curie

 (Ci) [ku´re]
a unit of radioactivity, defined as the quantity of any radioactive nuclide in which the number of disintegrations per second is 3.700 × 1010.

Curie

Marie (1867-193) and Pierre (1859-1906), French chemists and physicists and Nobel laureates (wife and husband). See: curium.

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per second; formerly defined as the radioactivity of the amount of radon in equilibrium with 1 g radium; superseded by the S.I. unit, the becquerel (1 disintegration per second).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 (Ci)

[kyoo͡r′ē]
Etymology: Marie Skladowska Curie, Polish-born chemist and physicist, 1867-1934; Pierre Curie, French chemist and physicist, 1859-1906; both Nobel laureates
a unit of radioactivity used before adoption of the becquerel (Bq) as the SI unit. It is equal to 3.70 × 1010 Bq.

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).

A unit of measurement of radioactivity, 3.70 × 1010 disintegrations per second; superseded by the S.I. unit, the becquerel (1 disintegration per second).

(C) (kyūr'ē)
A unit of measurement of radioactivity superseded by the S.I. unit, the becquerel (1 disintegration per second).

curie (kyŏŏ´rē),

a measurement of radioactivity produced by the disintegration of unstable elements. The curie is that quantity of a radioactive nuclide in which the number of disintegrations per second is 3.700 times 1010. Because the curie is a relatively large unit, the millicurie (0.00 curie) and the microcurie (one-millionth of a curie) are more often used. The curie is based on the number of nuclear disintegrations and not on the number or amount of radiations emitted.

curie

a non-SI unit of radioactivity, defined as the quantity of any radioactive nuclide in which the number of disintegrations per second is 3.7 × 1010; abbreviated Ci. Now replaced by the becquerel.

At 35, Pierre Curie was eight years older than Marie and had already done work that should have been well known in scientific circles: His study of crystals had led him to postulate important laws of symmetry, and he had been conducting experiments in magnetism that would produce enduring laws.
The rain and the traffic were heavy that day as Pierre Curie approached rue Dauphine, just a block from the Institut library along the Seine where he planned to do some reading.
At some point in the summer of 1910, mutual sympathy between Marie Curie and Langevin turned into passion.
But in the meantime, Marie Curie was placed in greater jeopardy by the decision she made, with the encouragement of colleagues, to apply for membership in the AcademyofScience.
In October of 1911 Marie Curie attended the historic Solvay Conference in Brussels, along with 20 other illustrious scientists, including Albert Einstein, Max Planck, Ernest Rutherford, Jean Perrin, and, of course, Paul Langevin.
Someone, probably at the behest of Langevin, broke into Marie Curie and Paul Langevin's pieda-terre and stole intimate letters, and when Paul Langevin's wife instituted legal action, she threatened to use the letters as part of her case in court.

On July 4, 1934, at the age of 67, Curie died of aplastic anemia, a blood disease that often results from radiation exposure.
Curie is said to have become an agnostic as a teenager and was described variously throughout her life as a rationalist, atheist, and freethinker.
