Primary activity measurement of an Am-241 solution using microgram inkjet gravimetry and decay energy spectrometry
Ryan P. Fitzgerald, Bradley Alpert, Denis E. Bergeron +11
We demonstrate a method for radionuclide assay that is spectroscopic with 100 % counting efficiency for alpha decay. Advancing both cryogenic decay energy spectrometry (DES) and dr…
