Iodide yesodium, kunye ne-chemical formula NaI kunye nenombolo ye-CAS 7681-82-5, i-white, i-crystalline i-compound eqinile esetyenziswa ngokuqhelekileyo kwizicelo ezahlukeneyo. Nangona kunjalo, kuye kwakho imibuzo kunye neenkxalabo malunga neempawu zayo ezinokuthi ziqhume. Kweli nqaku, siza kuphonononga ukusetyenziswa kwe-sodium iodide kwaye siphendule umbuzo othi, "Ngaba iodide yesodium iyaqhuma?"
Iodide yesodiumisetyenziswa ikakhulu kwicandelo lamayeza, ngakumbi kumayeza enyukliya. Isetyenziselwa ukuveliswa kwe-iodine ye-radioactive kwi-imaging yezonyango kunye nokunyangwa kweemeko ezinxulumene ne-thyroid. Ukongeza, i-sodium iodide isetyenziswa kumayeza, njengesongezelelo sesondlo, nakwimveliso yeekhemikhali zeefoto. Ukukwazi ukufunxa ngokufanelekileyo ii-X-reyi kunye nemitha ye-gamma kuyenza ixabiseke kwimveliso ye-scintillation detectors ukuze ibonwe ngemitha.
Ngoku, makhe siphendule umbuzo wokubasodium iodideiyaqhuma. Ngendlela ecocekileyo, iodide yesodium ayithathwa njengento eqhumayo. Yikhompawundi ezinzile phantsi kweemeko eziqhelekileyo kwaye ayibonisi iipropati eziqhumayo. Nangona kunjalo, njengemichiza emininzi, iodide yesodium inokusabelana nezinye iikhompawundi phantsi kweemeko ezithile zokwenza imixube eqhumayo. Ngokomzekelo, xa i-iodide yesodium idibana nee-agent ezithile ezinamandla ze-oxidizing okanye isinyithi esisebenzayo, inokukhokelela ekuphenduleni okunokuba yingozi. Ke ngoko, ngelixa i-sodium iodide ngokwayo ayiqhumi ngokwemvelo, kufuneka iphathwe ngononophelo kwaye igcinwe ngokufanelekileyo ukuthintela nakuphi na ukusabela ngengozi.
Kwimixholo yokusetyenziswa kwayo eyahlukeneyo,sodium iodideikhuselekile ngokubanzi xa iphathwa ngokwezikhokelo zokhuseleko ezisekiweyo. Kwizicelo zonyango kunye namayeza, isetyenziswe phantsi kweemeko ezilawulwa ngabaqeqeshi abaqeqeshiweyo abaqonda iimpawu zayo kunye nobungozi obunokwenzeka. Xa isetyenziswe kwisixhobo sokubona i-radiation, iodide ye-sodium ivalwe kwii-casings zokukhusela ukuqinisekisa ukhuseleko kunye nokuthintela nakuphi na ukuvezwa ngengozi kwizinto ezisebenzayo.
Kubalulekile ukuqaphela ukuba amandla okuqhuma okubandakanya iodide yesodium ayiyodwa kule khompawundi yodwa. Iikhemikhali ezininzi, xa zingaphathwa kakuhle okanye zidityaniswe nezinto ezingahambelaniyo, zinokubeka umngcipheko wokudubula. Ke ngoko, ukuphathwa ngokufanelekileyo, ukugcinwa, kunye nolwazi lokuhambelana kweekhemikhali kubalulekile ekuthinteleni iingozi kunye nokuqinisekisa ukhuseleko kwiindawo ezahlukeneyo zoshishino nezesayensi.
Ukuqukumbela, iodide yesodium, kunye nayoInombolo ye-CAS 7681-82-5, yikhompawundi exabisekileyo enezicelo ezahlukeneyo, ngakumbi kwiinkalo zamayeza, amayeza, kunye nokufunyanwa ngemitha. Ngelixa ingaqhushumba ngokwemvelo, amanyathelo okhuseleko kufuneka athathwe ukuthintela nakuphi na ukusabela okunokubakho ngezinto ezingahambelaniyo. Ngokuqonda iipropathi zayo kunye nokulandela iiprothokholi zokhuseleko, iodide yesodium ingasetyenziswa ngokufanelekileyo nangokukhuselekileyo kwizicelo ezijoliswe kuzo.
