A tunawa da makamashi, wanda aka kasaftawa hasken ultraviolet, za a iya amfani da a watse rauni shaidu daga sunadarai na gina jiki. Wannan tsari shine ake kira photolysis. Its kwarara yana tare da a saki aiki abubuwa a ƙarƙashin rinjayar matsakaici kalaman ultraviolet sakawa a iska mai guba.

Short-kalaman effects tsokani da denaturation na gina jiki polymer, wanda, da rasa da aiki, precipitate. Hasken ultraviolet da musamman tasiri a kan cikin jigidar halittar DNA. Ƙarƙashin rinjayar take hakkin ya lura maimaitawan na DNA da cell division. A lokaci guda, hasken ultraviolet sa oxidative wulakanci ne a gina jiki Tsarin. Wannan take kaiwa zuwa cell mutuwa. Amma lalace kernels suna da ikon mayar da (duhu gyara). Wannan shi ne zai yiwu a ƙarƙashin rinjayar tsawo-kalaman UV radiation da bayyane haske makamashi. A cikin wadannan matakai, wasu enzymes masu shiga.

The duhu da photo-amsawa gyara kasance a cikin category na m-Na'urar halayen. Da suka sa yanayin jikin mutum da kuma samar da kariya daga kufan UV radiation.

Saboda haka, hasken ultraviolet ne canja pro-bitamin kunshe a cikin fata, a cikin bitamin D. iya shiga kawai daya cikin goma na wani millimeter, daukan hotuna na samar da samuwar babban adadin kuzari a kwatanta da sauran electromagnetic taguwar ruwa na infrared da bayyane bakan.

Photolysis, kuma denaturation ne a cikin spinous Layer na fata. Tare da wannan ne yake aikata histamine saki, acetylcholine, biogenic amines. Wadannan mahadi tsokane ci gaban erythema. Yana auku bayan 2-8 hours. gina jiki bazuwar kayayyakin taimako zuwa ga fadada daga jini, da hijirarsa daga fari da maikacin jini, kumburi da fata. Duk wadannan mamaki suna da rikitarwa fata hangula rabe viscera rabe da abin da ya faru neuroreflex halayen. A lalata kayayyakin diverge ta cikin jini, samar da humoral tasiri. Ultraviolet sakawa a iska mai guba ga MW kewayon tsokane wani aseptic kumburi martani a cikin fata. By rana ta biyu da ta kai ta matsakaicin. A rana ta bakwai, da rana ta tara ga kumburi amsa wuce, maimakon tan bayyana. Short kalaman radiation hanzari tsokane erythema, barin wani m pigmentation.

Matsakaicin chromogenic shafi dogon-kalaman UV haskoki. A melanoblast dake a cikin muhimmi Layer na epidermis, daga tyrosine, da kuma lalata kayayyakin adrenaline dihydroxyphenylalanine kafa melanin. Ya (melanin) giant kwayoyin hana ingress zurfi a cikin dermis da wani ɓaɓɓake daga sunadarai na gina jiki halaka su da UV radiation. Bugu da kari, da melanin kwayoyin sha infrared haskoki da bayyane bakan. Saboda haka, cikin fata da aka kare daga zafi fiye da kima da kuma kona. A yankunan da tasiri na hasken ultraviolet ne ta ƙara Lymph da jini ya kwarara da aka inganta cover farfadowa, ta ƙara kira na collagen zaruruwa. Lokacin da m erythema sunã gudãna Littafi faruwa sa samun abinci da kuma chronically kumburi tafiyar matakai.

Ultraviolet daukan hotuna ne yadu amfani a cosmetology. Saboda haka, a cikin solarium ne santsi da kuma kyakkyawan tan. Yana amfani da dogon-kalaman haskoki, yayin da short-da matsakaici-radiation a tanning gyaran gashi ne tacewa.

Ya kamata a lura cewa wuce kima daukan hotuna zuwa da rana zai iya kai wa ga bai kai ba tsufa, wani karu a elasticity na fata. Bugu da ƙari kuma, shi iya kunna ta da samuwar free radicals da taimakawa wajen ciwon daji.

Don sanin line tsakanin "cutarwa" da "m" yana amfani da rãnã UV index. Wannan siga nuna matakin na radiation a Duniya.
