We studied the concentrations of terrestrial and anthropogenic radionuclides in seawater and shore sediment/sand of three selected regions; Khafji, Safaniyah and Menifah along the Saudi Arabian Gulf coast. The mean activity concentrations of the ²²⁸Ra, ²²⁶Ra, and ⁴⁰K in the analyzed sand samples are 5.9, 3.5 and 113.5 Bq/kg, and the respective values in seawater samples are 1.6, 0.8 and 10.4 Bq/L. All data show lower than the corresponding UNSCEAR (2000) reported world average values of 35, 30 and 400 Bq/kg for soil matrix. A few relevant radiological hazards were quantified by the estimation of the absorbed dose rate, and the results are compared with the prescribed limits set by international regulatory bodies. Measured data indicates that the studied coastal regions pose a negligible radiological hazards to the public, and show an insignificant radioactive loading to this coastal region by the Busher nuclear power plant.

我们研究了三个选定区域的海水和海岸沉积物/沙子中的陆地和人为放射性核素浓度；沙特阿拉伯海湾沿岸的海夫吉、萨法尼亚和梅尼法。²²⁸ Ra、²²⁶ Ra 和⁴⁰的平均活度浓度分析的沙样中的K分别为5.9、3.5和113.5 Bq/kg，海水样品中的K分别为1.6、0.8和10.4 Bq/L。所有数据均显示低于相应的 UNSCEAR（2000 年）报告的土壤基质 35、30 和 400 Bq/kg 的世界平均值。通过估计吸收剂量率对一些相关的放射性危害进行了量化，并将结果与​​国际监管机构规定的限值进行了比较。测量数据表明，所研究的沿海地区对公众构成的放射性危害可以忽略不计，并且显示布舍核电站对该沿海地区的放射性负荷微不足道。
