best i can tell, we are seriously exposed, and a lot of it is out of our hands. i am sure there are some people taking Iodine right now and not getting anywhere due to contemporanious exposure. it could account for some of the more severe reactions. it pays to look hard at ons primary environment. imagine those in retail? look at all the fire retardants in the car industry. my brother works for lazyboy and he does not do well at all. he also eats a lot of pizza hut. he has taken Iodine and it had no effect. it probably all ran right out of him. bad news. cancer territory.
