ACTIVITY CONCENTRATION FOR SURFACE SOIL SAMPLES COLLECTED FROM ARMANT, QENA, EGYPT

Thirty four surface soil samples were collected from four directions in Armant area. Qena, Egypt to measure their natural radioactivity concentrations due to Ra�226, Th�232 and K�40 radionuclides. Soil samples were analyzed by using lowlevel gamma� spectrometric analysis. The average activity concentration for Ra�226 was found to be 27.3±3.2, 11.4±1.09, 10.6±1.2, and 11.4±1.02 (Bq/kg) while the average value for Th�232 was 15.1±1.4, 11.1±0.77, 10.8±0.72 and 11.1±0.8 (Bq/kg) for soil samples from North, South, West and East. The corresponding average values for K�40 were 521.4±16.8, 463±14.8 488.9±15.6 and344.5± 10.7 (Bq/kg), respectively. Based on radionuclides concentration in soil samples the radiological effects were assessed.
