Because today's glow in the dark stuff doesn't contain radium, it contains the stuff in fireflies and Mountain Dew.
It doesn't. Radium is radioactive. Radium plus a phosphor glows in the dark.

From many years radium is not used for watches (or other measuring instruments) dials.
Before it was known how harmful the radiation emitted by radium as it decays is to living tissue, it was applied to some products such as watch faces for its glow-in-the-dark property. Now we know better. Today, unless you are working in the field of nuclear medicine or you are mining uranium ore, you will not be running into radium.

Radium glows in the dark and is in glow bands

No, radium does not glow in the dark. If it did, then the whole world would be glowing in the dark. Rocks, soil, plants, and any living thing contains some radioactive material. The myth can be traced back to the "radium craze" of the early 20th century, when radium was just about added to everything. When the radium was added to paint, it became luminous. This was the origin of the "radium glow". In fact, it wasn't the radium glowing, but it was reacting with the copper and zinc in the paint, causing it to become luminous, in a phenomenon called "radio-luminescence".
They disperse.
Very. It appears in many glow-in-the-dark watches.
Radium.
i think it's because of this fluro chemical.
i think its radium
Due to radium which is element in periodic table.
radium was used in luminous paint and for theglow in the dark clock it as it emits radioactive decay that's why its not used in luminous paint now
