(1) Qhov kev siv hluav taws xob ntawm lub teeb nrig ultraviolet maj mam txo qis nrog lub sijhawm dhau los, yog li qhov siv hluav taws xob ntawm ultraviolet lub teeb yuav tsum ntsuas kom tsis tu ncua, thiab thaum nws poob qis dua qhov yuav tsum tau ua, nws yuav tsum tau hloov lub sijhawm.
(2) Lub neej ua haujlwm ntawm ultraviolet kab mob teeb pom kev zoo, uas yog, lub sijhawm txo cov kev siv zog ntawm lub teeb tshiab rau 70μW / cm2(lub zog ≥30w), lossis lub sijhawm los txo kom 70% ntawm kev siv lub teeb tshiab (fais fab< 30w),="" yuav="" tsum="" tsis="" pub="" tsawg="" dua="">
(3) Lub teeb tiv thaiv ultraviolet yog lub teeb ua haujlwm siv lub teeb tiv thaiv ultraviolet tiv thaiv kab mob: qhov siv xav tau hluav taws xob 253.7nm ultraviolet lub teeb (ntsuas ntawm lub teeb ze ntawm 1m los ntawm nruab nrab ntawm lub raj) yog: lub hwj chim 30w teeb,> 170μW / cm2; 11W teeb,> 40μW / cm2.
