Natural Radionuclides and Heavy Metals Concentration of Marine Sediments in Quseir City and Surrounding Areas, Red Sea Coast-Egypt

Abstract

Concentrations of natural radionuclides 226 Ra, 232 Th and 40 K 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 226 Ra, 232 Th and 40 K 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.
