Radioactive Decay: Spontaneous change in an atom by emission of of charged particles and/or gamma rays; also known as radioactive disintegration and radioactivity.
Radioactive Substances: Substances that emit ionizing radiation.
Radioactive Decay - The spontaneous breakdown of certain kinds of atomic nuclei into one or more nuclei of different elements, involving the release of energy and subatomic particles. [Crutzen, Paul J. and Graedel, T.E.
radioactive decay: Radioactive decay is the spontaneous transformation of one nuclide into another nuclide or different energy state; in the transformation process, radiation is emitted.
Radioactive decay describes the process where by Radioactive substances decay spontaneously with the release of energy in the form of Electromagnetic Radiation or particulate radiation. The rate of radioactive decay will depend on the Half-Life .
Beta Particle: A charged particle emitted from a nucleus during radioactive decay, with a mass equal to 1/1837 that of a proton. A negatively charged beta particle is identical to an electron.
Short-lived radioactive decay products of radon that decay into longer-lived lead isotopes. The daughter isotopes can attach themselves to airborne dust and other particles and, if inhaled, damage the lining of the lung.
Radon: A colorless, naturally occurring gas formed by radioactive decay of radium atoms. Radon accumulating in basements and other areas of buildings without proper ventilation has been identified as a leading cause of lung cancer.
High speed electrons, which are emitted from the nuclei of radioactive atoms during radioactive decay, as a result of the transformation of a neutron into a proton.
Most of the chemicals undergo chemical, biological or radioactive decay in the environment. Substances which do not undergo these types of reaction are called conservative substances.
Constituent(s) of Concern ...
decay heat The heat generated by the radioactive decay of fission products.
Radon: A colorless, naturally occurring, radioactive, inert gaseous element formed by radioactive decay of radium atoms in soil or rocks.
geothermal energy: electricity produced by using geothermal heat (that is, heat found underground) to create steam to drive turbines. Geothermal heat originated in various ways, including the original formation of the planet, or radioactive decay ...
Fossil fuels are devoid of 14C because of the radioactive decay of 14C to 14N during long underground storage and are depleted in 13C because of isotopic fractionation eons ago during photosynthesis by the plants that were the precursors of the ...
