“…[67] Several studies in Nigeria have measured the activity concentration of natural radionuclides in soil to ascertain the levels of contamination. [891011121314] It was revealed that staple food stuffs consumed in Nigeria contain traces of radionuclide and as a result of this, refuse dumpsites were identified as a liable recipient in containment of radioactive materials as inhabitants cultivate and plant legumes, vegetables, and so on in the field around the dumpsites. The transportation of heavy metal as well as radionuclides in soil from this sites are possible via root-uptake and then to human through breathing and ingestion.…”

The activity concentration of natural radionuclides in soil samples from industrial dumpsites in Sango-Ota were determined using gamma-ray spectrometry with NaI(Tl) detector. The mean activity concentration of 226Ra, 232Th and 40K was 3.0 ± 1.2, 33.3 ± 9.8 and 122.1 ± 20.6 Bqkg−1, respectively. Radium equivalent activities were calculated to assess the hazards arising from the use of the soil sample in agriculture. All the calculated values were lower than the world average. The mean concentration of heavy metals in the soil samples were 33.6, 2.9, 3.8, 2.7, 48.9, 1,5, 34.5 and 0.8 mg l-1 for Cu, Mg, Ca, P, Fe, Pb, Zn and Cd, respectively. The concentrations of Cd, Cu and Pb were higher than the natural permissible range in soil. Therefore, the government should discourage the use of the soil around dumpsites for planting because of the presence of heavy metals in the sites.

“…Acute doses such as resulting from a serious accident involving nuclear materials can result in damage to the blood-forming organs, gastrointestinal tract, and central nervous system [5,6]. In Nigeria, the risks associated with environmental radioactivity have been carried to determine regional risks across the country [9,10]. The study showed that population in the northern part of Nigeria is associated with high radiation risks than that in the southwestern and Eastern regions [11].…”

A 10 y (1999-2008) birth records from two public and most accessible maternity hospitals locally in the city of Abeokuta, Nigeria were used to investigate the possible association of high outdoor gamma radiation exposure on reproductive abnormalities in the city. From the delivery record of 11,923 births in the period under study, a total number of 485 incidences of reproductive abnormalities were recoded. These incidences comprise 228 multiple births, 190 still births and, 67 premature births. Using the available terrestrial gamma radiation exposure data for the city and different reproductive abnormalities, regression assessment was carried out using the Pearson Product Moment (PPM) correlation statistics. The correlation showed that the incidences of reproductive abnormalities and the radiation dose levels were negatively correlated and correlation coefficient values were very low for each of the reproductive abnormalities considered. Factors such as socioeconomic potentials of patients, dietary and other environmental factors may have substantial influence on the reproductive defects in the area other than radiation. However, the present study has added to the radiometric information needed in understanding the relationship between natural outdoor radiation exposure and occurrences of reproductive abnormalities in areas of high radiation in the country.

“…In the last two decades, many studies have been carried out on the natural background and artificial radiation levels in Nigeria (Oresegun et al, 1990;Obed et al, 2005;Jibiri et al, 1998;Jibiri et al, 2011;Farai et al, 2006;Ademola et al, 2006).…”
