dc.description.abstractThe objective of this study is to assess the natural resources and radiological risks of Wadi El Gemal Island by examining its topography, mineralogy, geochemistry, and radioactive distributions. This island, which is situated at the outlet of Wadi El Gemal in Egypt's southeastern Desert, has a unique shape resembling a dolphin based on Landsat imagery. It's a part of the Wadi El Gemal-Hamata Protectorate and is notable for its diverse environmental, geological, economic, and archeological features, including recent reefs, sandy deposits, Quaternary carbonate sediments, and mangroves. The main natural resources on the island are fauna, mangrove forests, and flora. Samples collected from the island were analyzed using a NaI detector to measure the concentrations of radionuclides such as 238U, 232Th, 226Ra, and 40K, which were found to be within acceptable levels according to UNSCAR guidelines. The radionuclide 238U, 232Th, 226Ra, and 40K activity concentrations of the collected samples were 32.55 & PLUSMN; 9, 12.63 & PLUSMN; 4, 12.49 & PLUSMN; 4, and 325 & PLUSMN; 34 Bq/kg, respectively. Regarding radiological hazard indices, the values of absorbed gamma dose rate (36.06 & PLUSMN; 5.42 nGy/h), radium equivalent activity (73.88 & PLUSMN; 14.4 Bq/kg), annual effective dose indoor (0.18 & PLUSMN; 0.03 mSv/y) and outdoor (0.04 & PLUSMN; 0.01 mSv/y), internal (0.29 & PLUSMN; 0.05) and external (0.2 & PLUSMN; 0.03) indices, and excess lifetime cancer index (0.15 & PLUSMN; 0.05 x 10-3).This is suggest that there is no significant risk associated with these sediments.en_US
