That is interesting. That would explain why the effects vary so much. A threshold response will be complicated. It will vary from individual to another, and also by age and stage of growth. It isn't just the radiation or heat that causes the problem or controls the extent of it; it is the reaction of the body in response. Another example of a threshold response is what happens when you are infected with bacteria. Depending on your state of health, how lucky you are, and various other factors, you may never notice -- or you might be killed. This poor woman in Georgia, Aimee Copeland was exposed to a common waterborne bacteria, Aeromonas hydrophila. This is dangerous but it seldom infects people. When it does infect, the results can be dire. Copeland nearly died, and lost her feet and hands I believe. - Jed
