List the three common forms of radioactive emission by penetrating ability from least to most.

Question

Quizplus · Accepted Answer

Alpha particles have the least penetrating ability, followed by beta particles, and gamma rays have the most penetrating ability. This is because alpha particles are large and heavy, so they can be blocked by a sheet of paper or even the outer layers of skin. Beta particles are smaller and faster, so they can penetrate through thin materials, but can be blocked by a few millimeters of aluminum. Gamma rays are electromagnetic radiation and have the highest energy and smallest wavelength, so they can penetrate through thick materials, including lead and concrete.
