Zn
Zinc
Z = 30 · Transition Metal · 65.4 u
Nuclear Engineering Significance
Injected as depleted zinc (enriched in Zn-64) into BWR and PWR primary coolant to reduce Co-60 incorporation into oxide films on piping, lowering occupational radiation dose. Natural zinc thermal absorption (σ_a = 1.1 b) is low.
