I had a sort of eureka moment once I put the pieces of the puzzle together. Is there a way to pre-calculate distances if you know amps, wire size, etc. Good luck. The magnetic fields near gas lines, or phone cables, or water pipes can indicate a flow of current where it is not supposed to be. Do u think there is a connection ? 2.0mG (vs 4.0) at 12m. Thanks for sharing Micky. Top 10 HSE Certifications You Must Have . So I dont think they will care much about my puny 1mT (10mG) readings. Could the (safe) readings inside be accurate? Reddit and its partners use cookies and similar technologies to provide you with a better experience. I am obsessively concerned and have done a lot of reading online! I cannot however understand how giving them some money helps with that at all? I hear this every night and it disturbs my sleep. You could get a consultant to check if internal wiring may be adding to the exposure, but if the power lines are close and the field strength increase and reduces in a logical pattern in relation to the distance from the lines then youre pretty safe to say they are your problem. The high readings on the road are on the inside of the crescent along with street lighting. A great tool for that is the Trifield TF2 because magnetic fields are you highest priority and it does that very well whilst also showing RF levels. Is a house 300m from those high voltage transmission line safe enough? Measure the EMF in areas where you and your family spend a lot of your time like living rooms, kitchens, and bedrooms. The uT (microtesla) reading will be the magnetic field value. They normally have MANY power lines, finished pipe structures, or other items that come to an end here. endobj 3.7 Meter. thanks for all you do! Magnetic fields can come out quite a distance. Any research showing the opposite would be simply disregarded as being inconclusive or somehow not applicable. mind hearing your thoughts. You can use this page to calculate minimum approach distances for phase-to-phase system voltages exceeding 72.5 kilovolts in accordance with 29 CFR 1910.269 and 29 CFR Part 1926, Subpart V, as follows: The calculator provides the minimum approach distance, in feet or meters (depending on your selection), for phase-to-ground and phase-to-phase exposures. For example, over 50 to 200 means up to and including 200kV. The calculator provides the minimum approach distance, in feet or meters (depending on your selection), for phase-to-ground and phase-to-phase exposures. Best to measure exposure and move desk to an area where exposure is acceptable. . Magnetic fields must be avoided as they cant be shielded against. But I stayed for years because I could not bring myself to sell it to anyone else. I can say this when it comes to other apartments being under the same roof and exposure: Be careful announcing your findings People have threatened to take legal action because one home owner started raising the alarm which may affect the property values. From my time as a real estate agent, in my opinion, you are better off not putting an offer subject to a home health/EMR pre-purchase inspection, but rather do it before you put the offer in. We used to play in the hydro fields, cut through the fields to go to school etc. I am having a hard time analyzing the results from our EMF survey (done by a professional). We will probably never find land like this again. TIA, Hi Eugenia, Patrick. When uncertain of a power line's voltage, stay 20 feet away for voltages up to 350 kV and 50 feet away for voltages greater than 350kV. We live in a different state, so we cant do another test. You can also listen to my podcast on this subject: https://www.healthstronghold.com/living-near-power-lines-004/. The large power transfers along the West Coast are generally at 230 or 500 kV. We bought house and there are transmission power lines going from right beside this house. Pam, Hi Pam, My parents have been living here for 5 years now and havent had any new health issues. It is a concern also I noticed and observed my body beginning to tremour at another house, in the front bedroom, where I know the readings are above 2 milligauss due to the power draw of the owner in her bedroom with an electric blanket, a tv and receiver, a cordless phone, a router for the internet, an emergency alarm. Battery charging devices for tablets, cell phones, etc. Hope this helps. Plus i am concerned that at some stage they might up the voltage of the lines!! This electromagnetic radiation (EMR) cannot practically be shielded against. Any thoughts on if maybe it reads the mG in a different scale and its actually safe? I live 600m from a large cinema, and just over 3 years ago they renovated the cinema and made it bigger. What do you recommend I do? However, on his way out, he was surprised to find readings between 10.0 11.0 mG across the street (where street lighting is) ~18m from the front door. The problem with magnetic fields is that you cant really shield against them with something that is effective, affordable and has a chance of success. It is a tough one Perhaps offering a bargain price (compared to properties not near high voltage power lines) is a way to have peace with ones conscience I dont envy you for being in this situation, if this applies to you. Can you suggest what to do in that property? I wonder if there may be stray current on cables and pipes which can happen in older suburbs more so than newer ones. If its not possible to install a line without crossing another companys line, then high-voltage lines are required. If only one tower leans in a particular direction, then it is a single-phase line carrying either 69 kV or 138 kV. It is for sale frequently, gets sold and some time after is back on the market for a long time. Regardless, you should get your home assessed because electric fields and radio frequency radiation are common problems. Next door to my apt is some sort of a control panel and I guess the cables run along my bedroom wall. 15 meter sounds close but you need to measure your exposure. Determined by the utility/owner. You offered below to do a zoom consultation. It is electricity that produces the radiation, so its the cables that it comes off. With my Trifield 2 Ive measured 6.36mW/m2 in the kindergarten play area. Hi Shari, The terrain has a major influencing role. We are looking at another home with underground power cables. I am over 80 and not to up on computers In a distant past Patrick van der Burght gained experience in real estate. We live 80 meters (260 feet) from huge power lines. If you are able to read markings on poles and lines, they will usually be in increments of kilovolts (kV) followed by amps (A). Will we be safe? This is because current at these levels ca not even penetrate your skin or cause any damage. And it states stay 800 feet away. Good luck. When we went to look at the model home and saw the map of the homes that will be built in the next phase, we saw some property that looked like we would be interested in securing now when that phase eventually gets into development. Thank you! Health affects are well documented from levels of 100nT and in our industry we say ideally we should see maximum 30nT in a bedroom environment. Measure the same locations at different times of the day. I have for you, answered your question in a video which Ive just uploaded. There has been very high mG of 85 and 90 on the ground under my gas service entrance. Frequency is calculated in cycles per second. I have taken your amateur class and it saved my family (with 3yon) from a potentially unhealthy home. How come it is so low given the short distance? Well answer these questions in this article on how to identify powerline voltage level and safe clearance. Looking into purchasing a home near some transmission lines. You cant shield against magnetic fields and they have been linked to cancer in multiple studies. Your electrical powerline is delivering up to 120,000 volts of electricity to your home or business right now! With him working from home he spends most of his time there. I appreciate your honest and informed advice. The strength of low frequency electromagnetic fields is expressed in milligauss (mG) or nanoTesla (nT) or other values. So you should be concerned if your house is situated either: Less than 25 meters away from street pole power lines Or 200 meters away from major power lines Where this measure is selected, the dedicated spotter must: Be equipped with a visual aid to assist in identifying the minimum clearance distance. mG (milligauss) is an expression of magnetic field strength. For underground power lines, assume it carries a medium voltage level unless otherwise marked. 1- 33000 power lines cause cancer or Brian toumer? As a result, Table A-4 Minimum Approach Distances shall apply. Exposure to the large power transmission lines (345 kV) directly under the tower is only 96 mG, diminishing to less than 20 mG . Very interesting to read. If moving bedroom or house is just not an option then you should reduce all other sources (the common ones) of radiation, in specifically the bedroom, to attempt to make the burden as little as possible. 220KV generates high intensity emf and that can affect nearby electronic and electrical equipments. Hi Patrick Many SCE 230 kV transmission upgrades and new 230 kV power lines use 1590 aluminum conductor steel-reinforced (ACSR) cables, one of largest listed in the ACSR datasheets . If there are power lines above the house (around 50 meter above the house) but one tower is located at least 200 meters away, do power lines themselves emit EMF or only the towers? Provided the meter is accurate, that would be one of the worst homes Ive come across. We dont have consultants in Spain yet. I have had the electricity company out to take readings. 10-15 meters sound very very close. But, given what you describe, it sounds like magnetic fields may be high and you cant shield against them so measure first and then assess if its a good long-term strategy to stay there under those circumstances. The radiation from other sources (wiring, phone towers etc) will need other better meters. If you are working with underground power lines, always wear rubber-soled shoes when digging near them so that if there is contact with electricity running through them, it will travel through your body instead of through soil or water which could result in damage to property or injury to others nearby. Please consider buy my online course for the TF2 (or for the ED88T) with it so you are confident on how to use it. Everyone has to come to that decision themselves. Approximately 12m from the front door measured 4.0mG. When we left the new subdivision we noticed that the phase we were looking at building in had the high tension lines running near it. 45 ft*. Hi Simon, What is the closest you would feel comfortable living, Hi Craig, The online course can be found at healthstronghold.teachable.com Hope it helps and you take the warning at the end, to heart. At healthstronghold.teachable.com you can purchase a 3 hour online course on EMF home assessment and using that meter specifically to give you the confidence youre using it right. Hello, I live with high voltage power lines next to my back fence and I am just learning about all the health effects due to health symptoms I am experiencing myself. Patrick.
