abstract = "The surface air activity concentration of Pu-241 for the period May 01-15, 1986, for a monitoring site in Vin a, Belgrade was retrospectively estimated. The results were obtained by re-measurement of plutonium fraction alpha-spectrometric sources, with 236 Pu as a tracer, used almost 13 years earlier for the determination of Pu-239,Pu-240 concentration in surface air immediately after the Chernobyl accident. The estimated Pu-241 concentration, based on the Am-241 in-growth method for air samples, ranged from 240 to 7800 mu Bq/m(3). The average activity ratio Pu-241/Pu-239.240 originating from the Chernobyl accident at Belgrade site was approximately 100 at the collection time. (c) 2006 Elsevier Ltd. All rights reserved.",
