Ngā hau onge(e mōhiotia ana ko ngā hau korekore), tae atu kite hēriuma (He), neon (Ne), ākoni (Ar),kripton (Kr), xenon (Xe), e whakamahia whānuitia ana i roto i ngā mara maha nā te mea he tino pumau ō rātou āhuatanga matū, kāore he tae, kāore he kakara, ā, he uaua ki te tauhohe. Koinei te whakarōpūtanga o ō rātou whakamahinga matua:

Hau tiaki: whakamahia tōna koretake matū hei ārai i te waikura, i te poke rānei

Te Whakarewa Ahumahi me te Whakarewa: Ka whakamahia te Argon (Ar) i roto i ngā tukanga whakarewa hei tiaki i ngā konganuku tauhohe pēnei i te konumohe me te konupora; i roto i te hanga haurua-ira, ka tiaki te argon i ngā anga silicon mai i te poke o ngā poke.

Te miihini tika: Ka tukatukahia te wahie karihi i roto i ngā tauhohenga ngota i roto i te taiao argon hei karo i te waikura. Te whakaroa i te roa o te ora o ngā taputapu: Mā te whakakī ki te hau argon, ki te hau krypton rānei ka whakaroa i te mimiti o te waea tungsten, ā, ka whakapai ake i te roa.

Ngā puna rama me ngā puna hiko

Ngā rama neon me ngā rama tohu: Ngā rama neon me ngā rama tohu: Ngā rama neon: (Ne) rama whero, e whakamahia ana i ngā taunga rererangi me ngā tohu pānuitanga; ka tukuna e te hau argon te rama kikorangi, ā, ka tukuna e te herium te rama whero.

Rama tino whai hua:Xenon (Xe)e whakamahia ana i roto i ngā rama mua me ngā rama rapu waka nā te mea he kanapa teitei, he roa hoki tōna ora;kriptone whakamahia ana i roto i ngā pūangi rama penapena hiko. Hangarau taiaho: E whakamahia ana ngā taiaho helium-neon (He-Ne) i roto i te rangahau pūtaiao, te maimoatanga hauora, me te matawai waeherepae.

Ngā tono poihau, waka rererangi me te ruku

Ko te iti o te mātotoru me te haumaru o te hīriama ngā mea matua.

Whakakapinga hauwai:Hīriamae whakamahia ana hei whakakī i ngā poihau me ngā waka rererangi, hei whakakore i ngā tūponotanga mura.

Te ruku hohonu: Ka whakakapia te hauota e Heliox hei ārai i te haurangi hauota me te paihana hāora i ngā ruku hohonu (i raro i te 55 mita).

Te tiaki hauora me te rangahau pūtaiao

Whakaahua Hauora: Ka whakamahia te hīriama hei whakamatao i roto i ngā MRI hei pupuri i te matao o ngā aukume kawe hiko nui.

Te Whakamamae me te Whakaora:Xenon, me ōna āhuatanga whakangote, e whakamahia ana i roto i te pokanga whakangote me te rangahau tiaki roro; e whakamahia ana te radon (radiation) i roto i te radiotherapy matepukupuku.

Te Whakamahinga Hiko: E whakamahia ana te hēriuma wai (-269°C) i ngā taiao tino iti te pāmahana, pērā i ngā whakamātautau kawe hiko me ngā whakatere matūriki.

Ngā hangarau matatau me ngā mara hou

Te Whakaterenga Ātea: E whakamahia ana te hīriama i roto i ngā pūnaha whakanui wahie rōkete.

Pūngao me ngā Rauemi Hou: Ka whakamahia te ākono i roto i te hanga pūtau rā hei tiaki i te parakore o ngā papa silicon; ka whakamahia te krypton me te xenon i roto i te rangahau me te whakawhanaketanga pūtau wahie.

Taiao me te Matawhenua: Ka whakamahia ngā isotope argon me te xenon hei aru i ngā pūtake parahanga o te hau me te whakatau i ngā tau matawhenua.

Ngā herenga rauemi: Kāore e taea te whakahou te hauhā, nō reira ka nui haere te hiranga o te hangarau hangarua.

Ko ngā hau onge, me tō rātou pumau, kanapa, iti te kiato, me ngā āhuatanga cryogenic, ka horapa ki ngā ahumahi, ki te rongoā, ki te rererangi, me te oranga o ia rā. I te whanaketanga hangarau (pēnei i te hanga pēhanga teitei o ngā matū helium), ka whānui haere tonu ā rātou tono, ka waiho hei "pou ngaro" e kore e taea te huna o te hangarau hou.
