Energy response of some inorganic scintillators

It is known that densely ionizing particles give rise to a non-linear energy response in organic crystals, while in inorganic crystals in general the light output is proportional to the energy absorbed so that there is no difference between the intrinsic efficiencies forα-particles andγ-ray exoitation. The study of some inorganic silicate scintillators reported here shows, however, that they resemble the organic crystals in their non-linear energy response. Contrary to the behaviour of organic scintillators, prolongedα bombardment does not produce any perceptible change in the fluorescence efficiency of these scintillators. The non-linear energy response of these silicates is not explainable by the mechanism of scintillation hitherto proposed.
