Litrospheres Glow for 12 Years

By Anne Marie Helmenstine, Ph.D., About.com GuideDecember 16, 2007

Follow me on:

A company that makes glow-in-the-dark paint (MPK Co.) has developed self-luminous microspheres that will continuously glow for approximately 12 years (half-life). The spheres are inexpensive to produce, non-toxic, and can be made to glow in any color. They contain a beta-emitting radioactive gas, which provide the energy for fluorescence, but cannot penetrate the glass or polymer wall of the spheres. Litrospheres are unaffected by normal temperatures and are 5000-lb crush resistant. I first heard about the spheres from a link to Treehugger.com, which directs readers to the Pure Energy Systems wiki entry for further information.
