Abstrakt

Here we present a nuclear forensic study of uranium from German nuclear projects which used different geometries of metallic uranium fuel.3b,d, 4 Through measurement of the

²³⁰Th/

²³⁴U ratio, we could determine that the material had been produced in the period from 1940 to 1943. To determine the geographical origin of the uranium, the rare-earth-element content and the

⁸⁷Sr/

⁸⁶Sr ratio were measured. The results provide evidence that the uranium was mined in the Czech Republic. Trace amounts of

²³⁶U and

²³⁹Pu were detected at the level of their natural abundance, which indicates that the uranium fuel was not exposed to any major neutron fluence.
