Radiate
Definition:
(v. i.) To emit rays; to be radiant; to shine.
(v. i.) To proceed in direct lines from a point or surface; to issue in rays, as light or heat.
(v. t.) To emit or send out in direct lines from a point or points; as, to radiate heat.
(v. t.) To enlighten; to illuminate; to shed light or brightness on; to irradiate.
(a.) Having rays or parts diverging from a center; radiated; as, a radiate crystal.

(3) Because of the small number of patients reported in the world literature and lack of controlled studies, the treatment of small cell carcinoma of the larynx remains controversial; this retrospective analysis suggests that combination chemotherapy plus radiation offers the best chance for cure.
(4) Breast conserving surgery in patients with small tumors combined with radiation therapy has gained wide popularity due to better cosmetic results without significant changes in survival.
(5) A Monte Carlo simulation was performed to characterize the spatial and energy distribution of bremsstrahlung radiation from beta point sources important to radioimmunotherapy (RIT).
