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.

A recently developed stacked neutron guide system, installed at the Interfaculty Reactor Institute in Delft, The Netherlands, is described. It comprises two 3-m-long stacks of curved narrow neutron guides. This system is designed to transmit thermal neutrons by means of total reflection and, at the same time, attenuate fast neutrons and gamma radiation strongly. Comparison of calculated and measured flux densities shows an excellent transmission of the thermal neutrons. The measured fast neutron and gamma radiation dose-equivalent rates are consistent with the design values.
