}} Someone of the older production examples (differentiated by the brownish color of their glow-in-the-dark markings, like the one in the photo) are slightly radioactive because of Radium-226 used in their dials. Newer ones, with teal or white paint color, use the non-radioactive phosphorescent paint.
