 (rā′dē-ŏm′ĭ-tər)
n.
1. A device that measures the intensity of radiant energy, consisting of a partially evacuated glass bulb containing lightweight vertical vanes, each blackened on one side, suspended radially about a central vertical axis to permit their revolution about the axis as a result of incident radiation. Also called light mill.
2. An instrument that detects electromagnetic radiation.

ra·di·om·e·ter

(rā′dē-ŏm′ĭ-tər)
A device used to detect and measure radiation. Radiometers consist of a glass bulb containing a partial vacuum in which four diamond-shaped paddles are mounted on a central axis. Each paddle is black on one side and silvery on the other. When radiation, such as sunlight, strikes them, the black side absorbs radiation and the silvery side reflects it, resulting in a temperature difference between the two sides that causes the paddles to spin. The stronger the radiation, the faster the paddles spin.
