Speaking about radioactive fallout, the late President John F. Kennedy said, "Even then, the number of children and grandchildren with cancer in their bones, with leukemia in their blood, or with poison in their lungs might seem statistically small to some, in comparison with natural health hazards. But this is not a natural health hazard and it is not a statistical issue. The loss of even one human life, or the malformation of even one baby who may be born long after we are gone, should be of concern to us all. Our children and grandchildren are not merely statistics toward which we can be indifferent."
