This study compares airborne radiation dose rates with reported in-situ measurements in Gidan-Kwano, Minna, Niger State, Nigeria, using airborne radiometric data. The concentrations of 238U, 232Th, and 40K were mapped, revealing variations across lithological units. Maximum concentrations of 238U, 232Th and 40K were 846.35 Bqkg− 1, 31.84 Bqkg− 1, and 39.49 Bqkg− 1, respectively. Absorbed dose rates from airborne data ranged between 18.20 nGy/h and 68.86 nGy/h, with a mean of 31.65 nGy/h, significantly lower than the reported in-situ measurements, which ranged from 87.00 nGy/h to 252.30 nGy/h, with a mean of 136.75 nGy/h. The airborne data showed lower values than global mean of 59.00 nGy/h. Pearson correlation coefficient showed a weak positive correlation between airborne and in-situ measurements, attributed to factors such as photon attenuation, airborne measurement altitude, and geological variations. An isodose map highlighted higher dose rates in regions dominated by gneiss and granite formations. The findings suggest that while airborne data provide a broader overview, in-situ measurements are crucial for capturing localized variations, essential for radiological health assessments. The study serves as baseline data for future environmental monitoring, especially given recent mining activities in the area.
