摘要：

There is no authoritative study on marine radioactivity in the Arabian Gulf of Saudi Arabia nor is there any trusty measurements in the Red Sea's side of Saudi Arabia as well. Different surface sediment samples have been collected in three coastal areas from the the Saudi side of the Arabian Gulf.. Those samples were collected at different depths varying from 5 to 25 meters, depending on the surface type and its geological composition, from 11 locations along the gulf coast. Activity concentrations of measured radionuclides K-40, U-238, U-235, Th-230, Ra-226, Th-232, Th-228, and Ra-228 were : 23.69-253.3, 23.11 - 39.76, 1.05 - 1.65, 0.20 - 1.83, 1.99 - 9.46, 0.12 - 0.95, 0.11 - 1.15, 1.25 - 10.26 Bq/Kg respectivelty. All natural radionuclides measurements fall within the international accepted limits.
