Assessment of Radioactivity in Groundwater and Silt from some Underground Wells in Southern Sinai, Egypt

This study investigated the radioactivity of groundwater and bottom silt from wells in southern Sinai, Egypt. Eight well sites were chosen (Abu Redis, Abu Zenima, and Al-Tor) and composite samples of water and silt were created from each. Southern Sinai well water (Egypt) was safe for drinking based on tested elements (²²⁶Ra < 300 Bq/L, ²³²Th < 100 Bq/L). However, some bottom silt samples showed elevated ²²⁶Ra, ²³²Th, and ²²²Rn-, potentially posing health risks through inhalation or ingestion. Further investigation is needed on these specific silt samples due to potential internal and external radiation exposure.
