curie
Decay rate unit
A curie is a unit of radioactivity, measuring the rate of radioactive decay.
One curie equals 37 billion disintegrations per second—roughly the activity of one gram of radium.
Though largely replaced by the becquerel in scientific contexts, the curie remains common in medical and industrial applications: The source contained several millicuries of cesium-137. (Capitalized Curie refers to the scientists Marie or Pierre Curie.)
