Final answer:
Gamma radiation requires lead shielding for protection.
Step-by-step explanation:
The type of radiation that requires lead shielding for your protection is gamma radiation (D).
Gamma radiation is a type of electromagnetic radiation that consists of high-energy photons. It is highly penetrating and can pass through most materials, but certain dense, high atomic number elements like lead can effectively attenuate gamma radiation.
In contrast, alpha particles (A) and beta particles (B) have lower penetration abilities and require different types of shielding. Alpha particles can be stopped by a thin barrier, such as a sheet of paper, while beta particles can be stopped by a thin layer of metal.
