Ngā mea whakamārama whatu, e mōhiotia ana kongā whakakanapa whatu(OBA), he matū e whakamahia ana hei whakapai ake i te āhua o ngā rauemi mā te whakanui ake i tō rātou mā me te kanapa. He mea whakamahi noa ēnei i roto i ngā momo ahumahi, tae atu ki ngā kakahu, pepa, hopi horoi me ngā kirihou. I roto i tēnei tuhinga, ka tūhuratia e mātou he aha ngā mea whakakanapa whatu, me pēhea te mahi, me ā rātou whakamahinga rerekē.

Ko te mahi a ngā whakakanapa whatu mā te mimiti i te mārama ultraviolet (UV) ka tukuna anō hei mārama kitea i roto i te whānuitanga kikorangi-papura. Ka kiia tēnei āhuatanga ko te fluorescence. Mā te huri i ngā hihi UV hei mārama kitea, ka whakarei ake ngā whakakanapa whatu i te whakaata me ngā āhuatanga fluorescence o ngā rauemi, ka ātaahua ake, ka mā ake te āhua.

Ko tētahi whakamahinga noa o ngā whakakanapa whatu kei roto i te umanga kakahu. I roto i ngā kakahu, ka tāpirihia ngā whakakanapa whatu ki ngā papanga me ngā muka hei whakapai ake i te āhua o te tirohanga. Ina tukuna ngā kākahu, ngā papanga rānei kua whakaranua ki ngā whakakanapa whatu ki te rā, ki te mārama horihori rānei, ka mimitihia e rātou ngā hihi UV e puta ana, ka tukuna te mārama e kitea ana, ka mā ake, ka kanapa ake te āhua o te kakahu. He tino hiahiatia tēnei pānga ki ngā papanga mā, ki ngā papanga mārama rānei, hei whakarei ake i te ma me te hou.

Ko tētahi atu ahumahi e whakamahi nui ana i ngā whakakanapa whatu ko te ahumahi pepa. Ka tāpirihia ngā whakakanapa whatu i te wā o te tukanga hanga pepa hei whakanui ake i tōna kanapa, kia mā ake ai te āhua. Mā te whakanui ake i te mā o te pepa,ngā whakakanapa whatuāwhina ki te whakaputa i ngā tānga me ngā whakaahua kounga teitei. Ka āwhina hoki rātou ki te whakaiti i te nui o te mangumangu e hiahiatia ana mō te tānga, ka hua ake he penapena utu mō ngā kamupene tā me ngā kaihoko.

He mea noa hoki ngā whakakanapa whatu i roto i ngā hopi horoi kakahu. Ka tāpirihia ēnei ki ngā tauira hopi horoi kia mā ake ai te āhua o ngā kākahu mā, kia kanapa ake ai hoki ngā tae. Ina horoia ngā kākahu ki ngā hopi horoi kei roto ngā whakakanapa whatu, ka whakatakotoria ēnei matū ki te mata o te papanga, ka mimiti i ngā hihi ultraviolet ka tukuna te mārama kikorangi, ka huna i te tae kōwhai me te whakarei ake i te kanapa whānui o ngā kākahu. Mā tēnei ka noho ma ake, ka hou ake te āhua o ngā kākahu, ahakoa he maha ngā horoinga.

Hei tāpiritanga,ngā whakakanapa whatue whakamahia ana hoki i roto i te hanga kirihou. Ka tāpirihia ēnei ki te kirihou i te wā o te tukanga whakaputa hei whakapai ake i tōna āhua, hei whakanikoniko hoki. Ko ngā hua kirihou pēnei i ngā pounamu, ngā ipu me ngā rauemi tākai kua whakamaua ki ngā whakakanapa whatu ka kitea he kanapa ake, he ātaahua ake hoki i runga i ngā whata toa. Mā te whakamahi i ngā whakakanapa whatu i roto i ngā kirihou ka āwhina hoki ki te huna i ngā hapa, i te kōwhai rānei ka puta i roto i te wā nā te pānga o te rā, ngā āhuatanga taiao rānei.

Hei whakarāpopototanga, ko ngā whakakanapa whatu he matū e whakamahia whānuitia ana i roto i ngā momo ahumahi hei whakapai ake i te mā me te kanapa o ngā rauemi. Mā te mimiti i te mārama ultraviolet me te tuku anō hei mārama kitea, ka āwhina ngā whakakanapa whatu ki te whakapai ake i te āhua tirohanga o ngā kakahu, pepa, hopi horoi me ngā kirihou. He mea nui ēnei hei whakatutuki i ngā āhuatanga ataahua me te tirohanga e hiahiatia ana mō ēnei rauemi. Ahakoa te whakapai ake i te āhua o ngā kakahu, te koi ake o ngā tānga pepa, te ātaahua ake rānei o ngā kirihou, he mea nui te whakakanapa whatu ki te whakarei ake i te wheako tirohanga whānui.
