The same people are convinced that there is another motivation behind the FCC RF safety regulations, other than protection of the public. It is to these people that I point out the example of cigarette smoking. I don't know anyone who does not believe that smoking is bad for human health. However, we all know, or have heard of, people in their 90s who have smoked every day since they were in their 20s and are still in perfect health. No one disputes that these people exist, but no one disputes that there is a direct correlation between smoking and lung cancer, as well as very strong associations to many other diseases.
Biological variation is one of the great mysteries of humanity.
RF safety standards are based on the best scientific information available. Laboratory studies with animals and epidemiological studies with humans have identified RF exposure levels that have clear ill effects. The more extreme forms include death of cells due to excessive heating. Lesser exposures have been identified as causing behavioral changes. The safety standards take all of this into account and set exposure limits that are intended to prevent any of these effects from occurring in the population.
