Medical isotopes have a very short half life for obvious reasons - you don't want to put stuff into people which are radioactive for very long. This means you don't have long to get them from the reactor to the patient. There is a great article about it here: https://world-nuclear.org/information-library/non-power-nuclear-applications/radioisotopes-research/radioisotopes-in-medicine.aspx https://world-nuclear.org/information-library/non-power-nucl... > For PET imaging, the main radiopharmaceutical is fluoro-deoxy glucose (FDG) incorporating F-18 – with a half-life of just under two hours – as a tracer. A relative recently had a PET scan and I was fascinated to learn from the hospital staff that the radio-isotopes in use are couriered around the country by motorbike to get them to the scanners on the morning of the scan. So a nice small fusion reactor to make them sounds very useful for medical reasons, if not the fusion power breakthrough the title made me think!
