There is a big difference between Ionizing and Non-Ionizing Radiation.I always wonder being a pilot and flying these awacs or aewc aircraft and sitting so close to an object shooting so much Electromagnetic radiation. The risk of cancer must be high for them.
Ionizing can rip electrons away and therefor change DNA and cause Cancer. The frequency a radar works in can only heat up matter and the beam is directional. AWACS have been flying for half a century now and the crews and their Children are fine so there can't be any major effect.
