← ScienceWhich risk increases when hydrogen isotopes fuel magnetically-confined plasma fusion?
A)Neutron embrittlement in vacuum vessel✓
B)Gamma radiation inducing sample degradation
C)Accelerated alpha particle energy depletion
D)Spontaneous fission product chain reactions
💡 Explanation
Neutron embrittlement increases because deuterium-tritium fusion produces high-energy neutrons. These neutrons bombard the vessel walls, causing defects in the material’s crystal structure; therefore embrittlement, rather than gamma or alpha radiation risks are amplified.
