The
becquerel(symbolBq') is the SI derived unit of radioactivity in the
International System of Units (SI), and equal to one disintegration or nuclear transformation per
second. It is therefore equivalent to
s-1. The older unit of radioactivity was the curie (Ci), defined as 3.7×10
10 becquerels or 37 GBq.
History
The becquerel is named after Antoine Henri Becquerel, the French physicist credited with the discovery of radioactivity.
