The aim of this study is to estimate the activity concentrations and radiological assessment of soils around high-tension cables, Transmission company of Nigeria, Osogbo, Nigeria. Surface and control soils were obtained around the high-tension cables and from areas far away from the sampling points, respectively. Their radioactivity levels were determined using gamma ray spectrometer. The results showed that the mean activity of the identified radionuclides, <sup>40</sup>K, <sup>238</sup>U and <sup>232</sup>Th are 223.59±11.98, 15.39±1.95 and 4.54±0.28 Bq/kg respectively, in the studied soils while the control soils exhibited activity concentrations of <sup>40</sup>K, <sup>238</sup>U and <sup>232</sup>Th, as 6.22±0.34, 11.58±1.55 and 0.50±0.03 Bq/kg respectively. The radiological indices, ADR (absorbed dose rate), AED (annual effective dose equivalent), H<sub>in</sub> (internal hazard index), H<sub>ex</sub> (external hazard index), AGDE (annual gonadal dose equivalent), I<sub>γr</sub> (representative gamma index) and Ra<sub>eq</sub> (radium equivalent) have values of 19.65 nGy/hr, 0.17 mSv/yr, 0.14 Bq/kg, 0.10 Bq/kg, 140.77 µsvy<sup>-1</sup>, 0.30 and 39.64 respectively. These results revealed that the studied soils exhibited low gamma radiation. Long-term exposure to these radionuclides could pose health threats and is therefore discouraged.
