Perhaps you are after the word band or bandwidth.
"Radio" is the name we give to a section of the electromagnetic spectrum, so it can include whatever wavelengths we decide to use that name for. Radio is generally considered to be everything in the electromagnetic spectrum with wavelengths of one millimeter or longer, corresponding to any frequency up to 300 GHz.
The (not surprising) name is "visible light."
"Gamma" is the name given to the electromagnetic radiation with the highest frequency (shortest wavelength, highest energy).
Electromagnetic spectrum is the range of wavellengths of different radiations reflected or emitted by objects with temperature above 0 k. Remote sensing technology make use of such radiations of certain wavelength in EM spectrum to distinguish different objects as different object radiates differently.
The electromagnetic (EM) spectrum is the entire range of frequencies that electromagnetic radiation can have. The EM spectrum is divided into sections based on the common characteristics that certain frequency ranges have. These sections are, in order from low to high frequency, radio waves, microwaves, infrared waves, visible light (which from low to high frequency is further divided into red, orange, yellow, green, blue, indigo, and violet), ultraviolet waves, X-rays, and gamma rays. You can think of the EM spectrum as an invisible rainbow with visible light being a small part of it. And, like a rainbow, the edges of the divided sections are blurry; i.e. there is no exact frequency where one can say, for example, that this wave is no longer an X-ray, but is instead a gamma ray. it is waves of light in order of their wavelengths and frequencies APEX: A chart of frequencies of light waves.

the visible light spectrum
The electromagnetic spectrum is the name for the range of electromagnetic waves when they are placed in order of increasing frequency. The electromagnetic spectrum is made up of radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays.

You're free to give it any name that appeals to you. It's most commonly called the "electromagnetic spectrum" by others.
