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 atmospheric dispersion model (Tritium-EESAD) was further modified so as to be able to predict tritium concentration in plant tissue free water (TFWT), organically-bound tritium (OBT) and groundwater. The modified model was validated by participating in the Pine Tree Scenario of the IAEA EMRAS program. Monitoring data were disclosed after submission of model predictions and compared with them. Overall time trends of the predicted tritium concentrations in almost all calculation endpoints agreed well with those of observations within a factor of two.
