This is a very difficult question to answer as it does not specify the type of radiation.
As different materials react differently to different types of radiation it is essential to know the type of radiation.
Theoreticaly any material, but thickness matters. Any material with a high density or a high atomic number would do - lead is used in hospitals
No uv rays do not go through metal -Cybil
It irritates the Eyes, throat, lungs. It can also harm plants and other living things and damage many materials. It absorbs UV-B or more energetic light, that would otherwise reach Earth's surface. UV-B damages DNA, passing through skin (or leaf structures) that is transparent to UV-B.
The optical center of the lens is a point on the axis of a lens is the point where any ray passing through this point, the incident part and the emergent part are parallel. It is important for the proper refraction of light.
You'd need an extremely large X-ray machine. In practice, the Earth is far too thick for X-rays to stand any chance whatsoever of passing through it. The fact that the core is mostly metal (which tends to be pretty opaque to X-rays) doesn't help.
Almost never. X rays do not have enough energy to damage skin tissue or any body tissue. You would have to go through thousands of x rays to have even the slightest chance.
The condenser adjusts the amount of light passing through the specimen.
Materials with high atomic numbers, such as lead, and dense substances like bone or metal, can block the passage of x-rays due to their ability to absorb and scatter the radiation. The level of attenuation depends on factors like the thickness and density of the material through which the x-rays are passing.

REFRACTION
X-rays are a radiation which is above communications radio waves and below gamma rays. It is a highly energetic radio wave which is why it is able to pass through some materials. It is not energetic enough to pass through highly dense materials such as lead.
It is very difficult to answer this question since it is based on a total misunderstanding of what actually happens. Light rays, when passing through a triangular prism DO bend towards the thicker part of the prism!
"crepuscular rays" is the technical term...
Opaque means not allowing light rays to pass through.
