They do eat RF without passing more than a negligible amount to our
environment. But they also convert the energy from RF energy to radiated
heat which is just as much of an EM wave as the RF wave was. The old
RF wave is destroyed but since the energy in that RF wave cannot be
destroyed, it must be converted. In this case it is converted to
an infrared wavelength.

The way to keep a resistor from radiating heat is to enclose it in
a heat sink in which case the heat sink probably radiates heat as
well as conducts heat.

:-) Why do you think I draw so much flak? :-) I agree with Albert.
