Kwigumbi lokuvavanya ukuguga kwe-ultraviolet, iisampuli zihlala zibekwe kwigumbi eliveziweyo elinezibane ze-ultraviolet ukulinganisa imitha ye-ultraviolet ekukhanyeni kwelanga.Igumbi lokuvavanya lihlala lixhotyiswe ngeenkqubo zokulawula ukushisa kunye nokufuma ukulinganisa imeko yangempela phantsi kweemeko ezahlukeneyo zokusingqongileyo.Ngaphantsi kwexesha elithile le-irradiation, utshintsho lombala, utshintsho lomsebenzi womzimba, utshintsho lwepropati yeekhemikhali, njl.Ke i-irradiance yegumbi lovavanyo lokuguga le-UV linokulawulwa ngeendlela ezahlukeneyo.Ezi zilandelayo ziindlela ezininzi zolawulo eziqhelekileyo:

1. Ukukhethwa komthombo wokukhanya: Iindidi ezahlukeneyo zemithombo yokukhanya zingasetyenziselwa ukulawula i-irradiance.Izibane ze-Ultraviolet ngomnye wemithombo yokukhanya esetyenziswa ngokuqhelekileyo enokukhipha ukukhanya kwe-ultraviolet.Ngokweemfuno zovavanyo, iintlobo ezahlukeneyo kunye namandla ezibane ze-ultraviolet zikhethwa ukulawula ukuqina kunye nobude be-irradiance.

2. Ukulungelelaniswa komgama: Ukulungelelanisa umgama phakathi kwesampuli yovavanyo kunye nesibane se-ultraviolet kunokuchaphazela ubuninzi be-irradiance.Okukhona ukufutshane umgama, kokukhona i-irradiance iphezulu;Okukhona umgama usiya usezantsi, kokukhona ukuncipha kweradiance.

3. Ulawulo lwexesha: Ubude bexesha lokukhutshwa kwemisebe bunokuba nefuthe kwi-irradiance.Okukhona ixesha lokufakwa kwemitha lide, kokukhona kunyuka iradiance;Okukhona lifutshane ixesha lokukhanya, kokukhona i-irradiance isezantsi.

4. Isihluzi sekhava: Ukusebenzisa iintlobo ezahlukeneyo zokucoca kunokukhetha ukuhluza ubude obungafunekiyo bemitha yemitha, ngaloo ndlela ilawula ukubunjwa kwe-irradiance.Ngokukhetha izihluzi ezifanelekileyo, ubungakanani bemitha yokukhanya kwamaza ahlukeneyo afana ne-UV-A, UV-B, kunye ne-UV-C inokulungiswa.

Ngokusebenzisa ngokubanzi ezi ndlela zingasentla, iradiance yegumbi lovavanyo lokuguga le-UV linokulawulwa ngokuguquguqukayo ngokweemfuno ezithile zovavanyo.
