Most alpha particles can be stopped by a thin piece of paper. Even the dead cells in the outer layer of human skin provide adequate shielding because alpha particles can’t penetrate it.
Beta particles are more penetrating than alpha particles. Beta shields are usually made of aluminum, brass, plastic, or other materials of low atomic number to reduce the production of bremsstrahlung radiation.
Lead is a common shielding material for gamma radiation because it has a high density, is inexpensive, and is relatively easy to work with
