Which type of radiation do people try to protect themselves from by wearing protective clothing that is made of aluminum?

Beta radiation consists of fast-moving particles that can penetrate skin, but a thin layer of aluminum can stop many beta particles. Alpha radiation is stopped by paper or the outer layer of skin, while gamma and other photon radiation generally require much denser shielding. Therefore, aluminum protective clothing is used against beta radiation.
