← ScienceWhich consequence results when alpha decay in Uranium-238 dominates?
A)Helium accumulation within the crystal✓
B)Increased neutron emission efficiency
C)Protactinium-234 beta decay prevalence
D)Suppressed spontaneous fission probability
💡 Explanation
Alpha decay involves quantum tunneling through a potential barrier, causing Helium-4 nuclei emission. Helium is then trapped in uranium crystal structures because decay increases helium concentrations rather than altering nuclear behavior, therefore helium increases, not other processes that influence different decay chains.
