摘要

In nuclear forensics, activation products can provide important information about the neutron energies occurring during a fission event. Activation products are difficult to measure since they typically have short half-lives (less than a week), many have low intensity gamma emission, and/ or form in relatively low abundance with respect to fission products. This work focused on separating divalent transition metals (M2+  = Mn, Ni, Cu, and Zn), Pt, and V activation products using extraction chromatography. Both DGA and AN resin were tested with a non-radioactive sample, then DGA resin was used to separate activation products from a seawater matrix containing fission products.
