Bec·que·rel (b -krl , bk  -rl) Family of French physicists, including Antoine César (1788-1878), one of the first investigators of electrochemistry; his son Alexandre Edmond (1820-1891), noted for his research on phosphorescence and spectroscopy; and his grandson Antoine Henri (1852-1908), who shared a 1903 Nobel Prize for fundamental work in nuclear physics. |
| bec·que·rel (b-krl, bk-rl) n. Abbr. Bq The International System unit of radioactivity, equal to one nuclear decay or other nuclear transformation per second. [After Antoine Henri Becquerel.] |
becquerel [beck-a-rell]
Noun
the SI unit of activity of a radioactive source [after A H Becquerel, physicist]
| becquerel (b-krl, bk-rl) The SI derived unit used to measure the rate of radioactive decay. When the nucleus of an atom emits nucleons (protons and/or neutrons) and is thereby transformed into a different nucleus, decay has occurred. A decay rate of one becquerel for a given quantity means there is one such atomic transformation per second. |
| Becquerel Family of French physicists, including Antoine César (1788-1878), one of the founders of the science of electrochemistry; his son Alexandre Edmond (1820-1891), noted for his research on phosphorescence, magnetism, electricity, and optics; and his grandson Antoine Henri (1852-1908), who discovered spontaneous radioactivity in uranium. Antoine Henri Becquerel's work led to the discovery of radium by Marie and Pierre Curie, with whom he shared the 1903 Nobel Prize for physics. |
