Claim Text:
1. A sensor for detecting gamma radiation, the sensor comprising: a conjugated imidazole having the following structure: where at least one of R1, R2, and R3 are conjugated organic groups and wherein the conjugated imidazole has a nanofiber morphology, is present in a porous hydrophilic material, or has both the nanofiber morphology and is present in the porous hydrophilic material; a radical generating component, wherein the conjugated imidazole is capable of reacting with a radical or ion formed by a reaction of the gamma radiation with the radical generating component to decrease a molar extinction coefficient of the conjugated imidazole or to quench fluorescence of the conjugated imidazole; and a radiation detection indicator operatively associated with the conjugated imidazole configured to indicate a decrease in the molar extinction coefficient of the conjugated imidazole or a quenching of fluorescence of the conjugated imidazole.
