CWO is an excellent scintillator for gamma-rays with energy > 1 MeV, and good for most applications over 650 keV. This property enables to limit the unwanted background activity that is usually measured on NaI(Tl).

Energy resolution of Re = 9.9% is slightly higher than that of NaI (8.7%) but can be adequate in most applications.

Volumic price is roughly twice that of NaI, but being three times more efficient at full absorption peak, dimensions can be reduced in consequence, depending on the application.

Its application is Detection, container checking etc.
