(a.) Especially, emitting or darting rays of light or heat; issuing in beams or rays; beaming with brightness; emitting a vivid light or splendor; as, the radiant sun.
(a.) Beaming with vivacity and happiness; as, a radiant face.
(a.) Giving off rays; -- said of a bearing; as, the sun radiant; a crown radiant.
(a.) Having a raylike appearance, as the large marginal flowers of certain umbelliferous plants; -- said also of the cluster which has such marginal flowers.
(n.) The luminous point or object from which light emanates; also, a body radiating light brightly.

Example Sentences:
(1) The thermoregulatory effects of isothermogenic doses of isoproterenol (Iso) and a novel beta-agonist (BRL 35135) were tested in rats at 22 degrees C and in rats trained to bar press for radiant heat at -8 degrees C.
