Infrared refers to invisible light just off of the red end of the visual light spectrum. Radiation refers to the wavelenght. The shorter the wave the more energy. In a nutshell infrared radiation is basically heat.

Infrared (IR) radiation is electromagnetic radiation of a wavelength longer than that of visible light, but shorter than that of microwaves. The name means "below red" (from the Latin infra, "below"), red being the color of visible light with the longest wavelength. Infrared radiation has wavelengths between about 750 nm and 1 mm, spanning five orders of magnitude.
