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

(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
corpuscular radiation
particulate radiation
a stream of atomic or subatomic particles that may be charged positively (e.g. alpha particles) or negatively (e.g. beta particles) or not at all (e.g. neutrons)

ultraviolet spectrum the spectrum of ultraviolet radiation
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
