Can potassium iodide be useful for nasa during space missions?

It has been said that potassium iodide can help to block harmful radiation. I take it about once or twice a week. It does have some great health benefits. In particular; it helps contribute to a healthy thyroid. But I have heard that this supplement has been recommended during a possible nuclear attack. So I would assume it could help block cosmic radiation as well, could it not?
I don’t take high doses since thats not recommended. I also know that you are not supposed to take it everyday as you would a vitamin or mineral.

The whole thing with taking iodine after a nuclear attack is to help prevent the body from absorbing radioactive iodine that’s prevelant in fallout. It doesn’t block radiation; it just prevents the body from retaining a particular radioactive isotope.
Since taking iodine doesn’t block anything, it won’t protect astronauts in space from cosmic radiation. Cosmic rays are emitted by the sun and are very high energy particles and waves that are very hard to stop.
