It's all easily calculated, the heating effects are very well 
documented. 

If the RF field is below a certain level, it will cause no temperature 
rise. Fortunately we have built in temperature regulation, as well as 
reasonably good thermal conductivity and thermal inertia thanks to 
circulation of a liquid through our bodies.  

RF is non-ionizing radiation. It either creates damage from heat, or 
it doesn't do anything. It does not cause accumulated harmful 
effects over time like ionizing radiation.

This has all be tested and reviewed on human tissue, as well as on 
"rats and mice".

The people I worked with had been evaluating the biological effects 
of EM fields for well over 20 years. Much of the early equipment 
that I re-designed was tube-type gear! One would think hundreds of 
researchers looking hard at one problem for well over 20 years day 
after day would have found some small correlation between 
cancers and non-ionizing radiation.

Being a teacher isn't as safe as it was 50 years ago either. Neither 
is sex.

Most of us realize those three things, aspirin, teaching, and sex 
have nothing to do with EM fields. (With the exception that being 
on the radio too much might affect the last example in a negative 
way.)
