Increased Supply of Radium
Since the discovery in the Congo region of important radioactive deposits, Belgium has acquired almost a monopoly of the radium market. Since the first discoveries of uranium in the Katanga copper mines in 1920, numerous researches carried out by the Union minière have made it possible to increase the output. The mines at Chinkolwbe (Kasalo) furnish the mineral substances from which the radium is separated in the new works at Oolen, near Antwerp, which are affiliated with the Société Générale Metallurgique of Hoboken.
