Lisebelisoa tsa scintillationli sebelisetsoa ho etsa qeto ea karolo e phahameng ea matla ea mahlaseli a X-ray.Ka li-detectors tsa scintillation, thepa ea mochine e thabela ho luminescence (ho tsoa ha li-photon tse khanyang tse bonahalang kapa tse haufi-ufi) ke li-photon kapa likaroloana tse monyelitsoeng.Palo ea li-photon tse hlahisoang li lekana le matla a photon ea mantlha e monyelitsoeng.Li-pulses tse khanyang li bokelloa ke photo-cathode.Lielektrone, tse tsoang hophotocathode, li potlakisoa ke matla a phahameng a sebelisoang 'me li holisoa ho li-dynodes tsa photomultiplier e khomaretsoeng.Sehlahisoang sa detector ho hlahisoa pulse ea motlakase e lekanang le matla a monyelitsoeng.Ka karolelano matla a hlokahalang ho hlahisa elektrone e le 'ngoe ho photocathode ke hoo e ka bang 300 eV.Bakeng saLisebelisoa tsa X-ray, maemong a mangata likristale tsa NaI kapa CsI li kentsoe kathalliumdi sebedisoa.Likristale tsena li fana ka ponahalo e ntle, e phahameng ea photon e sebetsang hantle 'me e ka hlahisoa ka boholo bo boholo.
Li-scintillation detectors li khona ho lemoha mahlaseli a mangata a ionizing, ho akarelletsa le likaroloana tsa alpha, likaroloana tsa beta, mahlaseli a gamma le X-rays.Scintillator e etselitsoe ho fetolela matla a mahlaseli a kotsi hore e be leseli le bonahalang kapa la ultraviolet, le ka bonoang le ho lekanyetsoa kasipm photodetector.Lisebelisoa tse fapaneng tsa scintillator li sebelisoa bakeng sa mefuta e fapaneng ea mahlaseli.Mohlala, organic scintillator hangata e sebelisoa ho bona likaroloana tsa alpha le beta, athe inorganic scintillator e atisa ho sebelisoa ho bona mahlaseli a gamma le X-ray.
Khetho ea scintillator e ipapisitse le lintlha tse joalo ka mefuta ea matla a mahlaseli a lokelang ho bonoa le litlhoko tse ikhethileng tsa ts'ebeliso.
