Question

In the context of radioactive materials, what type of radiation is emitted from a rock and reduced when wrapped in foil?

A) Alpha radiation
B) Beta radiation
C) Gamma radiation
D) X-ray radiation

Answer 1

Alpha radiation is emitted from a rock and is reduced when wrapped in foil. Alpha radiation consists of two protons and two neutrons, symbolized by α. It has low penetration power and can be stopped by a sheet of paper.

Step-by-step explanation:

The type of radiation emitted from a rock and reduced when wrapped in foil is alpha radiation. Alpha radiation is composed of two protons and two neutrons, and it is symbolized by the Greek letter α. It has a low penetration power and can be stopped by a sheet of paper. Wrapping the rock in foil provides a barrier that blocks the alpha particles from escaping.
