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 average number, , of prompt neutrons emitted in the spontaneous fission of U238 and Pu240 has been measured relative to for the spontaneous fission of Cf252. This reference value is taken to be = 3.80. The measurements have been performed with large liquid scintillators and the results obtained are (U238) = 1.97 ± 0.07 and (Pu240) = 2.154 ± 0.028.
