We aimed to determine transfer coefficients for milk, beef, pork in the site of planned construction of the nuclear power plant Kecerovce. During 2 years (February 1987–December 1988) the samples of milk, meat and corresponding fodder were regularly taken. Content of137Cs and90Sr in samples was determined and from the measured values the transfer coefficients were calculated. For the whole period we obtained these transfer coefficients: 2.9-10−3and 4.2 · 10−3d · 1−1for milk, 2.4 · 10−2and 9.2 · 10−3d · kg−1for beef and 3.3. · 10−1and 1.1 · 10−1d · kg−1for pork for137Cs and90Sr, resp. In view of the fact that samples were taken from animals kept under usual breeding practices we suppose that obtained values are suitable for models used in prediction of burden to the population in this site from ingestion of given foodstuffs, especially in the case of milk and beef, because the feed for cattle is grown directly in the studied site.
