5.5.2 Ultraviolet Radiation. UV is an invisible electromagnetic radiation characterized by the wavelength ranging from 100–400 nm. In the electromagnetic radiation spectrum, it is located between the ranges of a visible violet radiation and so-called soft X-rays. For therapeutic purposes, the UV wavelength range of 200–400 nm is used. Physical characteristics of artificial light sources. 3.3.1. Physical principles. Light is electromagnetic (EM) radiation in the range from 400 to 780 nm (1 nm is 10-9 m) that is visible to the intact adult human eye (see also CEI/IEC 62471/2006). The safe use of non-coherent artificial UV radiation sources in buildings under the authority of the University of Toronto is covered by the Ultraviolet Radiation Safety Program. The University of Toronto is committed to ensuring that the use of UV radiation sources is carried out safely with due regard for employees, students, the public and Feb 26, 2015 · Artificial sources of radiation: lamps. Although the intensity of ultraviolet radiation is, in general, larger in the outdoor environment, the radiation penetrating through the windows and the radiation emitted by artificial lighting, generally available indoors, may potentially exert long-term effects 11. Oct 11, 2023 · Sources of UV Light. UV light comes from a variety of sources, both natural and artificial. Natural Sources of UV Light: The sun: The sun is the most abundant source of UV light on Earth. It emits all three types of UV rays: UVA, UVB, and UVC. However, most of the UVC rays are absorbed by the Earth's atmosphere, so they do not reach the ground. covering ultraviolet (UV) radiation, visible light and infrared radiation. Any man-made source of light, whether visible or invisible, is considered to be artifi cial optical radiation. Offi ce lighting, computer displays, blowtorches, welding arcs and stage lighting are all examples of typical artifi cial optical radiation sources. Sep 14, 2020 · UVC is the shortest wavelength of the three forms of UV. The shorter the wavelength, the more harmful the UV radiation. However, lucky for us, UVC isn't able to penetrate earth's atmosphere. So while UVC is the most dangerous because it's the shortest wavelength, it's not a risk to the typical person because the sun's natural UVC emissions don Artificial sources of radiation: lamps. Although the intensity of ultraviolet radiation is, in general, larger in the outdoor environment, the radiation penetrating through the windows and the radiation emitted by artificial lighting, generally available indoors, may potentially exert long-term effects 11.
