Abstract
ABSTRACT
A ground survey was conducted for the investigation of the amount of radioactivity
in Kufena, Zaria, northwest Nigeria. The technique of gamma ray spectrometry
was applied using Scintillometer and gamma ray spectrometer (DISA-300). Activity
concentration levels due to K, U, and Th were measured in the area along profiles
spaced at 50 metres. Activity concentration ranges of the concerned radioelements
were as follows: K was 0.03 – 6.5 %, U was 23.4 – 64.1 ppm, and Th was 8.3 –
89.1 ppm. The study identified Uranium and thorium as the main sources of
radioactivity in the rocks of the area while potassium is not a major contributor to
the gamma ray activity observed in the field. The study also revealed that uranium
mineralization in Kufena may be of low grade.
