It doesn't. Radium is radioactive. Radium plus a phosphor glows in the dark.

Is radium a compound or a element?
Radium is a chemical element, not a compound.
What is the cost of radium?
Radium is not a common commercial product.
What is radium chloride?
Radium chloride, RaCl2, was the first radium compound to be prepared in a pure state and was the basis of Marie Curie's original separation of radium from barium. The first preparation of radium metal was by the electrolysis of a solution of radium chloride using a mercury cathode.
What is radium common name?
The first name was radium; some isotopes had in the past other names.
Where can one purchase radium?
Buy a bunch of old clocks and watches that have luminous numbers and the pointers that glow also. That is radium. Some of it was painted on by hand. In order to keep their paint brush sharp the worker would put it in their mouth and pull it out. Sucking on radium has bad health effects. The buildings where this was done are still very contaminated and the painters died of radium poisoning. Not sure if you can legally own it. Transporting it may be a crime. Possessing it is very dangerous and not recommended at all. Madam Currie, who discovered it, died from it. All isotopes should be kept in a secure and shielded place. Handling it only when necessary and with full protection from it.
Who discovered radium and why was it significant?
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.
Are glow in the dark clocks safe?
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.
Why radium paint is used for road sign?
It reflects and doesn't wear as fast as regular paint. Drivers need a reflective surface at night.
Is phosphorus on some hands of the clock?
No, phosphorus is not found on any hands of the clock. The hands of a clock are typically made of metal or plastic materials and do not contain phosphorus. Phosphorus is a chemical element that is not commonly used in the construction of clocks.

What colour is radium?
Radium is nearly pure white. When it is exposed to air, though, it immediately oxidizes, turning black. The heaviest of the alkaline earth metals, radium is a chemical element whose atoms - like those of the other alkaline earth metals - have two electrons in their outermost shell; this causes them to react readily and form numerous compounds. The luminescent quality in radium made it ideal for use in self-luminous paints for watches, instrument dials, clocks and the like. Unaware of the danger of the extreme radioactivity of the element, many watch-dial painters who shaped their paintbrushes by putting them between their lips, died from the extended exposure to the radium in the paint. With its hazards come benefits. Today, radium is used medically to treat some kinds of cancer. On this date in 1898, scientists Pierre and Marie Curie and Gustave Bemont discovered radium in pitchblende that came from the now Czech Republic.Radium has probably a silvery metallic appearance.
