The original Radarange (microwave) cooked at either 500 or 800 watts, the upper number of which is the upper range in the study (10W/kg), where a human might weigh 80kg, = 800 watts.

My late uncle was in the US Army in Desert Storm. During that period, it was always hot, even at night, and the most comfortable place to sleep at night was on top of the humvee's hood.

But one night the radar got left on overnight, and he literally got cooked from the inside out (when it's 100 degrees outside, it's hard to pick up on that sort of thing).

He had health problems for the remainder of his life and died young (never found out how, but cancer would be my first guess). I really liked him.
