emf lcd monitors in stock
In this post, I’m going to tell you how computer monitors emit EMF radiation, how much they emit, how you can test this, and what you can do about it.
(Just a quick note before we move on. I would love for you to take just a minute and check out Nicolas Pineault’s groundbreaking E-book “A Non-Tinfoil Guide To EMFs.” It is the most entertaining and informative book on EMF radiation you’ll ever read, I promise.)
There are primarily three types of radiation sources that a computer monitor is likely to have, UV light radiation, x-ray radiation, and EMF radiation. Which radiation, and how much they emit, will depend largely on the monitor. Let’s talk a little bit about each kind.
There are basically two categories of monitors: cathode-ray tubes, and the flat-screen monitors that you see today, which are typically either LED or LCD based screens.
Prior to about 2001, almost all monitors were using cathode-ray tube (CRT) technology to power the screens. However, these types of monitors generate, and leak, small amounts of highly dangerous X-Ray Radiation. Although this had been recognized since the 60’s as being dangerous, it was not until the late 1990’s that manufacturers really fell under scrutiny for continuing to make a knowingly dangerous product.
This led to the manufacturing of Light Emitting Diode (LED) and liquid crystal display (LCD), which is what I used for nearly all modern monitors (and televisions)
Exposure to x-radiation is obviously extremely harmful and is an unfortunate bi-product of older style cathode ray tube (CRT) type monitors. The electronics in these old monitors generated extremely high voltages that would often result in x-ray radiation.
Although x-radiation that you could receive from one of these older style CRT monitors is dangerous and harmful, it is much less than you would receive from a medical x-ray machine or the x-ray at the dentist. This is the reason that they have you wear led vests to protect your body from the radiation.
Later versions of CRT monitors were slightly safer, as manufacturers began to take steps to reduce this x-ray radiation by adding lead to the cathode ray tube, which helped to cut down on this issue.
The EMF meter that the gentleman is using in this video is the older version of the Trifield meter, the company now has the new TriField TF2 (read my review), but we’ll talk about that a bit more down below in the section about measuring computer monitor radiation.
Ultraviolet light (UV) is much less harmful than x-ray radiation, but high amounts over a long period of time can still certainly cause harm. Some monitors actually have a fluorescent lamp that is part of the illumination. When the ultraviolet light strikes a white phosphor, the visible light that you see is created, but it has the side effect of sometimes leaking ultraviolet light out.
Luckily they make screen protectors for computer monitors that not only block 100% of the UV light but also help to filter out blue lights that can cause computer vision syndrome (CVS) from longterm exposure to computer monitors.
The EMF Radiation from your computer monitor will be relatively small and come from circuitry in the back of the unit. As you can see from the video above when he is testing an LCD monitor, there is still a noticeable amount of EMF radiation, but you have to be quite close.
The Long Island Power Authority did a study where they measured the average EMF radiation from many home appliances. Although they did not specifically test LCD or led computer monitors, they did test led and LCD televisions. Here are the numbers they came up with at the following distances:
As you can see, there is quite a large amount of EMF radiation at VERY close distances, but if you sit at least three feet away from the screen, you will not much need to worry about EMF radiation exposure. Be sure that you don’t sit so far away that you strain your eyes, but do keep at least 3 feet between you and the screen.
This applies to almost anything that you want to test, but you first need to start by getting a high-quality EMF meter. I personally use, and love, the new TriField TF2 (read my review). It is super easy to use, incredibly accurate, and measures every kind of EMF radiation, which you’ll realize is really important. If you need to start with a lower cost version I also like the Meterk (read my review).
Getting a good EMF meter is one of the absolute best things you can do if you care about the dangers of EMF radiation. Whether it’s figuring out how much radiation your Smart Meter is emitting, or testing to see if your microwave is leaking radiation, or comparing cell phone radiation, having a good EMF meter is the first step in knowing what the problem is, and knowing if your solutions are working.
First of all, computer monitors do emit a relatively small amount of EMF radiation at reasonable distances. So the absolute best thing you can do is keep at least a reasonable distance (3 feet or more) between you and the monitor whenever possible.
They don’t seem to make a good shield for computer monitors that are actually intended to block EMF radiation, but they do make this window film that you can pick up on Amazon, that you could cut to fit the size of your monitor if you really wanted to reduce the amount of radiation you’re exposing yourself to.
EMF meters are used to identify the presence of electromagnetic fields, called EMFs, within a given environment. While some EMF frequencies have always existed naturally, in the last 30 years levels of man-made EMF radiation have grown exponentially, with many concerned about the potential health impacts caused by this.
EMF detectors can range in function, allowing users to detect various EMF frequencies, either to gain an understanding of the levels of EMF around them or as part of a shielding project.
Ionizing EMF radiation can come from radioactive sources, alongside X-rays and UV light. This radiation is recognised as dangerous worldwide, causing cellular damage and serious medical issues over time. In the UK, our exposure to ionizing radiation is strictly limited by law.
Non-ionising radiation however is all around us and is not subject to the same legal limitations. Sources of Non-ionising EMF include power lines, cell phone towers, and electrical items in the home. While these forms of EMF do not pose the same immediate health risks as ionizing radiation, concern has been growing for decades about their effects on the human body. They have been linked with a huge range of symptoms including insomnia, headaches, fatigue and more serious illnesses.
EMF detectors vary in accuracy, capability, and quality. There are three specific types of EMF meters, high frequency, low frequency, and dirty electricity. High frequency (HF) meters measure radio frequency from applications like mobile phones and Wifi routers. Low frequency (LF) monitors will measure either electric or magnetic fields from areas like house wiring, domestic electrical appliances, and pylons. Lastly, dirty electricity meters are specifically designed to measure electrical disturbances on wiring circuits. Each EMF meter we sell has been thoroughly tested by our EMF health experts for quality, upholding our commitment to demonstrable and long-lasting products. We also offer a specialist 5G EMF meter, the FM5, which can monitor the highest frequency 5G millimetre wave signals.
Digital EMF meters will measure up to three different types of EMF radiation. Radio frequencies, known as RF signals, will come from Wifi routers, cell towers, smartphones and more everyday devices and can be measured with dedicated RF meters. Magnetic fields, known as MF signals, will come from sources like fridges. Finally, electric fields, or EF signals, will come from the same sources as magnetic field radiation.
Each EMF monitor offered through our site meets our high standards for efficacy, allowing us to ensure that all our customers can receive a quality piece of equipment, regardless of their budget.
When looking for an EMF meter, the best choice for you will depend on your needs. If you are looking to take detailed EMF measurements regularly, then you could benefit from one of our professional EMF meters such as theFM5, whereas those simply looking to check the levels of EMF within their house could be perfectly served by one of our entry-level options, such as theCemprotec 35. Another popular choice is theTrifield TF2 EMF Meterwhich can detect RF, magnetic, and EF signals.
If you are looking to monitor dirty electricity specifically then you should opt for one of our dirty electricity monitors, with ourLine EMI Meterused to measure a general environment and ourNoise Analysersuited for more localized testing. Our newFM5 Path Monitoris the only handheld meter capable of measuring very high frequency 5G signals, available now at a competitive price.
EMF Protection was founded in 2004 by Glynn Hughes, who became concerned about the effects of EMF radiation after his daughter started experiencing EMF-related sickness after moving to a school built under a cell tower. In that time, EMF Protection has grown into a trusted industry name, offering a huge range of dependable and functional products.

Even the World Health Organization admits that EMF radiation at certain levels can trigger symptoms like headaches, stress, suicide by depression, vomiting, fatigue, and loss of libido.
Yes, but it’s mostly the old CRT monitors that are concerning. Newer LCD screens don’t emit as much. The more immediate threat stems from the blue light they emit.
It depends on your distance from the monitor. Inches away would give you 25-500 mG of EMF radiation, 1 foot emits 0.4-20 mG, while 3 feet emits just 0.1-1.5 mG of radiation.
Monitors emit such a low level of radiation that most agree it’s not a concern. However, even low levels over long periods of time have induced side effects like headaches and depression.

Additionally, if you are on your computer, cell phone, tablet, television, and other common devices, you are also dealing with EMFs. Electromagnetic frequencies - or EMFs - are low-level forms of electrical charges that move through the air. These are created by almost everything that has a plug. The more time you spend with your devices - especially if they use WiFi to connect to the Internet - the more EMFs you are exposed to. Why does this matter? Some people may experience sleep disruptions, brain fog, or even notice that they feel more distractible when they are around EMFs often. In fact, this is one of the reasons that some people recommend that you sleep with your phone at least two feet away from your head: to keep it farther away, lowering the EMFs that can reach you while you sleep (and since you’re not actually working for the 8ish hours you’re in bed, this is a great opportunity to unplug).
If you’ve ever wondered if there was a way to reduce the EMFs in your environment using crystals, the answer is yes! Here are four of the most-common EMF-reducing stones that you can use - and, bonus, they are pretty easy to find (you may even already have a few) - so you can start addressing your EMF exposure right away.
Shungite is a stone found exclusively in Russia. It is a black, carbon-based material that has been said for years to be extremely good for absorbing EMF rays and for "clearing up" anything that is negative. It is said to be protective, shielding, and clearing. Shungite comes in several grades (or qualities) and can be rough or polished. Elite Shungite is the highest quality (and price point), containing approximately 98% carbon.
These crystals are all known for their EMF-protecting abilities...as well as their other energetic properties. Additionally, several of these crystals - particularly black tourmaline and hematite - are amazing crystals for grounding and connecting to the Earth.

Through the NIOSH Worker Notification Program, NIOSH notifies workers and other stakeholders about the findings of past research studies related to a wide variety of exposures. The links below present archival materials sent to participants in studies related to EMF from video display terminals.
Disclaimer: If you are experiencing symptoms – headaches, sleep issues, rashes, etc.. from EMF exposure (microwave sickness) you will need to take additional measures than are on this page.www.electricalpollution.comis a great online resource. We also highly recommend contacting a professional, such as a BuildingBiologist, who can inspect your home or other location, take measurements, and create a professional remediation plan. This resource is not medical advice.
When it comes to screens and electronics, there are different types of non-ionizing EMF exposures doctors are cautioning us about. The two we will tackle today arewireless radiationwhich is radiofrequency electromagnetic fields (RF-EMF) from the Wi-Fi, Bluetooth or Cellular antennas, andextremely low frequency electric and magnetic fieldsfrom the electrical system (referred to as ELF-EMF in this post for simplicity).
In the newly publishedstudy, Kaiser Permanente researchers found pregnant women’s magnetic field EMF exposure associated with ADHD. The research team has previously published replicated findings ofincreased miscarriageand in addition, increasedobesityandasthmain prenatally exposed children. Thus, low EMF computing is critical for pregnant women who are now teleworking.
As families set up computer workstations at home, we hope they can integrate these practical steps to reduce exposure to wireless radiation and other electromagnetic fields. We also hope this information inspires everyone to get involved in critical efforts to create meaningful long-lasting policy changes. 5G should be halted. Governments should pass laws to reduce EMF exposures and schools and workplaces should have safe technology networks and infrastructure.
Computers, laptops, and tablets should always be used on a hard surface, rather than against the body. All wireless screens emit two types of EMFs, radiofrequency wireless radiation and electric and magnetic lower-frequency EMFs. As the distance from the source increases the intensity of these fields will decrease rapidly, therefore electronics should never be on the lap. Always use devices on a table. Another reason for using a table is because bending over to stare at a screen can result in text neck and other damage to the spine and posture.
Corded phones (with the curly cord) are easily found in stores or online. We recommend choosing a low-EMF phone as some corded phone handsets emit strong magnetic fields. Phones that have the dial pad on the handset tend to have higher electromagnetic fields (EMF). If you want to have caller ID you will want to purchase a phone that is “line powered” so that it uses a battery and does not need to be plugged into electricity.
People often use their laptops while plugged into the charger. However various types of EMFs are more intense emissions from a charging laptop because the device is plugged into electricity, especially if you are using a two-prong power cable (that isn’t grounded). Read how laptop manufacturers clearly state the human body conducts electricity from the laptop with a two-prong plughere.
You heard that right. Wired headphones from your computer to your ears can allow some electromagnetic radiation to travel up the wire and directly into your brain. Prefer a wired speaker, or if you need a headset use airtube headsets. The airtube stops the EMFs from traveling to your head.
Understanding the actual intensity levels of the various types of electromagnetic radiation in your home is very important. You will detect sneaky sources of EMFs and also have a great tool to raise awareness among family, friends, and in your neighborhood.
Safe Living Technologies is a company that sells Safe and Sound Meters and many materials to reduce EMFshttps://slt.co/Products/RFMeters/SafeandSoundProIIRFMeter.aspx
If you follow these steps you will be able to reduce a large amount of unnecessary electromagnetic fields from your computer area, therefore significantly reducing the dose intensity and duration of your firsthand and secondhand EMF exposures, and reducing the EMF footprint you make. These are the basics.
However, for more health-protective choices or if you may be experiencing EMF-related impairment or illness already, there are more steps you can take.
Please check outwww.electrical pollution.com whichhas more details on how you can further reduce EMFs. See alsoJeromy Johnson’s website formore resources on reducing EMF in your home.

Since computers began dominating home and work environments, health concerns have arisen about prolonged computer usage. In the late 1970s and 1980s, workplaces were more concerned with basic comfort and about the toll on people"s backs of sitting in front of a screen for hours; in the 1990s, people were concerned instead about Carpal Tunnel Syndrome from extended keyboard use. Since the turn of the millenium, health advocates have become concerned with radiation from the electromagnetic fields generated by computer monitors.
All computers create -- and therefore emit -- electromagnetic fields (EMFs), which are a source of radiation, however minor. In the early days of home computers, most used cathode-ray tube (CRT) monitors. Bulky, boxy monitors once populated offices, though as of July 2011, most have been replaced by the slimmer, sleeker -- and healthier -- liquid crystal display (LCD) monitors. In addition, all laptops use LCD screens. LCDs are not EMF-free, but studies have shown they emit lower EMFs than CRT displays.
EMF radiation is present in all but a few specially-designed monitors, and the jury is still out on how harmful the levels of radiation from LCD screens might prove to human health. According to Safe Space Protection, "computers typically measure from two milligauss (mG) to five mG"; 2 mG and higher can potentially damage biological organisms. Despite this claim, the article "Harmful Electrostress from Computers/Laptops" doesn"t specify what kind of computers create this level of radiation, though the article does state that LCD screens and laptops are "much safer" than CRT monitors connected to desktop computers.
According to Danielle Barone, the family health editor for BellaOnline.org, even LCD monitors and laptops emit "enough radiation to affect your health and appearance." While the majority of computer users don"t seem troubled by this, some may wish to exercise a bit more caution. Barone suggests buying what"s called a radiation filter, which blocks between 94 percent and 99 percent of the radiation from your computer screen.
Ultra-health-conscientious computer users -- those who want to reduce their exposure to radiation at every possible turn -- can find and purchase 100 percent radiation-free LCD monitors. The website BlockEMF.com offers hundreds of EMF-preventing products, including four LCD monitors that the company guarantees to be completely free from radiation.
The TriField EMF Meter Model TF2 is an AC gaussmeter, AC electric field meter, and radio power density meter in a single unit, that combines all the features needed for fast, accurate measurements of electromagnetic fields (EMF). In addition to standard AC measurement modes, a special frequency weighted mode will properly scale the magnetic and electric measurements to indicate the full magnitude of currents produced by each type of field inside the human body.
