Patent ID: 8614420

Claim:
A radiation detection system comprising: a first scintillating material to produce a first light in response to the radiation detection system receiving a particular radiation, wherein the first scintillating material has a first light yield; a first photosensor coupled to the first scintillating material, wherein the first photosensor has a first quantum efficiency with respect to the first light; a second scintillating material to produce a second light in response to the radiation detection system receiving the particular radiation, wherein the second scintillating material has a second light yield; and a second photosensor coupled to the second scintillating material, wherein the second photosensor has a second quantum efficiency with respect to the second light, wherein: the first scintillating material is different from the second scintillating material; a first product is the first light yield times the first quantum efficiency; a second product is the second light yield times the second quantum efficiency; a product difference is an absolute value of a difference the first product minus the second product; a quotient is the product difference divided by a greater of the first and second products; and the quotient is no greater than one half of the energy resolution of the first scintillating material.
