Application of radioactive substances in Medicine and Biology

Today we often hear about radioactive substances killing people or victims of cancer because radioactive material comes from nuclear weapons tests . However, that radioactive material, at first used to treat cancer.

The discovery of X-rays by Wilhelm in November 1895 symbolizes the revolution in the medical world. From then on, we can " look inside " the human body.

And the discovery of artificial radioactivity produced by Irène and Frédéric Joliot-Curie has enabled the ability to produce radioactive isomers of all natural elements that have allowed the Hach Nhan Medical sector to emerge. Isomers give different applications, from medical studies to diagnostic and therapeutic applications.

Memorable years

- 1895: Wilhelm Conrad Röentgen (Germany) explores X-rays and the ability to take pictures with X-rays,

- 1896 July, Dr. Victor Despeignes (Lyon) reported the first cancer treatment with X-rays

- 1897 Dr. Antoine Béclère places his first X-ray machine in a hospital in Paris.

- December 1898, Pierre and Marie Curie discovered Radium radioactivity.

- 1900 The two Otto Walkhof and Friedrich Giesel reported their observations of the biological results of Radium on the skin like X-rays.

- 1901 Pierre Curie and Henri Becquerel publish the "Physical Effects of Radium". A skin specialist at Saint Louis Paris Hospital, Henri Danlos, publishes the results of the treatment of Lupus with Radium.

Doctors test more and more on other diseases.

- The Perthes, the Germans, began the technique of curing radiation

- 1904-1906 Jean Bergonié and Louis Tribondeau prove that cancer cells are more sensitive than healthy cells. Then they laid the first biological foundation for X-ray therapy.

- 1905 Understanding of the good effect of Radium rays to treat hives of the skin and cervix, that was the introduction of Curiehexie (Curie therapy department).

- 1906 Armet de Lisle, the Radium enterprise, advanced the establishment of a laboratory to study the biological and medical effects of Radium. Create Radium therapy department. (Radiumthérapie)

- December 1909, University of Paris and Pasteur Institute decided to build the Radium Institute.

- 1914-1918 Marie Curie assistant Antoine Béclère as head of the X-ray zone for the army.

- 1918 Established French-British-American Association to fight cancer.

- 1920 Established Curie

- 1921-1928 Established 21 anti-cancer centers for Paul-Brousse hospital in Villejuif

- 1923 Georg de Hevesy (Suède, Sweden) uses isomers as biochemical marks (especially for plants), a way he imagined in 1913

- 1924 Two American physicians, Blumgart and Weiss, first used Radium C to calculate the blood circulation rate from one arm to the other.

- 1934 Irène and Frédéric Joliot-Curie discover artificial radioactivity
