← ScienceWhich risk increases when a transuranic alpha source encapsulation fails?
A)Recoil-induced interstitial lattice displacement✓
B)Increased neutron emission background
C)Spontaneous fission reaction probability
D)Elevated gamma radiation emission
💡 Explanation
Alpha decay causes a nucleus to emit an alpha particle and recoil. The recoil causes significant lattice atom displacement because conservation of momentum transfers energy to the daughter nucleus; therefore, increased displacement results, rather than fission that requires achieving critical mass.
