Sr
Strontium
Z = 38 · Alkaline Earth Metal · 87.6 u
Nuclear Engineering Significance
Important fission product. Sr-90 (t₁/₂ = 28.8 y) is one of the dominant contributors to spent fuel radioactivity and heat generation in the first few hundred years. Its high fission yield and biological hazard (bone-seeking) make it a key isotope in waste management and accident consequence analysis.
