It doesn't. Radium is radioactive. Radium plus a phosphor glows in the dark.
Old luminous watches and clocks, certain types of antique glassware, and some old paint products may contain radium. These items were commonly used before the harmful effects of radium were fully understood.
Radium silver is a type of silver alloy that contains a small amount of radium. This alloy was used in the early 20th century to produce luminous dials for watches and clocks due to radium's ability to glow in the dark. However, radium is radioactive and poses health risks, leading to the discontinuation of its use in consumer products.
"Illuminate your world with Radium!" "Shine bright like Radium!" "Glowing brilliance with Radium." "Radiant energy, powered by Radium."
The first name was radium; some isotopes had in the past other names.
No plural for radium.

Radium (Latin radius, ray) was discovered by Marie Skłodowska-Curie and her husband Pierre on December 21, 1898 in pitchblende. Radium was formerly used in self-luminous paints for watches, nuclear panels, aircraft switches, clocks, and instrument dials.
yes. Today's glow in the dark clocks are not made with radium, but with a light absorbing chemical. Those that glow red are actually LED, an electrical device. Radium dials were discontinued in the late 1950's, when it was discovered that workers who painted the dials had cancer of the jawbone, brought on by "sharpening" the brush by putting it in their mouths with the raduim on it.
Yes. These were originally known as Radium dials until the dangers of Radium were realised (people used to paint their teeth with Radium, to make them glow in the dark, with the result their jaws degenerated and literally fell off their skulls). You can still get radiation poising from old Radium dials, as the half-life of Radium is 1600 years. Phosphor dials (and sometimes Tritium) replaced Radium dials and is a much safer method of making the hands of analogue clocks, watches and other dialled instruments glow in the dark. How long they glow is dependent upon the amount of light absorbed by the phosphor.
It reflects and doesn't wear as fast as regular paint. Drivers need a reflective surface at night.

No plural for radium.
Radium primarily forms compounds with oxygen, such as radium oxide (RaO), radium peroxide (RaO2), and radium hydroxide (Ra(OH)2). It can also form compounds with other elements, such as radium chloride (RaCl2) and radium sulfate (RaSO4). These compounds are generally highly radioactive due to the nature of radium as a radioactive element.
