This work investigated the utility of UTEVA and TEVA extraction resins for the separation of Th from U. The 230 Th/ 234 U radiochronometer is one “fingerprint” of nuclear material used to verify a State’s compliance with non-proliferation treaties or bi-lateral agreements. Reference materials with s...
