Becquerel was born in Paris, France into a wealthy family which produced four generations of physicists: Becquerel's grandfather (Antoine César Becquerel), father (Alexandre-Edmond Becquerel), and son (Jean Becquerel). [23] In 1906, Henri was elected Vice Chairman of the academy, and in 1908, the year of his death, Becquerel was elected Permanent Secretary of the Académie des Sciences. [5] Becquerel's other experiments allowed him to research more into radioactivity and figure out different aspects of the magnetic field when radiation is introduced into the magnetic field. Since the sun did not come out in the following days, I developed the photographic plates on the 1st of March, expecting to find the images very weak. Becquerel made a special study of the voltaic cell, telegraphy, and magnetism and wrote several books on these subjects. 4.2 out of 5 stars. [12][13] By 1861, Niepce de Saint-Victor realized that uranium salts produce "a radiation that is invisible to our eyes". 4.5. [5] Becquerel did not survive much longer after his discovery of radioactivity and died on 25 August 1908, at the age of 55, in Le Croisic, France. By 1896 Henri was an accomplished and respected physicist—a member of the Académie des Sciences since 1889—but more important than his research thus far were his expertise with phosphorescent materials, his familiarity with uranium compounds, and his general skill in laboratory techniques, including photography.

[7], In Becquerel's early career, he became the third in his family to occupy the physics chair at the Muséum National d'Histoire Naturelle in 1892. Becquerel reported this discovery to the Académie des Sciences at its session on February 24, 1896, noting that certain salts of uranium were particularly active.

Instituto Antoine Henri Becquerel, Mexico City, Mexico. On page 50 of volume 2, Edmond noted that Niepce de Saint-Victor had observed that some objects that had been exposed to sunlight could expose photographic plates even in the dark. ". On 2 March 1896 he reported: I will insist particularly upon the following fact, which seems to me quite important and beyond the phenomena which one could expect to observe: The same crystalline crusts [of potassium uranyl sulfate], arranged the same way with respect to the photographic plates, in the same conditions and through the same screens, but sheltered from the excitation of incident rays and kept in darkness, still produce the same photographic images. If one places between the phosphorescent substance and the paper a piece of money or a metal screen pierced with a cut-out design, one sees the image of these objects appear on the negative ... One must conclude from these experiments that the phosphorescent substance in question emits rays which pass through the opaque paper and reduce silver salts.[16][17]. "When different radioactive substances were put in the magnetic field, they deflected in different directions or not at all, showing that there were three classes of radioactivity: negative, positive, and electrically neutral. Instituto Antoine Henri Becquerel. Becquerel learned that the X rays issued from the area of a glass vacuum tube made fluorescent when struck by a beam of cathode rays. This opened up a whole new field of research to uncover the source of the mysterious energy.

The far more popular X rays could take sharper shadow photographs and faster. Closed Now. Research into phosphorescence. ).[15]. Henri made this discovery when he left a piece of radium in his vest pocket and noticed that he had been burnt by it. Instead the silhouettes appeared with great intensity ... One hypothesis which presents itself to the mind naturally enough would be to suppose that these rays, whose effects have a great similarity to the effects produced by the rays studied by M. Lenard and M. Röntgen, are invisible rays emitted by phosphorescence and persisting infinitely longer than the duration of the luminous rays emitted by these bodies. Antoine Henri Becquerel (/ˌbɛkəˈrɛl/;[2] 15 December 1852 – 25 August 1908) was a French engineer, physicist, Nobel laureate, and the first person to discover evidence of radioactivity. It required the extension in 1898 of radioactivity to another known element, thorium (by Gerhard Carl Schmidt and independently by Marie Curie), and the discovery of new radioactive materials, polonium and radium (by Pierre and Marie Curie and their colleague, Gustave Bémont), to awaken the world and Becquerel to the significance of his discovery.

Note that he is the father of A. E. Becquerel, and the grandfather of Henri Becquerel. Becquerel's earliest works centered on the subject of his doctoral thesis: the plane polarization of light, with the phenomenon of phosphorescence and absorption of light by crystals. [4] Henri started off his education by attending the Lycée Louis-le-Grand school, a prep school in Paris. This episode is sponsored by: Swinburne Astronomy Online, 8th Light. Henri then concerned himself with infrared radiation, examining, among other things, the spectra of different phosphorescent crystals under infrared stimulation. Becquerel made a special study of the voltaic cell, telegraphy, and magnetism and wrote several books on these subjects. He worked with Hittorff-Crookes tubes and the Ruhmkorff coil to investigate the violet … During 1896 Becquerel published seven papers on radioactivity, as Marie Curie later named the phenomenon; in 1897, only two papers; and in 1898, none. or.

Others may have noticed this before him, but his report in 1901 of the burn caused when he carried an active sample of the Curies’ radium in his vest pocket inspired investigation by physicians, leading ultimately to medical use.

By May 1896, after other experiments involving non-phosphorescent uranium salts, he arrived at the correct explanation, namely that the penetrating radiation came from the uranium itself, without any need for excitation by an external energy source. Another discovery was the circumstance that the allegedly active substance in uranium, uranium X, lost its radiating ability in time, while the uranium, though inactive when freshly prepared, eventually regained its lost radioactivity. One was to measure, in 1899 and 1900, the deflection of beta particles, which are a constituent of the radiation in both electric and magnetic fields. Antoine Henri Becquerel (born December 15, 1852 in Paris, France), known as Henri Becquerel, was a French physicist who discovered radioactivity, a process in which an atomic nucleus emits particles because it is unstable. In 1896 Henri Becquerel was using naturally fluorescent minerals to study the properties of x-rays, which had been discovered in 1895 by Wilhelm Roentgen.He exposed potassium uranyl sulfate to sunlight and then placed it on photographic plates wrapped in black paper, believing that the uranium absorbed the sun’s energy and then emitted it as x-rays. Frans natuurkundige. His grandfather had made important contributions in the field of electrochemistry while his father had investigated the phenomena of fluorescence and phosphorescence. Returning to the field he had created, Becquerel made three more important contributions.

When Ernest Rutherford and Frederick Soddy found similar decay and regeneration in thorium X and thorium, they were led to the transformation theory of radioactivity, which explained the phenomenon as a subatomic chemical change in which one element spontaneously transmutes into another.

Henri Becquerel's early work was concerned with the polarization of light, the phenomenon of phosphorescence and the absorption of light by crystals (his doctoral thesis). [9] Learning of Röntgen's discovery from earlier that year during a meeting of the French Academy of Sciences caused Becquerel to be interested, and soon "began looking for a connection between the phosphorescence he had already been investigating and the newly discovered x-rays"[9] of Röntgen, and thought that phosphorescent materials, such as some uranium salts, might emit penetrating X-ray-like radiation when illuminated by bright sunlight. Antoine Henri Becquerel [] (Fig. To test this hypothesis, he placed phosphorescent crystals upon a photographic plate that had been wrapped in opaque paper so that only a penetrating radiation could reach the emulsion. Starting with his grandfa-ther, members of three generations of the Becquerel family were physicists, and they had an extraordinary interest in phosphorescence and fluorescence.
