Namuhla ake sikhulume ngokuthile nge-UV!Angazi ukuthi kungakanani okwaziyo ngemisebe ye-ultraviolet, nokuthi isahlala ezingeni elenziwa imisebe ye-ultraviolet eyenza isikhumba sibe mnyama.Eqinisweni, imisebe ye-ultraviolet inolwazi oluningi olufanele, oluyingozi kithi futhi oluzuzisayo.
Okokuqala, ake sazi imisebe ye-ultraviolet kuqala.Umbono wethu wansuku zonke wemisebe ye-ultraviolet uvela ekuvikelweni kwelanga nasekubulaweni amagciwane.Ngokuvamile, imikhiqizo yokuvikela ilanga izomakwa ngesiqubulo esithi "ukuvimbela imisebe ye-ultraviolet", futhi sivame ukusebenzisa imisebe ye-ultraviolet ukuze sibulale amagciwane.Ngakho-ke iyini imisebe ye-ultraviolet?
Incazelo esiyinikezwe yi-Wikipedia ukuthi imisebe ye-ultraviolet ikhona ngokwemvelo emvelweni, futhi iwuhlobo lokukhanya olungenakubonwa ngeso lenyama.Iwukukhanya okungabonakali okuphakeme kunokukhanya okuluhlaza okwesibhakabhaka-violet.
Okwesibili, ake sixoxe ngokuthi imisebe ye-UV isilimaza kanjani.Imisebe ye-Ultraviolet nayo iyingozi kakhulu kithi, ikakhulukazi amantombazane athanda ubuhle, abheka njengesitha semvelo.Njengokuguga kwesikhumba, ama-80% avela emisebeni ye-UV.Imisebe ye-Ultraviolet ingafinyelela ku-dermis yesikhumba, ibangele ukuthwebula kwesikhumba, ingene ijule esikhumbeni, ibe bomvu esikhumbeni, futhi ibangele umonakalo kuma-lipids ne-collagen, ibangele ukuthwebula kwesikhumba ngisho nomdlavuza wesikhumba.Ngakho-ke, imisebe ye-ultraviolet ayigcini nje ngokushukumisa umbala kodwa futhi yenza ithoni yesikhumba nemigqa emihle.
Nokho, ososayensi baye baguqula imisebe ye-UV isuka eyingozi yaba yinzuzo.Imisebe ye-Ultraviolet isetshenziswe isikhathi eside emakethe yokuvala inzalo nokubulala amagciwane.Izifundo zokuqala zaqala ngawo-1920, ngokusetshenziswa emakamelweni okusebenza ezibhedlela ngo-1936 nasezikoleni zokulawula ukudluliswa kwe-rubella ngo-1937. Izibani ze-Ultraviolet zingokonga, ziyasebenza, zilula, zilula futhi kulula ukuzisebenzisa.Manje ukubulawa kwamagciwane nge-ultraviolet kuyindlela evamile yokubulala amagciwane emoyeni, esetshenziswa kakhulu emagumbini okubonana nawo ezibhedlela, amagumbi okwelapha nasezindlini zokulahla amagciwane.
(Manje izikhungo ezahlukene zesevisi nezindawo zezentengiselwano zisebenzisa imikhiqizo yokubulala amagciwane e-ultraviolet ukuze kubulawe inzalo nokubulala amagciwane)
Ngemva kokuqonda le mizwa evamile, singakwazi ukuhlela imisebenzi yethu yangaphandle ngokuvumelana nesibikezelo se-ultraviolet esikhishwe isiteshi sesimo sezulu, futhi sizivikele kangcono emisebeni ye-ultraviolet.Ngesikhathi esifanayo, izibani ze-ultraviolet disinfection nazo zingenile ezindlini zethu.Okuvame kakhulu ukususa izibungu.Wonke umuntu uyazi ngezibungu.Ingase futhi isuse amagciwane asele ezifuyweni.Futhi singasebenzisa imikhiqizo ehlobene ye-UV ukuze usisize sihlanze umoya osizungezile futhi sizinikeze ikhwalithi yokuphila engcono.

Ngaphezu kwalezi ezijwayelekile, kukhona okungajwayelekile ukuthintwa yiwo wonke umuntu.Isibonelo, amaphrojekthi ethu kamasipala, njengezitshalo zokukhucululwa kwendle, iziteshi zikadoti, amanzi ezimboni (zasekhaya), njll., azosebenzisa amalambu e-ultraviolet.Eqinisweni, imikhiqizo ye-UV manje isibalulekile empilweni yami.
(Izimpilo zethu azihlukaniseki emikhiqizweni yokubulala amagciwane e-UV)
Okokugcina, kufanele kuqashelwe ukuthi ukusetshenziswa kwezibani ze-UV zokubulala amagciwane kudinga ukunakwa kokuphepha.Uma isetshenziswa ekhaya, abantu, izilwane ezifuywayo kanye nezitshalo kufanele zishiye indawo yokusebenza futhi azikwazi ukudalulwa isikhathi eside.Uma isibani se-UV sinomsebenzi we-ozone, sidinga ukungena ebangeni lokusebenza ihora elilodwa ngemva kokuvalwa komshini.I-ozone izodala umonakalo emzimbeni womuntu uma idlula ukuhlushwa okuthile, kodwa izobola ngokuzenzakalelayo futhi ingashiyi nsalela, ngakho ungakhathazeki.Ezinye izindawo kufanele zisetshenziswe ngochwepheshe ukuze kugwenywe izingozi.
Sekuyiminyaka engama-22 sigxile ekubulaweni kwe-ultraviolet nokubulala amagciwane.Uma unezidingo noma imibuzo, ungaxhumana nathi.
