Its the thermal energy that the Earth emits. Radiation is essentially another word for heat. There is also solar radiation which is simply the heat from the sun. The Earth actually emits far less thermal energy than what is taken in from by the sun and absorbed into the atmosphere. On the other hand there are planets like Jupiter whose surface temperature is mostly comprised of heat from thermal energy instead of solar radiation.
Almost all types, however mostly infrared, radio waves and visible light.
It absorbs about half that which enters the top of the atmosphere.
The earth absorbs UV rays. It is done by ozone layer.
The Earth shines like a star in certain radio frequencies.
The earth primarily emits infrared radiation due to it's low surface temperature.
Infrared (heat)
IR
Nuclear weapons emit nuclear radiation, with gamma radiation being the most common and dangerous.
Cell phones do emit a type of non-ionizing radiation.
Terrestrial radiation refers to heat emitted from the earth's atmosphere and surface.
Any material will emit blackbody radiation at any temperature. Lithium 6 will never emit ionizing radiation.
A safe reactor don't emit a significant or dangerous quantity of any radiation. But in the core of the reactor all the types of nuclear radiations are emitted.

Yes - many things emit infrared radiation (IR), including toasters.
Cell phones do emit a type of non-ionizing radiation.
Terrestrial radiation refers to heat emitted from the earth's atmosphere and surface.
Any material will emit blackbody radiation at any temperature. Lithium 6 will never emit ionizing radiation.
Black holes does emit radiation, but they cannot be detected from earth. We use gravitational lensing to "see" the black holes.
They do not! Most gases do not emit radiation.
Light waves do not emit radiation, light waves are radiation.
Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.
