You need to be on iodine/iodide which is sold as Iodoral or the liquid version of Lugol’s.
The people of Japan are already going to be pretty protected because they get an avg of 14mg/day of iodine from their diet of fish and seaweed.
We in the US are deficient and need to supplement with this. And, consequently, it will protect you from radiation poisoning.
I actually have Idoral, haven’t been taking it, maybe I’ll start back up, thanks !
