I have been saying for some time now that this house has some sort of pulse waves and was thinking of purchasing a reader of electromagnetic fields or what not is there specific types more suitable? Yesterday I was talking with a neighbor for the first time and found out he is an electrical engineer working in the solar industry. Just this summer we bought a Trifield TF2 EMF meter and have made adjustments and rid the house of more EMFs that we were not previously aware of. WiFi uses radio waves to provide network connectivity. Or is it because the AT&T box where he installed? I apologize if I missed this part, but I couldnt find it. Also, is there a main hub where everything connects in a neighborhood that can be identified (and avoided!)? She is even injured by the tower and it seems to be what has given me the stroke and heart attack. Its not so much of where the cables are located (they are generally out at the street, either on poles or underground). Yes, EMI and DE are similar. Excessive signal loss due to a contaminated connector. But a flip phone wouldnt allow me to download anything. All of a sudden, I cant watch tv without being affected and couldnt sleep all night. Most neighborhoods wont have those until fiber optics are installed in the community. I use an older Radio Shack AM radio (model 12-467 or older on Ebay) to see if there is wide spectrum EMI on the wiring. just louder even when I used it for CD to play music. WebOne theory is that fiber might prevent this disease by affecting hormone levels, like with breast cancer. The concern around WiFi and routers causing cancer is due to the emission of these EMFs. Your router connects to the fiber optical modem (ONT). I hope I will be around to see it in my lifetime, but a lot is going to happen and is happening. Carlberg M, et al. See the videos I have of this in the comments above. WiFi and the electronic devices that connect to it, such as cellphones, laptops, and wireless headphones, are all around us. We inquired at the Observatory about EMF in the area. Yes I can see your point, but things are changing and lucky for all of us God is in charge and making changes and these will ultimately be part of the change. This is now how you use the AM radio. If you check the category of locations and tools on that Facebook community you will find multiple tools to locate the towers and safe locations. Thalamocortical alpha frequency oscillations have been noted in the human occipital-parietal cortex. https://www.emfanalysis.com/fiber-optics-increasing-electrical-sensitivity/. Hello Jeromy, is there a meter that can tell me how much dirty electricity my cable modem is pumping into my power lines? More research is needed to determine if radiation from Wi-Fi can lead to cancer. In most areas, even the most basic package is much faster than you will need to stream movies on Netflix or Amazon. 2.) Also, the music sounds better because theres no more uhm, buzz etc. Are there solutions you can think of that manufactures can provide? I have requested they move the box which they told me no. https://www.emfanalysis.com/work-with-me/. (2017). Electromagnetic fields and cancer. World Health Organization, radiofrequency radiation and health a hard nut to crack (Review). Bought ten USB active signal converter for the ten PS2 mice. The radiation creates areas called electromagnetic fields (EMFs). Tk L, et al. Ionizing radiation is described by the National Institute of Environmental Health Sciences as mid- to high-frequency radiation that can, under some circumstances, lead to DNA or cell damage after extended exposure. An AM radio is also well advised. That is more for EMI coming in off the electrical grid. How to See Clearly While Wearing Glasses with a Facial Covering, 5G directly spreads SARS CoV-2, the virus that causes COVID-19, 5G impairs your immune system, increasing your risk of contracting SARS CoV-2, COVID-19 first appeared in Wuhan, China, because it was the first city to use 5G. (2011). Do you or do you have technicians that can go to homes and do all of the things you recommend? My next article will cover what I do in a home that is served by fiber optic internet (see #7 above). Thank you. Then there is no harm at all. Heres a new topic I must explore! Thanks! It will reduce the electric fields and EMI coming to your computer (steps 2-4 are what you need to do): When working with Spectrum/Charter, you can buy your own non-WiFi Arris modem model TM1602A: That will keep things from turning back on. Given our frequent contact with wave-emitting devices in the home, you may wonder whether EMFs. The scientists pointed to data showing electromagnetic fields generated by cell phones, wi-fi and baby monitors may impact human health. Pall ML, et al. If you want to have a consultant come over to look at things, let me know your area. I encourage you to move to a different building asap so that the sensitivity to this does not increase. It will give you a paper book for now to get you going. As I mention above in the response to Marks comment, having a low-emission media converter, along with GPON fiber all the way to the home would be a great solution for everyone. To a certain extent, this is unavoidable or needs to be filtered before coming into the home (see point #5 above). Have you looked into the quantum photon hologram shield technology? In case Karl Riley is not monitoring this page, let me point you to some resources which might answer your question. I am not familiar with the low-EMI/EMF modem models/providers in Australia. And, if you are moving to VoIP through a fiber modem (ONT device), that will surely add more EMI to your in-home landline phone. Hopefully this will help more people understand that EMI does come in from the telecommunications infrastructure so that they can eliminate it. Akdag MZ, et al. This is why for now I recommend that ES people continue with cable internet. I have to keep checking it because they randomly turn it back on. Required fields are marked *. a step-up in my previously low-level tinnitus to an all-time high and at a very high pitch a pitch that I have not encountered before. Many newer fiber optic networks operate with zero power in between the signal origin point in the Telco office to the actual fiber modem / router / WiFi combo in the customers house. There is a big 3-story apartment complex being built up the street from me and it has a brand new cell tower that stands within a hundred yards of the structures. www.ecmweb.com is using a security service for protection against online attacks. I am also currently suffering from illness from EMF exposure and was advised by my physician to lower it as much as possible. These can typically be found on Ebay or elsewhere online for $20-$30. It will either be phone line DSL, cable or fiber optic. Every cellular antenna on a light or utility pole needs a fiber connection to operate. In other words, is it like solar panels, that spread EMI everywhere on the neighborhood grid and everyones electrical wires, except in this case its getting spread on copper wires and internet cables? Do you trust lists like this for SAR ratings? Otherwise, the fiber networks can be used to radiate the entire community with RF. You can hook as many devices as you want up to a home fiber connection. to create fiber optic technologies which support accessibility needs for electrosensitive people around the world? From the O.N.T. Hi Jeromy, thank you for everything you do, and thank you for personally answering my email the other day, amazing!!!! * Im assuming we are talking dirty electricity?. When/if you update the electronic version with any essential info, will you let buyers know? As of yet I have not given consent, but time is ticking. Bluetooth uses the generally harmless non-ionizing type of electromagnetic waves. We have a very sensitive son and we just found out that the fiber optic junction box will be in our front yard. Consider this EMI issue when choosing your service. So, this is an area of which I need to be EXTREMELY careful! I have read that we should be concerned about 5G. Our Online Second Opinion program lets adult patients from all over the world receive expert second opinions from Dana-Farber oncologists without leaving home. Perhaps the people who have contacted me with symptoms from fiber / high speed data systems had the older system you mention above in their communities. (2014). Consider filtering the EMI before it comes into your home. I know so little about this subject and Im frantically trying to read all I can in a short amount of time. Thank you so much for the article. 3. Use it to trace the source, whether in the street or from your own wiring or devices. I typically just run long Ethernet or fiber cables in my home. Im often kicked out with my current DSL line which is affecting my business. I have received hundreds of emails from people in several countries who report an increase in, or initial onset of, electrical sensitivity symptoms when high-speed fiber optic internet is installed in their neighborhood. I guess Ill have to wait to see the article to understand better! I noticed that when I am using the internet through a LAN in our apartment complex, my hands can feel the electricity and it radiates to my back. Vila J, et al. Thanks. Its complex and vitally important, but I think we will eventually figure it out. https://www.quadro.net/internet/shop-by-speed/internet-packages/fibre-faq/. https://www.statista.com/chart/12841/the-phones-emitting-the-least-radiation/. Question What about the fiber optic junction boxes? So far, there is no consistent evidence that WiFi routers or WiFi-powered devices increase cancer risk. We employ a strict editorial process to ensure that what you read is factually correct. The place is a mess. Wear disposable aprons to minimize fiber particles on your clothing. I have to stay at an AirBnB that has 4 very strong wifi networks according to my cell phone (all full bars). But first we have to bring to awareness that this is a problem. I started researching anything and everything that could be causing this and I realize they had just installed fiber optics at my complex unfortunately the box for my entire building where they put all the connectors in is right outside my bedroom window. Finally, this is what I do for a landline setup even when going through the modem: https://www.emfanalysis.com/analog-phone-system/, Jeromy, you write: it is low-frequency, electronic devices are all around us, and always on. Every computer will be very loud within a couple feet of the device. Residential is in a small confined space and has more soft bodies present (humans and animals, in other words). Now do I know, I am an EE so I do know a little bit about this stuff. I explain the topic correctly in a way that any beginner can understand: https://www.emfanalysis.com/healthy-home/, https://www.emfanalysis.com/how-to-create-a-healthy-home/. Glad the low-EMF steps are working well for you. The sensor was used to measure the backscattered and transmitted light from frozen and unfrozen ex vivo porcine tissue and in vivo human skin tissue (finger). Will be easier to go over all your question that way. But the researchers didnt state the possible mechanisms behind these results. Thanks for the reference to your article on the analog phone and amplifier. As for cell towers, antenna search is good. Insects and birds are dying and my dog is sick. Ill show how I also do this with a fiber connection in my next article (to be published soon). See Marks comment for more on this: https://www.emfanalysis.com/fiber-optics-increasing-electrical-sensitivity/#comment-8780. I will discuss this aspect of small cellular antenna installations in a future article. In 2011, the World Health Organizations International Agency for Research on Cancer (IARC) stated that EMFs are possibly carcinogenic to humans. The label was established by 30 scientists who evaluated studies on EMFs and cancer. Bough it because one EHS person tolerated it. That is a big if though at this time and most likely the stock media converter they give you is going to be produce a lot of EMI, which will then go on all the copper telephone wiring in your home (if that is all it is hooked up to). Many communities have multiple internet service companies to choose from. Glad the article has been timely for you. 2) How do I find out where all the cell towers are in our area? Please enable cookies on your browser and try again. Thank you so much for keeping us all aware of such important environmental pollutants! So I went to the shed and turned off power supply to the ONT. Learn More, Stay Connected Most modems will create a lot of EMI, both from their operation and dirty power sources. For a summary of how fiber optics can be installed properly, please read my statement here. But he did not know about the RF issues so I told him my story and gave him your website. However there are providers in the area that utilize the existing telephone line that I can choose from (at least for now and the foreseeable future). Seems like moving is definitely a wise move. Local laws need to be put in place that dont allow this. However, it doesnt capture most of the newer small 4G DAS/5G antennas. We are in a rural area of FL and have only been in our home for 2 years, but with the addition of these new towers it really worries me. You will eventually want to measure the EMFs. Fiber may be the only venue in the future, but Ill definitely be waiting until that point to consent to the technology if counteractive technology is available at that time to eliminate any EMF/EMI. Thank you so much for your professional advice back then and now also! I also know that it is best to use at bare minimum a CAT6 Shielded cable to reduce EMF emissions. Obviously, you want an ONT device with no WiFi as well. Still trying to understand it. * Remove all Smart Meters and put the Analog Meters back. My wife can hear the sound and walks the floor in pain from the tower. If not what rating of CAT cable would be best for the job in terms of limiting EMF radiation? Im pretty sure its directly associated with the installation. Passive splitters are rapidly replacing old hybrid fiber / coax systems that would have been placed on poles or in pedestals. The ACS says on its website that it does not have any official position or statement on whether or not radiofrequency radiation from cell phones, cell phones towers, or other sources is a cause of cancer. Most U.S. government health agencies, including the CDC, FDA and National Cancer Institute, have stated theres no evidence to support a connection between wireless devices and cancer. The differential mode meters (Stetzer / Line EMI) wont pick this up. A nearby cell tower invades our house with frequency radiation. I always wondered about this. As you look for a new home, just be aware of the type of telecommunications used. I am going to find out exactly what they are going to install and will get back to you. WebThe fiber also can be used directly as a transducer to measure a number of environmental effects, such as strain, pressure, electrical resistance, and pH. Both use forms of radio waves to send signals, but they differ in other ways. Im about to pick a new net provider for the next year or so and am choosing between Xfinity coax which I already have, it has a clear impact on the houses DE, or trying AT&T fiber which is true fiber. The cheaper 3-in-1 meters are not accurate at all and can be misleading. have differing flicker rates. The power adaptor of modem measures 700-800V/m 380mG at the power connection and all power points in my home measure 700-800V/m, including the Ethernet cable to laptop and all phones connected to VOIP. This answers the 5-month issue I have had with electrical sensitivity. I think there must be 8-10 boxes attached. It only measures RF (cell tower, WiFi, etc). I bought four 32 x 32 aluminum sheets from Home Depot and I placed them on the floor right above the spot where the modem is in the room below. 2005-2023 Healthline Media a Red Ventures Company. Not soI will print this and bring it to our next meeting! The router can then connect to dozens of devices if you want (all wired hopefully). This is all getting so complicated and it seems the options are limited. Thanks, Jeromy. You seem to have a better understanding of this than me. What part of the country do you live? This is the best way to bring fiber to the home. So would this solution also work for 5G? In the review, Hardell says this is a conflict of interest. If that doesnt work, then my next article about putting a home fiber optic system between your computer and the modem should do the trick (#7 above). The problem is, I live in a remote area and not a lot of options. But theres no solid evidence that Wi-Fi causes health risks in humans. Keykhosravi A, et al. I think you would still agree that fiber is much more energy efficient than wireless. In fact, youre likely reading this article on a device thats currently connected to Wi-Fi. Thanks for the reply. But the fiber is in the lawn now and if the ONT is going to stay in the shed, will it make EMF in the house? Hence reading your article, on reading comments and came across the YouTube videos on picking up electrical interference! WebHow can fibre reduce bowel cancer risk? I offered to loan him my RF detector so he can check his house. Optical fiber glass is just silica glass. It is not known to cause cancer. You typically cant get cut but you can get a puncture and a splinter! O The fact that it hit me at that point and not before makes me wonder if it was the computer itself that was the problem the massively increased speed might have enabled the computer to work at a new level of efficiency and with it, send out a whole lot more radiation. Wonderful that you have connected the dots! + one computer is a Macbook pro 2015 with *SSD*, seems to give zero symptom 5G is the newest wireless network. We live in a wireless world. 5G, or fifth generation, is another type of wireless technology. Oxidative stress is known to contribute to the development of cancer. A report by the consulting firm Deloitte estimates that the average American household has as many as 25 wirelessly connected devices. So, as you can see, fiber optic cables play a vital role in global communication. There are no truly low-EMF phones (and SAR is a very misleading calculation meant to give people a false sense of security). I just submitted my consent for fiber optics in my neighbourhood, hoping there would be no problems with it being wired. Thought they had as there were large box that always hear a fan at end of our street, thought was fiber. I have wondered myself whether the conversion back to electricity (and the conversion to light) could potentially be a problem with respect to EMI emissions and electrosensitivity. This is all leading up to a question: If you can keep your same DSL connection for now, stick with it until you learn more about this and have a prudent path forward where you know the solutions will work for both of you (for instance GPON fiber to the home with a truly low-EMI media converter, once we find one that has been made). Non-ionizing radiation is generally considered harmless to humans. Thank you and God bless you! The problem many times is just getting enough fiber to the area, which would have been under estimated in years past when designing the HFC systems. Does prolonged radiofrequency radiation emitted from Wi-Fi devices induce DNA damage in various tissues of rats? Is there a possibility for a cure after this (electromagnetic sensitivity) happens to you? When I ran the article by a very knowledgeable EE he explained how both the phone line DSL and cable lines are not effective radiators when they are installed properly. I like to do my computer work in an area that has the circuits turned off. * Remove all 5G antennas Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. My only option to switch is Spectrum. Send me a message for more information on EMI filtering options. Of course I know theres radiation of the phone antenna is on, but there are ways to download files and listen offline. This month Comcast installed underground fiber optic cable and they turned it on yesterday. The two primary sources of EMI from high-speed internet service are the fiber optic converters at the street and the cable modem within your home. Could you clarify something for me? EMI, EMFs, RFIs, VHFs Is there a way to get pdf /printable versions of your blog entries like the one above as well as the Comments section with your incredibly helpful responses to the comments? I think your EE acknowledges my point when he uses phrases such as are not *effective* radiators and that EMI is the *primary* issue. But does it affect health? Sometimes the fiber lines are above ground, up on the poles. Electrosensitive people will have limited access to essential services if wired options like fibre optics dont fully support their long term health. Web1. Seek the Light we have to change. Smart home devices can turn off lights from across the room, and security cameras can send images from across town. You do want to check the fiber optic cable coming into your home for EMI. This O.N.T. Yes, I do have some good recommendations. Id like to know if theres any difference in EMF exposure. Yes, if you remind me about your purchase, I will send you the updated version. requires a 110v electrical outlet for power supply and also contains a battery backup of up to 6 hours. It is easier to order them online at http://www.sportys.com/pilotshop/ Click on Charts and Maps, On the dropdown meno, click on Sectional Charts, Then hover over the map and pick the area you want. I can send you his very technical explanation if you email me. If you ever want to discuss, we can have a Skype/Zoom call. It would be so great to see videos of how you deal with EMFs at home, travel, etc. I have a master's degree in engineering and had a successful career in Silicon Valley before I began to experience negative health effects from wireless technology and electrical pollution. + the last computer is mobile, new and not checked, dispensing digital anesthesia Or should I move to a completely new complex As soon as possible? The have kept their phone line DSL or cable internet connections until they know more about the new system. This is how I do phone/Skype consults: Yes, electromagnetic interference (EMI) is the proper engineering term for dirty electricity. DE is just the term that has been popularized. So, I would be wary of what they are offering. I cannot say Thank You to you enough, Jeromy!! Both are a part of a healthy diet that can help lower your cancer risk.
