Becquerel's Occurrence Of Natural Radioactivity
Becquerel
In 1896, Becquerel's earlier work was surpassed by his discovery of the occurrence of natural radioactivity. Becquerel decided to investigate whether there was any connection between X-rays and naturally occurring phosphorescence, after his discussion with Henri Poincaré on the radiation which had been recently discovered by Röntgen (X-rays) and which was accompanied by a type of phosphorescence in the vacuum tube. He had inherited from his father a supply of uranium salts, which exhibits phosphorescence upon exposure to light. When the salts were placed near to a photographic plate covered with opaque paper, the plate was found to be fogged. The phenomenon was found to be common to all the uranium salts studied and was concluded
