Validation of uranium age-dating method for nuclear forensics with uranium standards

Matsui, Yoshiki; Umino, Yuji*; Shinohara, Nobuo ; Kimura, Yoshiki

Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) of JAEA has been developing nuclear forensics techniques to identify the origin and intended use of nuclear and radioactive materials, and also conducting uranium age-dating as part of this development. Uranium age-dating at ISCN can estimate when the uranium was refined from its raw material by measuring the $^{230}$ Th/ $^{234}$ ratio of the uranium sample. In this paper, we report the results of uranium age-dating on uranium standards to verify the applicability of the age-dating method.
