In this study, nearly 84 marine sediment samples were collected from twelve points in four cities (Quseir, Safaga, Hurghada, and Ras Gharib) along the Egyptian Red Sea sectors. The collected samples were extensively examined to estimate the natural radioactivity level. The obtained results were compared to the reported ranges from other locations in different countries. Hazardous radiation parameters such as radium equivalent, annual dose, and external hazards were estimated and compared to United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) recommended levels. The values were recorded in the first natural radioactivity database of coastal sediments from Egyptian Red Sea cities. The dose rate for certain organs was evaluated. The results showed that Red Sea beach sediments are safe in terms of natural radioactivity. It can be concluded that they do not pose a risk to tourists going to the beaches for recreation or to sailors and fishers involved in economic activities along the Egyptian Red Sea coast.

在这项研究中，从埃及红海沿岸的四个城市（库赛尔、萨法加、赫尔格达和拉斯加里布）的 12 个点收集了近 84 个海洋沉积物样本。对收集的样本进行了广泛检查，以估计天然放射性水平。将获得的结果与来自不同国家其他地点的报告范围进行了比较。估算了诸如镭当量、年剂量和外部危害等有害辐射参数，并与联合国原子辐射影响科学委员会 (UNSCEAR) 推荐的水平进行了比较。这些值记录在埃及红海城市沿海沉积物的第一个天然放射性数据库中。评估了某些器官的剂量率。结果表明，就天然放射性而言，红海海滩沉积物是安全的。
