What is the primary characteristic of gamma rays compared to other forms of radiation?

• A. Their ability to ionize matter
• B. Their speed of travel
• C. Their ability to penetrate materials
• D. Their charge

Answer: (C)

Gamma rays are a type of electromagnetic radiation that possess a very high penetrating power compared to other forms of radiation, such as alpha particles and beta particles. This characteristic is due to their lack of mass and electric charge, allowing them to pass through matter with significant ease. While gamma rays can ionize matter, this ability is not as pronounced as that of alpha particles, which are more effective at ionization due to their mass and charge. The speed of gamma rays is constant, as all electromagnetic radiation travels at the speed of light when in a vacuum, so it is not a distinguishing feature. Gamma rays do not carry any electromagnetic charge, unlike alpha and beta radiation, which have positive and negative charges respectively. Thus, their primary characteristic is their high penetrating ability, making them a critical factor in radiation safety evaluations and protective measures.
