This is pretty cool! I worked for a summer at Chalk River in Canada, and it was crazy that a few suppliers could produce so much of the world's medical isotopes. I remember reading about fears of a Technetium-99 shortage when it does shut down [1].

People are very hesitant about nuclear power, but medical isotope manufacturing requires little enough nuclear fuel that it should be very safe. You sound like the right person to tackle this, and the market is definitely there. Good luck!
