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.

An imaging plate (IP) was applied to measure tritium in high 60Co gamma-ray radiation fields. The IP made of europium-doped BaFBr(I), a photostimulated luminescence (PSL) material, is a two-dimensional radiation sensor. The PSL response of the IP has a peak at 20-50 keV and steeply decreases towards higher energy, falling by one hundredth at around 1 MeV. By utilizing a large difference in the PSL response to photon energy between 60Co (1.173 and 1.333 MeV) and tritium (maximum energy of 18.6 keV), the bremsstrahlung X-ray induced by tritium beta ray was detected in mixed radiation fields with tritium and 60Co, varying 60Co dose rate in the range 0.0013 to 9.22 Gy/min. It was found that the effect of 60Co irradiation to PSL value, obtained by irradiated with tritium of 12.5 MBq, was negligible by dose rate of 4.38 Gy/min and there was only 7.0% difference of PSL value, obtained by irradiated with tritium of 100 MBq, between dose rate of 0.0013 and 9.22 Gy/min. The IP tritium measurement method can be a promising candidate to measure tritium in high gamma-ray radiation fields.
