| Abstract | ||
| Copper wires extensively used in cable manufacturing due to their high electrical conductivity (5.96×10⁷ S/m), exceptional ductility, and strong corrosion resistance, making them ideal for power transmission, electronics, and telecommunications. Their high thermal conductivity (~400 W/m•K) and mechanical durability further enhance their suitability for harsh environments. This study investigates the effects of γ-radiation on the electrical conductivity, tensile strength, elongation, and chemical stability of commercially produced copper wires. Samples were irradiated using a ⁶⁰Co γ-ray source at incremental doses (50, 100, 150, and 200 kGy). Electrical resistivity measurements (four-point probe) and mechanical tests (universal testing machine) showed negligible variation (±2%) between irradiated and control samples, confirming copper’s radiation-hardened properties for applications in nuclear and aerospace industries. | ||
