Question

Alpha particles have lower penetration power than beta particles.

• A. True
• B. False

Answer 1

The correct option is A True

Alpha particles are a type of radiation that do not travel very far, do not pass through anything very thick, and can generally be absorbed or stopped by an inch or less (1 - 2 centimeters) of air or a thin piece of tissue. Beta particles are electrons emitted from an atom. In air, beta particles can travel a few hundred times farther than alpha particles, up to six feet (two meters) or more.
