Alpha-spectrometric analysis of environmental samples - Spreadsheet approach

The example evaluates the uncertainty sources for the determination of different actinides in environmental samples according to the spreadsheet method and refers thereby to the example prepared for this guide by G. Kanisch. The analytical procedure involves sample preparation steps for drying, ashing and dissolution and further radiochemical separation and electroplating of the isolated radionuclides. The radioactivity is measured by a solid state detector coupled to a multichannel spectrometer. An isotopic tracer is used to determine the overall chemical yield and to ensure traceability to a national standard. (author)
