Czechoslovak-French project of a plant to produce concentrated radon at Gif near Paris (1935-1939)
Těšínská, Emilie
The paper outlines the history of a common project of the Czechoslovak Ministry of Public Works and the French firm Société Nouvelle des Substances Radioactives dating back to 1935-1938. The project aimed at building a plant to produce concentrated radon within the premises of the Society’s laboratories at Gif near Paris. The plant, put into operation in 1937, was equipped with an apparatus of Mund-Porter type constructed by Czechoslovak firm Pavel Meissel in Brno and containing radium salt solution (502 mg Ra-element) hired by the Czechoslovak state. Czech physicist František Běhounek and Russian emigree Alexis Jakimach took an active part in the project implementation. The project ended under dramatic historical circumstances of years 1938-1939 when Czechoslovakia was occupied by Nazi Germany.

Discovery of Natural Radioactivity and New Development of the Town of Joachimsthal , Bohemia in the first half of the 20th Century
Těšínská, Emilie
Early research into natural radioactivity, closely connected with the uranium minerals, stimulated new development of the old mining town of Joachimsthal in Bohemia in the first half of the 20th century. Radioactive waste material from the uranium dye production in Joachimsthal served as material for the first radium preparations processed by Pierre and Marie Curie. The high concentration of radon in watter of Joachimsthal mines was measured by Austrian physicists Heinrich Mache and Stephan Meyer in 1904. In 1906, the first private radon spa was organized in Joachimsthal by medical doctor Leopold Gottlieb.
