Abstract
Concentrations of radionuclides in surface soil across the Nile Delta, the north coast of Egypt, and Middle Egypt have been measured using a hyperpure germanium spectrometer. The concentrations obtained for 40K, the 232Th series, and the 226Ra series are expressed in Bq kg−1 of dry weight, and the exposure rates are expressed in nGy h−1 of wet weight. The activity concentrations of 137Cs in soil are expressed in Bq m−2.
