"Thermal" radiation? What's that?

As commonly used, "thermal radiation" means radiation in the waveband
from about 3 microns to about 20 microns, and represents the peak
wavelength of blackbody radiation for most objects of interest- of
interest to those using the term "thermal radiation".

As a general concept, the electromangtic field carries energy at all
wavelengths.
