ABSTRACT

Samples of soil were collected at three (3) sites in the Zaria region, northwest part of Nigeria.The elements determined in different soil samples of areas of interest using instrumental neutron activation analysis (INAA) method are Co(5.85ppm), Cr(28.87ppm),Mn(321.65ppm), Th(45.35ppm), U(37.53ppm), V(28.55ppm), and Zn (58.61ppm).Generally, neutron activation is most reliable tool for determining the concentration of heavy metals by measuring the gamma rays released from the decay of the radioisotopes created from the interaction of (neutrons with atoms. In this study, the soil contamination level of all heavy metals and trace elements were compared to the range, mean, and median values of the World soil.Heavy metals such as Th and U have values greater than the world median value.
