Abstract

Results of systematic, long-term measurements of 137Cs activities in wheat are summarized. 137Cs fallout activity affected wheat activity the coefficient of correlation being 0.91. A model used by UNSCEAR was used to describe l37Cs transfer from fallout deposition to wheat. The transfer coefficient was calculated to be 6.1 x 10-3 Bq yr kg-1/(Bq m-2). The dose incuned by wheat consumption was estimated for the Croatian population, the annual collective equivalent dose being approximately 550 man Sv for the 1965-1992 period. After the Chernobyl nuclear accident the 134Cs: 137Cs activity ratio in wheat was - 0.5, and did not differ from that for other environmental samples.
