Radioactive Concentrations of Sr-90 and Cs-137 in the Diet of Polish Residents Over Five Years: 2020–2024
Year: 2025
Type: article
Study design: Observational Study
Abstract: The nuclides examined in this study, Sr-90 and Cs-137, are artificial radioactive isotopes, and theirpresence in the European environment is primarily associated with radioactive fallout from the 1986Chernobyl disaster. Since ingestion is one of the main pathways for the intake of radioisotopes intoorganisms, the radioactive concentrations of Sr-90 and Cs-137 in the diet of Polish residents werestudied. To estimate the intake of Sr-90 and Cs-137 through food, their levels in daily meals weremeasured annually in Warsaw, the capital city of Poland. The radioactive concentrations measuredranged from 0.03 to 0.07 Bq/day for Sr-90 and from 0.06 to 0.23 Bq/day for Cs-137. The combinedeffective doses from Sr-90 and Cs-137 varied between 0.69 and 1.60 μSv/year.
