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.

Electrical conductivities of weakly ionized nuclear plasmas were computed by numerically solving an electron Boltzmann equation. A pure 3He gas and 3He-Na gaseous mixtures were analyzed. The gases are ionized by fast ions (0.19-MeV tritons and 0.59-MeV protons), which are generated from in situ neutron-3He nuclear reactions. The results show that the electrical conductivity of the 3He-Na gaseous mixtures is higher than that of the pure helium gas because of the enhanced ionization of seeded sodium atoms by subexcitation electrons. This effect is not included in a standard Maxwellian model. An analytical formula of W values for gaseous mixtures was suggested to incorporate the effect of subexcitation electrons. The formula can be applied to analyze chemically complex systems.
