Becquerel
Unit of activity of a radionuclide named after Henri Becquerel who first discovered radioactivity. Symbol: Bq. The activity is equal to 1 becquerel if 1 nucleus decays per second in the present quantity of a radionuclide. The unit replaces the former unit curie.

BECQUEREL
SI unit of activity or nuclear transition rate equal to one per second (symbol 1 Bq). Caveat illustration: The activity of 1 nanomole of 40K (half life = 1.25 X 109 years) would be approximately 10.5 Bq but the gamma activity of that same nanomole would be only 1.13 Bq because only 10.7% of 40K's decays involve a gamma branch. To avoid ambiguity, the latter should be referred to as 1.13 gamma Bq.

Becquerel
The becquerel (symbol Bq) is the SI derived unit of radioactivity. 1 Bq is 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 becquerel is named for Henri Becquerel, who shared a Nobel Prize with Pierre and Marie Curie for their work in discovering radioactivity.

Becquerel (eenheid)
De becquerel is de SI-eenheid voor radioactiviteit, wordt aangegeven met Bq en beschrijft het aantal atoomkernen dat per seconde radioactief vervalt. De becquerel vervangt de oudere niet-SI-eenheid curie en is genoemd naar Antoine Henri Becquerel.

Becquerel
In the International System of Units, the derived unit of radioactive activity; the activity of a quantity of radioactive material in which one nucleus decays per second.
