Curie (Ci), radioactive decay

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 was named. In addition to the curie, activity can be measured using an SI derived unit, the becquerel (Bq), which equates to one decay per second.
