N2 - We have recently extended our accelerator mass spectrometry (AMS) system to the detection of actinides for geophysical applications, taking 236U as an interesting test case for this class of nuclides. We report on the development of the experimental setup and on preliminary measurements of 236U in minerals and uranium standards. The isotopic abundance sensitivity is 1 × 10-11. The natural 236U abundance of five U-rich minerals were measured to be between 1 and 33 × 10-11. 236U is expected to be produced in situ by neutron capture on 235U. Three uranium standards material were measured and showed a large 236U contamination.
