Abstracts

Evaluation of anthropogenically enhanced naturally occurring radionuclides 238U, 232Th and 40K present in Lagos beach sediment (Eleko and Elegushi) were analyzed with gamma ray spectrometer using a highly shielded NaI (TI) detector with the objective of evaluating the environmental radiological hazard. Mineralogical analysis and characterization was also carried out using Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) technique. Heavy metals such as Pb, Cd, Cr and Fe were analyzed using atomic absorption spectrophotometer. (AAS model: Buck Scientific Model 210VGP and A. Analyst 200 Perkin Elmer).
