← ScienceWhich outcome results when exceeding curium-242's critical mass?
A)Rapid release energetic neutrons✓
B)Stable alpha particle emission
C)Increased rate of beta decay
D)Spontaneous isotopic enrichment
💡 Explanation
A chain reaction initiates because neutron-induced fission causes exponential neutron propagation; therefore a rapid release of energetic neutrons occurs, rather than alpha or beta decay, which are slower processes independent of critical mass.
