“…For 238 U, 232 Th, and 40 K, the coefficient of effective dose is 4.50 × 10 -8 Sv/Bq, 2.30 × 10 -7 Sv Bq −1 and 6.20 × 10 -9 Sv Bq −1 respectively (ICRP, 2012). The average consumption rate of 179.9 kg yr −1 and 79.8 kg/yr for cereals and vegetables, is applied to estimate the food crop's annual effective doses and 600 l/yr for water [32,33].…”

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.

The current study presents a radiological water-quality assessment on 64 spring water samples from four Romanian counties. The study area is abundant in CO2-rich spring waters consumed by locals and tourists. Gross alpha activities ranged between 21 ± 2 and 7530 ± 658 mBq L−1, with 27% of the samples exceeding the WHO threshold. Gross beta values ranged from 40 ± 2 to 5520 ± 430 mBq L−1, with 29% exceeding the recommended values. Radionuclide activities fluctuated between 0.6 ± 0.08 and 81 ± 6 Bq L−1 for 222Rn, 15 ± 2 to 1154 ± 112 mBq L−1 for 226Ra, and from 18 ± 2 to 64 ± 5 mBq L−1 for 210Po. The annual effective doses attributed to radium varied between 0.002 and 0.23 mSv yr−1.
