Abstract
In this study, the naturally occurring radionuclides and their associated radiological hazards were assessed in commonly consumed nuts in Ile-Ife, South west, Nigeria. Samples of different species of nuts were obtained in Ile-Ife, Osun State, Nigeria and their activity levels were determined using gamma ray spectrometer. The results showed that the mean activity of the identified radionuclides, 40K, 232Th and 238U are 67.36, 37.32 and 3.88 Bq/kg respectively. The radiological indices, ADR (absorbed dose rate), AEDR (annual equivalent dose rate), Hin (internal hazard index), Hex (external hazard index), AGDE (annual gonadal dose equivalent), Iγr (representative gamma index) and Raeq (radium equivalent) have values of 22.39 nGy/hr, 0.19 mSv/yr, 0.23 Bq/kg, 0.12 Bq/kg, 152.66 µsvy-1, 0.33 and 48.04 respectively. The radiological assessment suggests that there are no radiological hazards associated with the consumption of the nuts.
