The RESRAD-BIOTA Level 1 default Biota Concentration Guides (BCGs) are generic screening environmental medium concentrations based on reasonably conservative concentration ratios (CRs). These CRs had been identified from available literature for a variety of biota organisms. The International Atomic Energy Agency (IAEA) Technical Report Series (TRS) handbook on radionuclide transfer to wildlife was recently published with data that can be compared with the RESRAD-BIOTA values. In addition, previous IAEA Environmental Modeling for Radiation Safety (EMRAS) II Biota Working Group model comparison results are examined by comparing them with those obtained using the new TRS CR values for wildlife. Since the CR affects only internal doses, the effect on the overall dose depends on the relative contribution from internal and external exposure pathways.
RESRAD-BIOTA 水平 1 默认生物群集浓度指南 (BCGs) 是基于合理保守浓度比 (CR) 的通用筛选环境介质浓度。这些 CR 是从各种生物群生物体的现有文献中确定的。国际原子能机构 (IAEA) 最近出版了一本关于放射性核素向野生动物转移的技术报告系列 (TRS) 手册，其中包含了可与 RESRAD-BIOTA 值进行比较的数据。此外，通过将新的 TRS CR 值与野生动物的新 TRS CR 值进行比较，还检查了先前的 IAEA 环境辐射安全建模 (EMRAS) II 生物群工作组模型比较结果。由于 CR 仅影响内部剂量，因此对总剂量的影响取决于内部和外部暴露途径的相对贡献。
