Which risk increases when a cobalt-60 source's encapsulation fails?

💡 Explanation

Increased external gamma radiation hazard rises because the lack of shielding from the encapsulation allows more gamma photons to escape, exposing more individuals; therefore, external radiation increases, rather than alpha/beta affecting materials within.
