NaI(Tl)

From Detec-Rad.com

The use of NaI(Tl) crystals in sealed units is counterbalanced by the fact that they have the greatest light output among all the scintillators and a convenient emission range matching the maximum efficiency of photomultipliers with bialkali photocatodes. Moreover, large-size NaI(Tl) crystals can be produced at low cost.
