How do x-rays work?

X-rays are like light just more energetic so they can pass through more. Our bones absorb the x-rays letting us see them.

That is, when a doctor scans your bones, what is happening?

Use a very small amount of radioactive substance to find a defect in your bones. A trained professional injects tracers in your bones then uses a special camera to take a picture of the bones.
