Concentration Of The 241Pu In Air Samples From Chernobyl At Belgrade Site Estimated By a 241Am In Growth Method
Апстракт
The surface air samples collected in the first half of May 1986 at VinčaBelgrade site were prepared and measured at the end of the 1991 and beginning of the 1992. year. Activity concentrations of the 137Cs immediately after the Chernobyl accident were determined by means of gamma spectrometry, while the air activity concentration of 238Pu and 239,240Pu were determined by alpha spectrometry, after the plutonium radiochemical separation. The 236Pu was used as a tracer. The same samples were remeasured after 13 years, during the 2004. The surface air activity concentrations of 241Pu were estimated by a 241Am in-growth method. The built up activities of 236Pu progenies were determined from the recorded spectra and also calculated using the Bateman’s equations. The 241Am activity in the remeasured samples, obtained by complex spectral analysis was confirmed by gamma spectrometry. The 241Pu activity concentration in measured air samples ranged from 240 µBq/m3 to 7800 µBq/m3 . The average ac...tivity concentration ratio 241Pu/239,240Pu originated from Chernobyl accident was approximately 100.
