Radium
Radium is a chemical element with symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is almost colorless, but it readily combines with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1600 years and decays into radon gas (specifically the isotope radon-222). When radium decays, ionizing radiation is a product, which can excite fluorescent chemicals and cause radioluminescence.
Radium, in the form of radium chloride, was discovered by Marie Curie 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 1910.

Radium (software)
Radium is a proprietary Internet radio player application, used for listening to internet radio streams. It emphasizes a minimalist user interface. The application does not have a main window, instead opting to provide the entire user interface through its main menu. Users can either listen to Radium's built-in selection of internet radio networks, or add their own networks provided that the their stream URL's are known. The program has been praised for its unobtrusiveness, low system resource usage, and intuitive user interface, but has also been criticized for its lack of recording functionality as of version 2.5.1.
Radium is available as a free 30-day trial for Mac OS X, after which users are required to buy a license for $9.99 USD to continue using the program; minor updates are free for all users.
