Na Leseli la UVC le ka Koala Coronavirus?

Bareki ba kanna ba batla ho reka mabone a Ultra-violet (UVC) ho hloekisa bokaholimo ba ntlo kapa libakeng tse ling tse tšoanang ho latela seoa sa hajoale sa lefu la Coronavirus Sickness 2019 (COVID-19) le hlahisitsoeng ke coronavirus e ncha SARS-CoV-2 

Leseli la UV ke Eng?

Leseli la UV (ultraviolet) ke mofuta o mong oa mahlaseli a motlakase. E na le bolelele bo bokhutšoane ho feta khanya e bonahalang, kahoo ha e bonahale ka mahlo, empa e ka bonoa ka phello ea eona linthong tse fapaneng. Mahlaseli a UV a ka fetola maqhama a lik'hemik'hale ka har'a limolek'hule, a baka liphetoho tsa lik'hemik'hale, hape a ka etsa hore lintho tse ngata li khanye kapa li hlahise khanya. Mahlaseli a UV a theola sebopeho sa ketane ea lipolymer, e leng se bakang tahlehelo ea matla, mohlomong le ho fifala le ho phatloha. E boetse e monngoa ke li-pigment tse ngata le dae, e leng se etsang hore li fetole 'mala. Leseli la UV  li etsahala ka tlhaho khanyeng ea letsatsi hape li ka hlahisoa ke mehloli ea khanya ea maiketsetso.

Mefuta ea Leseli la UV ?

• UVA, kapa haufi le UV (315–400 nm), leseli la UVA le na le matla a tlase haholo. Ha u le letsatsing, u pepesetsoa khanya ea UVA. Ho pepesetsoa khanya ea UVA ho amahanngoa le botsofali ba letlalo le tšenyo.
• UVB, kapa UV e bohareng (280–315 nm), lebone la UVB le bohareng ba mahlaseli a mahlaseli a kotsi. Karolo e nyenyane ea khanya ea letsatsi e na le khanya ea UVB. Ke mofuta o ka sehloohong oa mahlaseli a UV a bakang ho chesoa ke letsatsi le mefuta e mengata ea kankere ea letlalo.
• UVC, kapa UV e hole (180–280 nm), leseli la UVC le na le matla a mangata. Boholo ba khanya ea UVC e tsoang letsatsing e monngoa ke ozone ea Lefatše, ka hona, hangata ha u e bone letsatsi le leng le le leng. Leha ho le joalo, ho na le mefuta e fapaneng ea mehloli ea maiketsetso ea UVC.

Bophahamo ba maqhubu a lebone bo ka ama tsela eo le ka thibelang livaerase hantle le ts'ireletso le mathata a bophelo a ka amehang. Ho lekola lebone ho ka senola hore na le ntša mahlaseli a mangata hakae le hore na le hlahisa bokae ba maqhubu a mang a eketsehileng. Kaha li-LED ha li na mercury, li na le molemo ho feta mabone a mercury a khatello e tlase 

Hona joale, liteko li paka hore leseli la UVC ke mofuta o sebetsang ka ho fetisisa oa lebone la ultraviolet ho bolaea libaktheria. E ka sebelisoa ho thibela likokoana-hloko bokaholimo, moea le maro. Leseli la UVC le bolaea likokoana-hloko tse kang livaerase le libaktheria ka ho senya limolek'hule tse kang nucleic acid le liprotheine. Sena se etsa hore ho se khonehe hore libaktheria li phethe mekhoa eo li e hlokang hore li phele.

Mabapi le Leseli la UVC le Novel Coronavirus

Coronavirus e ncha e ile ea lekoa litsong tsa metsi tse sebelisang leseli la UVC boithutong ba morao-rao bo phatlalalitsoeng ho Makasine ea Amerika ea Taolo ea Ts'oaetso.

Leseli la UVC bakeng sa ho bolaea likokoana-hloko

  Phuputso ea morao-rao ho American Journal of Infection Control (AJIC) e ile ea etsa lipatlisiso ka tšebeliso ea lebone la UVC ho bolaea palo e kholo ea li-coronaviruse tse ncha litsong tsa metsi. Boithuto bona bo fumane hore metsotso e 9 ea mahlaseli a khanya a UVC a ka etsa hore kokoana-hloko e sebetse ka botlalo.

Mokhoa oa ho sebelisa mabone a UVC ho bolaea Coronavirus

Ho thata ho hloekisa metsi, moea, le libaka le libaka tse itseng. Mabone a UVC a ka sebelisoa ho bolaea likokoana-hloko tikolohong ena. Ka mohlala,  Mabone a UVC 'me liroboto li sebelisetsoa ho bolaea metsi ka metsi, bokaholimo ba likamore tsa sepetlele tse se nang letho, le likoloi tse kholo joalo ka libese  Mabone a UVC  e ka sebelisoa libakeng tse bulehileng ka tlung ho thibela likokoana-hloko tse tsamaisoang ke moea le likokoana-hloko tse ling.
