RF exposure can indeed be hazardous. There’s been cases of Cops frying their nuts keeping speed radar guns in their laps - still, that’s up in the GHz range admittedly.

Nevertheless, typical radio freqs can be harmful depending upon the signal strengths and separation distances involved.

It’s interesting that in USSR days their specs for such things were far tighter than ours.

Yes, that was at 10 and 24 GHz, with antenna gains of up to 20 dB (horn antennas). Also, back then, the receivers were so insensitive that the transmitter had to put out 0.1 Watt just to get a readable return signal off a car passing in front of the cop. (My senior design project in college was a doppler radar, and I worked in ELINT/EW/radar for 11 years... I know this stuff.)

But you make a point: radiated emissions is one reason most police no longer use radar, but use lidar (laser radar).
