Yup.
Microwave ovens operate around 2.45 GHz where water molecules have strong absorption. Of course, microwave ovens are closed metal boxes with standing waves - when working properly, they don't leak radiation. And they often have 1200W of power.

Lots of power for short periods of time, but not so much on average.
(Big AM radio stations are typically 50,000 watts (some used to be 500,000 watts, IIRC).)
In contrast, a cell phone towers typically radiate 5-10 watts, and 1/r^2 is always your friend. ;-)
Things are different at high power - even intense visible light is bad at high enough intensity. And, naturally, there's been lots of research on using high intensity light for countermeasures...
Interesting stuff!
Cheers,
Scott.

Transmit Power
The radar will transmit a waveform with a peak power of 4 kW. Factoring in the antenna gain, the peak ERP (effective radiated power; transmit power multiplied by antenna gain) is 1.26 MW (61 dBW). The radar will operate at a maximum of 10% duty factor, so the maximum average power emitted by the radar is 400 W, with an equivalent maximum average ERP of 126 kW (51 dBW).
