Scintillating plastics resistant to crazing and fogging, methods of making and using the same are disclosed. The scintillating plastics include: one or more primary polymers present in an amount ranging from about 40 wt % to about 95 wt %; one or more secondary polymers present in an amount ranging from about 1 wt % to about 60 wt %; and one or more fluors present in an amount ranging from about 0.1 wt % to about 50 wt %. Methods of making such plastics include: creating a homogenous mixture of precursor materials including primary polymer, secondary polymer, and fluor in the amounts set forth above; and polymerizing the homogenous mixture. Methods of using such plastics include: exposing the scintillating plastic to one or more extreme environmental conditions for a predetermined amount of time without generating crazing or fogging within the scintillating plastic. Various additional features and specific embodiments of these inventive concepts are also disclosed.

There is provided a scintillator array to be used for a neutron detector capable of detecting high energy neutrons with high definition and high efficiency. A scintillator array comprises a structure including a plurality of stacks layered each other. Each of the stacks has in sequence: a light reflector including ceramics or single-crystal silicon; a first film to react with a neutron incident along a direction intersecting a lamination direction of the stacks and thus emit a radiation ray; a second film including a material to reflect light; and a scintillator to emit light in response to the radiation ray. The light from the scintillator is reflected by the reflector and the second film to propagate an inside of the scintillator and thus to be led to an outside of the structure.

Provided is a radioactive contamination inspection apparatus including a plastic scintillator, a light receiving element, a light guide configured to allow scintillation light emitted from the plastic scintillator to reach the light receiving element, a light shielding housing including an incidence window, and a thin film layer structure provided between the incidence window provided in the light shielding housing and the plastic scintillator, and including a protective film, a light shielding film, and a reflective film in the stated order from the incidence window side. A side surface of the light guide is made up of a diffused reflection surface. The reflective film is disposed with an air layer placed between the reflective film and the plastic scintillator. A surface of the reflective film, which faces the plastic scintillator, is made up of a specular reflection surface.

Provided are a scintillator with improved energy sensitivity dependence within the energy range of diagnostic X-rays, more specifically in the range of 40-150 kV, and a radiation dosimeter using same. Due to the scintillator comprising a photopolymer resin that contains a polymerizable monomer, a filler, and a photopolymerization initiator, energy sensitivity dependence within the range of 40-150 kV is improved. Furthermore, changes in relative sensitivity within this energy range can be reduced to 3% or less by containing an inorganic fluorescent substance such as Zn.sub.2SiO.sub.4.

Embodiments include a scintillator material, a scintillator system, and/or a method of detecting incident radiation using a scintillator material, or scintillator system, comprising a polymer material that comprises chromophores. Additional embodiments provide a scintillator material, scintillator system, and/or a method of detecting incident radiation using a sctintillator material, or scintillator system, comprising a polymer material having one, two, three, or more, organic dyes dissolved therein wherein the polymer material having the one, two, three, or more dyes dissolved therein comprises chromophores. At least one of the dyes, termed the base dye, has a concentration in the range 0.5 to 3.5 mol/L. In an embodiment, the base dye has a concentration in the range 1.0 to 3.0 mol/L. This base dye concentration is high enough to achieve a substantial triplet-triplet state annihilation rate despite the negligible diffusion of the dye in the rigid polymer matrix.
