It is a radium salt of hydrogen chloride. It was the first radium compound isolated in a pure state. Marie Curie and André-Louis Debierne used it in their original separation of radium from barium. The first preparation of radium metal was by the electrolysis of a solution of this salt using a mercury cathode. [2] [1]: 3
Radium carbonate is a chemical compound of radium, carbon, and oxygen, having the chemical formula Ra C O 3. It is the radium salt of carbonic acid. It contains radium cations (Ra 2+) and carbonate anions (CO 2− 3). This salt is a highly radioactive, amorphous, [4] white powder that has potential applications in medicine.
Tho-Radia, a cream containing radium bromide, notable for its iconic advertising using the name of Dr. Alfred Curie, who shared the surname of Pierre and Marie Curie but had no connection to them. Radithor, a solution of radium salts, which was claimed by its developer William J. A. Bailey to have curative properties.
Radium oxide (RaO) has not been characterized well past its existence, despite oxides being common compounds for the other alkaline earth metals. Radium hydroxide (Ra(OH) 2) is the most readily soluble among the alkaline earth hydroxides and is a stronger base than its barium congener, barium hydroxide. [3]
Radium bromide is the bromide salt of radium, with the formula RaBr 2. It is produced during the process of separating radium from uranium ore . This inorganic compound was discovered by Pierre and Marie Curie in 1898, and the discovery sparked a huge interest in radiochemistry and radiotherapy .
Sels de Radium, established near the family quinine plant at Nogent-sur-Marne, was dedicated to the manufacture of radium salts, and related products, using the Curie method. This included the development of devices that were used to ship the radium, or actually harness its radiation in a laboratory setting. [3]

Radium sulfate (or radium sulphate) is an inorganic compound with the formula RaSO 4 and an average molecular mass of 322.088 g/mol. [3] This white salt is the least soluble of all known sulfate salts. [4] It was formerly used in radiotherapy and smoke detectors, but this has been phased out in favor of less hazardous alternatives.
