Radium chemicals and cause radioluminescence. Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911. In nature, radium is found in uranium and (to a lesser extent) thorium ores in trace amounts as small as a seventh of a gram per ton of uraninite. Radium is not necessary for living organisms, and adverse health
V. G. Khlopin Radium Institute in Bondyuga (Tatarstan), which was used by and others to generate Russia's first high-enriched radium compound. The Radium Institute was renamed to V. G. Khlopin in his honor in 1950. At the Radium Institute, the first European cyclotron was proposed by George Gamow and in 1932, being constructed with the help of Igor Kurchatov, operational by 1937. V. G. Khlopin Radium Institute The V. G. Khlopin Radium Institute, also known as the First Radium Institute, is a research and production institution located in Saint Petersburg specializing in the fields of nuclear physics, radio- and geochemistry, and on ecological topics, associated
