Question 5

In the context of radiation safety protocols for nuclear facilities, which type of radiation primarily necessitates the use of thick, high-density materials like lead or concrete for effective external shielding?

Accepted Answer

C. Gamma rays, which are high-energy photons with no charge or mass. — Gamma rays are high-energy electromagnetic radiation (photons) that are highly penetrating due to their lack of charge and mass. Effective shielding against external gamma radiation requires dense, thick materials like lead or concrete to absorb their energy. Alpha particles are easily stopped by paper, and beta particles by thin aluminum, while neutron shielding typically involves hydrogenous materials to slow them down.

Answer

A. Alpha particles, due to their large mass and high kinetic energy.

Answer

B. Beta particles, as they can travel several meters in air.

Answer

D. Neutrons, because they can induce radioactivity in other materials.
