We radiate in infrared frequencies - many science labs have access to an infrared camera - that is what it is 'seeing'...

We radiate more than just infrared energy. I can think of a few examples:
From 100Hz to 1700Hz we also emit sound waves through use of the human voice, just by breathing, or even when we blow on something.
We can also radiate subsonic frequencies by striking objects, such as with our fists, for example. Or sonic waves by clapping our hands.

Infared is the only thing that we radiate. We don't affect radios so we are not emmiting radio waves. We can't cook pop corn so there are no microwaces. I just know that we don't emit ultra vilot and x-rays. Where alive so we are not emiting gama rays.

The only energy we radiate is infrared (heat). We don't glow or have magnetic or x-ray or gamma radiation.

Infrared light.
