Systems and methods for the simultaneous detection and identification of
radiation species, including neutrons, gammas/x-rays and minimum ionizing particles
(MIPs). A plurality of rectangular and/or triangularly shaped radiation sensitive
scintillators can be configured from a plurality of nano-sized particles, dopants
and an extruded plastic material. A wavelength-shifting fiber can then be located
within a central hole of each extruded scintillator, wherein the wavelength-shifting
fiber absorbs scintillation light and re-emits the light at a longer wavelength,
thereby piping the light to a photodetector whose response to the light indicates
the presence of radiation The resulting method and system can simultaneously detect
neutrons, gamma rays, x-rays and cosmic rays (MIPs) and identify each.
