For example, adding materials like boron carbide boosts its ability to block neutrons, while heavy aggregates like barite and magnetite help shield against photons (a form of gamma radiation).

This is done by choosing isotopes that: Water supplies can be contaminated with a gamma-emitting ... blocked with suitable shielding Once an object is contaminated, the radiation cannot be blocked ...
