Natural Radioactivity Levels of Soil Samples from Nile Islands in EL-Mynia Governorate, Egypt

Abstract

© 2016 SERSC. The activity concentrations of 226Ra, 232Th and 40K in twenty - one soil samples collected from five Nile Islands in EL-Mynia governorate have been measured by gamma ray spectroscopy. These islands are used for tourist and agricultural activities. The average activity concentrations of 226Ra,232Th and40K ranged from 14±0.8 to 21±1, 10±0.5 to 23.3±1 and 356.5±18 to 411±20.5 BqKg-1 respectively. The radiological hazards [radium equivalent (Raeq), dose rate, annual effective dose (AED), external hazard (Hex) internal hazard (Hin), gamma radiation hazard index (Iγr) and excess lifetime cancer risk (ELCR)] for tourists and farmers were calculated. The data were discussed and compared with those given in the literatures.
