Abstract: In this study, the measurement of industrial ionizing radiation background was reported in Port Harcourt, Nigeria taking the western Geophysical Industry as a case study. The Geiger Muller Counter and its associated sensors were used to obtain counts of radiation at intervals of 10 min for about 1 h at each site. Count rates for the three chosen locations were 26.98±0.64, 37.19±1.06 and 35.40±1.95 cpm, respectively. The corresponding dose rates were 8.42±0.34, 11.60±0.28 and 11.04±0.30 μRh-1. These values were found to be below the maximum permissible rate of 57 μRh-1 accepted internationally by the National Council on Radiation Protection (NCRP).
