They do not! Most gases do not emit radiation.
nuclear reactions
Any material will emit blackbody radiation at any temperature. Lithium 6 will never emit ionizing 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.
Warm bodies emit infrared radiation.
Nuclear weapons emit nuclear radiation, with gamma radiation being the most common and dangerous.
They emit infrared radiation
Black holes are believed to emit something called Hawking radiation.
No, they do not. Because of the technology, LCD televisions emit far less energy than standard televisions and do not emit radiation.
Radioactive elements such as radium or uranium emit radiation. There are three types of "radiation"; alpha particles (which are solitary electrons), beta particles (helium nuclei, consisting of two protons and two neutrons) and "gamma radiation", which is high-energy electromagnetic energy similar to light or X-rays.
The atoms become some other type of atom. In the process, they emit some radiation, which contains energy. The radiation they emit typically include one or more of the following: alpha particles (helium-4 nuclei), beta particles (electrons or positrons), gamma rays, and neutrinos.
Well, yes. They couldn't work if they didn't emit electromagnetic radiation in the form of radio waves.
