Lub isotope lub neej ib nrab yog 13.22 Nws ; qhov lwj los ntawm electron capture rau tellurium-123 emits gamma hluav taws xob nrog lub zog tshaj ntawm 159 keV (qhov no yog gamma feem ntau siv rau kev yees duab).
Xav txog qhov no, ib nrab lub neej ntawm iodine 129 yog dab tsi?
Nws cov xov tooj cua nyob ntev tshaj isotope, 129 Kuv, muaj ib ib nrab - lub neej ntawm 15.7 lab xyoo, uas yog luv luv heev rau nws kom muaj nyob raws li qhov tseem ceeb nuclide.
Tom qab, lo lus nug yog, yuav ua li cas tshwm sim thaum iodine 123 nkag mus rau hauv lub cev? Iodine yog xav tau rau koj cov thyroid caj pas los tsim cov thyroid hormones. Yog radioactive heev iodine nkag mus koj lub cev , radioactive iodine tshuaj yuav rhuav tshem koj cov thyroid kom lub qog yuav tsum tsis ua cov tshuaj hormones. Ntau dhau radioactive iodine tshuaj hauv koj lub cev kuj tseem tuaj yeem ua rau cov qog ntshav qog ntshav lossis mob qog noj ntshav.
Ib tus tseem yuav nug, Kuv 123 nyob hauv koj lub cev ntev npaum li cas?
Cov yam ntxwv ntawm lub cev. Iodine- 123 decays los ntawm electron capture nrog a lub cev ib nrab-lub neej ntawm 13.2 Nws 1. Cov photon tias yog pab tau rau kev tshawb nrhiav thiab kev tshawb fawb yog teev nyob rau hauv Table 1.
Yuav siv iodine 123 li cas hauv tshuaj?
Sodium Iodide Ib - 123 yog ib tug radioactive isotope ntawm siv iodine hauv nuclear tshuaj kho mob rau kev kuaj mob ntawm cov kab mob thyroid. Tom qab kev tswj hwm qhov ncauj, Kuv - 123 yog nqus los ntawm txoj hnyuv thiab tau txais los ntawm cov qog ua haujlwm.
