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 simple yet accurate approximation for calculating spectrum-averaged beta-particle energies and spectra is presented. It gives the average beta-particle energy as a ratio of two polynomials and can be easily implemented on pocket calculators. The values calculated by this method differ from those calculated by “exact” methods by <1% for nuclides with atomic numbers in the 20 to 100 range emitting beta particles having energies up to ∼8 MeV (∼1.3 pJ).
