Activity is the term used to characterise the number
of nuclei which disintegrate in a radioactive substance per unit time
usually measured in Becquerels (Bq); a Bq is 1 disintegration per second.
Replaces the former unit curie, symbol: Ci.
1 Ci is equal to 37,000,000,000 Bq.
Note: "Activity" is a quantitative term whereas
"radioactivity" is a qualitative term used to describe atoms
