← ScienceWhich consequence results upon exceeding the curium-242 decay threshold?
A)Increased neutron emission✓
B)Elevated risk of alpha decay
C)Onset of beta decay event
D)Enhanced gamma-ray production
💡 Explanation
Increased neutron emission occurs because spontaneous fission becomes dominant via quantum tunneling; therefore, additional neutrons eject suddenly, rather than alpha particles, because electrostatic repulsion forces are then secondary.
