Product Description

Lead tungstate (PbWO₄/PWO) icrystal scintillation inowanzoshandiswa mukuedza kwefizikisi ine simba repamusoro pamwe nemumichina yekufungidzira yekurapa yakaita sePET (positron emission tomography) uye CT (computed tomography) scanner.Imwe yeakakosha zvimiro zvePWO, ine yakakwira density, iyo inobvumira PWO kutora gamma mwaranzi zvakanyanya kupfuura mamwe scintillation makristasi.Nekudaro, izvi zvinokonzeresa chiyero chepamusoro chechiratidzo-ku-ruzha uye zvirinani kutariswa kwemwaranzi.PWO makristasi anozivikanwa zvakare nekukasira nguva dzekupindura, izvo zvinoita kuti ive yakakodzera kune yakanyanya kumhanya data yekutora masisitimu.

Ivo zvakare vanoshingirira kukuvadzwa kwemwaranzi uye kugadzikana kwenguva refu, zvichiita kuti ive sarudzo yakavimbika kune yakaoma nharaunda application.Nekudaro, iyo yakaderera mwenje kubuda kwePWO makristasi kana ichienzaniswa nezvimwe scintillation zvinhu inodzikamisa kunzwa kwavo mune mamwe maapplication.Makristasi anowanzo kurira uchishandisa nzira yeCzochralski uye anogona kuumbwa kuita akasiyana siyana zvichienderana nekushandisa.PWO scintillator makristasi ane zvinotevera zvinofanirwa kucherechedzwa: PWO ine yakaderera mwenje kubuda.Iwo ari intrinsically radioactive zvichiita kuti isagamuchirwe kune mamwe maapplication.Ivo vanogona kukuvadzwa nemwaranzi.Kutanga nemadosi ari pakati pe1 uye gumi Gray (10² - 10³ rad).Uye kudzoreredzwa nenguva kana kuwedzeredza.
