becquerel

 (Bq) [bek-ĕ-rel´]
the SI unit of radioactivity, defined as the quantity of a radionuclide that undergoes one decay per second; one curie equals 3.7 × 1010 becquerels.

becquerel

/bec·que·rel/ (bek″ĕ-rel´) a unit of radioactivity, defined as the quantity of a radionuclide that undergoes one decay per second (s−1). One curie equals 3.7 × 1010 becquerels. Abbreviated Bq.

becquerel (Bq)

[bekrel′, bek′ərel′]
Etymology: Antoine H. Becquerel, French physicist, 1852-1908
the SI unit of radioactivity, equal to one radioactive decay per second. See also curie.

Becquerel

The International System (SI) unit for measuring radioactivity based on radioactive decay, equal to 1 disintegration (nuclear transition)/sec. Named after Antoine-Henri Becquerel, French Nobel Laureate, who discoverered of radioactivity. 

1 Bq = 3.70 x 1010 Ci (Curie, which it supersedes)

Becquerel

A unit of the strength of radioactivity from a particular source. A Becquerel is defined as one nuclear disintegration per second.

becquerel - the SI unit of measurement of radioactivity.
Becquerel rays - obsolete term for radiation given off by uranium and other radioactive substances.

becquerel

the SI unit of radioactivity, defined as the quantity of a radionuclide that undergoes one decay per second (s−1). One becquerel equals 3.7 ×10−11 Ci. Abbreviated Bq. Supersedes the curie.
