Which outcome occurs when a Cesium-137 source nears depletion?

💡 Explanation

Gamma emission rate decreases because radioactive decay follows first-order kinetics; therefore fewer Cesium-137 atoms remain to undergo beta decay followed by gamma emission, rather than changes to inherent decay parameters or emission pathways.
