 note = {The enormous area of damage to Japan's Fukushima Daiichi nuclear power plant requires detectors with robust base substrates to monitor high-dose-rate environmental radiation with long- term stability. Undoped aromatic ring polymers have considerable potential as base substrates in radiation detection. Here, we characterise polycarbonate(PC), which has excellent transparency, shock, radiation, and  weather resistance, heat tolerance, and anti-abrasion qualities. It has a density of 1.20g/㎤, an excitation of 310nm, and short-wavelength emission with a maximum at 350-nm. By taking into account its emmision, we detemined an effective refractive index of 1.64.PC has a light yield that is 0.67 times that of undoped poly (ethylene terephthalate). These results reveal that readily available PC is an effective base substrate for use in large-area radiation detectors for the nuclear power plant recovery proccess.},
