Ultraviolet lub teebyog hais txog lub teeb pom tsis pom nrog lub wavelength ntau ntawm 100-400 nm. Qhov sib txawv wavelength ntawm ultraviolet lub teeb muaj cov haujlwm sib txawv.
Lub teeb ultraviolet tau muab faib ua plaub ntu raws li wavelength:
A-band, hu ua black spot effect ultraviolet (400-320nm), tau txuas cov xim thiab cov nyhuv photochemical, tseem hu ua tshuaj kab;
B-band, hu ua erythema effect ultraviolet (320-275nm), tuaj yeem txhawb kev tsim cov vitamin D, uas yog hu ua kab noj qab haus huv;
C-band, hu ua sterilization ultraviolet (275-200nm), muaj kev ua kom tsis muaj menyuam;
D-band, hu ua lub tshuab nqus tsev ultraviolet (200-100nm), tuaj yeem tsim cov ozone zoo.
Cov tshuaj tua kab mob ultraviolet yog ib txoj kev tua kab mob hauv lub cev, uas tsis tua cov kab mob (cov kab mob, kab mob, cov kab mob thiab lwm yam kab mob), tab sis ua rau lawv poob lawv lub peev xwm xeeb tub thiab inactivate lawv.
Lub hauv paus ntsiab lus ntawm kev siv tshuaj tua kab mob ultraviolet feem ntau suav hais tias yog siv ultraviolet C-band (UV-C) los hloov thiab rhuav tshem cov khoom siv noob caj noob ces nucleic acid (DNA lossis RNA) ntawm cov kab mob, kom cov kab mob poob lub peev xwm ntawm cov protein synthesis, replication thiab reproduction.
Ultraviolet tshuaj tua kab mob feem ntau siv C-band, raws li qhia hauv daim duab hauv qab no. Qhov nqus spectrum ntawm DNA yog 240-280nm, thiab qhov siab tshaj plaws nqus yog li 260nm.
