Radiation doesn't glow itself, that's a popular stereotype. It can activate some luminophores. Usually, such luminophores contain metal salts and it is easy to introduce them into glass. For example, you can imagine that due to bad ecology living species are intoxicated by some metal (Barium or Zinc), and this is a luminophore.
