cu·rie (C, c, Ci),

(kyū'rē),
A unit of measurement of radioactivity, 3.70 ×1010 disintegrations per second; formerly defined as the radioactivity of the amount of radon in equilibrium with 1 g radium; superseded by the S.I. unit, the becquerel (1 disintegration per second).

curie

An obsolete unit of radioactivity (i.e., radioactive decay) equal to 3.7 x 1010 disintegrations/sec of a radioactive nuclide, roughly equivalent to the activity of 1 g of radium; the curie was replaced by the SI-derived unit for radioactivity, the Becquerel (2.70 x 10-11 curies).
