X-rays will "expose" X-ray film. That's how imaging (medical or otherwise) is accomplished using X-rays.

We know that X-rays are high energy electromagnetic rays, and they are a form of penetrating radiation. X-ray film is photographic film, and this is film which will undergo chemical changes when exposed to light. X-rays and visible (optical) light are both electromagnetic radiation, and exposing film to X-rays will "leave an image" on the film, depending on the conditions of exposure.

When using X-rays, which have a great ability to penetrate different materials, we enclose the film in a "film pack" which is positioned in such a way that it is "behind" the subject or object to be X-rayed. The source emits the X-rays, they pass through the object under scrutiny, and through the film. (The film is shielded from optical light by the packaging, but the X-rays pass right through it.) The film, which has been exposed to the X-rays, is then developed to yield images.

We might note that modern imaging is moving to a "digital" X-ray with the elimination of the film and the substitution of an X-ray sensitive "grid" or "screen" behind the subject. This makes images quickly available (there is no delay as with developing film) and allows for immediate digital storage (with no "conversion" from film to digital format).

What is is used as a shield to protect people from radioactive substances?

Lead is most commonly used for protecting people from radioactive substances. For example, if you go to the dentist and they give you an X-ray of your teeth, they will usually give you a lead bib to protect you from the radiation produced by the X-ray. However, carbon (graphite usually) can also be used to shield, but whereas a plate of lead may work it would take a brick of graphite.
