Radiation
Definition:
(n.) The act of radiating, or the state of being radiated; emission and diffusion of rays of light; beamy brightness.
(n.) The shooting forth of anything from a point or surface, like the diverging rays of light; as, the radiation of heat.
Example Sentences:

(2) Sixteen patients were operated on for lumbar pain and pain radiating into the sciatic nerve distribution.
(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).
(6) While both inhibitors caused thermosensitization, they did not affect the time scale for the development of thermotolerance at 42 degrees C or after acute heating at 45 degrees C.
