Isicelo
Ukuhlolwa kokhuseleko, inkqubo ecwangcisiweyo yokuhlola kunye nokuvavanya abantu, izinto, okanye iindawo zokuqinisekisa ukuthotyelwa kwemigaqo yokhuseleko kunye nemimiselo, kunye nokuchonga nokunciphisa imingcipheko yokhuseleko enokwenzeka.Kubandakanya ukuhlola kunye nokuphonononga iinkalo ezahlukeneyo, Ukuhlolwa koKhuseleko kuqhutywa kwiindawo ezahlukeneyo, kubandakanywa nezikhululo zeenqwelo-moya, ii-seaports, izakhiwo zikarhulumente, iziganeko zoluntu, izibonelelo ezibalulekileyo zeziseko ezingundoqo, kunye namashishini abucala.Iinjongo eziphambili zohlolo lokhuseleko kukuphucula ukhuseleko kunye nokhuseleko lwabantu kunye nempahla, ukuthintela ukungena kwezinto ezithintelweyo okanye izinto ezinobungozi, ukufumanisa izisongelo ezinokuthi zibe khona okanye izenzo zolwaphulo-mthetho, kunye nokugcina umthetho nocwangco.
Ukuhlolwa komgqomoKumxholo wokuhlolwa kwesikhongozeli, ii-detectors zisetyenziselwa ukuchonga nayiphi na imathiriyeli enokubakho yeradioactive okanye imithombo enokubakho ngaphakathi kwesikhongozeli.Ezi zichongi zidla ngokubekwa kwiindawo ezingundoqo kwinkqubo yokuhlolwa kweekhonteyina, ezinje ngeendawo zokungena okanye zokuphuma, ukuze zikhusele kwaye zijonge imixholo yezikhongozeli.ukuhlolwa kweekhonteyina ngeenjongo ezahlukeneyo, ezibandakanya: Ukuhlolwa kwemitha, Ukuchonga imithombo ye-radioactive, Ukuthintela ukurhweba ngokungekho mthethweni, Ukuqinisekisa ukhuseleko loluntu, njl.
Ukuhlolwa kwemoto enzima, ibhekisa kwisixhobo esikhethekileyo okanye inkqubo esetyenziselwa ukuchonga nokuvavanya imiba eyahlukeneyo yezithuthi ezinzima, njengeelori, iibhasi, okanye ezinye izithuthi ezinkulu zorhwebo.Ezi zichongi zidla ngokusetyenziswa kwiindawo zokukhangela, kwiindawo zokuwela imida, okanye kwizikhululo zokuhlola ukuqinisekisa ukuthotyelwa kokhuseleko, ulawulo kunye neemfuno zomthetho.
NDT, i-detector esetyenziswe kwi-Non-Destructive Testing (NDT) ibhekisela kwisixhobo okanye inzwa esetyenziselwa ukufumanisa nokulinganisa iintlobo ezahlukeneyo zokuyeka okanye iziphene kwizinto okanye izakhiwo ngaphandle kokubangela umonakalo kubo.Ubuchule be-NDT busetyenziswa kakhulu kumashishini afana nokuvelisa, ulwakhiwo, i-aerospace, iimoto, kunye nokunye ukuvavanya ukuthembeka, umgangatho, kunye nokuthembeka kwamacandelo okanye imathiriyeli.
Amashishini okuhlola i-Ore, inokubhekisela kwisixhobo okanye inkqubo esetyenziselwa ukuchonga kunye nokwahlula iiminerali ezixabisekileyo okanye izinto kwintsimbi ekrwada ngexesha lenkqubo yokuhlola.Ezi zichongi ziyilelwe ukuhlalutya iimpawu ezibonakalayo kunye neekhemikhali zentsimbi ekrwada kwaye zikhangele iimpawu ezithile okanye izinto ezinomdla.I-X-reyi okanye i-radiometric detectors lukhetho lwe-detector kumashishini okuhlola i-ore ixhomekeke ekubunjweni okukodwa kwe-ore, iiminerali ezifunwayo, kunye nokusebenza kunye nokuchaneka okufunekayo kwinkqubo yokuhlola.Ezi zichongi zidlala indima ebalulekileyo ekwandiseni ukugrunjwa kwezimbiwa ezixabisekileyo, ukucutha inkunkuma, kunye nokwandisa imisebenzi yokusetyenzwa kwentsimbi.
