Ishusho yibendera: Itara rya ultraviolet riva kumatara ya krypton ya chloride ikoreshwa na molekile zigenda hagati yingufu zitandukanye.(Inkomoko: Itsinda ry'ubushakashatsi bwa Linden)
Ubushakashatsi bushya bwakozwe na kaminuza ya Colorado Boulder bwerekanye ko uburebure bw’umurabyo wa ultraviolet (UV) butagira akamaro kanini mu kwica virusi itera COVID-19, ariko kandi ni byiza kuyikoresha ahantu rusange.
Ubu bushakashatsi bwasohotse muri uku kwezi mu kinyamakuru cyitwa Applied and Environmental Microbiology, ni isesengura rya mbere ryuzuye ry’ingaruka z’uburebure butandukanye bw’umucyo ultraviolet kuri SARS-CoV-2 n’izindi virusi z’ubuhumekero, harimo imwe yonyine itekanye ku binyabuzima kandi ntibisaba guhuza umurongo.Rinda.
Abanditsi bavuze ko ibyavuye mu bushakashatsi “bahindura umukino” kugira ngo bakoreshe urumuri rwa UV rushobora kuganisha kuri sisitemu nshya zihendutse, zifite umutekano kandi zifatika zo kugabanya ikwirakwizwa rya virusi ahantu hahurira abantu benshi nko ku bibuga by’indege ndetse n’ibitaramo.
Umwanditsi mukuru Carl Linden, umwarimu w’ubuhanga bw’ibidukikije yagize ati: "Muri virusi hafi ya zose twize, iyi virusi ni imwe mu zoroshye kwica hakoreshejwe urumuri ultraviolet".“Bisaba dosiye nkeya.Ibi byerekana ko ikoranabuhanga rya UV rishobora kuba igisubizo cyiza cyo kurinda ahantu rusange. ”
Imirasire ya ultraviolet isanzwe isohoka nizuba, kandi uburyo bwinshi bwangiza ibinyabuzima kimwe na mikorobe nka virusi.Uyu mucyo urashobora kwinjizwa na genome y'ibinyabuzima, ugahambira ipfundo kandi ukirinda kubyara.Nyamara, ubwo burebure bwangiza buturuka ku zuba bwungururwa na ozone mbere yuko bugera ku isi.
Ibicuruzwa bimwe bisanzwe, nk'amatara ya fluorescent, akoresha imirasire ya UV ya ergonomique, ariko afite imbere imbere ya fosifore yera ibarinda imirasire ya UV.
Linden yagize ati: "Iyo dukuyeho igifuniko, dushobora gusohora uburebure bw’umuraba bushobora kwangiza uruhu rwacu n'amaso, ariko birashobora no kwica virusi."
Ibitaro bimaze gukoresha tekinoroji ya UV kugirango yanduze ubuso ahantu hadatuwe kandi ikoresha robot kugirango ikoreshe urumuri UV hagati yibyumba byo gukoreramo n’ibyumba by’abarwayi.
Ibikoresho byinshi kumasoko uyumunsi birashobora gukoresha urumuri rwa UV kugirango usukure ibintu byose uhereye kuri terefone ngendanwa kugeza kumacupa yamazi.Ariko FDA na EPA baracyategura protocole yumutekano.Linden arihanangiriza kwirinda gukoresha ibikoresho ibyo ari byo byose cyangwa “sterilisation” bigaragariza abantu urumuri ultraviolet.
Yavuze ko ubushakashatsi bushya budasanzwe kuko bugereranya hagati y’urumuri ultraviolet, rufite umutekano muke ku bantu kandi rwangiza virusi, cyane cyane virusi itera COVID-19.
Muri ubu bushakashatsi, Linden hamwe nitsinda rye bagereranije uburebure butandukanye bwurumuri rwa UV bakoresheje uburyo busanzwe bwatejwe imbere muruganda rwa UV.
Linden yagize ati: "Turatekereza ko reka duhuze maze dusobanure neza umubare wa UV ukenewe mu kwica SARS-CoV-2".“Turashaka kumenya neza ko niba ukoresheje urumuri rwa UV mu kurwanya indwara, uzatsinda”.Igipimo cyo kurinda ubuzima bwa muntu n’uruhu rwabantu no kwica izo virusi. ”
Amahirwe yo gukora imirimo nkiyi ni gake kuko gukorana na SARS-CoV-2 bisaba amahame akomeye yumutekano.Linden na Ben Ma rero, mugenzi w’iposita mu itsinda rya Linden, bafatanije n’umuhanga mu bya virusi witwa Charles Gerba wo muri kaminuza ya Arizona muri laboratoire yemerewe kwiga virusi n’ibindi bitandukanye.
Abashakashatsi basanze ko nubwo muri rusange virusi zumva cyane urumuri rwa ultraviolet, uburebure bwa kure-ultraviolet (222 nanometero) bugira akamaro cyane.Uburebure bwumurongo bwakozwe namatara ya krypton chloride excimer, akoreshwa na molekile zigenda hagati yingufu zitandukanye kandi ni ingufu nyinshi cyane.Nkibyo, irashobora kwangiza byinshi kuri poroteyine za virusi na acide nucleic kurusha ibindi bikoresho bya UV-C kandi igahagarikwa n’inyuma y’uruhu n’amaso y’umuntu, bivuze ko nta ngaruka mbi byangiza ubuzima.yica virusi.
Imirasire ya UV ifite uburebure butandukanye (bupimwe hano muri nanometero) irashobora kwinjira mubice bitandukanye byuruhu.Iyo uburebure bwimbitse bwinjira mu ruhu, niko byangiza byinshi..
Kuva mu ntangiriro z'ikinyejana cya 20, uburyo butandukanye bw'imirasire ya UV bwakoreshejwe cyane mu kwanduza amazi, umwuka, ndetse n'ubuso.Nko mu myaka ya za 1940, yakoreshejwe mu kugabanya ikwirakwizwa ry'igituntu mu bitaro no mu byumba by'amashuri mu gucana igisenge kugira ngo yanduze umwuka uzenguruka mu cyumba.Uyu munsi ntabwo ikoreshwa mu bitaro gusa, ahubwo no mu bwiherero rusange ndetse no mu ndege iyo ntawe uri hafi.
Mu mpapuro zera ziherutse gutangazwa n’umuryango mpuzamahanga Ultraviolet, Imirasire ya Far-UV: Ubumenyi bugezweho (hamwe n’ubushakashatsi bushya), Linden hamwe n’abandi banditsi bavuga ko ubu burebure bw’umuraba-UV bushobora gukoreshwa hamwe no guhumeka neza, kwambara masike hamwe ninkingo ningamba zingenzi zo kugabanya ingaruka zibyorezo byubu nibizaza.
Linden Iyumvire sisitemu irashobora gukingurwa no kuzimya ahantu hafunze kugirango isukure ikirere hamwe nubuso buri gihe, cyangwa bigatera inzitizi zihoraho zitagaragara hagati yabarimu nabanyeshuri, abashyitsi n'abakozi bashinzwe kubungabunga, hamwe nabantu ahantu hataboneka intera mbonezamubano.
Kwanduza UV birashobora no guhangana n'ingaruka nziza ziterwa no guhumeka neza mu nzu, kuko bishobora gutanga uburinzi bumwe no kongera umubare w’imihindagurikire y’ikirere ku isaha mu cyumba.Gushyira amatara ya UV nabyo bihenze cyane kuruta kuzamura sisitemu yawe yose ya HVAC.
Ati: “Hano hari amahirwe yo kuzigama amafaranga n'ingufu mu gihe turinda ubuzima rusange.Birashimishije rwose. ”
