As I forewarned you earlier, radioactive isotopes ☢️ are notoriously difficult to manufacture, due to their necessarily short half-lives of a few hours or less. You wouldn’t want the likes of Thorium 232 pumping round your bloodstream which has a half-life of over 14 billion years!
However, there seems to be no shortage of Uranium-235 or Plutonium-239 when required for nuclear weapons, so I guess it’s just a question of lack of money invested in the production of these tracers, together with a 20% increase in population and commensurate increase in demand for NHS services.
Why doesn’t the multi-billion pound NHS invest in their own cyclotrons or whatever, (and proton beam machines for that matter), rather than outsourcing them to private companies?
This nuclear medicine, as it is called, is at the cutting edge of technology.
Anyway, I was diagnosed with G7 cancer in January 2018, and I explored all my options until my prostatectomy in June 2018. They say PCa is often slow-growing, and yours probably is, so a few weeks here or there are unlikely to affect your prognosis, but not your nerves!
Best of luck, once again.
Cheers, John.
