Microcurie

One microcurie is equal to one millionth of a curie (1.0E-6 curies), or 37,000 becquerels.

History: Standard metric prefix applied to the curie.

Current use: Used for measuring small amounts of radioactive tracers and lab samples.

Also written as µCi, uCi, microcuries.

Curie

One curie is approximately the activity of 1 gram of the radium isotope 226Ra, equal to 3.7E+10 becquerels.

History: Named after Pierre and Marie Curie. Originally defined in 1910.

Current use: Still commonly used in the United States and in some clinical settings alongside the becquerel.

Also written as Ci, curies.
