Chris Wagner: The role of Eden Radioisotopes in the future of nuclear medicine
Chris Wagner has more than 40 years of experience in nuclear medicine, beginning as a clinical practitioner before moving into leadership roles at companies like Mallinckrodt (now Curium) and Nordion. His knowledge of both the clinical and the manufacturing sides of nuclear medicine laid the groundwork for helping to found Eden Radioisotopes, a start-up venture that intends to make diagnostic and therapeutic raw material medical isotopes like molybdenum-99 and lutetium-177.

Tritiated waste and glovebox cleanup systems contain significant levels of trititated methane impurities which require reducing and processing to recover the tritium. A viable approach to the recovery of tritium is the conversion of tritiated methane into elemental tritium and carbon by thermal cracking on a heated metal matrix.
Through the conversion reaction of HTO/H2O with hot Al4C3 powder, tritiated methane concentrations in the 0.4 to 0.9 mCi/m3 range are achievable. The HTO/H2O ratio is ~10-7.
Conversion efficiencies for the decomposition of methane are measured for Zr-Fe-Mn alloy, iron oxide and supported nickel catalyst. HT and HTO are created by decomposing methane. Zr-Fe-Mn alloy achieved a maximum conversion efficiency of ~70% at 700°C. Iron oxide thermally cracked methane at 36% at a temperature of 700°C. Supported nickel operating at 450°C achieved conversion efficiencies ranging from 65 to 100%.
