Byose ukeneye kumenya ku bijyanye no guhitamo umutaka urinda imirasire y'izuba neza
Umutaka w'izuba ni ngombwa mu mpeshyi yacu, cyane cyane ku bantu batinya gukaraba, ni ngombwa cyane guhitamo umutaka w'izuba mwiza. Ariko, umutaka ushobora gukorwa mu myenda itandukanye, ahubwo uza mu mabara atandukanye kandi ufite ingaruka zitandukanye cyane zo kurinda izuba. None se ni uwuhe mutaka w'ibara ryiza? Nigute wahitamo umutaka w'izuba mwiza? Hanyuma, ndaguha isesengura rya siyansi ry'umutaka w'izuba ufite ibara ry'izuba, kandi dusangire inama z'uburyo wagura umutaka wuzuye izuba, reba.
Dukurikije ibyavuye mu isuzuma ryakozwe n’Ishuri Rikuru ry’Ubushinwa ry’Ubumenyi bw’Ibipimo, ibara ry’umwenda naryo rigira uruhare mu gukumira izuba rya UV. Uko wijimye cyane, niko umuvuduko wo kwanduza UV uba muto kandi niko imikorere yo kurinda UV iba myiza. Mu bihe bimwe, uko ibara ry’umwenda ryijimye cyane, niko imikorere yo kurwanya UV iba myiza kurushaho. Ugereranije, umukara ni wo utuma ugaragara neza.
Ugereranije, umukara, umukara w’umweru, icyatsi cyijimye kurusha ubururu bwerurutse, umutuku werurutse, umuhondo werurutse, nibindi. Ingaruka za UV zo mu gace ni nziza.
Umutaka w'izuba uburyo bwo guhitamo uburyo bwo kurinda izuba cyane
Amasambu manini ashobora kuziba hafi 70% by'imirasire ya ultraviolet, ariko ntashobora gutandukanya imiterere yagaragaraga hanze y'umurongo.
Imitaka isanzwe ishobora kandi kuzibira imirasire myinshi ya UV, nk'uko byavuzwe haruguru, uko umutaka wijimye cyane niko ibara ry'umutaka ryijimye rirushaho kuba ryiza. Ariko, niba uhisemo izuba rinini rifite irangi ririnda UV, ugomba gusuzuma ibintu bitandukanye, nko igiciro, urwego rw'uburinzi. Imyenda ya Umbrella n'ibindi, kugira ngo ubashe kugura umutaka wizewe.
Reba igiciro
Amwe mu masenge ashobora gutwikira imirasire y'izuba gusa, kandi imirasire ya ultraviolet izakomeza kwinjira mu mwenda, nyuma yo kuvurwa n'isuku y'izuba kugira ingaruka zo kurwanya imirasire ya ultraviolet. Rero ntabwo ari amasenge azashobora kurinda imirasire ya ultraviolet. Umusenge wujuje ibisabwa, urinda imirasire ya ultraviolet, igiciro cyayo ni nibura yuan 20. Rero koresha amadolari make kugura umusenge, ubushobozi bwo kurinda imirasire ya ultraviolet burakemangwa.
Reba urwego rw'uburinzi
Iyo agaciro k’uburinzi bwa UV karenze 30, ni ukuvuga UPF30+, kandi igipimo cyo kwanduza UV mu buryo bw’umurambararo kiri munsi ya 5%, gishobora kwitwa ibikoresho byo kurinda UV; kandi iyo UPF>50, bigaragaza ko ibicuruzwa bifite uburinzi bwiza bwa UV, ikimenyetso cy’urwego rwo kurinda UPF50+. Uko agaciro ka UPF kaba kanini, niko imikorere myiza yo kurinda UV.
