Why does radium glows in dark?
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".
