A chalcopyrite, colquiriite, neutron absorber loaded glass, or plastic scintillator based fiber optic plate for use in a neutron imaging system, including: a plurality of optical fiber segments disposed side-by-side adjacent to one another in a parallel array; and a binder material disposed between and coupling the plurality of optical fiber segments together. A diffuse reflective material is optically coupled to the plurality of first ends of the plurality of optical fiber segments. An optical detector device is optically coupled to the plurality of second ends of the plurality of optical fiber segments opposite the diffuse reflective material. Optionally, the fiber optic plate further includes a diffuse reflective material disposed one or more of on an exterior surface of each of the plurality of optical fiber segments and between the plurality of optical fiber segments.

A radiation detection device, including: a support structure; and a chalcopyrite crystal coupled to the support structure; wherein, when the chalcopyrite crystal is exposed to radiation, a visible spectrum of the chalcopyrite crystal changes from an initial color to a modified color. The visible spectrum of the chalcopyrite crystal is changed back from the modified color to the initial color by annealing the chalcopyrite crystal at an elevated temperature below a melting point of the chalcopyrite crystal over time. The chalcopyrite crystal is optionally aLiInSecrystal. The radiation is comprised of neutrons that decrease theLi concentration of the chalcopyrite crystal via aLi(n,&#x3b1;) reaction. The initial color is yellow and the modified color is one of orange and red. The annealing temperature is between about 450 degrees C. and about 650 degrees C. and the annealing time is between about 12 hrs and about 36 hrs.
