1. A scintillation crystal comprising a rare earth silicate, a first dopant, and a second dopant,
wherein:
the first dopant is an activator;
the second dopant includes a Group 2 element, and wherein the scintillation crystal has a decay time of no greater than 40 ns, wherein the Group 2 element has a second atomic concentration does not exceed 200 ppm atomic based on a total rare earth content of the scintillation crystal.
