This study presents result of external and Internal Hazard indices from the soils samples collected from different
locations around a superphosphate fertilizer factory in Nigeria. An efficiency and Energy calibrated high purity
germanium detector was used to carry out the study while gamma vision software was used for the spectrum
analysis. The Activity Concentrations of the soil samples collected from the different locations in the factory ranges
from 48.99±7.47 to 520.37±20.46 BqKg-1 for 234U, 55.32±7.59 to 215.18±8.70 BqKg-1 for 232Th, and 101.32±13.34
to 476.04±28.07 BqKg-1 for 40K respectively. The internal and external hazard indices for most of the locations are
greater than unity which requires radiological attention for protection.
