一般注記25種類のゴム,プラスチック材料について、使用環境における耐放射線性を模擬する酸素加圧下$\gamma$線照射する加速試験で評価し、従来実施されていた空気中高線量照射試験による耐放射線性評価と比較した。実用材料と同等の配合を施し、可能な限りその内容を明示した。各材料の引張り試験(破断時伸び,引張強度,100\%又は200\%モジュラス),電気絶縁抵抗,ゲル分率,密度測定を行い、使用環境を模擬する放射線酸化劣化の条件と高線量率照射における非酸化条件における、線量依存性データを示し、力学特性,電気特性と放射線化学反応との関係を考察した。
The radiation resistance of 25 type polymer materials as plastics and rubbers applied in practical environments was evaluated by the accelerated testing of $\gamma$-ray irradiation under oxygen pressure, and compared with the radiation resistance determined from the traditional testing by irradiation with a high dose rate in air. The polymer materials were formulated to be similar or equivalent to practical materials, and the most of formulation (chemical compounds and quantities) were disclosed. For all materials, the tensile properties (elongation at break, ultimate strength, 100\% or 200\% modulus), electric resistivity, gel-fraction, and density were measured after irradiation in oxidation conditions and non-oxidation conditions. The data of relations between each properties and total dose at various conditions were compiled, and the relations among the changes of mechanical properties, electrical properties, and radiation induced chemical reactions were discussed.
