Disintegration of atomic nuclei resulting in the emission of alpha or beta particles (usually with gamma radiation). Also the exponential decrease in radioactivity of a material as nuclear disintegrations take place and more stable nuclei are formed.
A process in which a particle disappears and in its place different particles appear. The sum of the masses of the produced particles is always less than the mass of the original particle.
This is also called site formation. In most oceans (except the Baltic Sea and a few other places), a shipwreck under water deteriorates rapidly during a first stage. This often takes decades for a wooden ship and about a century for a steel ship (shorter time in shallow water). What remains after that is usually stable for millennia if it remains c...Found on http://www.abc.se/~pa/uwa/glossary.htm

Also known as Radioactive Decay . Radioactive substances undergo radioactive decay, the rate of which is determined by the properties of the radionuclide. As decay proceeds the resulting activity of the parent Nuclide reduces and will eventually disappear. The daughter product may be stable (inactive) or may itself be Radioactive and undergo furthe...Found on http://www.ionactive.co.uk/glossary.html

This is the doctrine (originally from Ebbinghaus, 1885) that forgetting can be caused by the gradual disappearance of a memory trace over time. That is to say, you forget because your engrams spontaneously become fainter and fainter over time, unless you revisit them occasionally to refresh them. [C

the period of an envelope during which a sound's attribute (such as volume) stabilizes after the attack has completed. When the sound attribute reaches the end of it's decay, it has reached the sustain period. The progressive reduction in amplitude of a sound or electrical signal over time. In the context of an ADSR envelope shaper, the Decay phase...Found on http://www.traditionalmusic.co.uk/music%20tech%20glossary/Music%20Tech%20Gl

The decrease in the amount of any radioactive material over time due to the transformation of one nuclide into a different nuclide or into a different energy state of the same nuclide. The decay process results in the emission of nuclear radiation (alpha, beta and gamma) and heat.
