What characteristic does gamma radiation possess?

Gamma radiation possesses the characteristic of having no charge. This is a fundamental property of gamma rays, which are a form of electromagnetic radiation, similar to X-rays but with higher energy. Because gamma rays are uncharged, they can penetrate materials much more effectively than charged particles, such as alpha or beta particles. This ability to traverse materials with minimal interaction is crucial in various applications, including medical imaging and radiation therapy.

The lack of charge also means that gamma radiation does not interact with electromagnetic fields, which allows it to travel long distances through various media without being deflected. This property makes it an important consideration for radiological safety and shielding, as specialized materials are required to effectively reduce exposure to gamma radiation.

In contrast, options that mention large mass, high charge, or slow movement do not accurately reflect the nature of gamma radiation, which is inherently massless and charge-free, and travels at the speed of light. These attributes contribute significantly to its behavior and effects in radiological contexts.
