The '''curie''' (symbol '''Ci''') is a former unit of
Radioactivity, defined as:
decays per second.
This is roughly the activity of 1 gram of the radium isotope
226Ra, a substance studied by the pioneers of radiology, Marie and Pierre Curie (for whom the unit is named). The curie has since been replaced by an SI derived unit, the
becquerel (Bq), which equates to one decay per second. Therefore:
1 Ci = 37 GBq
1 Bq = 2.7027 x 10
-11 Ci
