Which safety risk increases within positron emission tomography (PET) imaging when using short-lived isotopes?

💡 Explanation

Significant Bremsstrahlung exposure increases when short-lived postitron-emitting isotopes are used because beta decay produces high-energy positrons that decelerate within tissues. Therefore, Bremsstrahlung production increases, rather than pair production which arises from gamma rays instead of beta particles.
