摘要：

A radiochemical procedure is described for the simultaneous determination of238Pu,239+240Pu,241Pu,241Am,242Cm,244Cm,89Sr, and90Sr in vegetation samples. The method was applied for the determination of these, radionuclides in grass, collected near Munich after the fallout from the reactor accident at Chernobyl, USSR. The specific activities observed were (in Bq kg-1 dry weight):238Pu, 0.077;239+240Pu, 0.15;241Pu, 3.9;241Am, 0.031;242Cm, 3.0;244Cm, ≤0.008;89Sr, 2000;90Sr, 99. © 1990 Akadémiai Kiadó.
