Te hanganga ngota oNgā mimiti UVhe maha ngā hononga takirua honohono, ngā mowhiti kakara rānei kei roto, e taea ai te mimiti i ngā hihi ultraviolet o ngā roangaru motuhake (te nuinga o te UVA me te UVB).

Ina whiti ngā hihi ultraviolet ki ngā ngota mimiti, ka neke ngā irahiko i roto i ngā ngota mai i te āhua taketake ki te āhua whakahihiri, ka mimiti i te kaha o ngā hihi ultraviolet.

I muri i te mimiti i te mārama ultraviolet, ka noho te ngota i roto i te āhua whakaohooho me te kaha nui. Hei hoki ki te āhua whenua pumau, ka tukuna e ngā ngota mimiti te kaha i ngā huarahi e whai ake nei:
①Te whakawhiti kore-ira: te huri i te pūngao hei pūngao wera, ka tukuna ki te taiao e karapoti ana.
②Te hihi kanapa, te hihi whakapūangi rānei: ka tukuna pea tētahi wāhanga o te pūngao hei mārama e kitea ana (he onge noa iho).

Mā te mimiti i ngā hihi ultraviolet me te huri i aua hihi hei pūngao wera, ka whakaitihia e ngā mea mimiti UV te kino tika o ngā hihi ultraviolet ki ngā rauemi (pēnei i ngā kirihou, ngā paninga) me te kiri rānei.
I roto i ngā hua ārai rā, ka taea e ngā mea mimiti UV te aukati i te urunga o ngā hihi UV ki te kiri, me te whakaiti i te mōrearea o te werawera o te kiri, te koroheketanga o te kiri me te mate pukupuku kiri.

Tō mātouNgā mimiti UVhe pai mō ngā polymer, ngā paninga me ngā mea whakapaipai. Mena kei te hiahia koe ki ngā hua, tēnā whakapā mai, ka whakautu mātou i roto i ngā haora 48.
