Question

which type of radiation do people try to protect themselves from by wearing protective clothing that is made of aluminum?
o alpha radiation
o beta radiation
o gamma radiation
o photon radiation

Explanation:

Alpha radiation can be stopped by a sheet of paper or thin layers of materials like aluminum. Beta radiation requires a few - millimeters - thick layer of aluminum to be stopped. Gamma radiation needs thick layers of lead or concrete. Photon radiation is a general term and not the main type we consider here in this context. Since the question asks about protection with aluminum, it is mainly for beta radiation as alpha can be stopped by very thin materials and gamma needs much thicker and different materials.

Answer:

beta radiation
