Attainment and sustenance of SDG3-sound health and well-being is a worthy pursuit in ensuring a radiologically safe environment. It has been reported that of all sources of ambient radiation exposure, 80% of the annual average effective dose to man are caused by naturally occurring radionuclides (NORs) and this could pose risk health wise. It is pertinent to appraise the level of radiation exposure to humans and the habitat. This study measured radioactivity levels in the living environment and in soil and sediment samples in terrestrial Agege-Abattoir and freshwater aquatic Agege-Matogbun stations, respectively. The effect of NORs 40 238 232 K, U, Th on the study area was assessed. Ambient gamma doses per unit time and activities per unit mass of NORs were measured employing portable RS-125 gamma spectrometer from Radio Solution and gamma spectroscopy of soil and sediment samples were performed using Hyper-Pure Germanium HP(Ge) gamma detector from Canberra Industries. Radiological risk indices were estimated from gauged and analysed activities per unit mass of NORs. From the in-situ measurements, average values ambient gamma doses per unit time, activities per unit mass of NORs and radiological health risk indicators were found to be lower than their corresponding permissible limits. However, activity concentrations of 238U and 232Th in soil samples were higher than their permissible limits by factors of 1.42 and 1.81;
