x-rays cannot penetrate metals. Metals reflect the rays.

They cannot see through metals, generally.

As Firefox88 say, density is the keyword, along with the thickness and the material in self.

Although the industry uses X rays to check solid metal pieces are really solid, without fails inside, they cannot "see" the fails: the machine or the film only show that the metal is more or minus thick. If you cover something with a sheet of aluminum, for example, and pass it through a X ray machine, you will see the shape of the sheet and only the objects inside densest that the aluminum. If you use lead, you won't see nothing. That's why those heavy lead aprons in labs. And you can forget those "X ray glasses".

Moral: don't cover your air bound suitcase with lead.

The reason it's potentially dangerous to be exposed to x-rays is that they can mutate DNA, possibly causing cancer and reproductive problems. If your daughter passed through the x-ray machine, she has been exposed to some of this radiation, I'm sure. However, people get radiation in the everyday environment and our bodies have the ability to fight this off to some degree. It probably won't harm her too much if this only happened once. But you should avoid unnecessary exposure.

It all depends on how dense the object is. Things like quarters in a childs stomach cannot be seen through, which is why they stand out. Same things with bones. They are more dense than flesh, so you can see them more clearly.
