Electromagnetic radiation is a form of energy exhibiting wave-like behavior as it travels through space.
The electromagnetic spectrum, in order of increasing frequency and decreasing wavelength, consists of radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
Communication Technology
In Australia communication utilities may install and operate communication equipment on Council infrastructure such as water towers. Council workers responsible for the maintenance of structures supporting or containing communication equipment need to be aware of the possibility of exposure to high levels electromagnetic radiation in the immediate vicinity of these devices.
