Kugwiritsa ntchito
Kuyendera chitetezo, ndondomeko yowunikira ndikuwunika anthu, zinthu, kapena madera kuti atsimikizire kuti akutsatira ndondomeko ndi malamulo a chitetezo, komanso kuzindikira ndi kuchepetsa kuopsa kwa chitetezo.Zimaphatikizapo kuyendera ndikuwunika mbali zosiyanasiyana, Kuwunika kwachitetezo kumachitika m'malo osiyanasiyana, kuphatikiza ma eyapoti, madoko, nyumba zaboma, zochitika zapagulu, zida zofunikira kwambiri, komanso mabizinesi apayekha.Zolinga zazikulu zowunikira chitetezo ndikulimbikitsa chitetezo ndi chitetezo cha anthu ndi katundu, kuletsa kulowa kwa zinthu zoletsedwa kapena zinthu zoopsa, kuzindikira ziwopsezo zomwe zingachitike kapena zigawenga, ndikusunga malamulo ndi bata.
Kuyang'ana kotengera, Poyang'anira chidebe, zowunikira zimagwiritsidwa ntchito kuzindikira zida zilizonse zotulutsa ma radio kapena magwero omwe angakhalepo mkati mwa chidebe.Zowunikirazi nthawi zambiri zimayikidwa pamalo ofunikira poyang'anira zotengera, monga polowera kapena potuluka, kuti awonetse ndikuwunika zomwe zili m'matumba.kuyang'anira ziwiya pazifukwa zosiyanasiyana, kuphatikiza: Kuwunika kwa radiation, Kuzindikira magwero a radioactive, Kupewa kuzembetsa anthu osaloledwa, Kuonetsetsa chitetezo cha anthu, ndi zina zambiri.
Kuyendera magalimoto olemera, imatanthawuza chipangizo chapadera kapena makina omwe amagwiritsidwa ntchito pozindikiritsa ndi kuyesa mbali zosiyanasiyana za magalimoto olemera, monga magalimoto, mabasi, kapena magalimoto akuluakulu ogulitsa malonda.Zowunikirazi zimagwiritsidwa ntchito nthawi zambiri poyang'ana, podutsa malire, kapena malo oyendera kuti zitsimikizire kuti zikutsatira chitetezo, malamulo, ndi malamulo.
NDT, chowunikira chomwe chimagwiritsidwa ntchito mu Mayeso Osawononga (NDT) chimatanthawuza chipangizo kapena sensa yomwe imagwiritsidwa ntchito kuti izindikire ndi kuyeza mitundu yosiyanasiyana ya discontinuity kapena zolakwika muzinthu kapena zomanga popanda kuwononga.Njira za NDT zimagwiritsidwa ntchito kwambiri m'mafakitale monga kupanga, zomangamanga, zamlengalenga, zamagalimoto, ndi zina zambiri kuyesa kukhulupirika, mtundu, ndi kudalirika kwa zida kapena zida.
Ore screening mafakitale, angatanthauze chipangizo kapena dongosolo lomwe limagwiritsidwa ntchito kuzindikira ndi kulekanitsa mchere wamtengo wapatali kapena zinthu zamtengo wapatali kuchokera ku miyala yamtengo wapatali panthawi yowunika.Zowunikirazi zidapangidwa kuti zizisanthula momwe zinthu ziliri komanso momwe zimapangidwira mu miyalayi ndikuwona mawonekedwe kapena zinthu zina zomwe zimakonda.X-ray kapena ma radiometric detector ndi kusankha kwa chowunikira m'mafakitale owunikira ore kutengera kapangidwe kake, mchere womwe ukufunidwa, komanso magwiridwe antchito komanso kulondola kofunikira pakuwunika.Zowunikirazi zimagwira ntchito yofunika kwambiri pakukulitsa kuchotsedwa kwa mchere wamtengo wapatali, kuchepetsa zinyalala, komanso kukhathamiritsa ntchito yonse yokonza miyala.
