    Extractions: Reversibility Were it not for several unexpected discoveries, we still might not be aware of high energy radiation which is nearly always unnoticed by our senses. As the 19th Century drew to a close, many investigators were studying the behavior of electric sparks passing through glass tubes from which air had been removed. It had been found that some substances would glow when struck by such sparks. November 8, 1895 (1845-1923) noticed that outside but near such apparatus ( up to 2 m away unknown radiation which he therefore called X-rays. read more detail ), identified them to be a form of electromagnetic radiation, then mailed his findings to other scientists on New Year's Day 1896.

Becquerel noted that the exposure could not be attributed to the luminous radiation emitted by the very brief phosphorescence. Becquerel was cautious to avoid claiming that this radiation was actually X-rays. It was clear that

Investigating the work of Wilhelm Conrad Röntgen , Becquerel wrapped a fluorescent mineral, potassium uranyl sulfate , in photographic plates and black material in preparation for an experiment requiring bright sunlight. However, prior to actually performing the experiment, Becquerel found that the photographic plates were fully exposed. This discovery led Becquerel to investigate the spontaneous emission of nuclear radiation. In

    Extractions: Contribution to the Development of the Atomic Concept Becquerel discovered the radioactivity of uranium by accident. Searching for a connection between X rays (recently discovered by Roentgen) and phosphorescence, he placed a covered photographic plate next to a phosphorescent uranium salt. The plate became exposed even though it had an opaque cover and therefore was not subject to any light. Becquerel established that some of the radiation emitted by the uranium was deflected by a magnet, unlike X rays; also, the radiation was emitted by all uranium salts, whether phosphorescent or not. His discoveries led to the receipt of the Nobel Prize in physics for 1903 (shared with Marie and Pierre Curie).

V roce 1872 zaèal Becquerel studovat paøížskou polytechniku. Pozdìji se specializoval na stavbu silnic a mostù. Jeho hlavním zájmem zùstala fyzika. V roce 1895 se Becquerel stal profesorem fyziky na polytechnice v Paøíži. Zde uèinil svùj nejvýznamnìjší objev. Roku 1896 Becquerel objevil pøirozenou radioaktivitu.

Henri was very interested in Roentgen’s work and wondered if fluorescing minerals would produce the same results. He wrapped a fluorescent mineral, potassium uranyl sulfate, in photographic plates and black material and put them in a drawer because it was cloudy. Instead of seeing what he expected – little to no picture on the plates- we was astounded to see an a fully exposed plate. The minerals had fluoresced without being first exposed to radiant energy! Becquerel had discovered radioactivity – or the spontaneous emission of nuclear radiation, he just didn’t realize it yet! In
