← ScienceWhich risk increases when depleted uranium is enriched?
A)Spontaneous criticality becomes more likely✓
B)Radioactive half-life gets significantly shorter
C)Chemical toxicity becomes markedly higher
D)Neutron emission rates drop dramatically
💡 Explanation
Enrichment concentrates fissile isotopes, and increases the probability of a self-sustaining fission reaction via the effectiveNEUTRON MULTIPLICATION factor; therefore criticality risk rises, rather than half life decreasing; this depends on isotopic ratios, not uranium toxicity or neutron emission rates.
