curies
Decay rate units
Curies is the plural of curie, a unit measuring radioactivity—specifically, the rate of radioactive decay.
Named after Marie and Pierre Curie, who pioneered research on radioactivity.
One curie equals 37 billion atomic disintegrations per second: The sample measured 0.5 curies.
Though largely replaced by the becquerel in scientific contexts, curies remain common in medical and industrial settings.
