Abstract:
1. A radiation-proof resin composition, comprising: a polymer comprising chlorine; a radiation resistance providing agent for providing the polymer with a radiation resistance, the radiation resistance providing agent comprising an antioxidant and a processing aid; an amorphous inorganic material for capturing an ionic component generated in the polymer by radiation application, the amorphous inorganic material comprising a baked clay not more than 2.0 μm in an average grain size; and a reinforcing material for reinforcing a mechanical strength of the polymer, the reinforcing material comprising a carbon black not more than 200 nm in an average grain size, an amount of the reinforcing material being not more than that of the amorphous inorganic material, wherein the antioxidant is added to 100 parts by weight of the polymer at an amount not less than 2 parts by weight, wherein the processing aid is added to 100 parts by weight of the polymer at an amount not less than 5 parts and not more than 40 parts by weight, wherein the amorphous inorganic material and the reinforcing material are added to 100 parts by weight of the polymer at a total amount not less than 40 parts and not more than 120 parts by weight, wherein the reinforcing material is added to the polymer at a rate of not less than a fifth and not more than one relative to a unit amount of the amorphous inorganic material.
