The 75 pages that link to Ultraviolet, each with the reason it gives.

• Electromagnetic spectrumBroader topic: It lies just beyond visible light and can trigger chemical and biological effects.

• Visible spectrumCompared with: It borders the short-wavelength edge but is generally invisible to humans.

• CarcinogenBroader topic: Ultraviolet exposure damages skin-cell DNA and contributes to skin cancers.

• MelaninRelated: Melanin absorbs and scatters some ultraviolet radiation, reducing its penetration into tissue.

• OzoneRelated: Ozone absorbs ultraviolet radiation, while ozone depletion increases surface exposure.

• Ozone depletionRelated: Ultraviolet light releases reactive chlorine from stable compounds and also photolyzes ozone.

• Ozone layerRelated: Ozone absorbs much of the Sun’s biologically harmful ultraviolet radiation.

• X-rayCompared with: Ultraviolet photons generally have lower energies and longer wavelengths than X-rays.

• ChlorofluorocarbonRelated: Ozone loss from CFCs allows more harmful ultraviolet radiation to reach Earth's surface.

• DNA damageRelated: It can create covalent links between neighboring DNA bases.

• SunscreenNarrower topic: Sunscreen is designed to reduce exposure to ultraviolet wavelengths reaching the skin.

• CarcinogenesisRelated: UV exposure can damage DNA in skin cells and initiate tumor development.

• MelanomaRelated: UV exposure damages DNA in skin cells and is a major preventable melanoma risk.

• PhotoprotectionNarrower topic: Ultraviolet radiation is a major source of harmful exposure addressed by photoprotection.

• Skin cancerRelated: UV exposure damages skin-cell DNA and drives many skin cancers.

• Antarctic ozone holeRelated: Returning sunlight photolyzes chlorine compounds and starts rapid ozone-destroying reactions.

• CyanotypeNarrower topic: Its energy drives the sensitizer’s photochemical reaction.

• PhotobleachingRelated: Its higher-energy photons can initiate pigment damage and accelerate bleaching.

• InfraredCompared with: Ultraviolet lies on the higher-frequency side of visible light, opposite infrared.

• Radio waveCompared with: Its shorter wavelengths and greater photon energies mark a sharp contrast with radio waves.

• ErgosterolRelated: Ultraviolet radiation initiates the ring-opening reaction that converts ergosterol toward vitamin D₂.

• MelanogenesisRelated: UV exposure triggers cellular signals that increase pigmentation in skin.

• PhotodegradationRelated: Ultraviolet photons commonly initiate degradation in materials exposed to sunlight.

• StratosphereRelated: Ultraviolet absorption by ozone supplies much of the stratosphere’s distinctive heating.

• Ultraviolet germicidal irradiationNarrower topic: Germicidal irradiation is one use of ultraviolet radiation.

• MelanosomeRelated: Melanin packaged in melanosomes absorbs and disperses some ultraviolet radiation.

• Ozone holeRelated: Less stratospheric ozone allows more harmful ultraviolet radiation to reach the surface.

• Fluorescent lampRelated: The lamp’s discharge produces ultraviolet wavelengths that the phosphor absorbs.

• MutagenesisRelated: UV can form DNA photoproducts that lead to mutations when replication or repair is inaccurate.

• Stellar flareRelated: Flare ultraviolet output can drive photochemistry in nearby planetary atmospheres.

• SunburnNarrower topic: UVA and UVB wavelengths reach skin and drive most sunburn reactions.

• Basal cell carcinomaRelated: UV exposure causes DNA damage that contributes to tumor formation.

• EumelaninRelated: Eumelanin absorbs part of this radiation, reducing its penetration into tissue.

• Ozone–oxygen cycleRelated: Different ultraviolet wavelengths drive oxygen and ozone photodissociation.

• PhotosensitivityRelated: UVA and UVB wavelengths trigger many photosensitive skin reactions.

• Photosynthetically active radiationCompared with: It falls below PAR's conventional wavelength range, though it can affect photosynthesis and plant physiology.

• Solar radiationBroader topic: The Sun emits ultraviolet radiation that affects chemistry and living tissue.

• SunglassesRelated: Sunglasses may absorb ultraviolet wavelengths that can injure eye tissues.

• Ultraviolet indexNarrower topic: The index summarizes the ultraviolet radiation reaching the ground.

• Ozone-depleting substanceRelated: Thinner ozone allows more harmful ultraviolet radiation to reach Earth’s surface.

• PheomelaninRelated: It can damage skin and interact differently with pheomelanin than with eumelanin.

• PhototherapyNarrower topic: Many dermatologic treatments use carefully controlled ultraviolet wavelengths.

• Radiation-induced cancerCompared with: Ultraviolet light causes skin cancers but is non-ionizing, unlike the radiation considered here.

• Squamous cell carcinomaRelated: UV exposure damages DNA in skin cells and is a major cause of cutaneous cases.

• Atmospheric absorptionRelated: Absorption by ozone and oxygen limits how much ultraviolet radiation reaches the surface.

• Excimer laserNarrower topic: Excimer lasers emit in this spectral region, which governs their optical and material interactions.

• F. Sherwood RowlandRelated: Stratospheric ultraviolet radiation breaks down CFCs and also makes ozone depletion a biological concern.

• Mario MolinaRelated: Solar ultraviolet radiation breaks apart chlorofluorocarbons high in the atmosphere, releasing reactive chlorine.

• ThymineRelated: Ultraviolet exposure can link adjacent thymines and damage DNA.

• Anders Jonas ÅngströmRelated: Ångström’s studies included ultraviolet wavelengths beyond ordinary vision.
