NaI(Tl) e emetse sodium iodide e nang le thallium.Ke sesebelisoa sa scintillation se sebelisetsoang ho bona mahlaseli, haholo-holo mahlaseli a gamma.Ha mahlaseli a gamma a otla kristale ea NaI(Tl), e etsa hore liathomo tsa Tl li hlahise khanya ea leseli, e bonoang ke photocathode ebe e fetoloa lets'oao la motlakase.NaI(Tl) e atisa ho sebelisoa ho gamma spectroscopy, litšoantšo tsa bongaka, le ho hlahloba tikoloho.
Polycrystalline scintillator ke scintillator e entsoeng ka lithollo tse ngata tse nyenyane tsa kristale ho e-na le kristale e le 'ngoe e kholo e kang kristale e le' ngoe ea kristale.Likaroloana tsena tse nyane hangata li holisoa hammoho ka mokhoa o bitsoang solid-state sintering, moo likaroloana ka bomong li kopanang ebe li futhumatsoa ho fihlela li kopana.Sena se fapane le mokhoa o le mong oa ho hōla oa kristale o sebelisetsoang li-crystal scintillators tse le 'ngoe.Li-polycrystalline scintillator li na le melemo e mengata ho feta li-scintillator tse le 'ngoe tsa kristale, joalo ka litšenyehelo tse tlase tsa tlhahiso le botsitso bo ntlafalitsoeng ba mochini le mocheso.Leha ho le joalo, li ka 'na tsa e-ba le tharollo e tlaase ea matla le tlhahiso e tlaase ea khanya ha e bapisoa le li-crystal scintillator tse le' ngoe.
