Abstract: A study conducted during summer 1993 to determine the bioavailability and transfer of ¹³⁷Cs and ⁹⁰Sr to dairy cattle from herbage collected from a pasture contaminated by particulate fallout is described. The study pasture was located 3.5 km from the Chernobyl nuclear power plant. The true absorption coefficient (A_t) determined for ¹³⁷Cs (0.23) was considerably lower than previous estimates for radiocaesium incorporated into vegetation by root uptake.
