if an unshielded sample of radioactive material emits alpha particles, what effect will it have on a person sitting in the next room? (assume the wall between rooms is composed of concrete.) none, because the wall will block the radiation. the radiation will travel through the persons body. none, because the radiation will bounce off the persons body. the radiation will be totally absorbed by the persons body.

Answer

Answer:

None, because the wall will block the radiation.

Explanation:

Step1: Understand alpha - particle properties

Alpha particles are relatively large and have low penetration power.

Step2: Consider the wall material

Concrete is a dense material. Alpha particles can be easily stopped by a thin layer of material like concrete. So, they will not pass through the concrete - wall to affect the person in the next room.
