ABSTRACT:
A crystal for a scintillator is a single crystal of Bi.sub.4 Ge.sub.3 O.sub.12 containing up to 0.5% by weight of Bi.sub.4 Si.sub.3 O.sub.12 and/or up to 50 ppm of Gd. The light output of this crystal as a scintillator can be increased by about 20% as compared with the light output of the conventional crystal of additive-free Bi.sub.4 Ge.sub.3 O.sub.12.
