Radiocaesium activity concentrations in milk in the Republic of Croatia and dose assessment

Results of systematic, measurements of 137Cs activities in milk after the Chernobyl nuclear accident are summarized. 137Cs fallout activity affects milk activity, the coefficient of correlation being 0.89. The 137Cs activities in milk in Croatia are log-normally distributed, reflecting the exponential decrease of activity. After the Chernobyl nuclear accident the 134Cs:137Cs activity ratio in milk was 0.5, and did not differ from that for other environmental samples. The dose due to radiocaesium ingestion by milk consumption was estimated for the Croatian population, the annual collective equivalent dose being approximatelly 205 manSv in 1986 and 1.5 manSv in 1994.
