日本原子能研究所等单位合作研究了γ射线对Bi_(1.3)Pb_(0.5)sr_2Co_2Cu_3O_10超导体的辐照,考察了辐照对超导电学性能的影响。在室温下将该材料以Co~(60)γ射线辐照,辐照剂量从1.5MR/h逐渐升至50MR/h,测量电阻率与转变温度的变化。实验结果表明,样品在25.25MR/h辐照时,临界转变温度由103.4K升至104.1K,且随着辐照量的增加, Japan Atomic Energy Research Institute and other units to study the γ-ray irradiation of Bi 1.3 Pb 0.5 Sr 2 Co 2 Cu 3 O 10 superconductors. The effects of irradiation on the superconductor electrical properties were investigated. The material was irradiated with Co ~ (60) γ-ray at room temperature, and the irradiation dose was gradually increased from 1.5 MR / h to 50 MR / h. The change of resistivity and transition temperature were measured. The experimental results show that when the sample is irradiated at 25.25MR / h, the critical transition temperature increases from 103.4K to 104.1K, and with the increase of irradiation amount,
