← ScienceWhich outcome results when a high-energy gamma photon strikes unstable iodine-131?
A)Increased rate of beta decay✓
B)Immediate alpha particle emission
C)Reduced overall atomic mass
D)Stable isotope transmutation occurs
💡 Explanation
Irradiating iodine-131 with gamma photons adds energy, exciting the nucleus and increasing the probability of radioactive decay by beta emission. It's acceleration of decay via photon absorption, because stimulated emission alters decay paths; therefore accelerated radioactive decay, rather than transmutation, is the outcome.
