Radium chloride radium chloride is weakly paramagnetic with a magnetic susceptibility of 1.05. It also differs from barium chloride by the flame color, which is red as opposed to green for barium chloride. Radium chloride is still used for the initial stages of the separation of radium from barium during the extraction of radium from pitchblende. The large quantities of material involved (tonnes of ore for milligrams of radium) favour this less costly (but less efficient) method over those based on radium bromide or radium chromate (used for the later stages of the separation). It was also used in medicine to produce
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
