lcd screen radiation free sample

A simple flat screen emits very low levels of EMF radiation. But the new generations of smart TVs emit stronger EMF signals. They will often emit both radio frequencies (RF) and Bluetooth radiation.

These old TVs actually emit low levels of X-ray radiation, which is much more dangerous than the other types of your EMFs we are concerned with from newer screens.

LCD TVs were the first types of flat screens to enter the market after we went away from the old bulky TVs we mentioned above. They are still found in many homes and they are filled around the fluorescent technology.

LCD TVs are powered by CCFL lamps. The screen is lit up by these lamps. CCFL is short for “Cold Cathode Fluorescent Lamp” and that means that we are dealing with fluorescent light.

You need to keep some distance to these monitors. You should stay at least 4-5 feet away from the screen in order to get the levels below the safe limits.

It’s not the best option if you are using this screen as a computer monitor. Because you will typically be sitting very close to the screen and you will (probably) often be leaning forward even though you try to keep 4-5 feet distance.

It’s simply not possible to switch off the Bluetooth and the RF signal to a smart TV. It will always be emitting RF radiation because it will constantly search for or communicate with Wi-Fi routers in your room.

This is always the option we recommend. The computer monitor is the best choice when you want a radiation-free TV in your living room or your bedroom.

We need to talk about ELF radiation and RF radiation separately. If you don’t know the difference you can start by reading the article we have written here about ELF and RF radiation.

Basically, ELF radiation is coming from the electronics inside the TV such as the transformer that generates power for the TV. The RF radiation, on the other hand, is coming from the countless wireless signals we have around modern smart TVs.

Plasma TVs do use much more energy than the two previous TV-technologies: CRT and LCD screens. So you need to pay attention to the electromagnetic fields close to the screen.

But as with all electronics, as soon as you add a few feet of distance to the screen you will quickly minimize the level of ELF radiation (we have an article here with more info about what ELF radiation is).

This is because the radiation levels are following what we call the inverse-square law. It states, that every time you double your distance to the source of the radiation (the TV in this case) you will lower the amount of radiation four times.

So we don’t have to be too concerned about the EMF levels coming from the electronics inside the TV and the screen itself. As long as we remember to not sit directly in front of the screen. We always need to add at least 4-5 feet distance to the screen (which shouldn’t be a problem as we have giant screens today).

RF radiation is radio frequency radiation which we typically find around routers, cellular signals, and Bluetooth technologies. If you want to know all the basics about this type of radiation we have written a good solid article here about RF radiation.

All smart TVs will constantly send out a signal in order to connect to a Wi-Fi router. It doesn’t matter whether it actually connects to the router or it is just looking for it. The radiation will be constant and you cannot turn this off (on any smart TVs we have seen, at least).

It would also send out a Bluetooth signal in order to connect to other wireless devices. This signal is also RF radiation even though it is typically a weaker signal than The Wi-Fi signal.

It’s important to keep your distance to smart TVs for this reason because it will emit radiation close to the same levels as a small router. That’s why we strongly advise you to get rid of the smart TV and use a dumb computer monitor instead.

It’s always better to get rid of any electronic device inside our homes that constantly emit RF radiation. The smart TV is definitely high up on this list.

Even though you keep your distance to the TV, you might still be exposed to the RF and Bluetooth radiation. If you have a device close to you which is connecting with the TV it will create a two-way communication line with the TV (and probably your router as well).

Plasma TVs are quickly being phased out of the market. All the biggest manufacturers have moved on from this technology several years ago. When you buy a flat screen today it’s most likely LED or OLED.

Personally, I’m a big fan of taking the matter into my own hands. I want the newest tech but I also want to keep myself and my family safe from EF and other types of radiation in my home. It’s simply stupid that you cannot turn off the Wi-Fi signal even when you’re inserting an ethernet cable.

The only other option you are left with is to get an EMF meter and make sure you do some readings on the TV before you buy it. You might be able to find a TV where you can switch off the RF radiation. But you shouldn’t take anybody’s word for it. Even though it says on the screen that you are switching off the wireless signal you might still find that it emits full speed.

The sales person at your local Best Buy store might not know anything about RF and Bluetooth radiation either. So don’t even bother asking. They will just give you a long speech on how this is not dangerous because they read an article over at Bloomberg or NYtimes.

The problems arise when we are dealing with smart TVs and other types of computer screens that connect wirelessly to other devices such as our router.

You might not be able to find a 50 or 60-inch computer monitor at the local store but you can find computer monitors up to 65” at best buy. Asus and Samsung also have some great widescreen and curved computer monitors that can just as easily be used as TVs.

This is definitely the easiest solution for you if you don’t want to open the TV and dismantle the Wi-Fi device as we showed in the video above. It can be dangerous to open TV screens and computer monitors and it’s definitely not something we advise you do unless you know what you do or can get help from an electrical engineer.

Be aware that the resolution on computer screens are often much higher than on TV screens. They were also many times be cheaper because people are willing to pay more for TVs than they will for computer monitors.

It’s impossible for us to list all the different types of TVs and how much EMF radiation they emit. There’s simply too many brands and models for us to cover them all.

I really like this EMF meter because it has a very user-friendly interface and is easy to use. On top of that, it’s pretty accurate and you can measure RF radiation (wifi, smartphones, laptops, Bluetooth, etc.) as well as magnetic and electric fields.

Some new generations of smart TVs will still emit RF radiation from the wifi and Bluetooth signals on standby mode. We also have electric fields as soon as the power cord is attached to the socket. When we disconnect the power cord we eliminate all radiation.

When the TV is turned off you will often have the wifi signal and the Bluetooth signal turned on as well. As long as the TV is set to standby mode. The only way to stop these signals is typically to pull out the power cord. As soon as you do that you won’t have any radiation from the Wi-Fi and the Bluetooth signals.

So, in order to eliminate the radiation altogether, you typically need to remove the power cord to the TV. As soon as you do that you will have removed all radiation.

The radiation from an infrared remote control is much less than the radiation from a remote control using radio frequencies. So you should always go for an infrared remote control whenever you have the option.

The same goes for the latest versions of Samsung’s TV sets. You cannot turn off the signal which is the big problem if you want to get rid of EMF radiation in your home. You might still be able to find earlier versions of Samsung TVs (used) where you can actually turn off the Wi-Fi signal as you plug in the ethernet cable instead.

You should also be aware that the gaming console itself (the main box) typically emit very strong RF radiation in all directions. The worst among the gaming consoles when it comes to EMF radiation is the Xbox. It sends out loads of EMFs even though it’s turned to sleep mode or standby. If you like your gaming consoles you should read our article here on EMF around the Xbox.

The last thing we have to look at and this article is in relation to the blue light from the screen. We get blue light from computer screens as well as TV screens, smartphones, tablets, and other devices with screens.

Many people even have a TV screen installed above their bed so they can fall asleep with the TV on. Even though that sounds like a very pleasant thing you need to pay attention to the blue light waves that come from the screen. You can overcome this problem in several ways:

Several TV screens will give you the option to change the lighting on the screen. You will probably find a setting where you can tone down the blue light in order to create a better viewing experience before bedtime.

They are developed by Daniel Debaun who also wrote the excellent book “Radiation Nation”. It’s a great book for anyone wants to get into EMFs and educate themselves a little bit more. You can get the book at Daniels store here.

Measured values for both TV and PC screens can be found under "screen". As far as possible, they are distinguished acc. to the technology employed (e.g. cathode ray tubes, LCD screens). Flat screens are based on LCD or plasma technology; the employment of cathode ray tubes is not feasible due to space requirements.

For a tube screen, the central element is a cathode ray tube. During its thermic heating, electrons are emitted and deflected by a magnetic field of a certain frequency. In horizontal direction, the deflection frequency is 15.625 kHz, in vertical direction 50 Hz. Having hit the fluorescent screen, the electrons generate a light spot. Its brightness dependent on its position on the screen provides information about the image content. In order to depict a complete picture, all pixels are passed line-by-line.

In contrast to that, the main components of an LCD (Liquid Chrystals Display) screen are liquid crystals. Each pixel corresponds with a crystal. Its transparency can be controlled by a given voltage without influencing the adjacent crystals: Once a voltage has been employed, the crystals change their permeability for polarized light. The polarized light originates from a background illumination, followed by a polarization filter.

First of all, to answer the question, do TV’s Emit Radiation, the answer would be yes, but only a small amount. That is because modern TVs that use LCD, LED, or Plasma screens only emit a small amount of radiation from the circuitry, and not really from the screen. Previous versions of the TV that used Cathode-Ray Tube to power the screens emitted an enormous amount of radiation.

With that being said, TV’s still do emit enough radiation at a close distance that it is worth keeping your children and yourself at a fair distance. However, if you’re watching the television from the couch or anywhere more than a few feet away, EMF radiation is not really something you will need to worry about.

I also just want to quickly mention that if you’re worried about EMF radiation from things like 5G, cellphones, routers, or anything else, there is an E-book that I absolutely cannot recommend any higher called “The Non-Tinfoil Guide to EMFs” that I would really encourage you to check out. I didn’t write it, but it’s one of the absolute best resources available.

Just about any electronic device that has a circuit board is going to emit some EMF radiation. How much radiation the device emits, or the kind of radiation completely depends on the build of the device. I’ve written articles on radiation emitted bymicrowaves, refrigerators, washing machines, and even alarm clocks, just so you have a little better understanding of how even simple home appliances can emit harmful radiation.

Although this is a relatively small amount of radiation if you have a small television, it is certainly measurable. Skip down to the section about how to measure EMF radiation from your TV for more on this.

This “dirty” electricity gets stuck in the lines and emits EMF radiation. The only way to simply get rid of it is with a dirty electricity filtration system.

Many, or most, TVs either come with smart tv features built in, or are using a connected box to provide access to things like Netflix, Hulu, and more. Since these are wireless devices that require a large amount of data to be transferred back and forth, they produce a large amount of EMF radiation via radio frequency.

Like we talked about above, most modern TVs can emit a very large amount of EMF radiation, but not for a far distance like the old CRT versions could. Obviously, every TV is going to be dramatically different based off its size, the brand, the quality, the technology, whether it has built int smart TV functionality, etc.

However, the Long Island Power Authority did a study of EMF radiation emissions from home appliances, and concluded that the average TV produced the following amount of EMF radiation at these distances:

These televisions when it comes to EMF radiation are relatively safe and are a popular option. However, measures should still be taken to reduce your exposure to these types of TVs, which I’ll cover down below in my section on reducing radiation from TVs

This will not be much different than the EMF radiation from an LED TV, as the circuitry required to produce the light necessary for this type of TV is not really any different than the LED TV.

Plasma TVs emit a small amount of UV radiation, as well as other types of EMF radiation from the circuitry. Plasma TVs, like any modern TV, only emit a small amount of radiation at reasonable distances, but at a very close range can expose you to a fairly large amount of EMF radiation.

Although they do not emit any x-ray radiation like older CRT tv’s did, plasma TV’s often come in very large sizes, so be sure you have a fairly good distance between the watcher and the TV.

The danger was so great for early TVs however, that the Food and Drug Administration (FDA) mandated a program called the Electronic Product Radiation Control panel that was tasked with evaluating the x-radiation from electronic devices.

In 1969 the panel decided that the federal standard would be set that TV receivers could not emit more than .5 milliroentgen per hour (mR/hr) of x-radiation. These amounts would be determined based off the maximum radiation emitted, ensuring that under normal use conditions this would be far less, and safe for the household.

There are ways to connect your Smart TV to the internet via ethernet, which for any device is always a better option as it will dramatically reduce the EMF radiation from WiFi in your household.

Smart TVs are also often a bit more demanding with power usage because they essentially have a small computer inside running an operating system that allows you to browse through various applications. To compare this with a modern TV that does not have built-in smart TV functionality, think of attaching an iPad to the back, and you’ll be able to have at least some picture of the increased amount of EMF radiation.

As radiation passes through an object, it is reduced, this is called attenuation. As an example, the lead vest you wear at the dentist attenuates the x-rays, and the tinted windows on your car attenuate the sunlight. Well, your skull and brain matter attenuate radiation. Since a child’s brain and head are smaller, it is capable of penetrating deeper.

Next, children also have much thinner skulls. Bone actually does a reasonable job at attenuating EMF radiation, but it cannot stop it, therefore a thinner skull will allow more radiation to penetrate.

As you can see in the video below, your TV is going to emit EMF radiation, of several kinds. The best way to know just how much radiation is being emitted is to get a good EMF meter. I always recommend the new TriField TF2 (read my review) as it’s simple to use, lasts forever, is extremely accurate, and measures all three types of EMF radiation. If you’re looking for a low-cost EMF meter I really like the Meterk (read my review).

An EMF Meter is the most valuable tool you will have in your arsenal when you are trying to reduce EMF radiation in your home. First, it will allow you to know how much, and what kind of EMF radiation is being emitted. More importantly, though, it will allow you to know if your efforts to reduce radiation are working by allowing you to test before and after.

To test the radiation of your TV, I would first measure near the television with it turned off. This will give you a baseline reading, to begin with. I would then turn the TV on, and give it a few minutes to boot up and connect to any services it is going to connect with.

After the TV has had a chance to boot up, I would test each type of radiation, Radio Frequency (microwave), Electric, and Magnetic. If you have the TriField TF2, you can do this by simply turning the dial. This will give you a full picture of how much EMF radiation your TV is emitting.

As you can see, if you’re sitting directly in front of your television, you will be exposed to a moderate amount of radiation, but if you move just a few feet back, you will reduce this to almost nothing.

Finally, consider getting a dirty electricity filtration system for your home. You would be surprised at just how much EMF radiation is being emitted from the dirty electricity in the electrical lines of your home. Check out this guide to learn a ton more about this.

Anti-glare filters are designed to help relieve eyestrain, fatigue, headaches and the stress associated with continued viewing of computer monitors by reducing glare. Anti-radiation filters help eliminate exposure to radiation emissions. Some products provide both anti-glare and radiation protection. These types of products can also be found at office supply stores.

Some filters are designed to hang over or attach to the top of the monitor. Other filters are made of a thin film that attaches directly to the screen surface.

Research studies carried out for decades have not solved the problem of the effect of electromagnetic radiation of various frequency and strength on the human organism. Due to this fact, we decided to investigate the changes taking place in human blood platelets under the effect of electromagnetic radiation (EMR) emitted by LCD monitors.

The changes of selected parameters of oxygen metabolism were measured, i.e. reactive oxygen species concentration, enzymatic activity of antioxidant defence proteins - superoxide dismutase (SOD-1) and catalase (CAT) - and malondialdehyde concentration (MDA). A suspension of human blood platelets was exposed to electromagnetic radiation of 1 kHz frequency and 150 V/m and 220 V/m intensity for 30 and 60 min. The level of changes of the selected parameters of oxidative stress was determined after the exposure and compared to the control samples (not exposed).

The findings indicate that exposure to electromagnetic radiation of 1 kHz frequency and 150 V/m and 220 V/m intensity may cause adverse effects within blood platelets" oxygen metabolism and thus may lead to physiological dysfunction of the organism.

There are way too many monitor-related myths floating around, probable because monitor technology has advanced so quickly over the years. For example, "sit at arm"s length distance" and "screen radiation causes cancer" have both been debunked.

As it turns out, there"s yet another myth that no longer holds true: the myth that black screens conserve more energy. This just isn"t true for LCD monitors, and it hasn"t been for quite a while.

LCD screens, on the other hand, produce light all the time. When an LCD screen needs to produce a black pixel, it just blocks the light from being shown and energy is being spent no matter what. In fact, on thinner LCD models, black screens actually end up using more energy!

Man cannot escape exposure to some radiation. We are surrounded by natural radioactivity in the earth and by cosmic rays from outer space. This is called background radiation and cannot be controlled. We are also exposed to manmade radiation, which can and must be controlled.

Much of the manmade radiation people are exposed to comes from electronic products. These include diagnostic x-ray machines, television sets, microwave ovens, radar devices, and lasers. In some cases, as with diagnostic x-rays, radiation emitted from these devices is intentional and serves a useful purpose. In others, as with TV sets, radiation emitted is not intentional and is not essential to the use of the product.

X-rays may be produced when electrons, accelerated by high voltage, strike an obstacle while traveling in a vacuum, as in a TV containing a cathode ray tube (CRT). Since many of the components in television sets operate at thousands of volts, there is the potential for x-ray generation. These components may produce x-rays capable of escaping from the television receiver or CRT. This unintentional emission of x-radiation can pose a potential hazard and must be controlled.

Scientists have not identified specific health effects resulting from exposure to extremely low doses of low-level radiation over prolonged periods of time. However, the current assumption is that there is no threshold of exposure below which x-radiation may not adversely effect human health. It is advisable, therefore, that x-radiation from TV sets, as well as other commonly used electronic products, be kept as low as reasonably achievable. It was for this purpose that Congress enacted the Radiation Control for Health and Safety Act of 1968 (currently called Federal Food, Drug, and Cosmetic Act – Subchapter C – Electronic Product Radiation Control).

It should be emphasized that most TV sets have not been found to give off any measurable level of radiation, and there is no evidence that radiation from TV sets has resulted in human injury.

The Food and Drug Administration (FDA) has the responsibility for carrying out an electronic product radiation control program mandated by the Electronic Product Radiation Control provisions of the Food Drug and Cosmetic Act. Through it"s Center for Devices and Radiological Health, FDA sets and enforces standards of performance for electronic products to assure that radiation emissions do not pose a hazard to public health.

A Federal standard limiting x-ray emissions from TV receivers to 0.5 milliroentgen per hour (mR/hr) was issued on December 25, 1969. The standard is applicable to all TV sets manufactured after January 15, 1970. The overall effect of the standard is to require that TV receivers must not emit x-radiation above the 0.5 mR/hr level when tested under adverse operating conditions. Test conditions do not represent normal use and ensure that when used under normal conditions, TV sets do not pose a radiation hazard.

Manufacturers of television receivers and computer monitors contain CRTs must certify that their products meets performance standard under Title 21 of the Code of Federal Regulations (CFR) Part 1020.10. All TV manufacturers must submit written radiation safety reports to FDA outlining how they assure that each set coming off the assembly line complies with the Federal x-ray radiation limit. These reports contain a description of the manufacturer’s quality control and testing program and the television radiation safety design. Manufacturers also must maintain records of test data and prepare an annual report to FDA summarizing these records. The FDA has the authority to ask for radiation safety data including results of x-ray leakage from selected sets to determine compliance with the standard.

X-radiation emissions from properly operated TV sets and computer monitors containing CRTs are well controlled and do not present a public health hazard. The FDA standard, and today’s technology, such as electronic hold-down safety circuits and regulated power supplies, have effectively eliminated the risk of x-radiation from these products. FDA has not found TVs that violate the standard under normal (home) use conditions.

It is important to note also that flat panel TVs incorporating Liquid Crystal Displays (LCD) or Plasma displays are not capable of emitting x-radiation. As such these products and are not subject to the FDA standard and do not pose a public health hazard.

Computer screens and television sets work similarly, producing both electric and magnetic fields at various frequencies. Screens with liquid crystal displays (LCDs) don’t produce significant electric and magnetic fields.

For this reason, modern TVs, which generally use LCD, LED, or plasma screens, emit only small amounts of radiation. But it’s enough that you should keep children from getting too close. Watching from a couch several feet away is thought to pose little danger.

Microwave ovens are considered to be safe if you use them correctly. People have experienced burns and other injuries from microwave radiation and superheating, but mostly from misuse.

You also get short-term high exposures when you are near electrical appliances like refrigerators, microwaves, and washing machines. The EMF radiation drops off sharply as you move away from these appliances.

Older camera lenses: some camera lenses from the 1950s-1970s incorporated thorium into the glass, allowing for a high refractive index while maintaining a low dispersion. The health risk from using older camera lenses is low; the radiation received when using a thoriated lens camera is approximately equal to natural background.

Gas lantern mantles: older, and some imported, gas lantern mantles generate light by heating thorium (primarily thorium-232). Unless gas lantern mantels are used as the primary light source, radiation exposure from thorium lantern mantles is not considered to have significant health impacts.

Televisions and monitors: Flat-screen televisions and monitors (e.g., LCD, OLED, plasma) do not use cathode ray tubes (CRTs) and therefore do not produce ionizing radiation. Older televisions and computer monitors that contain CRTs may emit x-rays. X-ray emissions from CRT monitors are not recognized as a significant health risk.

Sun lamps and tanning salons: the ultraviolet rays from sun lamps and tanning salons are as damaging to skin as the ultraviolet rays of the sun. In fact, warning labels are required which begin "DANGER—Ultraviolet radiation". You can learn more about performance standards for these devices from the Food and Drug Administration (FDA).

Glass: glassware, especially antique glassware with a yellow or greenish color, can contain easily detectable quantities of uranium. Such uranium-containing glass is often referred to as canary or vaseline glass. In part, collectors like uranium glass for the attractive glow that is produced when the glass is exposed to a black light. Even ordinary glass can contain high-enough levels of potassium-40 or thorium-232 to be detectable with a survey instrument. However, the radiation received when using glassware – even canary or vaseline glass – is unlikely to exceed background radiation levels.

EXIT signs: Some EXIT signs contain the radioactive gas called tritium, allowing them to glow in the dark without electricity or batteries. The tritium used in EXIT signs gives off low-level beta radiation, causing a light-emitting compound to glow. Tritium EXIT signs do not pose a direct health hazard, as the beta radiation can be stopped by a sheet of paper or clothing. However, tritium EXIT signs must not be disposed of in normal trash. For more information on tritium EXIT signs, see the Nuclear Regulatory Commission’s page on tritium EXIT signs.

Does not normally occur at 100% brightness level. At levels below 100% flicker often occurs with frequencies between 60 and 255 Hz, since often pulse-width modulation is used to dim OLED screens.

No native resolution. Currently, the only display technology capable of multi-syncing (displaying different resolutions and refresh rates without the need for scaling).Display lag is extremely low due to its nature, which does not have the ability to store image data before output, unlike LCDs, plasma displays and OLED displays.
