The need for safe habitat in view of the demands of Sustainable Development Goal 3 - sound health and wellbeing, calls for attention to ascertain the level of exposure of gamma radiation to man and the environment. Keeping the levels of specific activities of naturally occurring radionuclides (NORs) within safety limits will help in attaining the Sustainable Development Goal 3-“Good Health and Wellbeing”. Background gamma dose rates and activity concentrations of NORs: 40K, 238U, and 232Th in an agrarian settlement, Ifo-Dagbolu-Ajakaye, Ogun State, Southwest Nigeria, was surveyed using an Ultrarugged Super-spec RS-125 gamma spectrometer. The respective mean values of the background gamma dose rates and specific activities of 40K, 238U, and 232Th were 14.96 nGyh-1; 31.60, 16.54 and 12.91 Bqkg-1. The values of the specific activities were used to estimate the associated radiological health parameters and the values obtained were lower when compared with their corresponding United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) permissible limits. Hence the levels of the activity concentrations of the studied NORs do not present health hazards to the dwellers in the examined station.
