It's only staring into the waveguide that gives you cataracts on radar. Though certainly you'd not want to stand on a step ladder in front of the dish if the motor drive failed and the magnetron kept going.
Microwave ovens are super safe if the door works.
Biggest risk with travelling wave tube based microwave links was the frightening power supply in the shack under the mast.
Some secondary radar doesn't emit ANY signals, it's receiving only the reflections of pulses from main radar elsewhere.
Also the inverse square law suggests setting grass on fire is apocryphal. The most powerful radar won't even warm the grass 5 meters away. It's also a focused beam, so there is almost no signal below the dish.
I qualified originally as an RF Communications engineer before changing to computer programming.
