Cheap way to shield EMF (Electro Magnetic Field) in house?

Question

I have service lines for over 6+ condo units, that run under my bedroom floor in a condo i recently purchased. I bought a Gauss meter which reads up to 10 MG in Milligauss, as well as .1 to 1 mG for EMFs.

My readings are high for both, reading the max/red zone around the point in the floor where the service wires are underneath. (they run in a single bay between floor joists). The EMF's would be right under our bed, And we will be putting the mattresses on the floor.

Being were putting down new pergo floors, we wanted to put some kind of EMF shielding under the floors to deflect the fields away from our bed.

Everything I have found online is around $400-$700 for what we need.

Does anyone have any suggestions of materials that we can buy (sheets, foils etc) as an inexpensive alternative to the expensive EMF shields found online? I know nickel and steel might be good, where would i buy thin sheets of it?

Thanks for any help!

I was considering Aluminum, but read the following:

Here's how the permeabilities of some common materials compare:
Air ........... 1
Copper ...... 1
Aluminum ... 1
Tin ............. 1
Lead .......... 1

Nickel .................. 100
Commercial Iron ... 200
Stainless Steel ....... 200
MagnetShield ........ 4000

Magnetic Shielding Alloys* ....... 20,000+
Annealed MetGlas ................. 1,000,000

Answer 1

You have two issues. EMF for most people relates to radio waves and the emissions from overhead power lines. Where the radio effect is far greater than the magnetic effect.

Because of your proximity to the lines you describe, you get magnetic influence as well, hence your Gauss readings.

Aluminum or any conductive metal, connected together and properly grounded will do a great job shielding you from the radio portion of these emissions. But to stop magnetic fields, you must redirect them. This requires metal with iron, such as sheet metal. A 4'x8' sheet of steel, 0.060" thick will run you about $65 - see example link below. Lay these over the offending area and then attach a ground screw to tie them into a decent electrical ground.

You should see a significant improvement in EMF and Gauss reduction with your meter.

Unfortunate for you, those power lines running directly under your floor.

I know that foil does an excellent job on ordinary cables for TV's . It is only a single wrap and a steel ground shield around that and does a very good job on this product..

You can buy foil sheet by the roll, it has two sides of aluminum foil and a center of polyproplene. The material comes in 10 foot wide and costs about 18 cents a sq foot. It is used as a reflective insulation in building construction. A source on line is RadiantGuard, 11244 Old WorksDr. RiscoTX 75035 They have a website.

On steel galvanized sheets, those come in variety of sizes and can be purchased at steel supply houses and Heating and Cooling supply houses. The cost is about 40 cents a square foot for this.

Have you tried to determine what the acceptable levels are for occupied space.
In addition to the magnetic fields generated around a conductor might want to see what radio frequency levels are also.
If you are concerned ( I would be) look for a shielding contractor to have a survey done to measure Gauss fields as well as RF levels.
They will be able to tell you if you are at any risk according to current standards & make recommenddations to remedy situation.
An official report by a certified engineer can be used as leverage to have the condo management. correct the situation .
You should not have to bear the expense of shielding yourself from a potentially harmful situation .
Used to work for a medical imaging co.
Operators of MRI, Xray & other devices are responsible to contain & protect surrounding occupied spaces from any emissions from their equipment.
Hope that helps.

With the floor up, try putting down heavy duty alumimum foil and stapling it across the joists. You will need to ground the foil to a water pipe or other earth ground. Once this is done take another reading and see how much the reading has decreased. Good luck with it.

Nope

Answer 8

paint . there is now a shielding paint manufactured by'ECOS'
in the UK .can be pricey but is worth it

Answer 9

that is crazy that they run under your floor, that sounds illegal, but, this may be wierd, you may want to go to nearest university and talk to physics doctors, they know all
