". The consultant can then also investigate for the more common radiation types we find in most homes (electric fields in the bedroom and radio frequency radiation from phone towers etc. Frequency ranges: 50-60 Hz Type of field: electric and magnetic Measurements (acc. My parents have been living here for 5 years now and havent had any new health issues. Is this something to be concerned about and what device can I use to measure the EMR/EMF (or whatever it is)? 2- underground power lines cause cancer?? There are times when a line that leans in one direction is carrying 69 kV, not 115 kV. Hi Janet, Thanks for your concern. If you are able to read markings on poles and lines, they will usually be in increments of kilovolts (kV) followed by amps (A). My wife and I are looking at downsizing and having a home built in a new subdivision in the town we live in now. Good luck. There are transmission lines on the highway 330m+ away but the readings dont seem to be coming from them. Due to higher power consumption, existing power lines generate higher magnetic fields. Buy a decent gauss meter, I suggest a TF2. 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. Over 1,000 kV, the utility/owner or a registered engineer must establish it. the cables run up the wall at the head of the bed from the consumer unit below. I already had a lump in my breast. Most power lines in North America are at 115 kV, but 230 kV is also common. The radiation from other sources (wiring, phone towers etc) will need other better meters. Dont rely on a calculation. Being underground doesnt stop magnetic fields, but they might not be strong enough to increase risk of disease measure and youll know . Now they are changing the towers to run 260KV. 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. Good luck. Or should i not even think of planing a school on that site? 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. 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. Its strength depends on a number of factors, but how much and how strong the electricity is that flows through is significant. We did also measure throughout the rest of the apartment and it was >1 throughout. Hope it helps 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. READ: 7 Ways Of Preventing Electric Shock. By doing this you dont make your offer less attractive and reduce your chances it gets accepted. Safe clearance distance from power lines. *According to 1926.1409, for power lines over 350 to 1,000 kV, the minimum distance is presumed to be 50 feet. Each type of line presents a different voltage level to professionals working in proximity to them. 0.3mG (=30nT) or less is ideal for the bedroom. Meters Feet Enter system voltage (kilovolts rms, maximum): Enter maximum transient overvoltage (per unit)( 1): Altitude (in meters): Phase-to-ground exposure Next door to my apt is some sort of a control panel and I guess the cables run along my bedroom wall. I have complained to my landlords and to the City, but I have no way to prove it since no one will believe me. As a result, Table A-4 Minimum Approach Distances shall apply. Odds of ALL decreased 0.61 for every 600 meters from the nearest power line. You can purchase a quality gauss meter to investigate just these fields, or get a consultant to assess this and the other more common sources of radiation in a home. Good luck. 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. 2.0mG (vs 4.0) at 12m. 20mG? If you feel immoral selling a house to someone that may make them sick I can understand that. Buy EMF meters and monitor your exposure. Ive been having all kinds of problems, but the worst is the insomnia that started coincidentally right about when I moved in. If so, the employer must meet the requirements in Option (1), Option (2), or Option (3) of this section, as follows: Determine the line's voltage and the minimum approach distance permitted under Table A (, Determine if any part of the equipment, load line or load (including rigging and lifting accessories), while operating up to the equipment's maximum working radius in the work zone, could get closer than the minimum approach distance of the power line permitted under Table A (. please, Hi Richelle, The reading from app in my mobile giving the reading for emf is 110ug ( microgram) please let me is that ok to live in? (Boy did I love to holiday there when I was a kid) I wonder if there may be stray current on cables and pipes which can happen in older suburbs more so than newer ones. An insane high (happy to sell in that case) price sounds like the first strategy. need advice, Hi Raghu, But before moving here we measured the magnetic field and surprinsingly it was 0,01-0,02uT which is 0,1-02, milligause I suppose. If you are considering the purchase of an amateur meter, then please see the available online course I have some some meters at healthstronghold.teachable.com. I have children and dogs and I recently was diagnosed with breast cancer. power lines are 30-40 metres away. Exposure can also vary during the day, so measure morning, day, evening and night too. endobj The only concern is that the house is located 400 meters from 238 KV high voltage power lines. Do you think it could be harmful? =1v4:v| [UTI`a rXT}g)r,VP T;05,QJ Find one on our site or contact the office that looks after the area youre in. Hi Mike, I will email you and we can discuss how we can assist you with your new home. Would welcome your advice on how to handle this unfortunate situation. Sanya. If you come across a line and arent sure if its a power line, do not assume it is not! If this article was of benefit, if you have personal experience or questions, then please leave a comment below. The power lines voltage level can vary in different areas, so you have to be careful when working with them. Good luck. Hi Archme, sorry for the delay. Thanks in advance. North Carolina, Virginia. Dear Craig, interesting question. But before you panic, MEASURE first. Determine if any part of the equipment, load line, or load (including rigging and lifting accessories), could get closer than the minimum clearance distance to the power line permitted under Table A (see 1926.1408).If so, then the employer must follow the requirements in paragraph (b) of this section to ensure that no part of the equipment, load line, or load (including rigging and lifting . 3 0 obj How come it is so low given the short distance? 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. Ive just moved into a rental house that is within 200m of HV power lines. The uT (microtesla) reading will be the magnetic field value. Hi Bob, short answer is no, sorry. The 2Km distance from the transmission lines seems a nice distance but no doubt your home will have the usual problems like electric fields and RF radiation if we dont help you. Good luck. They are so loud that at night in our bedroom I can hear the humming faintly in the distance. In Australia, the minimum clearance distance from the centreline of 275kV transmission lines is 25 metres (~75ft). Hi Patrick SERVICES: What is involved in a home health assessment? Ive tried to answer your question by video. I had EMF inspection done with below readings. Having a 220KV transmission tower anywhere in a school is absolutely foolish. It would say .4 and I walk 10 feet and now its only .01. You can use your personal EMF detector to see if your home is receiving the EMF radiation. Obviously we would go back and take more readings. I'm interested in hiring someone to do an independent test before we make an offer. Less than 0.3mG is ideal for the bedrooms at night. I can do some consulting over the phone at a cost and help you investigate this yourself. 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). Your electrical powerline is delivering up to 120,000 volts of electricity to your home or business right now! Not sure. The last thing you want to do is mess with those high voltage power lines, but how much clearance should you keep between those power lines and your house or office? We used to play in the hydro fields, cut through the fields to go to school etc. Its tough. Hi Gemma, sorry to hear this information came to you too late. Ill send you a quick email or get one of my consultants to reach out to you. Hi there, In the yard of the home we love did not make the soung but not sure if the readings still safe for our family. Does anyone know where I can get a device that measures all of what was mentioned in the article? And what are the dangers of walking across the power lines themselves? The need for crew in the area to avoid approaching or touching the equipment and the load. Upstairs bedroom rear of home steady 0.2mG (thought I was measuring towards front of home but got mixed up with realtor starring at me like Im nuts!). The ongoing exposure to EMR can slowly start to ask its toll. Whats the difference? Cranes and derricks are required to take additional steps before beginning work (see OSHA Standards 29 CFR 1926.1400 effective Nov. 8, 2010). But the readings jump around so much its hard to tell. If you see a sign that says High Voltage or Warning: High Voltage it is best to call an expert before proceeding with any further investigation. Patrick. I am having a hard time analyzing the results from our EMF survey (done by a professional). As an Amazon Associate I earn from qualifying purchases. 3.7 Meter. Plus i am concerned that at some stage they might up the voltage of the lines!! I am over 80 and not to up on computers thanks for all you do! 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. Where necessary, use equipment that enables the dedicated spotter to communicate directly with the operator. The higher the voltage the higher the tower that supports the line and the greater the clearance from the ground. Examples of a visual aid include, but are not limited to: A clearly visible line painted on the ground; a clearly visible line of stanchions; a set of clearly visible line-of-sight landmarks (such as a fence post behind the dedicated spotter and a building corner ahead of the dedicated spotter). Hi! If you say transmission lines are nearby, this would even more question the accuracy of your app and I wouldnt put much faith in that measurement until it was verified by another proper meter. But I think this is the wrong attitude to have. But I stayed for years because I could not bring myself to sell it to anyone else. It should be: https://healthstronghold.teachable.com Line passes above or adjacent to any building or part of a building. Im not sure how far away they are. I wont be able to measure with the gauss meter until the lines are put in later this year. Can that happen? I have been investigating emfs with the trifield meter. Now they are building a 750KVA transmission line literally 50 feet from my bed room. HI Patrick! The modeling method is validated using two case studies with field measurements. Only a few spots left though. Patrick. Sara. So I dont think they will care much about my puny 1mT (10mG) readings. The voltage of translines ranges from 35,000 volts to 765,000 volts and can cause severe injury or death to anyone who comes into contact with them. Give me a few days, were teaching online this week http://bit.ly/2hOgAmf Two-phase lines can carry 60 kV on one phase and 115 kV on the other phase. Wouldnt READ: PAT Testing (Portable appliance testing) All You Need To Know. The safest means of evacuating from equipment that may be energized. Transmission lines, also known as translines or power lines, are responsible for bringing electricity from generating plants to substations. 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. Best to have it assessed with meaningful instrumentation, and then you have to make your own decision where you place your faith and if staying in a given situation is a good long-term strategy for you. 15 meter sounds close but you need to measure your exposure. 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. Alex. It is my area of expertise to assist people globally in helping them to build radiation-free homes (low in radiation. The same advise applies: You have to measure and leave a little space for fluctuations in exposure and for the fact that more power could be used on those lines in the future. Im guessing the effect is linked to long term exposure over an extended period of time or a lifetime. When electricity flows an electromagnetic field is created that kind of swirls around the source of the radiation like a whirl wind. A year is definitely prolonged exposure. I would love a consultation if there was anything that can be done to correct this? With him working from home he spends most of his time there. Power lines are presumed to be energized unless the utility owner/operator confirms that the power line has been and continues to be deenergized and visibly grounded at the worksite. Practically right under it Tink Ill pass even without measuring the field. So, measuring it with an app, I would not expect to have much accuracy. For a growing number of Q&A videos, visit my personal site: http://www.healthstronghold.com, Hi Patrick, Shielding is ineffective. Thats a decrease of 6.0-7.0 mG in 6 meters? This study . * Florida 200 mG a, b, c New York 200 mG * R.O.W. 230-kV Transmission Line in Delta and Montrose Counties, Colorado.
