Vertical Distribution of 238Pu, 239(40)Pu, 241Am, 90Sr and 137Cs in Austrian Soil Profiles
The occurrence of 238Pu, 239(40)Pu, 241Am, 90Sr and 137Cs in the region of Nassfeld (Salzburg, Austria) is discussed
at four different locations by evaluating a depth profile for each radionuclide. Furthermore, the plutonium separated
from the soil samples was measured by Accelerator Mass Spectrometry (AMS) to get information on the isotope ratio
240Pu/239Pu. The radiochemical procedure consisted of a Pu separation step from Am and Sr by anion exchange in 8M
HNO3 after oxidation state adjustment to Pu(IV). Am and Sr were coprecipitated with calcium oxalate. Am was separated
from Sr by extraction chromatography using TRU-resin. The Sr separation was performed also by extraction chromatography
using Sr-resin; after coprecipitation as oxalate, 90Sr was measured in a gas proportional counter. For the determination
of 239(40)Pu and 241Am by a-spectrometry thin sources were prepared by microprecipitation with NdF3.
