Well, now you do know. In fact, it's been used for several decades, so it's
not nearly as new as lots of other cancer treatments. It does the same thing
for cancer-thyroids that it does for hyper -- kill it off, though the hope
for cancer is to totally kill off (ablate) any remnants left after surgery
rather than just dial-it-down a bit.
We get to drink a solution or take <1 or more> pills of I-131. It's not like
external beam, where the rays are aimed at you (& about which I hope I never
need to learn more), it's ingested (what fun, drinking nuclear waste!) If
it's for a diagnostic scan, it's a small dose (like 2-5mci, I think). Cancer
treatment can be anwhere from about 30mci up to several hundred.
Sometimes a pre-treatment scan is done with I-123. I remembered
once earlyish-on to ask about the scanning camera & learned it's gamma.
When the radiation safety officer came to measure me before I was let out of
hospital isolation, I was *very disappointed* that his detector didn't
clacketyclack like the ones on TV.
