Please don't hijack someone else's thread.

 

Not very harmfull. Look at all the idiots in the world who are potentially cooking their brains and eyeballs with a GHz transmitter located a few cm away.

 

This sums it up quite good http://www.cancer.org/cancer/cancer...dicaltreatments/radiation-exposure-and-cancer

 

Depends of both the frequency and the power level. There are exposure limits that all operators of transmitters need to be aware of. Check out the link for info.

Name the frequency. Sub-gigahertz, generally not. More, water starts absorbing and tissue starts heating.
