  • spontaneous nuclear disintegration of radioactive isotopes; frequency of occurrence of decay is described by half-life
  • a spontaneous nuclear transformation in which corpuscles or gamma radiation are emitted or X-radiation is emitted following orbital capture,or the nucleus undergoes spontaneous nuclear fission
radioaktiivne lagunemine
radioactive decay
Usage examples
  • Increase or decrease in the quantity of nuclear material due to nuclear transformation, e.g. by fission, capture or radioactive decay.
Good to know
  • It is also the decrease with time, by spontaneous nuclear transformation, of the activity of a radioactive substance or a mixture of such substances.
