Because the radiation effects accumulate over time. Why add more to it??![]()
Even the sun gives you more radiation than a cell phone. And electromagnetic radiation is a different story than the Japanese nuclear reactor. The isotopes being sent over here now have half lives of hundreds or thousands of years. Depending on where you live you are getting tens or hundreds of miliRems per year.
The Japanese reactors are sending out thousands of times the radiation as Chernobyl did over twenty years. And Chernobyl killed approximately one million souls. You would be safer eating the cell phone than living on the US west coast today.
