The becquerel (symbol Bq) is the SI derived unit of radioactivity, defined as the activity of a quantity of radioactive material in which one nucleus decays per second. It is therefore equivalent to s-1. The older unit of radioactivity was the curie (Ci). 1 Bq = 2.7×10-11 Ci, i.e. 27 picocuries.
It was named after Henri Becquerel, who shared a Nobel Prize with Marie Curie for their work in discovering radioactivity.
In a fixed mass of radioactive material, the number of becquerels changes with time. In some circumstances, amounts of radioactive material are given after adjustment for some period of time. For example, one might quote a ten-day adjusted figure, that is, the amount of radioactivity that will still be present after ten days. This deemphasizes short-lived isotopes.
