The spontaneous radioactive transformation of one nuclide into a different nuclide or into a different energy state of the same nuclide. Every decay process has a definite half-life.
To break down into component parts: to rot.
Exotic particles produced at accelerators are often very short-lived, and can transform into lighter, less exotic products, such as electrons and photons. This process of transformation is known as decay.
The process whereby radioactive particles undergo a change from one form, or isotope, to another, releasing radioactive particles and/or energy.
Radioactive sources lose their energy over time. With a half-life of 60 days, a radioactive source would have lost half its energy in 60 days. Physicists and physicians use a decay table for determining the activity level on a given day. The half-life for Iodine is approximately 60 days, making it “half active†in 60 days and virtually inactive in 9-12 months.
Disintegration of a wood substance due to action of wood destroying fungi.
The spontaneous transformation of a nuclide into one or more other nuclides either by emitting one or more subatomic particles or gamma rays from its nucleus or by nuclear fission.
radioactive the decrease in the amount of any radioactive isotope with the passage of time due to the spontaneous emission of radiation from the atomic nuclei (either alpha or beta particles, often accompanied by gamma radiation), and consequent transformation to a different chemical form.

The spontaneous reduction of an effect with time.(1) The disintegration process of the nucleus of an unstable isotope by the spontaneous emission of charged particles and/or photons.(2) The equilibration process of heat transfer after the disturbance of thermal equilibrium.(3) The progressive reduction in amplitude of a transient signal due to damping or energy absorption.
Radioactive emission takes place at the instant that an atom disintegrates. As the number of radioactive atoms is reduced by this disintegration, the rate of radioactive emission is said to decay or lessen with time.
The decrease in activity of any radioactive material with the passage of time due to spontaneous emission from the atomic nuclei of either alpha or beta particles, sometimes accompanied by gamma radiation. See; Half Life, Radioactivity.
The disintegration of the nucleus of an unstable atom by spontaneous fission, by the spontaneous emission of an alpha particle or beta particle, isomeric transitions, or by electron capture.
The process whereby unstable excited atoms naturally shed a photon and return to their ground energy state. That photon in turn will strike another excited atom and cause it to shed a photon in the same direction as the first photon. The process repeats in a cascade to create a laser beam.
the organic phenomenon of rotting
the spontaneous disintegration of a radioactive substance along with the emission of ionizing radiation
lose a stored charge, magnetic flux, or current; "the particles disintegrated during the nuclear fission process"
To rot; the breakdown of disintegration of matter.
Change of an element into a different element, usually with some other particle(s) and energy emitted.
The change of one radioactive nuclide into a different nuclide by the spontaneous emission of alpha, beta, or gamma rays, or by electron capture. The end product is a less energetic, more stable nucleus. Each decay process has a definite half-life.
The rate at which a spectrum analyzer display changes. A fast decay rate reacts faster to changes in music. A slower rate is better for doing response analysis. Also, the smell of rotting leaves in a Northwest forest.
Gradual disintegration of radioactive material over time.
Radioactive decay describes the process where an energetically unstable atom transforms itself to a more energetically favorable, or stable, state. The unstable atom can emit ionizing radiation in order to become more stable. This atom is said to be "radioactive" and the process of change is called "(radioactive) decay."
The action of air drag upon an artificial satellite causing it to spiral back into the atmosphere, eventually to disintegrate or burn up.
The decomposition of wood substance by fungi (other terms: rot, dote)
Disintegration of wood fibers by action due to insects, wood-decaying fungus, or water damage.
To lose strength. To rot or decompose.
Spontaneous disintegration of the nucleus of an unstable atom, resulting in the emission of particles and energy.
A process in which a particle disappears and in its place two or more different particles appear. The sum of the masses of the produced particles is always less than the mass of the original particle.
The decomposition of wood by fungi. Advanced Decay - The older stage of decay in which destruction is readily recognized by soft, pitted, or crumbly areas. Decided discoloration or bleaching of the rotted wood is often apparent. Incipient Decay - The early stage of decay that has not proceeded far enough to soften or otherwise perceptibly impair the hardness of the wood. It is usually accompanied by a slight discoloration or bleaching of the wood. DELAMINATION - The separation of layers in a laminate, through failure within the adhesive, or at the bond between adhesive and laminate.
In time-domain electromagnetic theory, the weakening over time of the eddy currents in the ground, and hence the secondary field after the primary field electromagnetic pulse is turned off. In gamma-ray spectrometry, the radioactive breakdown of an element, generally potassium, uranium, thorium, or one of their daughter products.
to rot, break down or decompose.
Spontaneous disintegration of a radionuclide accompanied by the emission of ionizing radiation in the form of alpha or beta.
Literally: breakdown. Used to describe how radioactive isotopes ( radionuclides) gradually break down to form stable isotopes. During decay smaller, particles are emitted (alpha and/or beta particles) as well as pure radiation, gamma rays. Some radioactive isotopes decay very fast (seconds to minutes) others extremely slowly (years to millennia).
To lose matter over time. Unstable isotopes lose matter due to radiation. DNA - The substance that provides instructions for building living things.
The disintegration of an unstable nucleus with the emission of radiation. Radioactivity
radioactive emission which takes place the instant that the nucleus of an unstable releases radiation in an attempt to become more stable.
In nuclear physics, the process of disintegration of an unstable radioisotope by the spontaneous emission of ged particles or photons.
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.
The process of spontaneous transformation of a radionuclide. The decrease in the activity of a radioactive substance.
Disintegration of wood or other substance through the action of fungi.
