Iodine 131 has a half life of about 8 days. There will be bugger all
Iodine 131 from Fukishima still about let alone Chernobyl.

But they give iodine tablets to those exposed.
What does I131 decay to?
wiki should tell you. No it isn't radioactive IIRC.

Yep.99% turns into xenon 131. Stable and chemically inert.
I 131 is only dangerous for a natter of day or weeks.

It is probably the one valid* reason to evacuate around nuclear
containment breach sites after issuing with iodine tablets.




Is it also radioactive? If so, what in turn is
its half-life?

... growth hormones, antibiotics fed to cattle, etc.

Those and pesticide residues or break down products of any of them, are
far, far greater risk.


*there being lots of politically knee-jerky invalid reasons as well.
