Huwandu hwakasiyana hwemwaranzi kubva kuzuva hunosvika kupasi redu. Imwe yeaya mheni ndeye ultraviolet. Iye ultraviolet indekisi Icho chiyero chekusimba kwemwaranzi yeultraviolet iyo inokwanisa kusvika pasi repasi. Isu tinoziva kuti zuva rinoburitsa mwaranzi munzvimbo dzakasiyana-siyana dzemagetsi emagetsi. Kunyanya, inoburitsa yakanyanya kuwanda mwaranzi munzvimbo yeultraviolet. Iyi radiation inokosha zvakanyanya sezvo zvichidikanwa, asi zvakare ine njodzi.
Naizvozvo, isu tiri kuzotsaurira ichi chinyorwa kukuudza nezvese hunhu uye kukosha kweiyo ultraviolet index.
Mhando huru
Isu tataura kuti iyo ultraviolet index hapana chimwe chinopfuura chiyero chekusimba kwemwaranzi yeultraviolet iyo inokwanisa kusvika pasi repasi. Ose mwaranzi inoburitswa nezuva inopatsanurwa kuita zvikamu zvakasiyana zvemagetsi emagetsi. Ultraviolet radiation yakakamurwa kuita matunhu matatu zvichienderana nesimba rayo. Iwo akanyanya kusimba mwaranzi yealviolet anozivikanwa seUVC uye anoshanda kuma wavelengths anotangira pa100-280 nm. Iyo wavelength ye UVB mwaranzi iri pakati pe280-315 nm. Chekupedzisira, mwaranzi yeUVA ndiyo ine njodzi shoma, sekutaura, uye inosanganisira nzvimbo dzemagetsi emagetsi anotangira kubva pa315-400 nm.
Chikamu chinonyanya kukuvadza cheiyo ultraviolet radiation iUVC radiation. Neraki, ichi mwaranzi hachisvike pasi repasi sezvo chakaputirwa nemuchadenga medu. Kunyanya, chikamu chakakura chemwaranzi iyi chinopinda muozone layer. Zvisinei, UVB mwaranzi inopinza mudenga ne90% anenge. Kunyangwe maUVAs achinyudzwawo padiki padiki, chimwe chikamu chazvo chinosvika pamusoro pedu.
Isu tinoziva kuti mwaranzi yezuva yakakosha mukusimudzira kwehupenyu sekuziva kwedu. Izvo zvinofanirwa kuyeukwa kuti photosynthesis muzvirimwa inoitika nekuda kwechiito cheiyo ultraviolet mwaranzi uye vanhu vanofanirwa kuratidzwa nezuva kuti vagadzire vhitamini D muganda. Kushomeka kwevhitamini iyi mumuviri kunogona kutungamira mukushomeka kwemamineralization emapfupa. Naizvozvo, zvakakosha kuti sunbathe zuva rega rega kweinenge hafu yeawa. Nekudaro, kana isu tine kunyanyisa kuratidza kune ino yeawa ultraviolet mwenje inogona kukuvadza kune hutano. Uye ndeyekuti ultraviolet radiation inogona kukonzera kukuvara kune iyo collagen yeganda uye nekudaro kuwedzera kukwegura nguva isati yakwana
UV Index Index Kukuvadza
Iyo delta violet indekisi ndiyo ino pima urefu hwe hurefu uye huwandu uye kusimba kwemwaranzi ye ultraviolet iyo inokwanisa kusvika pamusoro penyika. Zvisinei, ultraviolet radiation inogona kukonzera kukuvara kweDNA uye shanduko. Pane humbowo hwakawanda kubva kuzvidzidzo zvinoratidza kuti inogona kuwedzera zvakanyanya njodzi yekenza yeganda. Saizvozvowo, inogona kukonzera matambudziko akakomba eziso senge maziso. Kune mhando dzakasiyana dzeganda uye mamwe ari panjodzi pane mamwe. Iko kunzwisisika kune ultraviolet radiation yeganda kunoenderana neinozivikanwa semufananidzo. Phototype iri mukutarisira kuyera kugona kweganda kunotora mwaranzi yezuva. Ndokunge, kugona kweganda kuburitsa melanin. Iyo violet index inofanirwa kunge ichizivikanwa chaizvo kuziva dziviriro yatinofanirwa kuisa kune iro ganda kune rezuva radiation maererano nekunzwa kwatinako. Vakatsvukuruka kana blonde vanhu vane hunyoro kupfuura brunettes.
Iyo inonzi ultraviolet index inobata kuyera kukwirisa kwemwaranzi yeultraviolet inosvika pamusoro penyika pane imwe neimwe yevelength inoremerwa nezviito zvayo zvinokuvadza pavanhu. Iyi indekisi yakaunzwa neEnvironment Canada masayendisiti muna 1992. Kubva ipapo, nyika dzinoverengeka dzakazivisa indices dzadzo kudzamara WHO yaunza indekisi yakajairwa yepasi rose.
UV Index Maitiro
Indekisi yeUV ine chirevo chepasi chinodzidziswa che 0 uye haina kukosha kwakanyanya. Iyo yakajairwa indekisi ndiyo iyo inotibvumidza isu kuti tiite fungidziro dzakasiyana siyana dzekufananidzwa kweUVI kutenderera pasirese. Iwo mavara ayo anoshandiswa kumiririra yekutanga vane yakasvibirira kune yakaderera UVI tsika pakati pe0 ne2, yero kune zvine mwero UVI tsika pakati pe3 ne5, orenji ine njodzi yakakwira pakati pe6 ne7. uye yakatsvuka kune akakwirira kwazvo eUVI maitiro ari pakati pe8 ne10 Pakupedzisira, futi Ruvara rwepepuru rwunowanikwa kune yakanyanya UVI tsika ine manhamba akakura kupfuura gumi nerimwe.
Zvichienderana nekukosha kweUVI uye zvinoenderana nerudzi rweganda rwemunhu wega wega, zera, nezvimwe. Matanho akakwana anofanirwa kutorwa kudzivirira kumwaranzi yeultraviolet. Iyo UVI inoenderana nezvinhu zvishoma uye inogona kuchinja mukati megore rose. Semuenzaniso, zvinoenderana nehuwandu hweozone mu iyo nzvimbo yemuchadenga, kukwirira kwezuva, kukwirira kwenzvimbo yatiri uye nerima iripo panguva iyoyo. Hazvina kufanana kuva pamwero wegungwa kupfuura pamusoro pegomo. Huwandu hwemwaranzi yezuva iri kuzokanganisa ganda redu unosiyana. Izvi zvakafanana nezve ozone layer. Iyo inotyisa ozone hole yaive nekuda kwekudzikiswa kweyakaunganidzwa ye stratospheric ozone uye ikozvino yakakwira chiitiko cheiyo ultraviolet mwaranzi yezuva pamusoro pedu.
Matanho ekuderedza mwaranzi inonzi ultraviolet
Tichapa mamwe ematanho akakosha kuti tikwanise kuzvidzivirira kubva pakuitwa nemwaranzi yeultraviolet paganda redu:
- Deredza kusvibiswa kwezuva panguva yakasimba yezuva. Aya ndiwo epakati maawa mune iyo huwandu hwesolar ultraviolet radiation iri mukurusa.
- Famba mumumvuri mumaawa epakati ezuva. Sezvo isu tichifanira kudzivisa kuzviisa pachena kuzuva repakati maawa, kana tisina imwe sarudzo tinofanirwa kuenda kumumvuri.
- Pfeka mbatya dzekudzivirira
- Pfeka ngowani yakafara-bharanzi kudzivirira maziso ako, kumeso, uye mutsipa.
- Dzivirira maziso edu nemagirazi ezuva
- Shandisa rakapamhama rezuva kudzivirira kirimu.
- Dzivisa kuwaridza mibhedha
Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezve iyo ultraviolet index uye kukosha kwayo.
