Abstract:

The activity concentrations of naturally occurring radionuclides (238U, 232Th and 40K) were investigated in gold ore mined from Birnin Gwari Artisanal Goldmine in Kaduna state Nigeria using Instrumental Neutron Activation Analysis (INAA) technique. Twelve samples were collected from pits at different depths and the locations of pits were marked out using Global Positioning System (GPS). The measured activity concentration due to 238U range from 6.183.7 to 66.694.9 Bq/Kg with mean value 37.365.45, Bq/Kg 232 Th range from 16.650.8 to 87.291.2 Bq/Kg with mean value of 62.696.33 and 40K range from 85.134.5 to 1564.6957.9Bq/Kg with a mean value of 997.5211 9.97 Bq/Kg. The value compared well with published data from other countries and all values from this study are higher than the world average values and other countries with the exception of 232Th concentration from India and Malaysia that are slightly higher than the mean value of 232Th obtained in this study.
