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 investigate a new approach for resonance self-shielding calculations, based on a simplified and straightforward subgroup model, used in association with an improved Santamarina-Hfaiedh energy mesh. This subgroup model relaxes the need to represent the correlated slowing-down effects by optimizing the energy mesh. The resulting equations become sufficiently simple to reintroduce an accurate representation of other physical effects that are generally neglected, namely, the mutual shielding effect between different isotopes and the temperature correlation effect caused by an explicit temperature gradient in a resonant isotope. The resulting self-shielding model is shown to reach levels of accuracies that are similar to those of a Monte Carlo method.
