    摘要： 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.
