Abstract
The problem of radioactive pollution is extremely urgent in Russia in connection with presence of
territories polluted by radionuclides on places of nuclear tests, in zones around the enterprises on production,
processing and storage of radioactive materials, and also in areas of emergency pollution (Barakhtin, 2001).
The aim of our investigation was a determination of the levels of the main radioactive elements - Cs-137 and Sr-90 in diary
products.
363 samples of milk, dry milk, butter, cheese and yogurt from Novosibirsk region were examined.
Cs-137 level was 3.7 ... 9.2 times higher than Sr-90 one in milk, cheese and yogurt. At the same time the level of
these radio nuclides in butter was identical (8.03 Bk/kg).
