‎First printing of a milestone paper in medical physiology as the report given of the physiological effects (radiactive burns) on his own arm lead directly to study the actions of radium on different diseases and its medical use in general. Radium's use gave promising results as it destroyed diseased cells, tumors and some cancers. The therapeutic method was to be called ""Curietherapy"".""The German scientists Walkhoff and Giesel announced in 1900 that the new substance had certain physiological effects" Pierre Curie at once applied the technique which seemed to him most practical. Indifferent to danger, he exposed his arm to the action of radium. To his joy, a lesion appeared. He watched over it, followed its evolution and, in a report to the Academy, phlegmatically described the symptoms observed (the offered paper).After the action of the rays, the skin became red over a surface of six square centimetres the appearance was that of a burn, but the skin was not painful, or barely so. At the end of several days the redness, without growing larger, began to increase in intensity on the twentieth day it formed scabs, and then a wound which was dressed with bandages" on the forty-second day the epidermis began to form again on the edges, working toward the centre, and fifty-two days after the action of the rays there was still a surface of one square centimetre in the condition of a wound, which assumed a greyish appearance indicating deeper mortification.""

‎First printing of these four papers, constituting a revolution in time measuring, as Pierre Curie here defined a STANDARD FOR THE ABSOLUTE MEASURING OF TIME ON THE BASIS OF RADIOACTIVITY, and hereby departing from the relative measurements in geology and archaeology.After the discovery of Polonium and Actinium (1898 a. 1899 ) further discoveries followed. ""First came the announcement in 1899 by Marie Curie of induced radioactivity, brought about by the action of polonium or radium on inactive substances. The induced radioactivity persisted over a considerable period of time, a phenomenon of great concern to Pierre Curie. He took up the question with Debierne, with whom he published two papers in 1901(the first two papers offered)"" their experiments could be explained by Rutherford’s theory of emanation (radon), a radioactive gas emitted by radium. With J. Danne, Curie measured the diffusion coefficient of radium emanation in the air and proved, as Rutherford had done, that it liquefies at - 150°C. In order to clarify the nature of the emanation he studied the law of diminution of the activity of a solid after having removed it from a chamber in which a radium salt was present. In two notes presented to the Academy on 17 November 1902 and 26 January 1903 (the third and fourth papers offered), Curie showed that this activity diminishes according to an exponential law characterized by a time constant that, for the emanation, is equal to 5,752 days, regardless of the conditions of the experiment. The importance of this discovery, which marks the point of departure for all modern measurements of archaeological and geological dating, did not escape his, for at a meeting of the Société Française de Physidque in 1902 he defined a standard for the absolute measurement of time on the basis of radioactivity. Almost immediately Rutherford and Soddy showed that the exponential diminution was caused by the transmutation of radioactive elements."" (DSB. Pierre Curie).‎

‎First apperance of Villard's two papers in which he announced and described the discovery of a new type of radiation more powerfull and penetrating than alpha-and beta rays. The new type of rays was named by Rutherford as gammarays.""His (Villard)experiments in radioactivity led to the unexpected discovery of gamma rays in 1900. Villard recognized them as being different from x rays because the gamma rays had a much greater penetrating depth. He had discovered they were emitted from radioactive substances and were not affected by electric or magnetic fields. These came to be called gamma rays by another scientist, Ernest Rutherford. It wasn't until 1914 that Rutherford showed that they were a form of electromagnetic (EM) like light only with a much shorter wavelength than x rays. Now we know that gamma rays are a form of EM radiation similar to x rays. Gamma rays tend to have a higher energy and a shorter wavelength than x rays do. However, the dividing line between these two forms of radiation is not clearly defined. Scientists typically apply the term gamma ray to EM radiation with energies above several hundred thousand electron volts.""
