The radiological assessment of non-human biota to demonstrate protection is now accepted by a number of international and national bodies. Therefore, it is necessary to develop a scientific basis to assess and evaluate exposure of biota to ionizing radiation. Radionuclides from the Ignalina Nuclear Power Plant (Lithuania) were discharged into Lake Druksiai cooling pond. Additional radionuclide migration and recharge to this lake from a hypothetical near-surface, low-level radioactive waste disposal, to be situated 1.5 km from the lake, had been simulated using RESRAD-OFFSITE code. This paper uses ERICA Integrated Approach with associated tools and databases to compare the radiological dose to freshwater reference organisms. Based on these data, it can be concluded that background dose rates to non-human biota in Lake Druksiai far exceed those attributable to anthropogenic radionuclides. With respect the fishery and corresponding annual committed effective human dose as a result of this fish consumption Lake Druksiai continues to be a high-productivity water body with intensive angling and possible commercial fishing.
许多国际和国家机构现在都接受了将非人类生物群的放射学评估作为证明保护的手段。因此，有必要制定科学依据来评估和评估生物群对电离辐射的暴露。立陶宛伊格纳利纳核电站的放射性核素被排放到德鲁斯基艾冷却池。假设在距离湖泊 1.5 公里的地方存在一个近地表、低水平放射性废物处置场，使用 RESRAD-OFFSITE 代码模拟了这些放射性核素从该处置场向该湖的迁移和补给。本文使用 ERICA 综合方法及其相关工具和数据库来比较淡水参考生物的放射性剂量。根据这些数据，可以得出结论，德鲁斯基艾湖中非人类生物群的背景剂量率远远超过归因于人为放射性核素的剂量率。鉴于渔业以及由于食用这些鱼类而导致的相应年度人类有效剂量，德鲁斯基艾湖仍然是一个具有高强度垂钓和可能商业捕鱼活动的高生产力水体。
