Description
[edit | edit source]
UVR is a non-ionizing radiation and lies between soft x-rays and visible light in the electromagnetic spectrum. It has a wavelength of 100 to 300/480 nm. The wavelengths are classified by International Commission on Radiation (CIE)[1] on the basis of dominant biological effects displayed by each region.
UV - A 315 - 400 nm Encourage wound healing
UV - B 280 - 315 nm Skin erythematous region
UV - C 100 - 280 nm Germicidal region
Ultraviolet radiation obeys the law that governs all the radiations, they may reflect, scatter and are absorbed by molecular chromophores. The degree of absorption is generally greater for shorter wavelengths, shorter wavelengths penetrate less deeply. Absorption depends on the thickness of the epidermis and any pigmentation of the skin. Skin thickening due to lesions will result in increased scattering and absorption and thus reduced penetration.
