In the process of conducting various experiments in applying currents to different vacuum tubes, he discovered that, despite covering one in a screen to block light, there seemed to be rays penetrating through to react with a barium solution on a screen he’d placed nearby. Created: Jun 11, 2009. Bequerel's technique was to wrap a photographic plate in black paper, lay the uranium-containing mineral on top and expose the set to sunlight, causing the mineral to glow. With her husband, she decided to find out if chemicals other than uranium were radioactive. Physics; Application of the ... Chernobyl. The matter and energy spewing out of a decaying nuclei is what we call radioactivity. It's FREE! The history of nuclear physics as a discipline distinct from atomic physics starts with the discovery of radioactivity by Henri Becquerel in 1896 while investigating phosphorescence in uranium salts. Radioactivity Towards the end of the 19th century, minerals were found that would darken a photographic plate even in the absence of light. Henri Becquerel, a third generation expert on fluorescence and phosphorescence, heard a report (and saw radiographs) of Roentgen’s work at the weekly meeting of the Académie des Sciences on January 20, 1896.
