radiation actinotherapy
irradiation | (medicine) the treatment of disease (especially cancer) by exposure to a radioactive substance |
| radiation | the act of spreading outward from a central source |
| radiation pyrometer | a pyrometer for estimating the temperature of distant sources of heat, radiation is focussed on a thermojunction connected in circuit with a galvanometer |
| acoustic radiation pressure | (acoustics) the pressure exerted on a surface normal to the direction of propagation of a sound wave |
optic radiation
radiatio optica | a nerve pathway from the lateral geniculate body to the visual cortex |
| radiation | a radial arrangement of nerve fibers connecting different parts of the brain |
| Planck's radiation law | (physics) an equation that expresses the distribution of energy in the radiated spectrum of an ideal black body |
radiation pattern
radiation diagram
pattern | graphical representation (in polar or Cartesian coordinates) of the spatial distribution of radiation from an antenna as a function of angle |
| background radiation | radiation coming from sources other than those being observed |
| radiation | the spread of a group of organisms into new habitats |
| adaptive radiation | the development of many different forms from an originally homogeneous group of organisms as they fill different ecological niches |
actinic radiation
actinic ray | electromagnetic radiation that can produce photochemical reactions |
alpha radiation
alpha ray | the radiation of alpha particles during radioactive decay |

visible light
visible radiation | (physics) electromagnetic radiation that can produce a visual sensation, the light was filtered through a soft glass window |
| radiation field | a field that represents the energy lost from the radiator to space |
| neutron radiation | radiation of neutrons (as by a neutron bomb) |
radiation pressure
corpuscularadiation pressure | the minute pressure exerted on a surface normal to the direction of propagation of a wave |
| radiation | energy that is radiated or transmitted in the form of rays or waves or particles |

radiation
radioactivity | the spontaneous emission of a stream of particles or electromagnetic rays in nuclear decay |
radiation sickness
radiation syndrome
radiation | 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 |
sterilized
