Which dosimeter uses a blue light to cause green light to be emitted from the crystal?

Explanation:
Optically stimulated luminescence dosimeters work by using light to release stored energy from the crystal. Radiation creates trapped electrons in the crystal lattice. When blue light shines on the material, those trapped electrons gain just enough energy to be released. As they recombine, they emit light, typically in the green region of the spectrum. The amount of this emitted light is proportional to the radiation dose received, and it is read out by a detector. This readout method is what sets OSL apart from the others: heating releases stored energy in TLDs, film badges rely on photographic changes, and pocket dosimeters use an ionization chamber.
