"unit of radioactivity," 1910, named for Pierre Curie (1859-1906) or his wife, Marie (1867-1934), discoverers of radium.
Joliot-Curie Jo·liot-Cu·rie (zhô-lyō'kyur'ē, -kyu-rē', -kü-), Irène. 1897-1956.
French physicist. She shared a 1935 Nobel Prize with her husband, Frédéric Joliot-Curie (1900-1958), for synthesizing new radioactive elements.
curie cu·rie (kyur'ē, kyu-rē')
A unit of radioactivity, equal to the amount of a radioactive isotope that decays at the rate of 3.7 × 1010 disintegrations per second.
Curie Cu·rie (kyur'ē, kyu-rē', kü-), Marie. Originally Manja Skłodowska.. 1867-1934.
Polish-born French chemist. She shared a 1903 Nobel Prize with her husband, Pierre Curie (1859-1906), and Henri Becquerel (1852-1908) for fundamental research on radioactivity. In 1911 she won a second Nobel Prize for her discovery and study of the elements radium and polonium.
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.
