Phosphorus - 32 yog ib qho kev siv radionuclide nrog ib nrab-lub neej ntawm 14.3 hnub, emitting beta hais nrog lub zog siab tshaj plaws ntawm 1.71 MeV (Million Electron Volts). Cov beta hais mus rau qhov siab tshaj plaws ntawm 20 ko taw hauv huab cua ntawm lub zog siab tshaj plaws. Saib daim ntawv qhia hauv qab no kom paub txog tus nqi twg P - 32 lwj.
Ib yam li ntawd ib tug yuav nug, hom hluav taws xob twg phosphorus 32 tso tawm?
Phosphorus-32 Iav Microspheres P yog ib lub xov tooj cua uas tso tawm lub zog β-particles thaum lwj. Nws muaj ib ib nrab neej ntawm 14.28 hnub thiab cov ntaub so ntswg nkag siab tshaj plaws ntawm 8 hli, nrog qhov nruab nrab ntawm 3.2 hli (Wong et al, 1999).
Tsis tas li ntawd, koj sau phosphorus 32 li cas? Phosphorus - 32 | H3P - PubChem.
Yog li ntawd, Phosphorus 32 puas yog ib qho tsis muaj hluav taws xob isotope?
Phosphorus - 32 ( 32P ) yog a radioactive isotope ntawm phosphorus . Phosphorus - 32 tsuas muaj nyob rau hauv me me nyob rau hauv lub ntiaj teb no raws li nws muaj ib tug luv luv ib nrab-lub neej ntawm 14.29 hnub thiab thiaj li decays sai heev.
Kev siv phosphorus 32 yog dab tsi?
Chromic phosphate P 32 yog siv los kho mob qog noj ntshav lossis muaj teeb meem ntsig txog. Nws yog muab tso rau hauv catheter rau hauv lub pleura (sac uas muaj lub ntsws) los yog mus rau hauv lub peritoneum (sac uas muaj lub siab, plab, thiab txoj hnyuv) los kho cov kua dej nyob rau hauv cov cheeb tsam uas yog tshwm sim los ntawm cancer.
