UV radiation comes in a variety of forms

Sunlight is the most prevalent source of UV radiation, and it emits three types of UV rays: As a result, the vast majority of UV rays you encounter are UV-A, with only a trace of UV-B. Like all forms of light on the electromagnetic spectrum. UV radiation is categorised based on its wavelength. The distance between the peaks in a series of waves is described by wavelength. UV-B rays have a short wavelength that reaches the outer layer of your skin, while UV-C rays have a longer wavelength that can penetrate the middle layer of your skin. UV-C radiation has the shortest wavelength of the three and contains the most energy. The sun's radiation does not reach the earth's surface because it is obstructed by the ozone layer in the atmosphere. As a result, the only method for humans to be exposed is through an artificial source, such as a germicidal lamp. Show Less
