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.

The ability to efficiently model coupled electron-photon transport is essential for determining the response of electronics components to nuclear radiation environments. Furthermore, to fully characterize the effect of many different radiation environments on a component, an adjoint transport capability is desirable. The theory of adjoint electron-photon transport is described with the CEPXSZONEDANT-LD discrete ordinates code package and the method is applied to a set of example problems representative of those encountered in radiation effects testing. Adjoint transport, in addition to efficiently modeling radiation source variations, can effectively model geometry variations for certain classes of problems. A new linear-discontinuous approximation of the continuous slowing down operator that introduces no upscatter is also developed.
