Transfer Factor of Selected Radionuclides from Soil to Plant in Selected Dump Site of Obio/Akpor

Indiscriminate disposal of municipal and industrialized wastes in our environment has raised human exposure to dicey substances that is detrimental to their strength. In this research, radionuclide transfer factor was determined from crops planted forthcoming major dump sites in Rivers State. Samples of foodstuff crops and soil near the dumpsites were composed for gamma spectroscopy. The average activity aggregation of 40K, 238U and 232Th in soil are 115.8717.01 Bqkg-1, 31.547.13 Bqkg-1and 18.776.02 Bqkg-1. While in crop are 403.4613.06 Bqkg-1, 9.544.02 and 22.245.11. In soil, all the radionuclide values were all inside the world average profit and in crop, the values were likewise within the globe average value except that 40K thatwas more prevalent in crop and surpasses the world average worth of 400Bqkg-1. The activity aggregation of radionuclides 40K, 238U and 232Th for transfer factor are 8.187667Bqkg-1, 0.231667Bqkg-1and 2.144333Bqkg-1respectively accompanying potassium having the maximal mean transfer factor that may develop its larger accumulation in crop. Based on this verdict, cassava products refined in dumpsites are not radiologically free and safe for human devouring.
