X-rays are a type of radiation. They're similar sources of energy to light. However, light has a much lower frequency than X-rays and is absorbed by your skin. X-rays have a higher frequency and pass through the human body.
As X-rays pass through your body, energy particles called photons are absorbed at different rates. This pattern shows up on the X-ray images.
The parts of your body made up of dense material, such as bone, show up as clear white areas on an X-ray image. The softer parts, such as your heart and lungs, show up as darker areas. NHS Choices provides some useful information on what to expect when attending for an X-ray.
The Imaging department provides a number of X-ray services within North Bristol NHS Trust in both the Hospital and Community setting.
