‘I live near power lines. Can I shield against the magnetic fields?’

We are approached frequently by people who live close to ‘power lines’, have measured magnetic fields with a gauss meter and ask us how they can reduce their exposure or if shielding paint or GPA mesh would reduce their exposure. When people speak of ‘power lines’ what they are talking about is what is called ‘transmission lines’ (big walkers bridging large distances of the countryside) or ‘local distribution lines’ (the electricity supply network going through the streets of a neighbourhood) that may have a high voltage but are still low frequency (50 to 60 Hz typically).

The bad news is that magnetic fields from these ‘power lines’ can realistically not effectively or economically be shielded against. There are a few other things you could do, so please read on.

Shielding paint T98 or GPA shielding mesh

Depending on the frequency of the magnetic field, the wavelengths of the magnetic field have a certain distance. The area within 3 wave lengths is called the near field. The area beyond 3 wave lengths in called the far field. Shielding is not effective inside the near field. For 50hz or 60hz a wave length is thousands of kilometres (or miles) long and shielding by ‘deflection’ doesn’t work. Hence our shielding paint T98, our shielding mesh GPA or our shielding fabric NOVA are powerless against it, and so are all other similar shielding products no matter what they may say.

Mu-Metal as shielding against EMR is too costly for families

Mu-Metal as shielding against EMR is too costly for families


There is a man-made material called MU-metal which affects magnetic fields. It changes the way the magnetic field travels but doesn’t make it disappear. You would have to completely incase a room or house for this to work at some level and it is very very expensive which makes it economically unviable. If you did one wall against, lets say a meter box/circuit breaker panel, then directly behind it you would see a reduction but if you measure in other spots you may find an increase which makes it very unpredictable to use. You would be better of having the wiring more tightly fitted (ask us) or check for wiring errors which are likely the cause of magnetic fields around meter boxes anyway.  For protection against ‘power lines’ MU-metal is, in my opinion, unsuitable for the average home owner.

What can you do against magnetic fields from power lines?

Shielding is certainly not a option. Avoidance is the best approach, meaning you purchase a quality gauss meter before you commit to a house and measure before you sign the dotted line. I wrote another article about this last year. On a flat measuring instrument you would ideally see less that 0.2 mG or I would say at least less than 0.3mG. Above this… walk away. On a weighted measuring instrument, like a Trifield meter which is very popular amateur meter, you would be unlikely to see 0.2 or 0.3mG and you would more look for less than 0.8mG. This is where that gets tricky as with a weighted measuring instrument you are never sure if you are really looking at particular value or if it has been inflated due to the fact it is a weighted measurement and multiple field or different frequencies are affecting its indications. For this reason, always have a Geobiologist double check your findings with their professional instrumentation in a pre-purchase inspection before you commit to a property.

Normal street power lines are much closer to homes and can cause the same problems are high voltage power lines.

Normal street power lines are much closer to homes and can cause the same problems are high voltage power lines.

It could be that uneven flow of current (between the hot and neural) in the ‘power lines’ is causing a significant increase in magnetic field exposure. This can be caused by the return current from an electricity user (factory or home) not following the normal path due to a fault like a wiring error (neutral to ground) or broken neutral. In that case, you could try going through the neighbourhood with a gauss meter and trying to find a property that has very high magnetic fields near it. This could indicate there is a problem with their return current which can affect the whole neighbourhood including the exposure at the front of your home from the local distribution lines running past your property. If you need help with this, our Geobiologist can assist you but it can take a lot of time and may be fruitless. If a fault was found, you will need to try to convince those property owners that they have a problem and you have to convince the electricity company to do something about it. This can be challenging as the levels we and you are worried about can still be far below the exposure limits deemed acceptable by government.

If you can’t move away from power lines, what could you do about living with magnetic fields?

Ok, you have a problem, but if selling the house and moving is just not an option, what can you do? Well, you should deal with every other form of electronic pollution in the home (of which there will be many) and geopathic stress, to try to make that home the healthiest it can be. This included the electric fields from the internal wiring affecting you whilst you sleep, shielding against RF radiation from transmitters like phone towers and smart meters and excesses of natural radiation from the ground. Shielding with T98 shielding paint and GPA mesh which are both grounded in the process will reduce the exposure to the electric fields from the power lines. If the magnetic field from outside power lines is there to stay, then at least remove every other burden so it is the only one. Will this bring you the health recovery you are hoping for? This is unknown. The hope is that your body has enough restorative power left to ‘deal’ with the magnetic fields and improve your health beyond that. Could all the effort and investment be for nothing? Yes, in a way it can be, in relation to certain symptoms you were hoping to fix, but regardless you have improved the environment in that home by reducing the overall exposure.

In addition (but no substitute) you can also support yourself by a healthy diet and maybe supplementation with certain key nutrients which has been explained in an article on this website by one of our Geobiologists who is also a nutritional therapist.

Planting some fast growing tall trees between you and the power lines will also help reduce the electric field exposure from the power lines onto your property or yard, as the trees will absorb and lead away the electric fields. They won’t do anything against the magnetic fields though.

I guess this might not have been the answer you were hoping for but at least you know why shielding against magnetic fields from power lines is pretty much impossible and you can strategies with that knowledge going forward. Contact one of our Geobiologist for their consultation services to help you.

Good luck,

    I live on a “Main” power transmission line. It feeds several towns north. I live at the beginning and have heard arcing and sizzling all the time. It runs down my backyard very close to my home…30 ft. I bought a trifield meter out of curiosity….I measure 800+ near my house. My home has old aluminum siding, which I try to keep well grounded. Does FCC have any regulations on this?

    • Patrick van der Burght 17/04/2024 at 2:32 pm - Reply

      If you were using the meter correctly and that was indeed 800mG than that is very very very high. I have never seen that before.
      Most governments has rules and they state that 1000mG is harmless. So…… you’re fine…. WHO says 3mG should be the maximum and our industry says 0.3mG.

    I am about 70m away from a transmitter and have done a test that says 70.61uT. What the hell do I do ?! I have 3 children under 5 🙁

    Can you please elaborate on how much trees help block electric fields?

    Currently I cannot be closer than 20 meters from a distribution line without symptoms. The magnetic field is low enough, but the electric is over 200 V/m (measured with a Gigahertz Solutions meter) at about 7 meters. Ideally, I would love to see ~15 V/m at 7 meters. Is that realistic? Can trees possibly block that well?

    What difference might there be to have shorter trees/bushes closer to or directly under the lines, versus taller trees further away?

    Thank you for the work you do!

      Hi Alicia,
      If the trees are close enough I would imagine that is possible to achieve (you won’t know till you try but what have you got to loose?)
      Watch this video. This is during our EMF3 workshop when consultants and consultants in training come to get more practical experience.
      In the video we walk to one tree near transmission lines. Now imagine what a row of fast growing trees would do against the electric fields of a small local distribution line 🙂

    Thank you for the article, wow I am late getting here. Just moved in an apartment checked for RF which was good but unfortunately I wasnt well versed on Magnetic fields. Since the power line is right outside my second story apt.. im getting 1 to 3 readings in the apartment on the trifled meter for magnetic fields. The furtherest room goes down to one. I am going to be living in that room! LOL..

    I live about 120 meters from huge power lines. Do you think this is far enough to avoid most of the dangers, or am I too close, in general of course? Thank you

      Hi Gabby, thanks for the comment.
      120m is pretty close.. it depends how big these things are and how much power goes through them.
      You really need to measure.
      I’ve just launched some small courses online for amateurs on how to use amateur meters like the TF2, UHS2, TM-190, Cornet ED88Tplus and more coming. Go here to see the ‘multiple-meters course’ or the cheaper single meter course for the meters that this is available for at the moment.

      Good luck 🙂

        Does room cover it with aluminum foil prevents radiation from these power lines? Or is it ineffective?

        • Patrick van der Burght 31/12/2019 at 2:30 pm - Reply

          It’s in the article. Magentic fields go through pretty much everything so aluminium foil won’t do anything against it.
          Good luck and happy new year!

            I’m being asked to sign an easement agreement for the underground installation of a 525kv cross country power line. My residence is 50’ from the proposed line.

            Do I need to be concerned about electro magnetic fields?

  7. Carolyn Luce 23/04/2018 at 5:25 am - Reply

    Hello. I just came across your article which is very relevant to me. about 6 weeks ago the magnetic fields in and around my house became quite high, increasing by a factor of 10 overnight. I have 3 to 4 mgauss in my kitchen and as I am Emf sensitive this has caused all kinds of symptoms to return. I have contacted the utility but ass of yet they don’t care and just keep saying that as far as they are concerned there are no problems with the grid. I measure fairly high levels throughout the neighbourhood, especially along the underground line that runs past my house. My question is how canI identify the source of the problem? From your article it seems like wherever the highest value is found would be the source of the problem. Is that correct? I live in France by the way and did call some geobilogists in but they were not able to identify the source of the problem. As it happened on an unusually cold night, my theory is that water got into the lines and froze and something broke, a neutral perhaps? Does that make sense? Thanks, Carolyn

    Well, given that EMF from power lines is about 12 orders of magnitude less powerful than light, you don’t have much of a case. Get the real facts and stop wasting time setting the field up for sales of useless “protective devices”.

    I got emf measurement done in my house and the numbers are above the average…due to proximity to power lines. Moving away at this stage may not be an option. In that case i wanted to know if there is a way I can reduce the magnetic fields In my house.
    Is there someone who can survey the area and advise.

    My house near on overheading cable power line…but i have a big acacias trees…the distance from the pointing area from top to the ground is 14meters…is my acacia can help us to protect the radiaton from the power lines? Coz they want to cut it ? Can u give me an advice? Pls regards vicky

    • Patrick van der Burght 20/06/2017 at 10:46 am - Reply

      Dear Vicky,
      Thank you for reaching out to us. Power cables produce two radiation types; Magnetic fields and Electric fields. Magnetic field are penetrate almost all materials and so your exposure to them won’t change with the trees being there not not.
      However, electric fields are like little invisible lighting strikes or arcing, which like to connect to ground. The tree contains water and so is a surface it will want to link to. The tree would then lead the electric field to ground and reduce your exposure to them.
      If the trees are between you and the power cables in the air, then the having the trees there would definitely be a good thing and you should try to keep them there. This is of course, given you have exposure to begin with. If you need help investigating, we may have someone near you or we could teach you how to help yourself.
      Good luck.

          Hi Vicky,
          I’m not sure what legal rights you have to avoid electricity distribution systems from being placed near you. The argument of ‘health being affected’ is often a difficult point to fight as you are basically saying that all other power is too close to homes too. You might be better of to get neighbours and councils on your side fighting from a point that property values will drop if they are installed.
          Not a nice situation to be in, that is for sure.
          Good luck.

            Hello sir …., im here again to ask some couple questions again…im sorry to disturb u again…. i just wanna ask if how many meters or distance from the floating cable wire and also from the tower plant …. should be safe?

          • Patrick van der Burght 31/08/2017 at 4:40 pm

            Hi Vicky, thanks for the question.
            It is hardly possible to put a figure (a distance) to that question. There are many variables, and so, if an answer was too conservative, you would be worried for nothing or someone would avoid a home purchase for no good reason. If the answer was not conservatively enough, one might think you are fine when you are not. The only thing you have to go by, is a measurement. Therefor you must buy a quality instrument (spend at least U$300) and go measure. I know health effects have been recorded up to 1200 meter distances from transmission lines, so everyone considering committing to the home, should measure before committing. Regardless if its a transmission line or underground power cable. Our consultants can also assist with a pre-purchase inspection.

          • Vicky 01/09/2017 at 3:40 pm

            Hello sir….thanks for that…i really sorry for lots questions….we measured already…its only 107 meters from transmission to the houses which one the house is mine…is this not safe right?
