Radioactive source absolute activity determination by means of low
temperature calorimeters and its comparison to established activity
standardisation techniques and high-resolution spectrometry of selected
The aim of this work package is to develop the method to use MMCs for absolute activity determination,
perform measurement on an α emitter (241Am), a β emitter (129I) and an electron-capture nuclide (55Fe) and
compare the results to measurements with established techniques for absolute activity determination.
