Gamma radiation is a form of electromagnetic radiation that possesses a high level of energy. One of its defining characteristics is its ability to penetrate various materials, including biological tissues. When gamma rays interact with the human body, they can either pass completely through it or be absorbed by tissues. This ability to penetrate means that gamma radiation can affect internal structures and organs, not just surface tissues.

Unlike alpha and beta radiation, which have more limited penetration abilities, gamma radiation can travel through many types of matter due to its high energy and short wavelengths. While some materials can provide effective shielding against gamma radiation—such as lead or concrete—there is no material that can shield it completely at all energy levels. This makes it significant in medical and industrial environments, as well as in radioactive contamination situations, where both external and internal effects on the body need to be considered.

In contrast, other options inaccurately represent the properties of gamma radiation, such as suggesting that it can be fully shielded by any material or that it only affects external tissues.
