Popis: One of the major sources of human exposure to radionuclides could be from ingestion of food crops grown on contaminated soil. This work is aimed at assessing the level of health risk associated with the intake of238U, 226R, 232Thand 40K in yam and cassava cultivated in farm lands in Akwa Ibom State. The activity concentration of naturally occurring radionuclides in the samples, were measured using a High Purity Germanium (HPGe) Detector. The mean activity concentrations of radionuclides in yam were 2.81±0.42 Bq/kg, 1.02±0.36 Bq/kg, 0.82±0.15 Bq/kg and 335.23±17.20 Bq/kg for 238U, 226Ra, 232Th and 40K respectively. Mean activity concentrations of radionuclides in cassava were 3.29±0.46 Bq/kg, 1.15±0.29 Bq/kg, 1.38±0.18 Bq/kg and 272.65±14.40 Bq/kg for 238U, 226Ra, 232Th and 40K respectively. The estimated mean values of external hazard index (Hex) and internal hazard index (Hin) were 0.08, 0.07 and 0.11, 0.08 respectively in cassava and yam respectively. The estimated mean values of gamma absorbed dose rate in yam and cassava were 15.71 -1 and 13.66 -1 respectively. The mean values of Annual effective dose (AED) due to consumption of cassava and yam were 0.070 µSv yr-1 and 0.186 µSv yr-1, respectively. The mean estimated values of excess lifetime cancer risk due to consumption of cassava and yam were 0.00019 and 0.00022, respectively. The values obtained for the radiological doses for the yam and cassava samples were below the world recommended values. It is recommended that farmers should be educated to only apply the right types and quantities of fertilizers to soil in order to check further increases in concentration levels of these radionuclides in soil and plants.
