TVs are becoming a staple in every American household. They’re beloved for their detailed, bright, and vibrant display.
Smart TVs also make it easy to stream your favorite shows or connect to other devices, thanks to wireless connections.
However, there may be nagging thoughts in your mind –– are TVs harmful, and does it cause cancer?
Well, the truth is that all televisions emit radiation to some degree, particularly radio frequency (RF) and electromagnetic field (EMF) radiation.
TVs emit only low-frequency radiation at close range and prolonged exposure.
While TVs emit radiation, the good news is that TVs do not cause cancer.
The low levels of radiation given off by TVs pose little to no harm.
This article will cover how TVs emit EMF radiation and what you can do to minimize exposure.
Let’s get started!

So Modern Television Sets Emit Radiation?
The amount of radiation emitted by modern televisions depend on the following:
- Kind of TV
- Screen resolution
- Size of the display
- Hours of use
Compared to older cathode ray tube (CRT) monitors, modern TVs emit lower levels of electromagnetic radiation (EMF) and radio frequency (RF), except at close range and with prolonged exposure.
Since most modern TVs also have smart features, they need to connect to the internet using WiFI.
Smart TVs will constantly send signals to connect to a WiFi network.
Users are exposed to higher levels of radio frequency (RF) signals.
Unfortunately, this feature can’t be turned off even if your smart 4K TV is switched off.
However, when we weigh the pros of getting a smart TV, we can’t help but think that keeping one at home is the right choice.
That’s because of the following:
- Streaming movies from Netflix, Hulu, Amazon Prime
- Accessing social media sites
- Controlling other wireless devices
- Voice control
On top of that, WiFi networks also emit EMF radiation. If your WiFi and other electronic gadgets are switched on 24/7, you are exposed to higher levels of EMF radiation from the WiFi router.
Lastly, some smart TVs like the LG Nanocell 75 have a Bluetooth function that sends signals for connection to other wireless devices.
Bluetooth connection is incredibly convenient, especially for connecting your sound system.
While Bluetooth signals are weaker than WiFi signals, you expose yourself to additional radiation.
Sitting Too Close to the TV
Modern TVs, including LED, LCD, and plasma, emit EMF radiation in all directions up to 12 feet. This means that the screen isn’t the only component that gives off radiation –– simply sitting close to the electrical system will expose you to EMF radiation.
A big factor to consider when figuring out how far you should be from a TV depends on the following:
- Type of TV
- Screen resolution
- Screen size
The ideal viewing distance for HD TVs is at least three times the height of the TV.
For modern TVs, you need to stay at a distance of at least 1.5 times the TV to minimize EMF exposure.
Sitting at an appropriate distance from your TV should eliminate any worry about being exposed to harmful radiation.
Watching TV for Too Long
Spending too much time in front of the TV also exposes you to more radiation, so think twice about binge-watching your shows the whole day!
Especially if you have children at home, be careful about how much TV they consume. According to a study, children are more susceptible to EMF radiation because their brains are still developing.
How Do Modern TVs Emit EMF Radiation?
Although minimal, modern TVs emit EMF radiation in three ways:
1. Radiation from the Circuitry
All electronic devices with a circuit board emit EMF radiation to some degree. These include microwaves, computers, laptops, refrigerators, and even washing machines. On that note, it might be best to accept that almost all home appliances emit radiation.
However, you shouldn’t be too troubled. Simple appliances and television sets only emit a small amount of radiation.
2. Electricity Radiation from the Converter
Most electronics today require a lower or higher voltage than the standard 50/60 Hz, interrupting the smooth flow of AC electricity and generating electrical spikes and surges. When there are electrical spikes or surges, dirty electricity spreads through wiring and power lines.
As dirty electricity travels through these lines, it releases harmful EMF radiation into the surrounding environment.
To reduce your exposure to EMF, you can plug in dirty electricity filters around your home.
To figure out how many filters you might need, you will need to measure EMF with an EMF pollution monitor .
3. Radio Frequency Radiation
As we mentioned, smart TVs have built-in components that send signals for WiFi and Bluetooth.
Since smart TV features require the continuous transfer of a lot of data, TVs also emit radio frequency radiation, which can be harmful at high levels.
How Much Radiation Does a Television Emit?
The actual amount of radiation emitted by modern TVs will depend on many factors, including the brand, type of TV, build quality, TV size, and smart functionalities.
Thankfully, it’s possible to measure exactly how much EMF radiation you’re exposed to with the help of an EMF meter.
Good quality EMF meters can accurately tell you:
- How much EMF radiation is emitted
- What kind of EMF radiation is emitted
We always recommend the Trifield TF2 EMF meter because it’s user-friendly, durable, and very accurate.
Almost every household today has a modern television set. But is this device safe to have at home?
Modern television sets have not been proven to emit harmful radiation levels, much less enough radiation to cause cancer.
Compared to older cathode ray TVs, modern TVs emit negligible amounts of EMF radiation.
Especially if you take necessary precautions such as limiting the time you watch TV, sitting at a distance, and limiting the time your WiFi is on, you can minimize the risk of exposure to EMF radiation.
