There may be no visible signs that radioactivity is present. Although it remains radioactive for thousands of years, the paint has broken down chemically over time, and so the devices may no longer glow in the dark. The radium luminous paint was often white when it was new but would typically tarnish to yellow. In general, radium luminous devices are not identified as containing radioactive materials.

How can I identify a radium luminous device?.Devices containing radium luminous compounds.Only a radiation detection instrument can confirm if a device contains radium luminous compounds. Radium luminous devices are generally not identified or marked as containing radioactive materials. When new, the radium luminous paint was often white, but typically tarnished to yellow as it aged. Although the devices no longer glow in the dark due to the breaking down of the paint over time, the radium continues to be radioactive for thousands of years. The radium luminous device itself is not radioactive however the radioactivity is associated with the radium luminous paint in the device. We refer to these products as radium luminous devices. Have you ever wondered if any of your collectibles might be radioactive or dangerous? Do you own any old wristwatches or clocks, marine compasses, aircraft instruments or other military items? Until the 1960s, various military and consumer products were manufactured using a radium-based paint that glows in the dark. Radium is long-lived (its half-life is more than 1,600 years) and decays with time into radon gas, and then finally stabilizes as lead. It is a decay product of uranium that is found in almost all rocks and soils.
What is radium? Radium, known scientifically as Ra-226, is a radioactive element found naturally in the environment. Identifying a device that contains a radium luminous compound
