Which statement describes gamma radiation?

• A. Gamma radiation consists of two protons.
• B. Gamma radiation contains charged particles, either electrons or positrons.
• C. Gamma radiation is a type of electromagnetic radiation.
• D. Gamma radiation consists of stable particles.

Answer: (C)

Gamma radiation is energy carried by photons in the gamma region of the electromagnetic spectrum. These photons have no mass and no electric charge, and they travel at the speed of light. They are emitted when a nucleus transitions from a higher to a lower energy state, not as particles like protons or electrons. This makes the statement that gamma radiation is a type of electromagnetic radiation the correct description. The other options describe particles or charged components, which gamma rays are not.
