I have a question I think some of us are really asking at this time. What are we really looking at if the Japan Nuclear reactors start spewing radiation? What if it reaches the US? How do we prepare for such an event? I have extra food and water stored. But, my question is what kind of sickness does radiation cause? I heard some people say to take Potassium Iodine (hopefully I spelled it right). I would really like to know.
