Abstract

Naturally occurring radionuclide materials are usually absorbed by plants through their root systems as nutrients, which in turn pose a radiation risk to humans when they consume the plants as food. This study evaluated the radionuclide risks from naturally occurring radionuclides in samples of commonly consumed vegetables in Owerri. Gamma ray spectroscopy was used to analyze and profile the ²²⁶Ra, ²³²Th and ⁴⁰K levels in the vegetable samples of African basil, water leaf, uziza leaf and bitter leaf which are commonly consumed vegetables in Owerri, south-eastern Nigeria. No artificial radionuclides were observed in all the vegetable samples. The ⁴⁰K level was found to be lower than the permissible level for all the vegetables while values above the permissible levels were observed for ²²⁶Ra and ²³²Th. We subsequently evaluated the Activity concentrations, Absorbed Gamma Dose Rate (D_R), Annual Effective Dose Equivalent (AEDE), Excess Lifetime Cancer Risk (ELCR). The range for the activity concentrations were, 193.86 to 391.05 for ⁴⁰K, 12.54 to 43.07 for ²²⁶Ra and 91.92 to 111.27 for ²³²Th. Although the absorbed dose (D_R) was almost twice the world average value, ELCR were lower than the permissible values indicating consumption safety for those who do not rely heavily on the consumption of these common vegetables.
