Concentrations of natural radionuclides 226Ra, 232Th and 40K as well as the radiological hazard parameters were calculated in the marine sediments in three regions in Quseir city along the Red Sea coast; El-Edua area, Phosphate Harbour and north Flaminko Village. The average activity concentrations of 226Ra, 232Th and 40K at El-Edua area were, 24.9±3, 19.6±2.4 and 234.5±43 Bq.kg-1 and at Quseir Harbour recorded the average activities concentrations were; 26.2±3.2, 19.4±2.8 and 458.6±164.2 Bq.kg-1 while at north Flaminko Village found to be; 25.7±6.9, 22.6±5 and 106.4±17.5 Bq.kg-1 respectively in Quseir city, Egypt. Concentrations of the metals; Mn, Zn, Cu, Pb, Ni, Co and Cd were determined by Atomic Absorption Spectrophotometry (AAS) using GBC-932ver.1.1with detection limits of 0.01 ppm.
