Firstly, any form of radiation is harmful to the body because it causes cellular aberrations and genetic mutations which may ultimately lead to cancer. As for sun radiation, so long as you don't get yourself too overexposed there's really nothing to worry about. in fact the sun is helpful in the activation of vitamin D. just a tip, the best time to go out for a little sun would be early in the morning and later in the afternoon. However, staying in the sun for too long over the years without wearing a hat, suncreen, sunglasses, protective clothing or staying in the shade can increase your risk of getting skin cancer.
Did You Know: Getting sunburnt 5 times each Summer increases your risk of skin cancer by 10%
the disadvantages of radio waves are:
radioationalong with xrays are very well som what bad for you, because the ultra violet rays that are shown of the light or heat can wear down our body. That is why when you get an x ray people wear the covers
radiation is dangerous and not dangerous
first its dangerous because if you tough it with a bare hand you can get "leukaemia" (cancer of the white blood cells)
and the good thing is that we have radiation in smoke alarms and that does not harm us and if it did i think i would rather have radiation in my smoke alarm then burn to death without one :) x

They can harm you if you use phones too much radiation comes of the phone and can hurt you.
No it is not bad for your health.
radio waves
light waves do not need a medium. Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters/sec in a vacuum.
Radio waves. Low frequency.
A triode works as a basic amplifier by the use of radio waves. The radio waves produce a heat that is amplified.
That means that both the frequency and the wavelength of microwaves are also between those of infrared and radio waves.
Here are a few things that radio waves can do: 1. Communications (TV, Commercial radio, Ham radio etc.) 2. Heat things up, (Microwaves are just extremely short radio waves) 3. They can travel extremely fast (At the speed of light)
Not very. As far as I know there's no real evidence that radio waves cause any measurable harm to people.
they use radio waves to pick up some what satellite images or existance of things in space
Not Really Broadcasting Republican Propaganda
no, mechanical waves are not radio waves
Transverse. Radio waves are electromagnetic waves, which are transverse.
The're really low frequency and can be easily disrupted by buildings and things like that. AM radio uses these electromagnetic waves to broadcast stuff.
Radio waves ARE electromagnetic waves.
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.
by changing the amplitude or frequency of the radio waves.
Radio waves are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum.
it causes gamma waves ,visible light ,radio waves.
