Kev Siv Tshuab Txheej Iav rau Kev Tiv Thaiv UV
Iav yog ib yam khoom siv uas siv ntau zaus hauv ntau yam ntawm lub neej niaj hnub no, txij li kev tsim kho vaj tse mus rau kev siv tsheb thiab txawm tias cov khoom siv hluav taws xob. Tsis tas li ntawd xwb, iav kuj tseem tuaj yeem tsim los tiv thaiv los ntawm cov teeb ci ultraviolet (UV), uas paub tias ua rau tib neeg noj qab haus huv thiab cov khoom siv ib puag ncig puas tsuaj. Ib qho thev naus laus zis uas tam sim no siv dav los txhim kho qhov kev tiv thaiv no yog thev naus laus zis txheej iav rau kev tiv thaiv UV.
Cov teeb UV yog dab tsi?
Lub teeb ultraviolet (UV) yog ib feem ntawm lub teeb hluav taws xob electromagnetic spectrum uas tib neeg lub qhov muag tsis pom. Nws muab faib ua peb pawg raws li nws qhov wavelength: UV-A, UV-B, thiab UV-C. UV-A (315-400 nm) yog qhov tsis zoo tshaj plaws tab sis tseem ua rau daim tawv nqaij laus. UV-B (280-315 nm) yog lub luag haujlwm rau kev kub hnyiab thiab yog qhov tseem ceeb ua rau mob qog nqaij hlav. UV-C (100-280 nm) yog qhov txaus ntshai tshaj plaws, tab sis feem ntau raug nqus los ntawm huab cua ntawm lub ntiaj teb.
Qhov Cuam Tshuam ntawm UV Rays rau Lub Neej
Kev raug tshav ntuj UV ntau dhau tsis yog tsuas yog cuam tshuam rau tib neeg txoj kev noj qab haus huv xwb tab sis kuj cuam tshuam rau ntau yam khoom siv. Cov no suav nrog:
- Kev Noj Qab Haus Huv ntawm Tawv Nqaij: Kev raug UV tuaj yeem ua rau laus ua ntej lub sijhawm, kub hnyiab, thiab ua rau muaj kev pheej hmoo ntawm mob qog nqaij hlav ntawm daim tawv nqaij.
– Qhov Muag: Kev raug UV tuaj yeem ua rau lub cornea thiab lens ntawm lub qhov muag puas tsuaj, thiab ua rau muaj kev pheej hmoo ntawm cataracts.
– Cov Khoom Siv: UV tuaj yeem ua rau cov khoom siv organic lwj, ua rau muaj kev hloov pauv xim, tawg, lossis txawm tias kev puas tsuaj rau cov qauv ntawm qee yam khoom siv, xws li yas thiab xim.
Yog li ntawd, kev tiv thaiv tiv thaiv UV hluav taws xob tseem ceeb heev.
Kev Siv Tshuab Txheej Txheem rau Kev Tiv Thaiv UV
Ib txheej txheej yog ib txheej nyias nyias uas siv rau saum npoo ntawm lub iav kom ua haujlwm tau zoo dua. Hauv qhov no, txheej txheej UV yog ib txheej uas siv los txo qhov kev kis ntawm lub teeb ultraviolet los ntawm lub iav. Muaj ntau hom txheej txheem txheej txheej siv rau lub hom phiaj no.
