NATURAL RADIOACTIVITY LEVELS IN SURFACE SOIL OF KITCHENER DRAIN IN THE NILE DELTA OF EGYPT

In order to initiate a radiological assessment program and to establish a baseline map of radioactivity background levels in the surrounding environment, the activity concentration of radionuclides in surface soil samples around Kitchener Drain area in the North Nile Delta at the coast of Mediterranean Sea were measured by using Y-ray spectroscopy. The activity concentrations was found for 40K ranged from 17.05 to 99.15, for 232Th series ranged from 1.23 to 32.15 and for 238U series ranged from 1.61 to 50.90 (Bg/kg). The Contents in (ppm) of these radionuclides were obtained. The absorbed dose rate in (nGy/hr) due to the natural radioactivity of the samples under study was found to be in the range of 1.73 nGy/hr to 47.03 nGy/hr.
