I am not an expert hear but i have hear that the nuclear regulatory commision has as many loopholes as a sweater. If radioactive spoons and dental appliances made it to the public mouths, there may be as much risk or greater of radioactive steel or iron than lead. but the problem remains that lead pipes and paint can kill kids, i am sure that all this lead will come back to haunt us..(atleast i quit pinching split shots with my teeth)
