n. Abbr. Ci
A unit of radioactivity, equal to the amount of radioactive decay of an isotope; equal to 3.7 × 1010 disintegrations per second, or 3.7 × 1010 becquerels. In 1975, the curie was replaced by the becquerel as the standard SI unit of radioactivity.
[After Pierre Curie.]

Curie(ˈkjʊərɪ; -riː; French kyri)
1. (Biography) Marie (mari). 1867–1934, French physicist and chemist, born in Poland: discovered with her husband Pierre the radioactivity of thorium, and discovered and isolated radium and polonium. She shared a Nobel prize for physics (1903) with her husband and Henri Becquerel, and was awarded a Nobel prize for chemistry (1911)
2. (Biography) her husband, Pierre (pjɛr). 1859–1906, French physicist and chemist
(Units) a unit of radioactivity that is equal to 3.7 × 1010 disintegrations per second. Symbol: Ci
[C20: named after Pierre Curie]

A unit used to measure the rate of radioactive decay. Radioactive decay is measured by the rate at which the atoms making up a radioactive substance are transformed into different atoms. One curie is equal to 37 billion (3.7 × 1010) of these transformations per second. Many scientists now measure radioactive decay in becquerels rather than curies.
