(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.

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. BRL 35135 produced hyperthermia at 22 degrees C and reduced operant responding for heat at -8 degrees C, whereas Iso reduced body temperature and increased operant responding.
