Committed effective dose and lifetime cancer risk due to ingestion of natural radionuclides in grains grown in an area of high background radiation

Radioactive isotopes 40K, 137Cs, 226Ra, 228Ra, 234Th in algae supplements – Potential radiotoxicity of aquatic superfoods

“…The estimated morbidity risk presented a magnitude of 10 -4 -10 -9 , while the mortality risk of 10 -5 -10 -9 -the highest in the case of 40 K and the lowest in the case of 137 Cs (Table 3). This highest value indicates a chance of cancer in 1 person in a group of one ten thousand people and was at least ten times lower when compared to excess lifetime cancer risk values calculated for typical food products (10 -3 -10 -6 ) (Silva et al, 2021).…”
