Radiation
In
physics,
radiation is the emission or transmission of
energy in the form of
waves or
particles through space or through a material medium. This includes:
radiation
Noun
1. energy that is radiated or transmitted in the form of rays or waves or particles
(hypernym) energy
(hyponym) ionizing radiation
(derivation) radiate
2. the act of spreading outward from a central source
(hypernym) emission, emanation
(hyponym) bombardment
(derivation) radiate, ray
3. syndrome resulting from exposure to ionizing radiation (e.g., exposure to radioactive chemicals or to nuclear explosions); low doses cause diarrhea and nausea and vomiting and sometimes loss of hair; greater exposure can cause sterility and cataracts and some forms of cancer and other diseases; severe exposure can cause death within hours; "he was suffering from radiation"
(synonym) radiation sickness, radiation syndrome
(hypernym) syndrome
4. the spontaneous emission of a stream of particles or electromagnetic rays in nuclear decay
(synonym) radioactivity
(hypernym) emission
(hyponym) corpuscular radiation, particulate radiation
5. the spread of a group of organisms into new habitats
(hypernym) natural process, natural action, action, activity
(hyponym) adaptive radiation
(derivation) diversify, radiate
6. a radial arrangement of nerve fibers connecting different parts of the brain
(hypernym) neural structure
(derivation) radiate, ray
7. (medicine) the treatment of disease (especially cancer) by exposure to radiation from a radioactive substance
(synonym) radiotherapy, radiation therapy, actinotherapy, irradiation
(hypernym) therapy
(hyponym) phototherapy
(classification) medicine, medical specialty
