Ultrafiolett stråling kan deles inn i vakuum UV:100-200 nm, fjernt UV:200-300 nm og nært UV :300-400 nm. En annen mye brukt inndeling er (bølgelengde i nanometer (nm, 10-9 meter)):. UV A: 315 - 400 n Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays.UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.It is also produced by electric arcs and specialized lights, such. Ultrafiolett stråling (forkortes UV-stråling) er elektromagnetisk stråling med kortere bølgelengde enn synlig lys (bølgelengder mellom 10 - 400 nm).. UV-stråling deles inn i en rekke underområder ifølge ISO standard ISO-21348: Områdene nærest synlig lys er UVA, UVB, UVC og vakuum-UV, hvor sistnevnte vanligvis bare forekommer i vakuum

  3. No UV‐induced immunosuppressive effects were observed in Xpa‐knockout mice after 222‐nm UVC irradiation (Fig. 7), while suppression was observed after broad‐band UVB exposure. In a report from the 1960s, the required 222‐nm UVC dose to produce erythema in rabbit skin was estimated to be 0.5 kJ m −2
  4. UV-stråling. Ozonlaget beskytter jorda mot skadelig ultrafiolett stråling (UV-stråling) fra sola ved å absorbere sollys med en bølgelengde mellom 290 og 320 nanometer. Spekteret av solstråling opp til 320 nanometer kalles UV-B, og det er denne strålingen som gjør at vi blir solbrent

Nanometer er en måleenhet for lengde. En nanometer er det samme som en milliarddels meter. Symbolet for nanometer er nm. Ordet nanometer er sammensatt av nano og meter. Meter er grunnenheten for lengde i SI-systemet. Nano er et prefiks som betyr at enheten skal divideres med 1 000 000 000 (109). En slik sammensetning av en enhet og et prefiks kalles i SI-systemet en multippelenhet A nanometer is equivalent to one billionth of a meter. An in vitro experiment by HU researchers showed that 99.7% of the SARS-CoV-2 viral culture was killed after a 30-second exposure to 222 nm.

UVC This is the shortest (weakest) UV wavelength for use in non-vacuum environments. UVC spans the 200 to 280 nm range but is generally measured in the 250 to 260 nm range because this is the most powerful output area of UVC UV-Visible Absorption Spectra. To understand why some compounds are colored and others are not, and to determine the relationship of conjugation to color, we must make accurate measurements of light absorption at different wavelengths in and near the visible part of the spectrum
