‎First appearance of the six landmark papers in which Becquerel documents his discovery of Radio-activity, PROMPTING THE NUCLEAR AGE.Becquerel was an expert in fluorescence and phosphorescence, continuing the work of his father and grandfather. Follwing the discovery of X-rays by Röntgen, Bexquerel investigated fluorescent materials to see if they also emitted X-rays. He exposed a fluorescent uranium salt, pechblende, to light and then placed it on a wrapped photographic plate.He found that a faint image was left on the plate, which he believed was due to the pichblende emitting the light it had absorbed as a more penetrating radiation.. However, by chace, he left a sample that had not been exposed to light on top of a photographic plate in a drawer. he noticed that the photographic plate also had a a faint image of the pechblende. After several chemical tests he concluded that these ""Becquerel rays"" were a property of atoms. He had, by chace, discovered radio-activity and prompted thee beginning of the nuclear age. He shared the Nobel Prize for Physics in 1903 with Marie and Pierre Curie. The ""Becquerel Rays"" were later discovered to be a composite of three forms of emanation, distinguished by Rutherford as alpha, beta and gamma rays.Dibner: 163 (the later Mémoire from 1903) - PMM: 393 (1903- Mémoire) - Garrison & Morton: 2001 (only the first paper). - Magie ""A Source Book in Physics"" p. 610 ff. - Norman:157.‎

‎First edition of Becquerel's Nobel Lecture.""Becquerel attended a session of the 'Académie des Sciences' in Paris on 20 January 1896, when Jules Henri Poincaré exhibited a series of radiographs sent to him by Röntgen. He, like others, observed that the emission of X-rays from the cathode tube was accompanied by strong phosphorescence of the glass. He therefore suspected that other forms of induced phosphorescence might be accompanied by other hithero unknown rays. In February 1896 Charles Henry reported to the 'Académie' his discovery of that phosphorescence could be induced in certain substances by exposure to sunlight. In the same month Becquerel reported that uranium was among these substances. Like all his other early papers on the subject, this appeared in the 'Comptes rendus' and was entitled 'Sur les Radiations Invisibles' émises par les Corps Phosphorescents'. In a second paper, 'Sur quelques Propriétés Nouvelles des Radiations Invisibles', he reported the astonishing fact that uranium was capable of fogging photographic plates even without previous exposure to sunlight and when the plates themselves were completely protected from ordinary light. In a third paper, March 1896, 'Sur les Radiations invisbles émises par les d'Uranium' Becquerel discarded phosphorescence completely and declared that the emanations from uranium constituded an entirely new and unsuspected property of matter, which in his seventh paper he named 'radioactivité'. He also found that the uranium rays discharged a gold-leaf electroscope, which is still used as one method of detecting radio-activity.Becquerel also discovered that the residue of pitchblende, a natural uranium oxide, after the uranium had been extracted from it was about four times as radio-active as uranium itself. He therefore suggested to the Curies the importance of further investigations of the ore, with the result that they discovered radium. He continued to work on the subject until 1903, in which year he collaborated with Pierre Curie in a paper, 'Action Physiologique des Rayons du Radium', which is the starting-point of the treatment of disease by radio-active substances. In that year he also published ... ('Recherches sur une Propriété Nouvelle de la Matière' - the offered item) ... which is his definitive work, containing a chronological narrative of his investigations, his mature conclusions and a bibliography of two hundred and fourteen treatises on radio-activity, dating from his own first paper in 1896. The rays emitted by uranium were named in his honour 'Becquerel' rays. They were later discovered to be a composite of three forms of emanation, distinguished by Rutherford (in 1919) as alpha, beta and gamma rays and identified thus: alpha as helium nuclei, beta as electrons, and gamma as powerful X-rays."" - (PMM).In 1903 Becquerel shared the Nobel Prize in Physics with the Curies ""in recognition of the extraordinary services he has rendered by his discovery of spontaneous radioactivity"". ‎

‎First appearance of this historical paper in which Becquerel relates THE FIRST EVIDENCE OF A RADIOACTIVE TRANSFORMATION. ""Nothing that Becquerel subsequently accomplished (after his discovery of radioactivity in 1896) was as important as this discovery, by which he opened the way to nuclear physics. Nevertheless, there were two other occasions on which he stood directly on the path of history: when he identified electrons in the radiations of radium (1899 - 1900) and when he published the first evidence of a radioactive transformation (1901). (The paper offered).""(DSB).""To prove his supposition that the uranium would recover its activity, Becquerel set aside some of the inactive uranium solution and its radioactive barium sulfate precipitate for a period of 18 months. Late in 1901, he found that the uranium had completely regained its activity, whereas the barium sulfate precipitate had become completely inactive. Becquerel wrote: ""The loss of activity ... shows that the barium has not removed the essentially active and permanent part of the uranium. This fact constitutes, then, a strong presumption in favor of the existence of an activity peculiar to uranium, although it is not proved that the metal be not intimately united with another very active product.""‎
