Abstract

Natural radioactivity in soil and rock samples from different geologicalstructures in selected locations within the Greater Accra Region of Ghanahas been studied using gamma-spectrometry. Results indicated that the majorcontribution to terrestrial background radiation is the natural radioactiveseries notably ⁴⁰K, ²³⁸U and ²³²Th. Estimatedexposure rate at 1 m above the soil surface ranged from 0.9 to 20.6 µR/hin soils and 0.6 to 17.8 µR/h in rocks. Granitic rocks at Dodowa containhigher levels of the naturally occurring radioactive elements. The relativelylow concentration around the Shai Hills may be due to the predominance ofsand.
