Activity is the term used to characterise the number of nuclei which disintegrate in a radioactive substance per unit time usually measured in Becquerels (BqSymbol for becquerel, the name of the unit for activity.); a BqSymbol for becquerel, the name of the unit for activity. is 1 disintegration per second. Replaces the former unit curieName for the former unit of activity.
