SUMMARY
Gamma rays can damage metals, making them brittle, but the extent of this damage is significantly less than that caused by neutron radiation. In high-energy scenarios, such as p-D fusion, gamma radiation poses a hazard, yet it is estimated to cause only about 0.1% of the damage compared to neutron radiation. Neutrons interact with atomic nuclei, resulting in displacements and transmutation, while gamma rays primarily ionize electrons, affecting the metal's microstructure differently. The effects of gamma radiation on metals are generally negligible in practical applications, as heat produced during exposure often mitigates brittleness.
