==Key Stage 5==
===Meaning===
In [[radioactivity]], [[activity]] is the number of disintegrations per [[second]] of a [[radioactive]] [[isotope]].
===About Activity===
*[[Measure]]d in [[becquerels]] (Bq), where 1 Bq equals one disintegration per [[second]].
*Indicates the rate at which a sample of [[radioactive]] [[material]] [[Decay (Physics)|decays]].
*Higher [[activity]] means more frequent emissions of [[radiation]].
===Examples===
*Medical tracers have high [[activity]] to ensure they [[emit]] detectable [[radiation]] within a short [[time]].
*[[Radon]] detectors [[measure]] the [[activity]] of [[radon]] gas in homes to assess safety.
