curies in Science
curie
  (kyr'ē, ky-rē')   
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.
