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.
利用高纯锗光谱仪测量了尼罗河三角洲、埃及北部海岸和埃及中部表层土壤中的放射性核素浓度。所测得的40K、232Th系列和226Ra系列的浓度以干重Bq kg-1表示，暴露率以湿重nGy h-1表示。土壤中137Cs的活度浓度以Bq m-2表示。
