I recommend you follow the blog posting of Dr. David Brownstein: http://drdavidbrownstein.blogspot.com/ about the radiation issue from Japan.

Dr. Brownstein is one of the national experts about nutritional iodine and our bodies’ need for it.

In addition, now is the time to be taking your good nutritional supplements as well as eating many and a wide variety of vegetables and fruit to assist in protecting from the other forms of radiation besides radioactive iodine.
