Uranium Glass: A Glowing Alternative to Conventional Sources of Radioactivity

There is a relatively simple way of using radioactive
material in classroom experiments: uranium glass,
which provides teachers with a suitable substance. By
using the right computer software and a radiation sensor, it
can be demonstrated that uranium glass emits radiation at a
greater rate than the background radiation and with the aid
of UV light a bright green luster appears. Therefore, with two
pieces of uranium glass, students can learn about two different
physical phenomena: fluorescence and radioactivity.
