I roto i te whakahaere wai ahumahi, kāore e taea te whiriwhiri i te tika me te whai huatanga—engari he rite tonu te whakahaere utu mō te wā roa. Mō ngā mahi mai i ngā tipu maimoatanga wai ki ngā whare hanga matū, ko te rapu taputapu ine e whakataurite ana i te tika me te iti o te tiaki kua arahina te tini ki tētahi otinga whakarerekē kēmu: ngā mita rere hikohiko (EMF) iti-te tiaki. He rerekē ki ngā mita rere mīhini tuku iho e whakawhirinaki ana ki ngā wāhanga neke e ngāwari ana ki te kakahu, te aukati, te waikura rānei, ka whakamahia e ēnei taputapu matatau te Ture a Faraday mō te whakapūtanga hikohiko hei tuku raraunga pono—me te whakaiti i te wā tiaki, ngā utu mahi, me te wā kore mahi i whakaritea. I roto i te whenua ahumahi tere o ēnei rā, ehara i te mea he mea whai hua noa ngā EMF iti-te tiaki; he haumi rautaki ki te hiranga o te mahi.
Kei te pūtake o te uara o ngā EMF iti-tiaki ko tō rātou hoahoa kore-whakauru, kore-wāhanga. Ko ngā mita rere tuku iho, pērā i ngā tauira tāpine, ngā tauira nekehanga pai rānei, ka whakamahi i ngā wāhanga hurihuri, i ngā arai tinana rānei hei ine i te rere o te wai. I roto i te wā, ka pakaru ēnei wāhanga nā te waku, te pānga ki ngā wai whakakoi, waikura rānei (hei tauira, te wai para me ngā paru, te paru matū), te kohikohinga rānei o ngā poke pērā i te unahi, te paru rānei. Nā tēnei pakaru ka akiakihia ngā tirotiro auau, ngā whakakapinga wāhanga, me te whakatikatika—he tukanga utu nui e hiahia ana kia kati te pūnaha katoa. Ko ngā EMF iti-tiaki, he rerekē, kāore he wāhanga neke. Engari, kei roto he ngongo pūoko kua whakakikoruatia ki ngā rauemi ātete-waikura (hei tauira, PTFE, rapa) me ngā koiri hikohiko e rua. Ina haere te wai i roto i te ngongo, ka whakaputahia e ngā koiri he papa aukume, ā, ka kitea e ngā irahiko te ngaohiko i puta mai i te nekehanga o te wai—e tatau tika ana i te tere rere me te kore he pa tinana. Mā tēnei hoahoa ka whakakorea te mōrearea o te rahunga wāhanga, te aukati, te kakahu miihini rānei, ka whakaiti nui i te hiahia mō te ratonga auau. Hei tauira, mō te tipu maimoatanga wai ā-tāone, ko te tikanga o tēnei ko te karo i te kati ā-marama ki te horoi i ngā mita tāpine; engari, ka mahi tonu te EMF, me ngā tirotiro whakatikatika ā-tau anake e hiahiatia ana.
Haunga te whakaiti i te mahi tiaki, ka whakapiki ake ngā EMF iti-tiaki i te whai huatanga o te utu mā te roa me te maha o ngā mahi. Ko tō rātou hanganga pakari—tae atu ki ngā whare kowiri tira me ngā arai ātete-matū—ka whakarite kia tu atu rātou i ngā taiao ahumahi uaua, mai i ngā whare hinu pāmahana teitei ki ngā mahi keri waikawa. Kāore i rite ki ngā mita mīhini e hiahia ana kia whakakapia katoatia i ia 2–3 tau, ka taea e te EMF pai te roa mō te tekau tau neke atu rānei, ka tapahia ngā huringa whakapaunga whakapaipai. Hei tāpiri, ko tō rātou kaha ki te ine i te whānuitanga o ngā wai—mai i ngā wai kawe (wai, matū) ki ngā paru matotoru (sima, whakapiri kai)—ka whakakore i te hiahia ki te haumi ki ngā momo mita maha mō ngā tukanga rerekē. Hei tauira, ka taea e te kaihanga kai me te inu te whakamahi i te EMF iti-tiaki kotahi hei aroturuki i te rere o te tirikara i roto i te raina pounamu me te tukunga waipara, ka karo i te utu o ngā mita motuhake mō ia tono. Ko tēnei maha-tikanga ehara i te mea ka whakangawari noa i te whakahaere taonga engari ka whakaitihia hoki te wā whakangungu mō ngā kaimahi, me ako noa i te mahi a te taputapu kotahi.
He mea nui, kāore ngā EMF iti-tiaki e whakararu i te tika o te ine mō te watea—he āwangawanga matua mō ngā ahumahi e pā tika ana ngā raraunga rere tika ki te kounga o te hua, te tutuki i ngā ture, me te arotau rauemi. Ka tukuna e tā rātou hangarau hikohiko ngā reiti tika o te ±0.5% ki te ±1% o te tauine katoa, ahakoa i roto i ngā āhuatanga rere pōrearea, i te wā rānei kei roto i ngā wai ngā totoka iri. Mō tētahi tipu matū e whakaranu ana i ngā rauemi mata, ka whakarite tēnei taumata tika i te ōritetanga o te puranga, ka whakaiti i te para mai i te nui rawa, i te iti rawa rānei o te horopeta. Mō ngā mahi hinu me te hau, ka taea te aroturuki tika i ngā whakawhiti wahie, ka ārai i te ngaronga moni mai i ngā hapa ine. Heoi anō, he maha ngā EMF iti-tiaki hou kei roto ngā āhuatanga atamai pēnei i ngā whakaaturanga matihiko, ngā āheinga aroturuki mamao, me ngā whakatūpato tātaritanga-whaiaro. Mā ēnei taputapu ka taea e ngā kaiwhakahaere te aroturuki i ngā raraunga rere i te wā tūturu, te tautuhi i ngā take pea (hei tauira, ngā reiti rere rerekē) i mua i te piki haere, me te mahi i ngā whakatikatika mariko—ka whakaiti ake i te wā kore mahi. Hei tauira, ka taea e tētahi kaihanga rongoā te whakamahi i te aroturuki mamao hei whakarite kia tutuki te rere o te wai parakore i ngā paerewa FDA 24/7, me te kore e tuku tohunga hangarau ki ngā rūma ma mō ngā tirotiro auau.
I tēnei wā e kaha haere ana te pēhanga o ngā mahi ahumahi ki te whakaiti i ngā utu, ki te whakapai ake i te pumau, me te whakarei ake i te hua, ko ngā mita rere hikohiko iti-te-tiaki he otinga whai hua. Mā te hoahoa kore-wāhanga ka whakakorea ngā huringa tiaki utu nui, ka roa ake te roa o te ora o ngā taputapu, ka whakaitihia e te maha o ngā whakapaunga pūtea, ā, ka tiakina te kounga me te tutuki i ngā whakaritenga e te tika. Mō ngā kaiwhakahaere tipu me ngā tīma whakahaere, he mārama te pāngarau: ko te haumi ki tētahi EMF iti-te-tiaki ehara i te mea ko te hoko mita rere anake—engari ko te haumi ki te manawanui mahi mō te wā roa. Ahakoa e whakamahia ana ki te maimoatanga wai, ki te hanga, ki te whakaputa pūngao rānei, ka whakaatu ēnei taputapu ka taea te haere tahi te whai huatanga o te utu me te hiranga ine—ka huri i tētahi taputapu noa hei kaiārahi mō te angitu ahumahi.
