Sodium iodide, nrog tshuaj mis nyuj NAI thiab CAS & CAS NUMBER 7681-82-5, yog dawb, crystalline khoom sib xyaw uas feem ntau siv nyob rau hauv ntau yam kev siv. Txawm li cas los xij, muaj cov lus nug thiab kev txhawj xeeb txog nws cov peev xwm tawg. Hauv tsab xov xwm no, peb yuav tshawb txog kev siv sodium iodide thiab hais cov lus nug, "yog sodium iodigle tawg?"
Sodium iodidefeem ntau siv nyob rau hauv thaj chaw ntawm cov tshuaj, tshwj xeeb yog nyob rau hauv cov tshuaj nuclear. Nws yog siv hauv kev tsim cov khoom siv xov tooj cua rau kev kho mob thiab kev kho cov qog cov thyroid-cuam tshuam. Ib qho ntxiv, sodium iodide yog ua haujlwm hauv cov kws tshuaj, ua cov khoom noj muaj txiaj ntsig, thiab kev tsim khoom ntawm cov duab thaij duab. Nws lub peev xwm ua tau zoo dua X-Rays thiab Gamram rays ua rau nws muaj txiaj ntsig nyob rau hauv kev tsim cov scintillation ntes rau kev kuaj kom muaj hluav taws xob.
Tam sim no, cia qhov chaw nyob cov lus nug ntawm sebsodium iodideyog tawg. Hauv nws daim ntawv ntshiab, sodium iodide tsis suav tias yog tawg. Nws yog qhov chaw ruaj khov nyob rau hauv ib txwm muaj mob thiab tsis yog kev nthuav dav cov khoom. Txawm li cas los xij, zoo li ntau cov tshuaj lom neeg tshuaj, sodium iodide tuaj yeem ua rau lwm cov chaw sib txuas ua ke rau cov kev sib xyaw tshwj xeeb. Piv txwv li, thaum Sodium iodide tuaj rau hauv kev sib chwv nrog qee tus neeg muaj zog oxidizing cov neeg sawv cev lossis cov hlau reactive, nws tuaj yeem ua rau muaj kev phom sij. Yog li ntawd, thaum sodium iodide nws tus kheej tsis tau txais kev lom zem, nws yuav tsum tau daws nrog kev saib xyuas thiab khaws cia kom tiv thaiv ib qho kev huam yuaj.
Nyob rau hauv cov ntsiab lus ntawm nws ntau yam siv,sodium iodideFeem ntau nyab xeeb thaum nqa raws li cov lus qhia kev nyab xeeb tsim. Hauv kev siv tshuaj kho mob thiab chaw muag tshuaj, nws tau siv nyob rau hauv cov kev tswj hwm los ntawm cov kws tshaj lij uas nkag siab txog nws cov peev txheej thiab muaj kev phom sij. Thaum siv nyob rau hauv cov khoom siv hluav taws xob nrhiav, sodium iodide yog ntim rau hauv kev tiv thaiv kev nyab xeeb kom muaj kev nyab xeeb thiab tiv thaiv ib qho kev huam yuaj rau cov tshuaj uas muaj kev cuam tshuam.
Nws yog ib qho tseem ceeb kom nco ntsoov tias qhov muaj peev xwm rau cov kev tawm tsam tau muaj kev cuam tshuam nrog Sodium iodide tsis tshwj xeeb rau qhov sib txuas no ib leeg. Ntau yam tshuaj lom neeg, thaum mishandled lossis sib xyaw ua ke nrog cov tshuaj tsis sib xws, tuaj yeem ua rau muaj kev pheej hmoo ntawm kev tawg. Yog li ntawd, tsim nyog tuav, cia, thiab paub txog kev sib xyaw ua ke yog qhov tseem ceeb hauv kev tiv thaiv ntau yam kev lag luam thiab kev tshawb fawb.
Hauv kev xaus, sodium iodide, nrog nwsCAS naj npawb 7681-82-5, yog qhov tseem ceeb compound nrog ntau cov ntawv thov, tshwj xeeb rau hauv cov teb ntawm cov tshuaj, chaw tshuaj, thiab khoom siv hluav taws xob. Thaum nws tsis tau txais qhov tawg tau tawg, ceev faj yuav tsum tau coj los tiv thaiv qee yam kev cuam tshuam nrog cov tshuaj tsis sib xws. Los ntawm kev nkag siab txog nws cov khoom thiab ua raws li kev nyab xeeb cov txheej txheem, sodium iodide tuaj yeem siv tau zoo thiab nyab xeeb hauv nws cov ntawv thov.
