The emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei,
The emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei
Radioactive substances, or the radiation emitted by these
radiation: the spontaneous emission of a stream of particles or electromagnetic rays in nuclear decay
(radioactive) exhibiting or caused by radioactivity; "radioactive isotope"; "radioactive decay"; "radioactive fallout"
Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting ionizing particles or radiation. The emission is spontaneous in that the nucleus decays without collision with another particle. ...
Radio-Activity (German: Radio-Aktivität) is the fifth studio album by German electronic band Kraftwerk, released in October 1975. Unlike Kraftwerk's later albums, which featured language-specific lyrics, only the titles differ between the English and German editions. ...
(Radioactive (Heartsdales album)) Radioactive is the 2002 debut album of the Japanese hip-hop group Heartsdales.
(Radioactive (song)) "Radioactive" is a song by English rock band The Firm. It was the first single released from their eponymous début album The Firm, where it was the fifth track. It was written by Paul Rodgers.
Spontaneous emission of ionizing radiation as a consequence of a nuclear reaction, or directly from the breakdown of an unstable nucleus; The radiation so emitted; including gamma rays, alpha particles, neutrons, electrons, positrons, etc
(Radioactive) Exhibiting radioactivity; emitting or relating to the emission of ionizing radiation or particles such as alpha and beta particles, neutrons or gamma rays.
(Radioactive) Capable of emitting radiant energy.
(radioactive) a property of certain elements, or isotopes of an element, whose atomic nuclei are unstable and subject to spontaneous disintegration, thereby giving off ionizing radiation
(radioactive) a term used to describe a substance that emits streams of subatomic particles as it changes to a stable form
(Radioactive) A nuclear substance having a specific activity greater than 70 kiloBequerels per kilogram (kBq/kg). (Radioactif)
(Radioactive) Any material having a measurable specific activity above background. While on the ANL site, materials with a specific activity >= 2nCi/g must be transported by the ANL Special Materials Group. APS must be notified of any shipment of radioactive materials to/from the site.
(Radioactive) Describes substances or objects that emit radiation (Miller 1985).
(Radioactive) Emitting energy waves due to decaying atomic nuclei. Radioactive substances are used in medicine as tracers for diagnosis, and in treatment to kill cancerous cells.
(radioactive) Substance containing an element which decays.
(radioactive) When an atom has to many protons it cannot hold themselves together anymore, when this happens protons emit radiation until they are balanced.
(radioactive) an unstable nuclei which will decay to a different nuclei and emit radioactivity (an alpha, beta, or gamma) in the process.
Materials that emit nuclear radiation, such as uranium.
The release of energy by rare, heavy elements when their nuclei decay into lighter nuclei.
The property possessed by some elements, such as uranium, of giving off alpha, beta, or gamma rays.
Energy emitted as particles or rays during the decay of an unstable isotope to a stable isotope.
The property possessed by some elements (such as uranium) of spontaneously emitting energy in the form of radiation as a result of the decay (or disintegration) of an unstable atom. Radioactivity is also the term used to describe the rate at which radioactive material emits radiation. ...
the process in which atoms undergo internal change with the resultant emission of electromagnetic or particulate radiation.
Property of certain substances to convert without external influence and emit a characteristic radiation. Radioactivity was discovered for uranium by Becquerel in 1896. ...
