This research investigated the emission of radiation from refuse dumpsites in some selected areas in Kano metropolis. The readings were taken using Geiger Muller tube detector at gonad level (about 1 meter above the ground level) and at an interval of 5m away from point of reference up to 20m in five sampling locations; coded as RD1, RD2, RD3, RD4 and RD5 respectively while the natural radioactivity concentrations were determined using a gamma ray spectrometer with two calibration point sources, Cs-137 and Co-60. The results indicated that the ranges of activity concentrations of 40K, 226Ra and 232Th in the samples were 304.66 – 460.96 BqKg-1, 18.57 – 32.72 BqKg-1 and 12.22 – 53.63BqKg-1 respectively. The highest activity concentration of 226Ra, 232Th and 40K were found to be 32.72±3.12 Bqkg-1, 53.63±3.49 Bqkg-1 and 460.96±7.78 Bqkg-1 respectively which obtained from RD2 and RD4 locations. However, the highest magnitude of Radium Equivalent Dose (Req.) of 137.60 Bqkg-1 at RD2 was found to be below the permissible limit of 370 BqKg-1 as recommended by UNSCEAR, (2000). Moreover, the highest average value of the background radiation detected at RD1 and RD3 was 0.414mSv/year which is below the ICRP (2006) bench mark of 3.0mSv/year. Therefore, the radionuclide activity concentration and the average exposure rate may not be hazardous. These results will help the health and environmental agencies in developing waste management systems.
