Abstract:
1. A radiation detector system comprising: (a) scintillation array stack; (b) photomultiplier tube; (c) shaping amplifier; (d) discriminator; (e) anti-coincidence module; (f) radiation counter; and (g) detector case; wherein said detector case is configured as a rectangular box structure; said rectangular box structure comprises a box length dimension larger than the depth of said rectangular box structure; said rectangular box structure comprises a box width dimension larger than the depth of said rectangular box structure; said scintillation array stack comprises scintillation materials responsive to more than one band of radiation; said scintillation array stack is configured in a planar rectangular form factor conforming to the perimeter of said rectangular box structure; said rectangular box structure is configured to contain said scintillation array stack and said photomultiplier tube; said scintillation array stack is in proximity to said photomultiplier tube, said photomultiplier tube receiving excitation input from said scintillation array stack; said shaping amplifier receives the output of said photomultiplier tube and produces one or more radiation pulses based on the excitation and output of said photomultiplier tube; said discriminator receives said radiation pulses and produces a pulse output depending on whether said radiation pulses fit a threshold and pulse width profile associated with a radiation type; and said anti-coincidence module is configured to receive said pulse output and determine whether said pulse output is valid for a given radiation type by the use of a truth table wherein:
