What is a characteristic of gamma radiation?

Gamma radiation is a form of electromagnetic radiation that is similar to X-rays but with higher energy. One of its defining characteristics is that it has no mass and carries no electrical charge. This property enables gamma rays to pass through matter more readily than other types of radiation, such as alpha or beta particles, which do possess mass and charge.

The absence of mass means gamma radiation cannot interact with matter in the same way that particles with mass can, leading to its penetrating ability. This is also why it requires dense materials like lead or several centimeters of concrete for effective shielding, as lighter materials, such as paper or plastic, are inadequate for protection against gamma rays. Understanding this characteristic is critical for radiation safety and protection protocols in environments where gamma radiation is present.
