A radiation detector includes: a detector case which has an opening portion, a reflector which is attached to the opening portion of the detector case, a plastic scintillator which is disposed inside of the detector case, with a clearance from the reflector, a light guide into which fluorescence emitted from the plastic scintillator enters, a photo multiplier tube at which the fluorescence having passed through the light guide enters, and a pre amplifier which converts an output of the photo multiplier tube into a current pulse; wherein the plastic scintillator or the light guide has a soaked layer of ammonia which is formed on a surface thereof. This radiation detector is improved in the chemical resistance to the process fluid which includes a corrosive gas.
