In the sense that TVs must radiate photons in at least the visible light spectrum for you to even see what's on the screen, yes, they're radioactive. However, very, very little of this radiation is ionizing radiation (x-rays, gamma rays, beta rays, etc.), and thus is completely harmless to you. The dust collected on the TV's screen because of its static electrical field does have slight amounts of ionizing radiation though, because some of that dust is the naturally produced, radioactive isotope, 222Rn, that's always floating around in the background. Also, if your TV is very old, its X-ray shielding could be compromised, and thus could give you a very small, pretty-much harmless dose of X-ray radiation if you were sitting less than two inches from the screen.

∙ 11y agoAnalog Television use radio waves both for audio and video. Video circuit is much more complex than audio circuit. Ancient Televisions used CRT (Cathodic rays tube) in wich a powerful valve emmits electrons towards the inner side of the screen, and the result is the image saw by the TV watchers. The TV station broadcasts electromagnetic waves to the TV receiver which use the same radio waves to transform audio and video onto images and sound through complex electronic circuits.

Flat screens TVs produce negligible radiation less than 20 milligauss. The box -shaped TVs produce much higher radiation, and could reach 300 milligauss (depend on quality of manufacturing). Most standards recommend less than 200 miliigauss for safety. Radiation is inversely proportional to distance. Don't let children sit close to TVS.

What humans use radio waves?
Radio waves are used to transmit signals from a radio station, and you can receive the signals with a radio, and hear them as sound such as speech or music. The long wavelength of radio waves makes them a suitable medium for transmitting over a large range. it is also use in agriculture...... it is used to diagnose different diseases
Radio signals are broadcast by what waves?
Radio waves are electromagnetic waves. Electromagnetic waves include waves such as X rays, ultraviolet light, visible light, infrared rays and so on, but you probably imagine radio waves to be quite different from these waves. Of the various kinds of electromagnetic waves, radio waves have a longer wave length than infrared rays, and are defined by the Radio Law as 'electromagnetic waves with a frequency of less than 3,000 GHz (3 THz)'Ultralow frequency radio wavesbelow 3kHzradio waves3kHz~3THz infrared rays3THz~380THz visible light380THz~790THz ultraviolet light790THz~105THz X rays105THz~107THz γ raysabove 107THzNames of radio waves Frequency Wave length Principal applications VLF(Very Low Frequency) 3kHz ~ 30kHz 100km ~ 10km LF(Low Frequency) 30kHz ~ 300kHz 10km ~ 1km Vessel / Airplane beacon MF(Medium Frequency) 300kHz ~ 3MHz 1km ~ 100m AM radio, Marine radio, Amateur radio HF(High Frequency) 3MHz ~ 30MHz 100m ~ 10m Shortwave broadcasting, Marine / Air radio, Amateur radio VHF(Very High Frequency) 30MHz ~ 300MHz 10m ~ 1m TV, FM, Fire radio, Police radio, Disaster PA radio network UHF(Ultra High Frequency) 300MHz ~ 3GHz 1m ~ 10cm Low power radio, Mobile-phone, Taxi radio, Amateur radio, TV, Wireless LAN SHF(Super High Frequency) 3GHz ~ 30GHz 10cm ~ 1cm Satellite broadcasting, Radar EHF(Extremely High Frequency) 30GHz ~ 300GHz 1cm ~ 1mm Satellite broadcasting, Radio astronomy, Radar submillimeter waves 300GHz ~ 3THz 1mm ~ 0.1mm
Do computers use radio waves?
Absolutely. Computing is highly integrated into radio frequency (RF) type communications. Examples of RF integration include Bluetooth, WiFi, and RF peripherals such as the mouse and keyboard.
Are radio waves a form of sound or light?
When you listen to the radio, you are hearing sound, which has no resemblance to light, radio waves, or x-rays. However, the sounds you hear are created in the radio receiver, using information that was carried to your location by means of radio waves.
What are radiowaves and how they are formed?
Radio waves Radio waves are electromagnetic waves occurring on the radio frequency portion of theelectromagnetic spectrum.Discovery and utilizationRadio waves were first predicted by mathematical work done in 1865 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations, that described light waves and radio waves as waves of electromagnetism that travel in space. In 1887, Heinrich Hertzdemonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory. Many inventions followed, making practical the use of radio waves to transfer information through space. Nikola Tesla and Guglielmo Marconi are credited with inventing systems to allow radio waves to be used for communication.For more information go to:http:/en.wikipedia.org/wiki/Radio_waves
How are radio and television waves added to em radio waves?
by changing the amplitude or frequency of the radio waves.
Are Internet waves electromag?
By Internet waves, one would assume you mean WiFi. When talking about WiFi, it does not use electromagnetic waves but instead uses radio waves like your TV or radio does.
How are radio waves and television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
How are radio and television waves added to em waves?
by changing the amplitude or frequency of the radio waves.
Why does tv use radio waves?
because on the em spectrum, radio waves are the lowest. if a tv used a higher raadioactive source like uv and you were exposed to it to much (by watching to much tv) you could get cancer and die unfortunately.
How are radio television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
How does the sped of radio wave compare with speed of tv waves when both measured in vacuum?
Both radio waves and tv waves are electromagnetic waves. So both have the same speed in vacuum. Of course radio waves are of lower frequency compared to that of tv waves.
How do you people use radio waves?
Radio waves have the longest wavelengths in the electromagnetic spectrum. These waves can be longer than a football field or as short as a football. Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones
How do AM radio and television wavelengths compare with radar?
AM radio, FM radio, television, cellphones, GPS, and microwave ovens all use radio waves that are longer than the ones used for RADAR.
Is it true that radio waves carry information from a broadcasting station t your radio or television?
Is it true that radio waves carry information from a broadcasting station to your radio or television
What industrial applications have longitudinal waves?
Industries that have longitudinal waves are cell phones, radio stations, television stations, and other industries that use sound waves.
Are radar waves visible?
No. Radar waves are one category of radio waves. Think of all the radio waves that are all around you right now . . . AM radio, FM radio, police and fire radio, highway patrol radio, taxi radio, television picture and sound radio waves, cellphone radio waves, garage-door-opener radio waves, bluetooth radio waves, WiFi waves, microwaves ... and you can't see any of them ! Radar waves can easily be there in the group.
