I am very confused how x rays work. How does the radiation get into the camera?

You know – you can do it with light too!
Take a strong light bulb. Now place it like this:
Light bulb | transparent plastic sheet. |. a cup. | wall
You’ll see the shadow of the cup on the wall, but no shadow for plastic sheet, right?
Replace light bulb with source of X rays
Plastic sheet is muscles – they don’t ‘block’ x rays just like the plastic sheet doesn’t block light as it’s transparent
Cup is bones – bones block x rays
X ray you see at doc office is like the wall – it shows the shadow
