Lead is the most commonly used metal as shielding in radiation. Lead is economical and has got very high atomic number. This very high atomic number makes it suitable as a shielding agent in radiation, probably. You can use other metals like steel also. Probably with less efficacy.

How can we protect ourselves from ultraviolet rays and gamma rays and X-rays?
Appropriate clothing or sunblock provide protection from ultraviolet (UV) rays when one must be out in the sun. Dense materials like lead can be used as shielding from X-rays if a sufficient thickness is in place. In any case, we don't want anyone too close to the source. We also know that dense materials can provide shielding from gamma rays, but even more must be used as gamma rays have more energy than X-rays. UV rays can be stopped more easily than the other two radiation types, but more shielding is better for protection from the latter two radiation types. Also, the less time anyone is exposed to radiation, the better.
How is chain reaction controlled in a nuclear power plant?
The radiation shield used on a large scale for fixed shielding is concrete. This is effective because the large mass of concrete absorbs gamma radiation well, and as it contains a lot of water molecules it also stops neutrons from penetrating.
In what ways is radiation useful?
Radiation is used every day for medical treatment. Radiation treatment is an accepted form of therapy for some forms of carcinoma. We also use it in medical imaging and in other forms of patient testing and evaluation. There is a lot of other biological investigation that involves the use of radiation emitted from nuclear materials, too. The so-called radioactive tracers help us track and document the processes of life. Industrial uses abound. We use radiation to sterilize things. It works very well, and it's more practical and cost-effective to have a radioactive source rather than use electricy to generate ionizing radiation. We also use "chunks" of radioactive material as a radiation source for portable X-rays. You wouldn't believe all the stuff we X-ray in the world of industry. Pipe welds are just one thing. You would expect that physicists are still investigating various aspects of nuclear behavior using radiation, and they are. There are still other uses of radiation, but note that there are a couple of basic "flavors" of radiation: electromagnetic (like X-rays and gamma rays) and particulate (like beta particles, protons and neutrons). Just wanted you to be aware of that. As an example, neutron flux in the core of an operating nuclear reactor is used in lots of applications to synthesize materials, and these materials will emit either kind of radiation depending on what we make and what we want. That's were a lot of nuclear materials come from. We also are seeing an increase in the use of the cyclotron, a particle accelerator. It is applied to both systhesize materials and also to be used in imaging and as a new treatment option in radiation therapy. It's a new frontier.
What does not permit the passage of x-rays?
lead. that's why it is used in x-ray shielding for x-ray technicians (amongst other things)
Can magnetism be shielded?
Mu-metal does a pretty good job for smaller fields, but completely shielding something from a magnetic field with a high field strength is not doable. Giron is supposed to be pretty good, and so is MetGlas, but they cannot stop (deflect) all the field lines from a strong field. Highly permeable material is the best shielding. Magnetic lines of force like to travel through permeable materials. That's what permeable means - an easy (easier) route than through space, air, whatever, for magnetic lines of force. What these shielding materials are doing is giving the magnetic lines of force a place to travel other than through space or through whatever is being shielded. The field still exists, but it's concentrated inside the shielding. And the lines of force will reappear from inside the shielding material at its edges. What else would one expect? The shielding can't make the lines of force disappear. As it re-routes them, it means that it has to re-release them somehow. Field density at the edges of shielding will be high. The field is collected for re-routing and distributed back into space after re-routing at a shield's edges. The materials cited are passive shields. Active shields can be constructed, but they are most challenging to engineer. Active magnetic shielding is used in the machinery for magnetic resonance imaging (MRI), and it is an active winding that is driven by an electronics package so that it "cancels out" fields outside the main coil. It's a headache and a half to design and implement active shielding. No shielding can block, stop, or re-route all the magnetic field lines from a magnetic source. Some lines of force will not be re-routed through the shielding and will appear on the other side of it.
What is lead nitrate used for?
radiation shielding
Why the distance shielding for Gamma ray and Emitted Neturon is different?
Gamma rays are a form of electromagnetic radiation, and are absorbed by heavy materials such as lead which is often used for such shielding. Neutrons are uncharged particles which can pass through many materials, but are strongly absorbed by for example cadmium and boron, which are said to have a high capture cross section for neutrons. Therefore effective neutron shields can use such materials.

What uses does Heavyweight concrete have other than radiation shielding?
It is also used for bridge counter-weight and for weighting down underwater pipelines etc.....Dan
Is titanium a good radiation shielding material?
Ilmenite ( FeTiO3) is a good aggregate type to be used in the heavy dense concrete for a nuclear plant shielding. Dr. Medhat, HBRC, Egypt

How is radiation used to help the environment?
Radiation is used in removing toxic materials in the environment like some hazardous gasses in the air. Radiation is also used in some medical treatments.
How many uses does tungsten have?
Hundreds. It is used as filaments for light bulbs, combined with carbide to make really tough cutting tools, and as shielding for nuclear radiation.
What is the shielding in computer graphics?
shielding is used to decouple the effects of incident illumination
An isotope that's element is used in nuclear shields?
Depleted uranium, which is mostly Uranium-238 is used for shielding gamma radiation. Though it is radioactive, it has a very long half life, and is very effective against gamma radiation. The result is that it makes a pretty good shield.
For a solar collector to collect solar radiation what materials can be used?
Simple materials can be used like black plastic or metal pipe. You want materials that will absorb heat and transmit that heat to the liquid.
How different materials can be used to decrease radiation?
These materials are for impenetrable for gamma rays: lead, materials with lead (concrete, glass), materials containing boron or compounds, stainless steel etc.
