Ground scintillometric investigations of parts of Kerri-Kerri formation, south – west Gombe, north - eastern Nigeria

Abstract

A ground scintillometric survey was carried out in the south - western part of the Kerri - Kerri Formation to identify areas of more prominent radioactive anomalies for further detailed spectrometric investigation. The total count rates recorded were generally higher in the south – western part of the study area. Analysis of the reduced data reveals the threshold activity value for the study area is 27.5 cps. Activities of more than twice the mode that will be of significance in terms of mineralization is 40 cps observed in the area north east of Tumu village with occurrence of granitic feldspar. The cosmic ray contribution to the ground activity measured in the field and used for the background correction is 4 cps. Detailed ground spectrometric investigation should be carried out in the area north – east of Tumu village to determine the radiometric mineralization potentials of the area and confirm if the radiation is due to the rocks or soil of the area.
