No it's a wave ther all around you at all times if they wher dangerous they would not be used in raidos

I would very much like to see you with greater frequency. What frequency will you be on? I can switch to another radio station by adjusting the frequency of my radio receiver.
In Epidemiology Absolute comparison indicates how much greater is the disease frequency in the exposed group , compared with non-exposed.
Radio waves. A bit higher in frequency than "radio", but not much.
Gamma rays have a much higher frequency then radio waves.
Not much. It wasn't radioactive, it couldn't do much but beep on a radio frequency.
Radio waves and ultraviolet waves are the same physical phenomenon.The difference is that radio waves have a much greater wavelength.(That's equivalent to saying that they have a much lower frequency.)
The difference between a radio wave and a x-ray is the fact that x-rays have a much higher frequency. Since higher frequency means more energy in electromagnetic waves, x-rays can be used for purposes such as taking photos of things inside the body. Radio waves are at a lower frequency and have a much longer wavelength. They are used in radio, television, and communication.
Both gamma rays and radio waves are part of the electromagnetic spectrum, but gamma rays are much higher frequency (shorter wavelength) than radio waves. Visible light is lower frequency than gamma and higher than radio.
The RFID chip is a Radio Frequency IDentification chip. When it receives a radio wave in the right frequency range, it sends back a characteristic radio signal which allows it to be specifically identified, much like a bar code would when optically scanned.
Because the X-ray has a shorter wavelength (kuch shorter!) the energy is much greater in an X-ray. Therefore with a bigger energy, E = hv would calculate a higher frequency for x rays. As the eregy of a wave increases, so goes the frequency. Actually, it probably should be stated the other way, but I still have answered your question
The radio wave part of the spectrum is very wide. The extreme ends are, roughly,15km ( used for communicating with submerged submarines)1 mm ( used for research, and possibly for radar)The visible spectrum covers only a 2:1 range of wavelengths. It is centred on the colour yellow, with a wavelength ~= 700nm.The very shortest of the radio waves is about 1000 times as long as yellow light.
