A number of assessment frameworks have been proposed to provide a mechanism to demonstrate protection of the environment from ionising radiation. Whilst some of these are being used for assessment purposes they have largely not been validated against field measurements. In this paper we compare the predictions of transfer parameters recommended by one of these frameworks (FASSET) with observed whole-body 90Sr and radiocaesium activity concentrations in a range of mammal and invertebrate species sampled within the Chernobyl exclusion zone. Predicted activity concentrations were generally within the observed ranges and mean predictions for reference organisms were similar to, or circa one order of magnitude higher than, the observed means. However, some predictions were more than one order of magnitude lower than observed values. No data were available to test predictions for the other radionuclides released by the Chernobyl accident. In a separate paper the outputs of this assessment will be used to estimate doses to reference organisms and compare these to observed radiation induced effects reported within the Chernobyl zone.
