If possible, you should definitely go measure the magnetic fields with a quality gauss meter. Hi Janet, Thanks for your concern. Give me a few days, were teaching online this week http://bit.ly/2hOgAmf (https://healthstronghold.teachable.com). I believe they follow US guidelines here. Same advise as in the article you have to measure, then you know. [], Hi, Abroad, e.g. Hmm Been looking at a possible home but only 30 meters away from big 300Kilovolt high voltage line. Regardless, 38mG seems enormous. Thanks for your help. The plastic covering on these poles has blue stripes every few inches. High voltage power lines or tiny street power lines, electromagnetic fields should be taken seriously when considering committing to a property. Privacy Policy. This video was captured in 2002 at a BPA substation located at the Haskill tap of the Libby-Conkelley No.1 230 kV transmission line near Kalispell Montana. 8.7mG is very, very high in our experience. Good luck. Is there a source for your products in Chile? We just spent a lot of money to build a new house on this land 3 years ago, before any of this was in the works, and now we are concerned not only for our health but the resale value of our home. Can I sue city or electricity company for my financial losses? The high readings on the street run throughout the entire crescent shaped road. I recently examined no fewer than TWELVE possible housing options for my college age daughter, using my amateur tools to measure emfs and to look for possible mold issues. If you see anything or anyone that violates safe clearance measures, you should report it immediately. There are times when a line that leans in one direction is carrying 69 kV, not 115 kV. https://en.geovital.com/video-transmission-lines-being-build/ I tried to explain that in the article. For this reason, the exposure during sleep time should be seen as the most important. I live 600m from a large cinema, and just over 3 years ago they renovated the cinema and made it bigger. Buy a decent gauss meter, I suggest a TF2. Magnetic fields can come out quite a distance. 3 0 obj
This may still not produce a healthy bedroom, as there is still an elephant in the (bed)room, but it will help the body as much as is possible. Patrick, Hello Patrick I hope you can respond fast enough we are trying to put a offer for a ome we REALlY like for our Family but we are not sure if the readings we have makes sense. These lines operate at a voltage level of about 1,000 volts and can cause serious injury if anyone comes into contact with them. READ: 7 Ways Of Preventing Electric Shock. Would it be possible to answer through emails at this address. I think it is a problem with the underground power line and perhaps it has lost insulation or is spliced. 1mG (100nT) is where research starts about health affects, ranging from immunity suppression, feritity issues and cancer risk increase between 1 and 2 mG (100 to 200nT). Hi John, you have to measure then you know. Hi Paul, Good luck. We used to do a few free home assessment each month for people with cancer. As stevenal said: "Cost of doing business." Or; "If you can't stand the pain, stay off the roof." -----Ohm's law In order of magnitude (going smaller) it goes from 1 Tesla, to millitesla (1/1000th), microtesla (uT) (1/1,000,000th) to nanotesla(nT) (1/1,000,000,000th). I am trying to see if I can get any information from you basic on this article. Transmission lines do not have any color code in their plastic covering. Find out IF youre exposed to the levels we would say is concerning and if so you decide if its in your interest to stay there. So, whether for this home or any other, you should have that assessed by a professional. Once you find a home where the values are under the 0.8mG or 0.3mG depending on the instrument method of measuring, it seems to be giving you the green light. I am having a hard time analyzing the results from our EMF survey (done by a professional). When it comes to identifying dangerous power lines and ensuring a safe clearance, three types of power lines come into play: transmission, distribution and communication. Exposure to the large power transmission lines (345 kV) directly under the tower is only 96 mG, diminishing to less than 20 mG . If only one tower leans in a particular direction, then it is a single-phase line carrying either 69 kV or 138 kV. EMF radiation from phone towers, but even more importantly power lines, should be measured before buying any home. 450m-500m for 330kV Lines. please, Hi Richelle, stream
How come it is so low given the short distance? You need to make a decision if the Government is right saying 1000mG is ok or if our industry is more right wanting to see ideally 0.3mG in your living and sleeping spaces based on much peer-reviewed research. Or can I make a complaint to anyone? If you are 5% of the distance from ground to the line you will have more of a charge than if you are 3% of the distance. What would my safe distance be? Good luck. Hello, Shielding wont help you wiht magnetic fields. Do you think it could be harmful? In most countries the maximum safe exposure to electromagnetic fields is 1000mG. [] (Origineel artikel van Geovital.) Ive been having all kinds of problems, but the worst is the insomnia that started coincidentally right about when I moved in. Hi Bob, short answer is no, sorry. I did in the beginning and before you knew it your business was being covered in government body scrutiny. Im concerned with possible health effects like childhood leukemia. I am particularly concerned at the variation from one day to the next at a similar time. Fields can also increase with increased power usage. You find meters that that I do courses for including much knowledge on EMFs and what to assess and look for. High voltage power lines (transmission lines, aka the 'walkers') - anywhere within 1200m / of a mile. 230 kv transmission nominal voltage H-frame 60 to 90 feet typical height 100 to 160 feet typical right of way width 345 kv transmission nominal voltage Double circuit pole 115 to 150 feet typical height 140 to 160 feet typical right of way width The super highway: +/-400 kV and 500 kV It is difficult to simply attach a value to what a safe distance might be. For some time Then Id sell the house. When it comes to powerlines, safety cannot be compromised. You need a good quality guass meter, like a TF2 meter and probably do our online course to know how to use it and interpret it better than you would without it. You may be shocked to find out how many homes are affected by this and that many of those homes are nowhere near those big high voltage power lines. In addition to identifying whether a line is overhead or underground, you need to know which voltage level it carries. We live in the middle east and our daughters school has 2 x cell phone transmission towers behind the school yard (within 100 meters or less.) If there are no markings on poles and lines, use an electrical meter to determine what your power lines voltage level is. I would love a consultation if there was anything that can be done to correct this? For equipment with non-extensible booms: The uppermost part of the equipment, with the boom at true vertical, would be more than 20 feet below the plane of the power line or more than the Table A of this section minimum clearance distance below the plane of the power line. Hope this helps. power lines are 30-40 metres away. Most of this is covered in this very article. Determine if any part of the equipment, load line or load (including rigging and lifting accessories), if operated up to the equipment's maximum working radius in the work zone, could get closer than 20 feet to a power line. Hi Patrick. Regardless if you build here or elsewhere it is wise to do things right from the start and not create the same problems we keep finding in other homes. Hi Danni, It sounds a but like more might be going on there. Erect and maintain an elevated warning line, barricade, or line of signs, in view of the operator, equipped with flags or similar high-visibility markings, at 20 feet from the power line (if using Option (2) of this section) or at the minimum approach distance under Table A (.

Would welcome your advice on how to handle this unfortunate situation. Communication lines, also known as telecommunication or telcom lines, are responsible for transmitting telephone and cable signals to homes and businesses. -Bob. You should know that low-voltage is 0600V (low-voltage), while high-voltage is 600V and above (high-voltage). Magnetic fields vary due to electricity use variations. But the meter read s electric fields also and read high. Thank you! Within months my presence was requested at the Australia consumers affairs office as they claimed we could be taking advantage of people with cancer because we also sold products (solutions) for these people. in North America, 230 kV is often specified as the nominal voltage. Radio frequency can be deflected (phone) but radiation from transmission lines has a frequency that is too low. a 150 mG for 69-230 kV lines b 200 mG for 230-500 kV lines c 250 mG for >500 kV lines Patrick is director of Geovital International (Outside Europe), is a Geovital instructor, author and international speaker on patient focused radiation protection. High Voltage power transmission lines vary from around 100kV to over 1.5MV. Odds of ALL decreased 0.61 for every 600 meters from the nearest power line. We will probably never find land like this again. Pam. Ill send you a quick email or get one of my consultants to reach out to you.

For underground powerlines, you should maintain a distance of at least 10 feet from them. Magnetic elds(mG)Average weighted reading: 1.76 mG( Readings ranged from 1.72 to 1.84 mG ) As a result, Table A-4 Minimum Approach Distances shall apply. The majority of homes are not affected by these electromagnetic fields by a serious degree, but a home being exposed is certainly not rare either. Hi Archme, sorry for the delay. Hi the cables run up the wall at the head of the bed from the consumer unit below. Do you think it is safe, and what would you advise? Hence, if one were to look at safe values - you need to be atleast 50 metres away from domestic transmission and 100 metres for 230-400KV transmission lines. Conduct a planning meeting with the operator and the other workers who will be in the area of the equipment or load to review the location of the power line(s), and the steps that will be implemented to prevent encroachment/electrocution. Its difficult to determine which it is without contacting your local utility. If you are able to read markings on poles and lines, they will usually be in increments of kilovolts (kV) followed by amps (A). In the meantime also measure at different times of day. Im assuming where you bought it there is also nobody to ask The problem is amps. An insane high (happy to sell in that case) price sounds like the first strategy. If it is a pipe, it runs the whole length of the road. We did also measure throughout the rest of the apartment and it was >1 throughout. If you are concerned about arcing from the lines, you would be safe standing on the ground directly under transmission lines. Sorry to hear about your situation. Lower voltages are far less efficient for moving electricity across hundreds or thousands of miles to where it is needed without losing a significant amount of energy. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Greetings from Spain. There are power lines next to it and im worried that it might be too close for the pollution to be deteroation. Good luck. I found out in the beginning when I started doing home assessments, that a person can either make noise and try fight the issues of exposure, OR you can work to help people protect themselves from them. millgauss is milligauss. 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. My question is, can I use your products to help make the house safe? STATE TRANSMISSION LINE STANDARDS AND GUIDELINES Maximum Line Load State Edge R.O.W. For example, if two towers are spaced on average about 50 feet apart and one tower leans to one side or appears lower than its companion, then 115 kV power travels through that line. For the sake of reducing transmission losses, this type of transmission line is often operated at higher voltages up to 240 kV. Thank you for putting this information out there. Do u think that would drop to below 0.8 when we go 8 feet down? That said, the average bedroom needs improvements and a home assessment by one our our consultants will bring all to light. Without knowing what meter you took on-site, Id immediately think that meter is faulty or simply not sensitive enough to pick up what we need to know.

For illustration purposes in our country the following are the distances or span lengths" 1. If you are planning on building a home or other structure within 200 feet of high voltage power lines, it is best to hire an expert to do so safely. 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. Hi Mike, It could be that a bedroom close to the source, is affected by unsupportive levels of EMR whilst the distance to another bedroom is just enough to reduce the levels of EMR to a level where you get a better restorative sleep in terms of electromagnetic fields. Third, if you have access to a drone or helicopter it would be best to use one of these methods as they will provide an aerial view of what is above ground level from above. They also installed something (I assume big transformers) on the roof, which make a terribly loud humming sound that you can hear when standing outside the cinema building with busy traffic around. The calculator provides the minimum approach distance, in feet or meters (depending on your selection), for phase-to-ground and phase-to-phase exposures. Employees working as dedicated spotters must be trained to enable them to effectively perform their task, including training on the applicable requirements of this section. Think about this: Governments and local building requirements have allowed buildings to be constructed close to power lines for so many years, and condoned the placement of high voltage power lines, as well as street power lines, very near existing homes. I keep telling everybody I meet about http://www.geovital.com, but some believe me more that others. Just as there are practical limits to centralization of power production, there are practical limits to increasing line voltage. Keeping in mind that in Spain our schedules are different (lunch at 2pm / dinner at 10pm / schools let out at 5pm). On other streets nearby, he got readings between 0.6 1.0 mG. It is electricity that produces the radiation, so its the cables that it comes off. Just keep in mind that electric fields from wiring is often a problem but most amateur meters cant assess it properly. Regardless, you should get your home assessed because electric fields and radio frequency radiation are common problems. In some cases, 115-kV lines are used. Adequate and safe system operations is the result of . It is my area of expertise to assist people globally in helping them to build radiation-free homes (low in radiation. . Second, you can use a laser level to ensure that there is enough distance between you and the wires. Good luck OHS Meaning What is Occupational Health And Safety (OHS)?
