N2 - Groundwater encompasses varying natural radionuclides due to their interaction with the rock and soil that differ in geochemical, mineralogical, and chemical compositions. Exposure to these radionuclides can cause significant risks to human health. Thus, this study aims to estimate the annual effective dose equivalents (Dw) and the excess lifetime cancer risks (LCRs) for adults (>17 yr) living in the United Arab Emirates based on the water consumption rate of 285 (L/yr), and the activity concentrations for forty groundwater samples were calculated in a previous study. The annual effective dose equivalents (Dw) of226Ra,232Th, and40K were 2.69 × 10+1 ± 5.64 × 10–1 (µSv/yr), 1.47 × 10+1 ± 4.53 × 10–1 (µSv/yr), and 8.83 ± 1.63 × 10–1 (µSv/yr), respectively, with the total annual effective dose of 5.04 × 10+1 ± 0.74 (µSv/yr). Consequently, the yearly radionuclide intake (Da) was lower than the WHO-specified average limit. The total values of the excess (LCRs) for the226Ra,232Th, and40K were 9.95 × 10–5. Accordingly, the excess LCR values for groundwater were found below the acceptable limit of 10–3 for radiological risk.
