Radioactive concentrations of Sr-90 and Cs-137 in the diet of Polish residents over five years: 2020–2024

The nuclides examined in this study, Sr-90 and Cs-137, are artificial radioactive isotopes, and their presence in the European environment is primarily associated with radioactive fallout from the 1986 Chernobyl disaster. Since ingestion is one of the main pathways for the intake of radioisotopes into organisms, the radioactive concentrations of Sr-90 and Cs-137 in the diet of Polish residents were studied. To estimate the intake of Sr-90 and Cs-137 through food, their levels in daily meals were measured annually in Warsaw, the capital city of Poland. The radioactive concentrations measured ranged from 0.03 to 0.07 Bq/day for Sr-90 and from 0.06 to 0.23 Bq/day for Cs-137. The combined effective doses from Sr-90 and Cs-137 varied between 0.69 and 1.60 μSv/year.
