A circuit breaker box (or fuse box) in the bedroom, living room, kitchen, or other living space can be a real problem.
If you are handy, you can use the magnetic shielding materials listed below to make your own hinged shield.
Another alternative is to mount the Giron directly on the wall and cover it with these attractive interior window shutters. GIRON Magnetic Shielding Film, which does not contain Nickel, is unlike any other magnetic shielding material available on the market today.
Suitable for small shields on magnets, motors, speakers and appliances such as refrigerators, vacuum cleaners etc.
We have teamed with the design and engineering division of the Giron manufacturer to offer start-to-finish magnetic shielding solutions for residential, commercial, and industrial buildings. Enjoy the confidence of an experienced team to obtain excellent results, lowest cost, and on-time delivery. Used for years in industry to shield delicate electronic components from EMFs, this 80% Nickel alloy magnetic shielding foil is now available at affordable prices for home and office use. Because we offer so many different matrials, of different widths, the easiest way to order rolled goods is by specifying how long the piece of material will be. The amount of shielding that you will achieve depends on many factors, including the size and shape of the shield.
When using a flat shield on a wall, floor, or ceiling to shield a source of field that is close to the shield (within 8 inches), plan to cover an area that extends at least to the 2 mG line.
1- Using your gaussmeter, slide along the surface of the wall to locate the hot spot to be shielded.
2- Now slide the gaussmeter to the right, to the left, up, and down to identify how far you must shield to get to the 2 mG line. Make sure to check for additional sources of magnetic field (lights, wiring, appliances and so on), that may be located inside adjacent walls, floor, ceiling or within the same room.
Click here for a short instructional video on doing a magnetic field survery for shield design. While the special alloys in Magnetic Shielding Foil, Mag-Stop Plates, Joint Shield, and Metglas, exhibit high magnetic permeability, there are many factors which affect the amount of magnetic shielding you will achieve by using these materials. Because we have no control over many of these factors, we cannot and do not guarantee any specific shielding performance for a specific application of these materials. 3] In general, you will extend the shield at least 2 feet beyond the size of the circuit box (or other fairly concentrated source), in all directions. 5] Also remember that you will achieve the greatest % reduction up close to the center of the shield (where the field is strongest anyway). In the end, some experimenting is often necessary to ensure proper shield thickness and placement. Joint-Shield can also be used by itself as an excellent magnetic shielding material when a 4" width and adhesive backing is desirable (wrap it around wiring and conduit, speaker magnets, even small appliances like shavers and hair dryers!). Combining high performance nanocrystalline magnetic shielding alloy sandwiched between layers of clear PET to achieve good performance and easy handling.
First line of defense for shielding strong magnetic fields from magnets, speakers, small transformers and motors. Better: One or more layers of MagnetShield (closest to the source of field), followed by one or more layers of a high permeability material such as Joint-Shield or MagStop Plate. For shielding jobs where you don’t need a high attenuation, this unique material is just the ticket.
Attention pacemaker wearers, welders and anyone wanting to shield their upper body from magnetic fields! Made with 10mm diameter, shiny galvanized, 16g round mild steel rings which are butted closed.
At last, we are proud to offer wiring which actually reduces EMF emissions to extremely low levels.
The result is a high quality wire with the lowest possible EMF emissions (over 90% reduction compared to standard wire).
MµCord™ flexible “appliance cord style” for re-wiring lights and appliances, making extension cords, etc. Communication: Permanent dipoles contribute to electric polarization in chiral NMR spectra. Nuclear magnetic resonance spectroscopy is blind to chirality because the spectra of a molecule and its mirror image are identical unless the environment is chiral.

This site was developed to explain exactly what magnetic shielding is, what is permeability and how MuShield designs, creates and engineers custom magnetic shielding.
Hard X-rays can penetrate solid objects, and their largest use is to take images of the inside of objects in diagnostic radiography and crystallography. The roentgen (R) is an obsolete traditional unit of exposure, which represented the amount of radiation required to create one electrostatic unit of charge of each polarity in one cubic centimeter of dry air. The rad is the (obsolete) corresponding traditional unit, equal to 10 millijoules of energy deposited per kilogram. The sievert (Sv) is the SI unit of equivalent dose, which for X-rays is numerically equal to the gray (Gy).
X-rays are generated by an X-ray tube, a vacuum tube that uses a high voltage to accelerate the electrons released by a hot cathode to a high velocity. In crystallography, a copper target is most common, with cobalt often being used when fluorescence from iron content in the sample might otherwise present a problem.
X-ray fluorescence: If the electron has enough energy it can knock an orbital electron out of the inner electron shell of a metal atom, and as a result electrons from higher energy levels then fill up the vacancy and X-ray photons are emitted.
So the resulting output of a tube consists of a continuous bremsstrahlung spectrum falling off to zero at the tube voltage, plus several spikes at the characteristic lines.


In medical diagnostic applications, the low energy (soft) X-rays are unwanted, since they are totally absorbed by the body, increasing the dose.
To generate an image of the cardiovascular system, including the arteries and veins (angiography) an initial image is taken of the anatomical region of interest.
A specialized source of X-rays which is becoming widely used in research is synchrotron radiation, which is generated by particle accelerators. The most commonly known methods are photographic plates, photographic film in cassettes, and rare earth screens. Before the advent of the digital computer and before invention of digital imaging, photographic plates were used to produce most radiographic images.
Since photographic plates are sensitive to X-rays, they provide a means of recording the image, but they also required much X-ray exposure (to the patient), hence intensifying screens were devised.
Areas where the X-rays strike darken when developed, causing bones to appear lighter than the surrounding soft tissue. Contrast compounds containing barium or iodine, which are radiopaque, can be ingested in the gastrointestinal tract (barium) or injected in the artery or veins to highlight these vessels.
An increasingly common method is the use of photostimulated luminescence (PSL), pioneered by Fuji in the 1980s. The PSP plate can be reused, and existing X-ray equipment requires no modification to use them. For many applications, counters are not sealed but are constantly fed with purified gas, thus reducing problems of contamination or gas aging. Some materials such as sodium iodide (NaI) can "convert" an X-ray photon to a visible photon; an electronic detector can be built by adding a photomultiplier. 2*3 magnetic white board for India large project2*3 magnetic white board for India large project   1. Magnetic MaterialFeatures:We order to do the different specification and the magnet shelf of the function, the surface magnetic force can attain a 14000 GS. Strong magnetic field emissions (depending on how much electric current is flowing) and electric field emissions can make the nearby area hazardous to occupy, especially for long periods. Suitable for high field strength applications requiring high saturation and good permeability, it is both thin and strong, and unlike Mu-metal™ it is very tolerant to bending or shaping without losing its shielding properties.
Cuts neatly with snips or sheet metal tools, and can be used either flat or molded into shapes for best performance.
The 30" wide "fully hydrogen annealed" plates offer the best shielding available (up to 10 times the shielding effectiveness of stress-annealed alloy) and should not be soldered, welded, or heated in any way. The list of such factors includes: size and shape of the source of the magnetic field, size and shape of the shielded area, seams in the shielding material, frequency of the magnetic field, distance from shield to source, orientation of shield to the source, thickness and heat treatment of shielding material, etc. Also, note that foils, ribbons and plates, once cut by us to your specifications, are not refundable. Remember to make measurements under various conditions, as the readings will change according to how much electric current is flowing at the time of the reading. This will influence the choice for thickness of the Mag-Stop Plate shield, or the number of layers used.
In other words, the field will be stronger at the edge of the shield as compared to having no shield at all. This occurs when the Earth's magnetic field (about 400 mG) interacts with a large shield, reducing its effectiveness, unless special "high saturation" (MagnetShield) shielding alloys are incorporated into the design. Joint-Shield can be shaped by hand, without the need for special tools, but watch the sharp edges.
Very light weight and flexible, easily trimmed with scissors this material will provide good high frequency magnetic shielding for moderate to low intensity fields below 1000 kHz. Strong magnetic fields are harder to shield because they tend to "saturate" the shielding material.
If you want to shield 2 adjacent magnets from eachother, each magnet should have its own shield. Only 0.010 inch thick, PaperSHIELD is flexible and can be easily cut with a scissors and shaped by hand into simple or very complex shapes. Replacing existing wire with MµCord is likely to be much less costly, more effective, and probably more convenient than shielding.
Simply cut wire to desired length and add a plug to one end, or plug one end and socket on the other.
However, precessing nuclear magnetic moments in chiral molecules in a strong magnetic field induce an electric polarization through the nuclear magnetic shielding polarizability.
This process produces an emission spectrum of X-ray frequencies, sometimes referred to as the spectral lines.
The intensity of the X-rays increases linearly with decreasing frequency, from zero at the energy of the incident electrons, the voltage on the X-ray tube.
A second image is then taken of the same region after iodinated contrast material has been injected into the blood vessels within this area. The contrast compounds have high atomic numbered elements in them that (like bone) essentially block the X-rays and hence the once hollow organ or vessel can be more readily seen. In modern hospitals a photostimulable phosphor plate (PSP plate) is used in place of the photographic plate.
Shielding is certainly possible, but the shield must not hamper quick and easy access to the controls inside the box.
It’s a picture (or poster) in a nice frame, with high performance Giron shielding material behind the picture.
We'll help you find the right solution, saving time, money, and creating satisfied customers! Now you can simply replace your Switch Plate or Outlet Cover with these custom shielded ones. So, for example, if you order 22 linear feet of a material, you will get a piece that is 22 feet long x the width of the material.
Hydrogen annealed plates have 2 small holes pre-drilled near one end which may be used for mounting.


Also, find out if there are other sources, such as wiring leading to the circuit box, nearby fluorescent lights, etc. Most would recommend that you achieve readings of 2.5 mG or less in areas where people will be spending a lot of time.
This is a generous .010" thick, fully hydrogen annealed magnetic shielding alloy with adhesive backing (rated 0 - 200°F) on one side. This 4" wide foil is a hefty .010" thick and has an exceptionally high magnetic saturation of 21400 Gauss and maximum permeability of 4000. High saturation and moderate permeability make this ideal for shielding weak magnets, or stronger magnets with many layers of shielding. Composed of individual metal links which give good flexibility and plenty of air circulation.
For example, if you don’t need the head covering, you could move those links to achieve more shoulder or heart coverage.
Such apparently paradoxical geometrical isotope effect (GIE) on RN···Be is revealed by the cooperative effect of two kinds of (1) primary covalent-bonded GIE and (2) secondary dihydrogen-bonded one. This effect is equal and opposite for a molecule and its mirror image but is small and has not yet been observed. The spectral lines generated depend on the target (anode) element used and thus are called characteristic lines. These two images are then digitally subtracted, leaving an image of only the iodinated contrast outlining the blood vessels. Photographic film largely replaced these plates, and it was used in X-ray laboratories to produce medical images. In the pursuit of a non-toxic contrast material, many types of high atomic number elements were evaluated. After the plate is X-rayed, excited electrons in the phosphor material remain "trapped" in "colour centres" in the crystal lattice until stimulated by a laser beam passed over the plate surface. Electrons accelerate toward the anode, in the process causing further ionization along their trajectory. Magnetic field reduction is 30 to 60% up close to the surface, depending on wire configuration. Can be formed into magnetic barriers on cellular phones, microwave ovens, doorbell transformers, VDTs, buried wiring, and more. Just right when you need to cut magnetic shielding materials including Giron, MagnetShield , and Magnetic Shielding Foil. Simply butt the Mag-Stop plates tightly together, and "tape" over the seam with Joint-Shield high permeabilty alloy. Tin plated for excellent corrosion resistance and better conductivity, it can be soldered or painted. This material is particularly suited for achieving precise levels of partial shielding as you can add exactly the right number of layers to achieve the desired result.
We have demonstrated that (1) the covalent bond lengths become shorter by heavier isotope-substitution and (2) the dihydrogen-bonded distance RX···Y becomes shorter by heavier Y and lighter X isotope-substitution due to the difference of electronic structure reflected by the nuclear distribution. It is shown that the permanent electric dipole moment of a chiral molecule is partially oriented through the antisymmetric part of the nuclear magnetic shielding tensor, causing the electric dipole to precess with the nuclear magnetic moment and producing a much larger temperature-dependent electric polarization with better prospects of detection. The radiologist or surgeon then compares the image obtained to normal anatomical images to determine if there is any damage or blockage of the vessel. In more recent years, computerized and digital radiography has been replacing photographic film in medical and dental applications, though film technology remains in widespread use in industrial radiography processes (e.g. For example, the first time the forefathers used contrast it was chalk, and was used on a cadaver's vessels.
This process, known as a Townsend avalanche, is detected as a sudden current, called a "count" or "event". With snug fitting shapes, get as much as 75% attenuation of the magnetic field with one thickness. This method offers much less bulk and better appearance than the old overlap technique and provides excellent shielding integrity.
When the film is developed, the parts of the image corresponding to higher X-ray exposure are dark, leaving a white shadow of bones on the film.
In our tests, a 2-foot section of Giron in a 24x36 inch frame provided 50-70% reduction of magnetic field. Works with AC or DC magnetic fields (0-1000 Hz), and will tolerate temperatures from 32° to 140°F.
Simple to use: just cut to desired length with a heavy scissors, peel the protective backing and press into place! Peel and stick adhesive on the other side permits easy and semi-permanent mounting almost anywhere. Photographic plates are mostly things of history, and their replacement, the "intensifying screen", is also fading into history. If you need a shield larger than what is suggested here, just contact us, we will be happy to assist you. Laminated with a 0.005 inch glass reinforced polypropylene tape which is UV sensitive, cover if installation is exposed to direct sunlight. The metal silver (formerly necessary to the radiographic & photographic industries) is a non-renewable resource. Thus it is beneficial that this is now being replaced by digital (DR) and computed (CR) technology.
Where photographic films required wet processing facilities, these new technologies do not. Make sure you have enough room between outlet and nearby moldings for these larger than standard covers.
