Abstract
Dynamical examination of contents of the observed natural radionuclides in
prime foodstuffs demonstrated their relative stability. Generally, 210Pb and 226Ra
specific activities in foodstuffs depend upon the food type and options of
agriculture management. Many-year researches show that average specific
activities of 210Pb and 226Ra for different foodstuffs vary over the range 0.04-0.15
Bq/kg and 0.02-0.08 Bq/kg. Soil dependence of 210Pb and 226Ra contents in
foodstuffs has not been revealed. Taking into account the food patterns of the
Russian population, the highest intake of 210Pb and 226Ra is due to ingestion of
bread, meat and drinking water. Annual effective internal doses are about
50 µSv/a.
Keywords: natural radionuclides, foodstuffs, doses, ingestion, intake.
