self-protection

Since we are all concerned with radiation here, perhaps it is time to share what one is doing to prevent, eliminate or self-treat against radiation illness. I would suggest to be specific in the product and the scientific rational for that; perhaps links might be of service. (I tried looking for a thread on this topic but did not find any--only some steps folks were taking).
For myself, I'm only using powdered milk, taking iodine, and thinking of cutting down on leafy vegetables.
