TRANSFER OF CS-137 AND SR-90 TO SOME ANIMAL PRODUCTS IN THE SITE OF PREVIEWED NUCLEAR-POWER-PLANT CONSTRUCTION

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 of Cs-137 and Sr-90 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(-3) and 4.2.10(-3) d.l-1 for milk, 2.4.10(-2) and 9.2.10(-3) d.kg-1 for for beef and 3.3.10(-1) and 1.1.10(-1) d.kg-1 for pork for Cs-137 and Sr-90, 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.
