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.

We present two methods, one iterative and the other direct, for the solution of the integral transport equation for monoenergetic neutrons in a three-dimensional finite system, made up of isotropically scattering and multiplying inhomogeneous materials. The methods are suggested by the physical characteristics of criticality, seen in the light of the mathematical concept of the dominance of the fundamental positive flux distribution. Additional results concern the lifecycle point of view for neutron chain reactions, the critical importance function, and the uniform convergence of the Neumann series in all subcritical cases.
