What does x-radiation NOT have?

X-radiation does not possess mass, which is a fundamental characteristic of matter. This absence of mass is crucial to the nature of x-rays as electromagnetic radiation. Being part of the electromagnetic spectrum, x-radiation consists of photons, which are packets of energy that do not have mass. While x-rays travel at the incredible speed of light and can interact with matter, these interactions do not involve a mass attribute as seen in traditional particles like protons or neutrons.

Understanding that x-radiation is comprised of massless photons helps clarify its behavior in medical imaging and other applications. For example, in radiography, the lack of mass allows x-rays to penetrate tissues and create images without the physical weight of particles affecting the body's structure. This characteristic is essential for safe and effective use in dental practices and other medical fields.
