Radiochemical analysis of aerosol filters and precipitation samples by the German Weather Service
Description
The German Weather Service routinely analyses air and precipitation samples for the isotopes U-234, U-235, U-238, Am-241, Pu-238, Pu-239/240, Sr-89 and Sr-90. In the presented method, the separation of alpha emitters and strontium isotopes from the same sample is done by a multi-stage extraction chromatography procedure. Alpha-emitting nuclides are electrodeposited and measured by alpha spectrometry, Sr-89 and Sr-90 will be simultaneously determined using a three-window LSC-method. The analysis procedure is used in routine operation, as well, with minor modifications in the intensive operation.
