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.
