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.

To calculate the neutron kinetic energy release parameters (kerma factors) for an element consisting of several isotopes, it is necessary to use separate neutron cross-section and radioactive decay data for each isotope. In the case of chlorine, cross sections for natural chlorine are available, but cross sections for the individual isotopes are not. Kerma factors for chlorine were calculated using natural chlorine cross sections and weighting the contribution of each isotope to the decay data, using the fractional contribution as a variable parameter. The kerma factors calculated at particular neutron energies are found to be sensitive to this parameter and dependent on that energy. The purpose of this Note is to encourage experimental determination of the relevant neutron cross sections of isotopically pure samples of chlorine.
