“…The degree of natural exposure exhibits global variability, typically differing by a factor of approximately [5]. The rates of radionuclide accumulation in vegetables and fruits are contingent upon the type of soil and rock in which they grow [6][7][8][9][10]. Radionuclides enter food crops through various pathways: direct deposition on leaves or exposed plant parts, uptake from soil into roots, re-suspension as dust from soil or other surfaces, and washing into water sources used for irrigation by rain.…”

Natural radionuclides are present in food items at different levels, influenced by factors like background radiation, climate, and agricultural practices. These radionuclides play a crucial role in internal radiation exposure in humans. Notably, radionuclides within the decay series 238U and 232Th as well as 40K are significant concerns in radiation protection due to their prevalence and potential health risks. The activity concentrations of radionuclides 238U, 232Th, and 40K in several food crops consumed within Lagos city in Nigeria were measured using gamma spectrometry. The concentration of 238U, 232Th, and 40K ranged from 0.90 to 55.30, BDL to 161.60 and 10.30 to 1075.20 Bqkg-1, respectively. The average radionuclide activity concentrations are below the worldwide average values set by UNSCEAR in 2000, which are 35, 30, and 400 Bqkg-1 for 238U, 232Th, and 40K, respectively. The study calculated the annual effective dose for individuals consuming the studied food items, and the annual internal dose from ingesting was found to be 8.95×10-04 µSvy-1. It's noteworthy that this computed value is below the worldwide value of 0.32 mSv y-1 set for the public. Additionally, the excess lifetime cancer risk (ELCR) value was 3.13 × 10−3 µSvy-1, which is within the world safe limit value (2.9 × 10−4 µSvy-1). Therefore, there is no potential radiological risk associated with the measured data.
