UV lub teeb yog ib hom hluav taws xob hluav taws xob hluav taws xob uas muaj lub wavelengths luv dua li pom lub teeb tab sis ntev dua X-rays. UV spectrum tuaj yeem muab faib ua peb pawg: UV-A, UV-B, thiab UV-C. UV-A muaj qhov ntev tshaj plaws wavelengths thiab muaj nyob rau hauv tshav ntuj, whereas UV-B yog lub luag hauj lwm rau sunburns thiab daim tawv nqaij puas. UV-C muaj qhov luv tshaj wavelengths thiab yog hom teeb meem tshaj plaws ntawm UV hluav taws xob, vim nws tau nqus los ntawm DNA thiab ua rau muaj kev puas tsuaj rau cov hlwb nyob.
Qhov sib txawv loj tshaj ntawm UV teeb thiab UV-C lub teeb yog lub wavelength. Raws li tau hais, UV-C muaj qhov luv luv luv dua li UV-A lossis UV-B, ua rau nws muaj txiaj ntsig zoo hauv kev rhuav tshem molecular bonds. Thaum UV-A thiab UV-B tau siv ntau yam kev siv xws li kho cov nplaum los yog lub txaj tanning, UV-C yog siv rau kev tua kab mob thiab ua kom tsis muaj menyuam.
UV-C teeb feem ntau yog siv los tua kab mob thiab kab mob. Nws ua haujlwm los ntawm kev cuam tshuam DNA ntawm cov kab mob, kab mob, thiab lwm yam kab mob, tiv thaiv lawv los ntawm kev tsim tawm thiab tua lawv thaum kawg. Vim li no, UV-C lub teeb tau siv nyob rau hauv ntau yam kev lag luam nrog rau kev kho mob, khoom noj khoom haus thiab dej haus, thiab kev kho dej los pab tswj qhov chaw tsis muaj menyuam.
Txhawm rau tsim UV-C lub teeb, yuav tsum muaj lub teeb tshwj xeeb. Cov qij no muaj mercury vapor thiab phosphor txheej uas emits UV-C hluav taws xob thaum lub mercury vapor zoo siab los ntawm cov hluav taws xob tam sim no. UV-C qhov muag teev tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab cov duab thiab muaj qhov sib txawv wattage, nyob ntawm daim ntawv thov. Lawv tuaj yeem siv rau hauv cov tshuab ua kom huv hauv huab cua, cov chaw kho dej, thiab txawm tias cov khoom siv tes tuav kom tsis muaj menyuam.
Hauv kev xaus, qhov sib txawv tseem ceeb ntawm UV teeb thiab UV-C lub teeb yog lub wavelength. UV-C muaj luv wavelengths thiab feem ntau yog siv los tua kab mob thiab ua kom tsis muaj menyuam. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov ntev ntawm cov hluav taws xob UV-C tuaj yeem ua rau muaj kev phom sij rau cov kab mob muaj sia, yog li kev ntsuas kev nyab xeeb yuav tsum tau ua thaum tuav UV-C teeb lossis cov khoom siv.
