Amateka yo kuvura urumuri

Ubuvuzi bworoheje bwabayeho igihe cyose ibimera ninyamaswa byabaye ku isi, kuko twese twungukirwa kurwego runaka nizuba risanzwe.

Ntabwo urumuri rwa UVB ruturuka ku zuba rukorana na cholesterol mu ruhu kugira ngo rufashe gukora vitamine D3 (bityo bikagira inyungu umubiri wose), ariko igice gitukura cyumucyo ugaragara (600 - 1000nm) nacyo gikorana na enzyme yingenzi ya metabolike muri mitochondria ya selile yacu, kuzamura umupfundikizo kubushobozi bwacu butanga ingufu.

Ubuvuzi bwumucyo bwa none bwabayeho kuva mu mpera za 1800, bidatinze nyuma y’amashanyarazi n’umuriro wo mu rugo bibaye ikintu, igihe ikirwa cya Faroe cyavutse Niels Ryberg Finsen yagerageje n’umucyo nk'umuti w’indwara.

Nyuma Finsen yaje gutsindira igihembo cyitiriwe Nobel cy’ubuvuzi mu 1903, umwaka 1 mbere y’urupfu rwe, atsindira cyane kuvura ibicurane, ibibyimba ndetse n’izindi ndwara z’uruhu akoresheje urumuri rwinshi.

Ubuvuzi bwambere bwumucyo bwarimo cyane cyane gukoresha itara gakondo, kandi 10,000s yubushakashatsi bwakozwe kumucyo mu kinyejana cya 20.Ubushakashatsi buva ku ngaruka zangiza inyo, cyangwa inyoni, abagore batwite, amafarasi nudukoko, bagiteri, ibimera nibindi byinshi.Iterambere riheruka kwari ukumenyekanisha ibikoresho bya LED na laseri.

Nkuko amabara menshi yabonetse nka LED, kandi imikorere yikoranabuhanga itangira gutera imbere, LED yabaye amahitamo yumvikana kandi meza yo kuvura urumuri, kandi ni amahame yinganda muri iki gihe, hamwe nibikorwa bikomeza gutera imbere.
