‘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.
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.
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.
