(D) When a radioactive substance is inside the human body,the radiation emitted is absorbed by the surrounding tissues. $\alpha$-particles have the highest ionizing power among the given options. Because they are heavy and carry a $+2$ charge,they cause intense localized damage to biological cells and tissues when emitted internally. Therefore,$\alpha$-emitters are the most harmful when ingested or inhaled.
