-rays are high-energy electromagnetic radiations frequently emitted during radioactive transformatio — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

Gamma ($\gamma$) emission is considered a secondary radioactive process. When a parent nucleus emits an $\alpha$ or $\beta$ particle, the resulting daughter nucleus is often left in an excited, higher energy state. It sheds this excess energy by emitting $\gamma$ -ray photons to reach its ground state.
