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.
Doesn't the aluminium skin of the aircraft block most of the radiation from the antenna? Only very high frequency radio waves like UV, X and gama can penatrate the aluminium skin and cause cancer, not the radar's.
Fighter pilot sits under the canopy which always let in radiation from the sun. The higher up they go the stronger the radiation. The sun radiation is UV which causes cancer.
The rule of thumb is the higher the frequency, and the shorter the wavelength, of the E.M. Wave the more ionizing/energetic it will be i.e. causing more damage to whatever comes its way e.g. body tissues, even electronics if it's strong enough.
The rule goes vice versa when it comes to the penetrative power. Long E.M. Waves like radio waves (UV, X-ray, and gamma rays are NOT considered radio waves) can go through practically everything with comparatively little attenuation and no ionizing effect and are quite harmless to humans.
