    "abstract": "Results of systematic measurements of Sr-90 activity concentrations in milk\nfor the period 1961 - 2001 are summarized. An exponential decline of\nradioactivity followed the moratorium on atmospheric nuclear testing. The\nhighest activity of Sr-90 deposited by fallout, being 1060 Bq/m2, was recorded\nin 1963, while the peak Sr-90 activity concentration in milk, 1.42 +/-0.17\nBq/L, was recorded in 1964. The values in year 2001 for fallout deposition and\nmilk were 7.7 Bq/m2 and 0.07 +/- 0.03 Bq/L, respectively. The reactor accident\nat Chernobyl caused higher Sr-90 levels only in 1986. Sr-90 fallout activity\naffects milk activity, the coefficient of correlation between Sr-90 fallout\nactivity and Sr-90 activity concentrations in milk being 0.80. The transfer\ncoefficient from fallout deposition to milk was estimated to be 2.5 mBqy/L per\nBq/m2. The dose incurred by milk consumption was estimated for the Croatian\npopulation, the annual collective effective dose in 2001 being approximately\n2.0 man-Sv.",
