Can bases used as radiation shield?
If you think to hydroxides - no.
Lead, Pb, will stop almost all types of radiation.
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.

Nuclear transmission is that measurement of amount of radiation found inside of a shield versus the outside. The transmission is the amount of radiation that is received by passing through the protective shield.
Thick concrete walls will shield most radiation.
Yes it does. It acts as a shield.
protected earth from radiation.
Ozone shields against incoming UV radiation
No. You can shield it, to stop radiation from continuing out, or you can wait for an eternity for most of the radiation to die out by itself, but that's about it.
Molecules act as a shield to ultraviolet rays. These molecules are ozone.
* Alpha radiation can be stopped by a sheet of card * Beta radiation can be stopped be a few inches of aluminium * Gamma radiation can be stopped by several inches of lead or many feet of concrete.
Alpha radiation is the easiest to shield, only requiring a few inches of air or a sheet of paper. This is because alpha has a mass of four amu and a charge of +2, making it interact with nearly everything.
Cell Phone Radiation Protection Cell Phones emit Electromagnetic Frequencies (EMIs), cell phone radiation. Long term exposure to high levels of cell phone radiation can harm human cells and tissues, causing serious health problems such as tumors, organ failures, cancer, etc. SAR Shield is the only engineered, tested, and approved (FCC) device available in the U.S. that will reduce cell phone radiation while your cell phone is in use so this is a cell phone radiation… Read More
A decent sized dictionary.
The type of radiation that is easiest to shield are alpha particles. They are also the least harmful. Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus.
Melanin, why ? Because melanin acts as a protective biological shield against ultraviolet radiation.
It would take several inches of solid lead to prevent gamma radiation from reaching you.
It has no atmosphere and nothing to shield it from solar radiation.
No. But you can shield the emitted readiations by absorbers. A well-known shield used for this prupose is lead. If you get your teeth x-rayed at the dentist, you know what this looks like.
No. There is no atmosphere, no liquid water, and no magnetic field to shield against radiation.
the ozone layer
by using an iron shield
The indian layer
As with strong acides, strong bases can damage your eyes and skin. A face shield and/or goggles, gloves and a lab apron.
No, oxygen does not. Ozone, an allotrope of oxygen shields us.
Radium is radioactive and lead is a good radiation shield.
It can kill you, but its easy to shield ... a thin layer of foil will block it completely.
Since ultraviolet radiation from the sun does have to travel through outer space in order to reach the Earth, you could say that it comes from space, and therefore the ozone layer which protects against solar ultraviolet radiation is a kind of space shield.
Hydrogen is an excellent absorber of neutrons and gamma radiation. In water, it is *very* common as a shielding material. Cobalt-59 is used as a neutron absorber for some nuclear reactors (control rods), and makes a radioactive material useful in industry and medicine (Co-60). Zirconium can accept many neutrons before becoming radioactive itself. It is commonly used to package materials used in the nuclear industry. Uranium-238 is an excellent shield for gamma radiation sources, requiring… Read More
On Earth the atmosphere blocks out a lot of the radiation that is whizzing about in space, radiation that would otherwise be able to hurt us. Astronauts, being outside the atmosphere, can need something else to protect them from that radiation.
The Ozone shield protects the earth from much of the Suns harmful radiation.
Uranium 238 can be used in weapons, armors, as a nuclear fuel in breeder reactors, as radiation shield, etc.
Alpha radiation is used in a few practical applications, occassionally even to make use of it's harmful effects. Alpha radiation is often used as a power source for space probes and artificial pacemakers, a safe one at that as alpha radiation is easier to shield against than other radiation types. It can also be used to treat cancerous tumours in the body in a process called 'unsealed source radiatherapy', it can be risky to use… Read More
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.
It depends where you go
Production of pure chemicals and medicines. Any place where the contaminants in water are intolerable. Deionized water is usually good enough for a radiation shield...
3 most important thing to stay safe with radiation Time: Minimal time to complete the work with radiation to minimized radiation hazard Distance: Keep distance from radiation source where possible Shielding: Use radiation shield and stay behind, use lead coated glove and suit when it need to come in contact.
That question is also asked in our take home test at biology. :) Melanin, why ? Because melanin acts as a protective biological shield against ultraviolet radiation.
It is called a radiation containment shield. Related Information: It would normally be placed around the outside of the sealed, steel pressure vessel that contains the reactor core. This is because the core temperature can easily exceed the melting point of lead which would not only defeat its purpose, but cause a contamination problem as well. Lead does an excellent job of absorbing gamma radiation and migrating neutrons. So it is used extensively to shield… Read More
Neutron radiation is as dangerous as any other ionizing radiation, if not more dangerous,as by some sources, it can be as many as ten times more dangerous as other ionizing radiation. It is not directly ionizing radiation, since neutrons do not hold electric charge, but they interact (collide) with nuclei in it's path, creating isotopes, most of the time non-sable, radioactive isotopes. That is why neutron radiation induces a secondary radiation in the material it… Read More
the acids penetrate the food and act as a preserving shield
The atmospheric shield which protects Earth from the radiation of the sun is the Earth's own magnetic field. Also, the ozone layer (O3 particles in the stratosphere) help to filter Ultraviolet light.
Shielding- Reducing the ionization radiation reaching one region of space to the other by using a shield or other devise
You have to wear a shield if you are working or having cobalt therapy.Only the affected area is exposed.
Because there's no way to shield yourself from all of it ... and it exists everywhere.
solid and at least three feet thick to shield from solar radiation
Most of the ozone absorbs the UV rays. It acts as a shield to the earth.
Along with light and heat, the sun sends out large amounts of radiation- enough to fry our little planet and leave a scorched ball of dust behind. However, our magnetic field creates a type of shield that averts the majority of this radiation. Towards the poles, the 'shield' is less effective, and smaller amounts of the more energetic radiation particles pass through. When these enter the atmosphere, they leave bright trails behind them, which we… Read More
The problem is not that gamma radiation is harmful per se. Indeed, all radiation is harmful in high enough dosages or for long enough periods. The problem is that unlike alpha and beta radiation, which are particulate (helium atoms and electrons, respectively), gamma radiation is in the form of rays (photon rays, to be specific) and are such much more difficult to properly shield and contain.
The shield protects life on earth from deadly radiation by deflecting the radiation away from the atmosphere. It also prevents the atmosphere from being blown away by the solar wind.
