Measurement of Natural Radioactivity in the Soil of Kufa City-Iraq
Abstract
The natural radioactivity in soil has been determined by using gamma-ray
spectroscopy technique. The (average) and (range) of specific activity (in Bq/kg
units) of the primordial nuclides were (8.73) (1.82 to 24.71), (4.75) (1 to 9.44) and
(103.05) (47.27 to 206.67) for 238U, 232Th and 40K respectively. The value of Radium
equivalent activity (in Bq/kg units) was found to be varied from 11.54 to 42.61 with
an average of 23.47. The absorbed dose calculations (in nGy/h units) showed that the
minimum value was 5.57 whereas the maximum value was 20.07 with an average of
11.28. The indoor and outdoor annual effective dose rate (in
