1. A method for detecting incoming radiation having a plurality of differing properties including at least one of first or second differing types, differing energies or differing incoming directions, the method comprising:
using a scintillator structure formed from first and second dissimilar scintillator materials, the first and second dissimilar scintillator materials emitting first and second different colors of light in response to the first or second differing types, differing energies or differing incoming directions of the incoming radiation;
using a first light detector responsive to only light generated from the first dissimilar scintillator material, to detect light having the first color;
using a second light detector responsive to only light generated from the second dissimilar scintillator material, to detect light having the second color;
generating a first output signal in response to detecting light having the first color, and generating a second output signal in response to detecting light having the second color; and
analyzing the first and second output signals to determine at least one property of the incoming radiation.
