This paper presents the results of soil investigations conducted in the Aktobe region to determine the radionuclide content, radon concentration and gamma exposure dose rate. The study shows no excess of health-based exposure limits. However, the excess of radon concentration was registered at the site of land allocation for average global construction, and the radionuclide content (226Ra, 232Th, 40ĂŠ) in the soil of some regions was higher than the worldwide background (percentage abundance) and multi-year average data for the Russian Federation and Kazakhstan.
