Abstract
Abstract: 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
