Egypt is currently considering building a nuclear power plant (NPP). Consequently, an environmental impact assessment is required for potential releases to the environment. The aim of this work is to implement an environmental impact assessment for a nuclear power plant to assess radiation doses to man and the wildlife, to aid the decision-making related to the environment effects of that facility. This study focused on atmospheric dispersion modeling code cap88-Pc, ERICA Tool version 1.2 and R&D128 approach for predicting the activity concentrations of released radionuclides and the corresponding dose rates to human, as well as terrestrial and marine wildlife at different distances from the reactor at normal operation. The results of total dose rate to marine wildlife, recommended that the release point to be beyond 1600 m offshore for such organisms to be protected and the summing risk quotient to be well below unity. The risk quotients for terrestrial organisms from deposited radionuclides on the ground and the emitted noble gases were well below unity. The total effective dose rate to man from air emissions and from consumption of contaminated marine species (fish and crustaceans) from liquid discharges combined was 5.19E−3 mSv y⁻¹ corresponding to 2.6E−7 cancer risk factor, which is acceptably low risk. The radionuclide Co-60 was one of the major contributors of dose rate to marine organisms (beside Co-58 and Mn-54) and of total effective dose for human together with Ag-110m and C-14. The current study considered to provide the baseline information for further implementation of regulatory policies when site specific data is available.

埃及目前正在考虑建造一座核电站。因此，需要对可能的环境排放进行环境影响评估。这项工作的目的是对核电厂进行环境影响评估，以评估对人类和野生生物的辐射剂量，以帮助做出与该设施的环境影响有关的决策。这项研究的重点是大气扩散建模代码cap88-Pc，ERICA Tool版本1.2和R＆D128方法，用于预测在正常情况下离反应堆不同距离处对人类以及陆地和海洋野生动植物释放的放射性核素的活性浓度和相应的剂量率操作。海洋野生动物总剂量率的结果，建议对此类生物进行保护的离岸点应在离岸1600 m以上，且总风险商应远低于1。地面上沉积的放射性核素和所散发的稀有气体对陆地生物的风险商远低于统一。空气排放和液体排放相结合所消耗的受污染海洋物种（鱼类和甲壳类）的消费对人的总有效剂量率为5.19E-3 mSv y^-1对应于2.6E-7癌症危险因素，这是可接受的低风险。放射性核素Co-60是海洋生物（Co-58和Mn-54除外）剂量率的主要贡献者之一，是人类与Ag-110m和C-14一起使用的总有效剂量之一。当前的研究认为，当可获得特定地点的数据时，可为进一步实施监管政策提供基准信息。
