The decay of No nuclides to give N nuclides after time t is given by N = Noexp(-[gamma]t), where [gamma] is called the decay constant or the disintegration constant. The reciprocal of the decay constant is the mean life. 6, record 2, English, - radioactive%20decay
Record number: 2, Textual support number: 1 OBS
Decay is associated with the loss of the radioactive isotope and the formation of another isotope of the same element but of lower mass, or the formation of one or more different elements. The rate of decay is proportional to the amount of the radioactive isotope present in the sample and is characterized in terms of its half-life. The half-life is the time taken for the radioactivity to decay to 50% of its original activity. 7, record 2, English, - radioactive%20decay

Le noyau de certains atomes est par nature instable et susceptible de subir une modification interne spontanée qui donne lieu à l'émission d'énergie : il s'agit de la désintégration radioactive. Les atomes instables s'appellent les «radionucléides». Chacun des radionucléides connus [...] a un rythme de désintégration bien caractéristique exprimé en «période radioactive», le temps nécessaire à la désintégration de la moitié des atomes radioactifs présents à l'origine. 3, record 2, French, - d%C3%A9sint%C3%A9gration%20radioactive

Les radio-isotopes les plus fréquemment utilisés en recherche biologique sont le tritium3H et le14C, leur désintégration s'accompagne d'une émission de particules bêta(-). D'autres émetteurs bêta(-) ont un intérêt biologique :35S,45Ca,36Cl,32P, leur énergie varie entre 0 et 18 kev [kiloélectronvolts] pour le3H et de 0 à 155 kev pour le14C. 5, record 2, French, - d%C3%A9sint%C3%A9gration%20radioactive
