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.

Based on the maximum entropy principle used to reconstruct the neutron flux distribution in nodal calculations, an improved method that utilizes Lagrange multipliers and incorporates corner-point fluxes is described. The probability distribution that maximizes the entropy provides the most unbiased objective probability distribution within the partial information known. The flux distribution on the boundary of a fuel assembly is transformed into the probability distribution in the entropy expression. The most objective boundary flux distribution is then deduced by numerical evaluation of the Lagrange multipliers. This boundary flux distribution is used as the boundary condition in an embedded heterogeneous assembly calculation to provide the detailed flux distribution.
