Curie (Ci)
« on: Nov 23, 2005, 11:56 »
The curie is a unit used to measure a radioactivity. One curie is the amount of radioactivity in one gram of the element first discovered by Madame Curie, Radium. It is also the quantity of a radioactive material that will have 37,000,000,000 transformations in one second. Often radioactivity is expressed in smaller units like: thousandths (mCi), one millionths (uCi) or even billionths (nCi) of a curie. The relationship between Becquerel and curie is: 3.7 x 1010 Bq in one curie.

The basic unit used to describe the intensity of radioactivity in a sample of material. The curie is equal to 37 billion (3.7 x 1010) disintegrations per second, which is approximately the activity of 1 gram of radium. A curie is also a quantity of any radionuclide that decays at a rate of 37 billion disintegrations per second. It is named for Marie and Pierre Curie, who discovered radium in 1898.

A measure of radioactivity based on the observed decay rate of approximately one gram of radium.  The Curie was named in honor of Pierre and Marie Curie, pioneers in the study of radiation.

One curie of radioactive material will have 37 billion atomic transformations (disintegrations) in one second.

3.7e10 which is shorthand for 3.7x1010
