The rare isotopes 236 U and 239 Pu are produced naturally by neutron capture in uranium ores. Here we measure 236 U and 239 Pu by accelerator mass spectrometry (AMS) in the same ore samples for the first time. To ensure efficient extraction of both elements and isotopic equilibrium between the 239 P
