This paper describes rapid methods for the determination of the production date (age dating) of plutonium (Pu) materials by inductively coupled plasma mass spectrometry (ICP-MS) for nuclear forensic and safeguards purposes. One of the presented methods is a rapid, direct measurement without chemical separation using U-235/Pu-239 and U-236/Pu-240 chronometers. The other method comprises a straightforward extraction chromatographic separation, followed by ICP-MS measurement for the U-234/Pu-238, U-235/Pu-239, U-236/Pu-240 and U-238/Pu-242 chronometers. Age dating results of two plutonium certified reference materials (SRM 946 and 947, currently distributed as NBL CRM 136 and 137) are in good agreement with the archive purification dates.
