← ScienceWhich consequence results when U-235 undergoes neutron-induced fission?
A)Chain reaction criticality escalation occurs✓
B)Alpha emission increases sharply
C)Beta decay rate decreases rapidly
D)Gamma radiation immediately ceases
💡 Explanation
Runaway criticality happens because fission emits neutrons, which then stimulate further fission events by the mechanism of nuclear chain reaction; therefore, escalation occurs rather than stabilization or other decay changes, and no external constraints halt the rising reaction rate.
