Puas yog sodium iodide tawg?

Sodium iodide, nrog rau cov tshuaj formula NaI thiab CAS naj npawb 7681-82-5, yog ib tug dawb, crystalline khoom compound uas yog 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 qhov muaj peev xwm tawg tau. Hauv tsab xov xwm no, peb yuav tshawb nrhiav kev siv sodium iodide thiab hais cov lus nug, "Puas yog sodium iodide tawg?"

Sodium iodidefeem ntau yog siv nyob rau hauv cov tshuaj, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj nuclear. Nws yog siv rau hauv kev tsim cov iodine radioactive rau kev kuaj mob thiab kev kho mob ntawm cov thyroid kab mob. Tsis tas li ntawd, sodium iodide yog ua haujlwm nyob rau hauv cov chaw muag tshuaj, ua cov khoom noj khoom haus ntxiv, thiab hauv kev tsim cov tshuaj yees duab. Nws lub peev xwm los nqus X-rays thiab gamma rays ua rau nws muaj txiaj ntsig hauv kev tsim cov khoom siv hluav taws xob rau kev tshawb pom hluav taws xob.

Tam sim no, cia peb hais cov lus nug seb puas yogsodium iodideyog tawg. Hauv nws daim ntawv ntshiab, sodium iodide tsis suav tias yog tawg. Nws yog ib qho chaw ruaj khov nyob rau hauv ib txwm muaj mob thiab tsis pom cov khoom tawg. Txawm li cas los xij, zoo li ntau yam tshuaj, sodium iodide tuaj yeem hnov ​​​​mob nrog lwm cov tshuaj nyob rau hauv cov xwm txheej tshwj xeeb los tsim cov khoom tawg. Piv txwv li, thaum sodium iodide los rau hauv kev sib cuag nrog qee yam muaj zog oxidizing cov neeg ua haujlwm lossis cov hlau reactive, nws tuaj yeem ua rau muaj kev phom sij txaus ntshai. Yog li ntawd, thaum sodium iodide nws tus kheej tsis yog qhov tawg, nws yuav tsum tau ua tib zoo saib xyuas thiab khaws cia kom zoo kom tsis txhob muaj qhov xwm txheej tshwm sim.

Hauv cov ntsiab lus ntawm nws cov kev siv ntau yam,sodium iodidefeem ntau muaj kev nyab xeeb thaum ua raws li cov txheej txheem kev nyab xeeb tsim. Hauv kev siv tshuaj kho mob thiab tshuaj, nws yog siv raws li kev tswj xyuas los ntawm cov kws tshaj lij uas nkag siab txog nws cov khoom thiab muaj peev xwm txaus ntshai. Thaum siv rau hauv cov khoom siv hluav taws xob tshawb pom, sodium iodide tau muab ntim rau hauv cov khoom tiv thaiv kom muaj kev nyab xeeb thiab tiv thaiv kom tsis txhob raug mob rau cov tshuaj reactive.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov muaj peev xwm ua rau tawg tshwm sim nrog sodium iodide tsis yog tshwj xeeb rau qhov sib xyaw no ib leeg. Ntau cov tshuaj, thaum siv mishandled los yog ua ke nrog cov khoom tsis sib xws, tuaj yeem ua rau muaj kev pheej hmoo ntawm kev tawg. Yog li ntawd, kev tuav kom zoo, cia, thiab kev paub txog kev sib raug zoo ntawm cov tshuaj lom neeg yog qhov tseem ceeb hauv kev tiv thaiv kev sib tsoo thiab ua kom muaj kev nyab xeeb hauv ntau qhov chaw lag luam thiab kev tshawb fawb.

Hauv kev xaus, sodium iodide, nrog nwsCAS Nr .: 7681-82-5, yog ib qho khoom muaj txiaj ntsig nrog ntau hom kev siv, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj, tshuaj, thiab hluav taws xob kuaj pom. Txawm hais tias nws tsis yog qhov tawg, yuav tsum tau ceev faj kom tsis txhob muaj kev cuam tshuam nrog cov tshuaj tsis sib xws. Los ntawm kev nkag siab txog nws cov khoom thiab ua raws li cov txheej txheem kev nyab xeeb, sodium iodide tuaj yeem siv tau zoo thiab nyab xeeb hauv nws cov ntawv thov.
