Family of French physicists, including Antoine César (1788-1878), a pioneer in 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 his discovery of the radioactive properties of uranium.

n.
1. Alexandre Edmond, 1820–91, French physicist (son of Antoine César).
2. Antoine César, 1788–1878, French physicist.

bec·que·rel

(bĕ-krĕl′, bĕk′ə-rĕl′)
A unit used to measure the rate of radioactive decay. Radioactive decay is measured by the rate at which the atoms making up a radioactive substance are transformed into different atoms. One becquerel is equal to one of these atomic transformations per second.
