This led the Curies to isolate the cause of this radioactivity in two elements, one which they called “polonium” after Marie’s native land, and the other which they called “radium” for its power to irradiate. In consequence of her part in the discovery of what she called “radioactivity” she was awarded the Nobel Prize for Physics with her husband and Henri Becquerel in 1903.
Becquerel (1852-1908), a French engineer and physicist, had begun work on the phosphorescence of …
