Abstract The specific activity and the gamma radiation dose rates due to naturally occurring radioactive materials ((238)U, (232)Th and (40)K) were determined in 26 roadside surface soils along Jamshedpur-Musabani road-a mineralised and mining region, using high-resolution gamma-ray spectrometry. The concentrations of (238)U, (232)Th and (40)K in the soil samples were found to be in the range of 16.6 +/- 0.6-390.5 +/- 1.6, 24.1 +/- 0.7-148.2 +/- 2.1 and 85.9 +/- 3.8-881.6 +/- 22.4 Bq kg(-1), respectively. The annual effective dose equivalent was found to be in the range of 0.04-0.32 mSv y(-1) with an average value of 0.13 mSv y(-1). The excess cancer risk is in the range of 0.16 x 10(-3)-1.22 x 10(-3) with an average value of 0.49 x 10(-3).
