(radioactive decay)
31Decay correct — is a method of adjusting the measurements of radioactive decay obtained at two different time points so that they may be used as a single data set. If a chemical compound is tagged with a radioactive isotope then the amount of radiation released… …
32Radioactive (disambiguation) — Radioactive describes something undergoing radioactive decay, the process by which an unstable atom emits radiationOtherwise the terms radioactive and radioactivity may refer to:Radioactive materials*Naturally occurring radioactive material… …
33decay heat — noun (nuclear eng) The heat produced by the radioactive decay of fission products formed in a nuclear reactor • • • Main Entry: ↑decay …
34Radioactive waste — 2007 ISO radioactivity danger logo, designed in part for long term radioactive waste depositories which might survive into a far future time in which all knowledge of the meaning of present common radiation danger symbols and signs has been lost… …
35Decay chain — In nuclear science, the decay chain refers to the radioactive decay of different discrete radioactive decay products as a chained series of transformations. Most radioactive elements do not decay directly to a stable state, but rather undergo a… …
36Decay product — The decay chain from lead 212 down to lead 208, showing the intermediate decay products. In nuclear physics, a decay product (also known as a daughter product, daughter isotope or daughter nuclide) is the remaining nuclide left over from… …
37Decay heat — RTG pellet glowing red because of the heat generated by the radioactive decay of plutonium 238 dioxide, after a thermal isolation test. Decay heat is the heat released as a result of radioactive decay. This is when the radiation interacts with… …
38Decay energy — Nuclear physics Radioactive decay Nuclear fission Nuclear fusion Classical decays …
39radioactive series — Physics, Chem. a succession of elements initiated in the radioactive decay of a parent, as thorium or uranium, each of which decays into the next until a stable element, usually lead, is produced. Also called decay series. [1920 25] * * * Any of… …
40decay constant — Physics. the reciprocal of the decay time. Also called decay rate, disintegration constant. [1930 35] * * * ▪ nuclear physics proportionality between the size of a population of radioactive atoms and the rate at which the population… …
