Lead. When you go to the dentist you wear a lead drape when the x-rays are taken.

Any type of metal can block an x-ray. The most common being lead. In hospitals and dr.s offices, when they take x-rays the nurse will always ask you to remove any type of metal objects like belt buckles, earrings, necklaces, eyeglasses. The metal in these objects will leave a clear spot on the x-ray film.

Anything that has a high enough density, or that there is is enough of, will block X ray. Bones are denser than flesh, that is why they show up on X ray; because they blocked it and not the flesh.
A thin layer of lead, or gold, or platinum (lead is used because it is cheaper, surprise surprise) or a thicker layer of a lighter material, like iron or copper, or a somewhat thick layer of lighter still material, like aluminum, will block X- ray.
You fillings will show up of a dental X-ray, and a swallowed coin will show up in an abdominal X-ray, and barium salt will show up of in an X-ray (used to image the digestive system) because these objects stop X-ray more readily than flesh.

At the dentist office they give you a lead apron to protect you, so lead would block x-ray, most common larger objects (walls, for example) block the x-ray so not everyone in the building is exposed....

Lead can block X-rays. I suppose other dense metals can as well, but it's lead that is used at dentists' offices and doctors' offices when X-rays are taken on only one body part & they want to protect the rest of the body.

Nothing can block an X-ray. Lead absorbs X-rays, most metals deflect X-rays. Now ask, what is an X-ray? I'd like to see what people think.

Planets are fairly good protection against X-rays but there are a few other things that are easier to carry around like lead, steel and concrete. Lead is simply the best as it doesn't require the same thickness as the others to give you suitable protection

Heavy metals can disrupt it, and most heavy fabrics can *slightly* disrupt it, like denim--this is if you're asking about the type of X-rays used in doctors' offices for broken bones and such. I don't know about high-powered ones.

X-rays are high energy radiation. It is shielded by high density materials. Lead is commonly used. Tungsten will work better but is very expensive. Steel will also work but not as well as lead.
