← ScienceWhich outcome accelerates plutonium-239's breakdown in nuclear waste repositories?
A)Elevated temperatures promote alpha decay✓
B)Neutron bombardment induces beta decay
C)Increased pressure inhibits electron capture
D)Chemical reactions accelerate positron emission
💡 Explanation
Elevated temperature accelerates alpha decay because increased thermal energy enhances quantum tunneling through the potential barrier, therefore the rate of fission increases rather than beta decay which usually requires a different trigger.
