Abstract

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.
