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.

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.

By the late 1890s, Antoine-Henri Becquerel and Marie and Pierre Curie had discovered the radioactive elements contained within uranium ore, and radium isolated by Marie Curie from uranium-containing ores was thought to hold promise for curing cancer (1).
The discovery of X rays by Rontgen (see 1895) fascinated a French physicist, Antoine-Henri Becquerel (1852-1908), who had been working on fluorescent substances as his father had before him.
