When the nucleus is unstable, one of the ways to reach stability is to emit electromagnetic radiation in the form of gamma rays.
Beta radiation does not have a helium nucleus.Alpha radiation, however, does have a helium nucleus.
Energy/radiation
The source of cosmic background radiation filled the entire universe.
Gamma radiation
The sun is the source of radiation for both the earth's atmosphere and the greenhouse effect.
Electromagnetic radiation bands are known as the EMR spectrum.
it's composition is high-energy eletromagnetic radiation
Electromagnetic radiation
Beta radiation does not have a helium nucleus.Alpha radiation, however, does have a helium nucleus.
No, The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation.[1] The "electromagnetic spectrum" of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object.
Infra red radiation is part of the Eletromagnetic Spectrum, it includes all types of radiation including: Radio waves, microwaves, Infra red radiation, visible light, ultraviolet, x- rays and gamma rays.Infra red radiation risks: it can damage your cornea.
It depends what you are talking about... Electromagnetic field Electromagnetic force Electromagnetic radiation Electromagnetic spectrum Electromagnetic therapy Electromagnetic waves ...they each have different meanings.
Radiation
the fundemental source of electromagnetic radiation is an ionic explosion
Nucleus
Cosmic radiation External terrestrial and internal radiation
radiation is emmited
