(...) how they believe those countries can achieve medical procedures we use every day in hospitals and labs (not including Universities and other research facilities) without radioactive isotopes. Things like X-Rays, Chemotherapy, CT scans, and everything else found in a Nuclear Medicine office (which is a pretty long list).
I agree with pretty much everything you said, but you picked up precisely the wrong examples.
X-ray machines and CT scanners (which are essentially an x-ray tube and detector mounted on a rotating gantry) do not contain any radioactive material whatsoever. Yes, they emit ionizing radiation (in the form of x-rays), but it is not originating from a radionuclide. Other types of tomographic scanners such as PET and SPECT do employ radionuclides injected into the patient, but you precisely didn't mention those.
And chemotherapy... again, that uses chemical agents to treat cancer, not radioactivity. Yes, there is radiotherapy, which in some cases (but not always) relies on radionuclides to deliver an ionizing radiation dose, but again you failed to mention it.
