Vedclass · Answer

(B) It is a fundamental principle of nuclear chemistry that the emission of an $\alpha$-particle or a $\beta$-particle leaves the daughter nucleus in an excited state. To return to the ground state,the nucleus releases the excess energy in the form of $\gamma$-rays. Therefore,$\gamma$-rays are always emitted following the emission of $\alpha$ or $\beta$ particles. It is impossible for a radioisotope to emit $\gamma$-rays alone without a preceding $\alpha$ or $\beta$ decay process.
