BGO Scintillator, Bgo Crystal, Bi4Ge3O12 Scintillator Crystal Ikiranga

ibisobanuro bigufi:

BGO (Bi₄Ge₃O₁₂) ni ibikoresho bya okiside.Ifite umubare munini wa atome, ubucucike bwinshi, imbaraga za mashini nziza, itari hygroscopique, nta clavage.Ubucucike bukabije cyane butuma iyi kristu ikwiranye cyane no kumenya radiyo isanzwe.BGO irashobora gukorerwa muburyo butandukanye na geometrie.

Ibisobanuro ku bicuruzwa

BGO (bismuth germanate) ni kirisiti ya scintillation ikozwe muri oxyde ya bismuth na oxyde ya germanium.Ifite ubucucike buri hejuru n'umubare munini wa atome, bigatuma biba byiza kumenya fotone ifite ingufu nyinshi.BGO scintillator ifite ingufu nziza zo gukemura no gusohora urumuri rwinshi, ibyo bikaba ingirakamaro mugutahura imirasire ya gamma nubundi bwoko bwimirasire ya ionizing.

Bimwe Mubisanzwe Byakoreshejwe BGO Crystal Harimo

1. Kwerekana amashusho yubuvuzi: BGO scintillator ikoreshwa kenshi muri positron yoherejwe na tomografiya (PET) kugirango imenye imirasire ya gamma itangwa na radioisotopi mumubiri.Bafite imbaraga nziza zo gukemura no kwiyumvisha ibintu ugereranije nizindi scintillator zikoreshwa mumashusho ya PET.

2. Ubushakashatsi bwa fiziki yingufu nyinshi: BGO kristal ikoreshwa mubushakashatsi bwa physics buke kugirango tumenye fotone ifite ingufu nyinshi, hamwe na hamwe, electron na positrons.Zifite akamaro kanini mugutahura imirasire ya gamma murwego rwingufu za 1-10 MeV.

3. Igenzura ryumutekano: Detector ya BGO ikoreshwa mubikoresho byo kugenzura umutekano nkimizigo hamwe na scaneri yimizigo kugirango hamenyekane ko hari ibintu bitera radio.

5. Gukurikirana ibidukikije: Ikimenyetso cya BGO gikoreshwa mugukurikirana ibidukikije kugirango hamenyekane imishwarara ya gamma ituruka ahantu nyaburanga nk'amabuye, ubutaka, n'ibikoresho byo kubaka.
