Mafotokozedwe Akatundu
BGO (bismuth germanate) ndi crystal scintillation yopangidwa ndi bismuth oxide ndi germanium oxide.Ili ndi kachulukidwe kwambiri komanso nambala ya atomiki yokwera kwambiri, zomwe zimapangitsa kuti ikhale yabwino kuzindikira ma photon amphamvu kwambiri.Ma scintillator a BGO ali ndi mphamvu yabwino yosinthira mphamvu komanso kutulutsa kwamphamvu kwambiri, komwe kumawapangitsa kukhala othandiza pozindikira kuwala kwa gamma ndi mitundu ina ya ma radiation ya ionizing.
Zina Zomwe Zimagwiritsidwa Ntchito pa BGO Crystals Zimaphatikizanso
1. Kujambula kwachipatala: BGO scintillators nthawi zambiri amagwiritsidwa ntchito mu positron emission tomography (PET) scanner kuti azindikire kuwala kwa gamma komwe kumatulutsidwa ndi radioisotopes m'thupi.Amakhala ndi mphamvu zabwino kwambiri zosinthira mphamvu komanso kumva bwino poyerekeza ndi ma scintillator ena omwe amagwiritsidwa ntchito pazithunzi za PET.
2. Kuyesera kwa physics yamphamvu kwambiri: Makristasi a BGO amagwiritsidwa ntchito poyesera particle physics kuti azindikire ma photon amphamvu kwambiri ndipo, nthawi zina, ma electron ndi positrons.Ndiwothandiza kwambiri pozindikira kuwala kwa gamma mu mphamvu ya 1-10 MeV.
3. Kuyang'anira chitetezo: Zowunikira za BGO nthawi zambiri zimagwiritsidwa ntchito pazida zowunikira chitetezo monga zojambulira katundu ndi katundu kuti azindikire kukhalapo kwa zinthu zotulutsa ma radio.
4. Kafukufuku wa Nuclear physics: Makristalo a BGO amagwiritsidwa ntchito poyesera nyukiliya ya nyukiliya kuti ayese mawonekedwe a gamma ray otulutsidwa ndi zochita za nyukiliya.
5. Kuyang'anira chilengedwe: Zowunikira za BGO zimagwiritsidwa ntchito poyang'anira chilengedwe kuti zizindikire ma radiation a gamma kuchokera kuzinthu zachilengedwe monga miyala, nthaka, ndi zomangira.
