Microwave ovens have been in common use since the 1970's. Cell phones since the 1980's. If there was a problem with exposure to RF at these power levels then we would expect to see a statistically significant increase in, e.g. certain cancers as a result. Of course using the entire population of the Western world as a (not very controlled) experiment is probably not the most ethical way to gather this data, but it is useful data nonetheless. Paul --
