Are You Curious About How X-Ray Images Are Shown?
When a doctor needs to see the inside of your body, they use an x-ray exam to take pictures of what is inside of you. X-ray images are usually used to look at the condition of your teeth and bones 🦴.
Solid things like your bones will show up white while squishy materials like your muscles will look gray. The air in your lungs will look black. X-ray can be dangerous to a certain level, but you want to find out how X-rays look like (in a safe way), fret not! We are here to help you.

Light box with torch light, and dinosaur bones
Step by Step
- Cover the box with black construction paper. Leave the lid uncovered.
- Place the torch light inside the box and close it. This is your light box. You can also cut a hole on the surface of the box and cover it with transparency film after you have placed the torch light in the box.
- Print out the x-ray images on the carbon paper.
- Bring your light box to a dark room and put the x-ray image on top of the light box. Watch the magic happen! Option: You can simply hold the printed x-ray image against the window to see how your x-ray image turns out.

What do you observe?
Dense body parts, such as bones, block the passage of the X-ray beam through the body. These look white on the X-ray image. Softer body tissues, such as the skin and muscles, allow the X-ray beams to pass through them. They look darker on the image. Now that you have learnt about how x-ray imaging works, you can try to make your own!
