Bismuth germanate (Bi4Ge3O12, BGO) yog cov khoom siv intrinsic scintillation muaj hwjchim loj haum. Vim nws siab zoo atomic number thiab kev kub ceev, BGO yog ib tug gamma heev npaum absorber muaj siab Diam duab nyhuv feem uas ua rau ib cov ncov Diam duab zoo heev los Compton piv. Nws yog tus tshaj oxide kuas scintillator.
BGO siv nyob rau hauv detectors particle physics, aerospace physics, nuclear tshuaj, kev geology, thiab lwm yam industries. BGO arrays los mus gamma mem tes spectroscopy. BGO muaju yeej tseem siv hauv positron emission tomography detectors. BGO detectors yog dua rau nruab nrab thiab suav high-energy gamma thiab high-energy physics daim ntaub ntawv.

Nta:
Tuab thiab muaj kev haum coefficient rau duab tshav gamma.
Lub teeb siab zis thiab hniav lwj me ntsis sij hawm, tsis muaj kob thiab tseeb
Daws teeb meem zoo zog thiab tso zis yam lub teeb.
Me thawj nyob hauv cov zis lub teeb ntawm 100° C
Tsis muaj yuav luag degradation los rau scintillation zog ntawm 10 * 6 gray.
