Nkhani Zoyang'anira Chitetezo
Kodi kuyendera chitetezo ndi chiyani?
Zomwe zimayambitsa kuzindikirika kwa ma radiation zimawonekera muzolakwika zazikulu zitatu zomwe zimalepheretsa kutumizidwa kwawo moyenera pazogwiritsa ntchito chitetezo:
1.Kuvuta kuzindikira modalirika zida zanyukiliya zotetezedwa
2.Kuchuluka kwa ma alarm alarm chifukwa cha radioactivity yachilengedwe
3.Poizoni, zodula, kapena zosapezeka zojambulira zida zomwe zimalepheretsa kukulitsa kukhudzika kofunikira.
KINHENG Materials imapereka zinthu zowoneka bwino zogwiritsidwa ntchito monga Scintillator Chimene ndi chimodzi mwazinthu zamagetsi zomwe zimagwiritsidwa ntchito ndipo zimatembenuza mphamvu ya X-ray kukhala kuwala.Kinheng Materials wapereka CWO (CdWO4) scintillator.Imakhala ndi chidwi chachikulu, ikangowala komanso kukana kwambiri kwa X-ray, ndipo imakhala ngati zinthu zofunika kwambiri pakuwunika mwachangu kwa X-ray tomography, zida zojambulira zapamwamba komanso kujambula zithunzi za X-ray m'munda woyendera mafakitale.
Cholinga chathu ndikukulitsa kugwiritsa ntchito kwa mafakitale kwa ma scintillator potengera njira yathu yopangira ukadaulo wokhazikitsidwa ndi zida zopangira ukadaulo komanso kumvetsetsa kwa mawonekedwe a kuwala kwa ma scintillator omwe amapezeka pantchito yachipatala.Izi ndizo, ma scintillator a machitidwe osiyanasiyana oyendera ma X-ray a katundu wapaulendo pa eyapoti ndi doko, katundu wozembetsa, kulowa ndi kutuluka mosaloledwa, malire, zinthu zakunja muzakudya ndi zolakwika m'mapangidwe ovuta.
Zida zathu zimakuthandizani kuti mukhale ndi mawonekedwe apamwamba a X-ray, kuyang'ana katundu wothamanga kwambiri ndikusanthula mwachangu, kutalika kwa moyo wa machubu a X-ray ndi kuchepetsa kukula kwa zida za X-ray zomwaza ndi zida zazing'ono zotchinjiriza.
Kodi Kingheng angapereke chiyani?
CsI (Tl) scintillator gulu
Mizere ya CsI(Tl) 1-D imagwiritsidwa ntchito kwambiri mu scanner yowunikira Chitetezo mu Subway, doko, eyapoti, malire ndi zina. Cz yathu kukula CsI(Tl) ili ndi kuwala kocheperako, zomwe zipangitsa kuti filimuyi ikhale yomveka bwino.Zinthu zokhazikika za pixel 8, zinthu 16.Kusintha mwamakonda kuli muutumiki.
CWO (CdWO4) scintillator array
Imakhala ndi chidwi chachikulu, ikangowala komanso kukana kwambiri kwa X-ray, ndipo imakhala ngati zinthu zofunika kwambiri pakuwunika mwachangu kwa X-ray tomography, zida zojambulira zapamwamba komanso kujambula zithunzi za X-ray m'munda woyendera mafakitale.
GAGG: Zambiri
1D, 2D GAGG:Ce arraya ilipo.Zomwe zimawala ka 4 kuposa CWO pamagawo apamwamba amphamvu.
