Scintillation detectorsanoshandiswa pakugadzirisa chikamu chepamusoro-simba che X-ray spectrum.Mu scintillation detectors zvinhu zve detector zvinonakidzwa ne luminescence (kubuda kwemifananidzo inooneka kana pedyo-inooneka) nemapikicha akabatwa kana zvidimbu.Huwandu hwemafotoni anogadzirwa hunoenderana nesimba reiyo yakatorwa yekutanga photon.Iwo mapurusi emwenje anounganidzwa nephoto-cathode.Maelectrons, anobudiswa kubva kuphotocathode, inokwidziridzwa neyakaiswa yakakwirira voltage uye inokwidziridzwa pane dynodes yeiyo yakasungirirwa photomultiplier.Pa detector inobuda electric pulse proportional kune yakabatwa simba inogadzirwa.Avhareji yesimba rinodiwa kugadzira erekitironi imwe paphotocathode inosvika mazana matatu eV.ForX-ray michina, muzviitiko zvakawanda NaI kana CsI makristasi akaiswa nawothalliumdzinoshandiswa.Aya makristasi anopa kujeka kwakanaka, yakakwirira photon inoshanda uye inogona kugadzirwa muhukuru hukuru.
Scintillation detectors inogona kuona huwandu hwemwaranzi yeionizing, kusanganisira alpha particles, beta particles, gamma rays uye X-rays.A scintillator yakagadzirirwa kushandura simba rechiitiko mwaranzi kuita inooneka kana ultraviolet mwenje, iyo inogona kuonekwa uye kuyerwa nesipm photodetector.Yakasiyana scintillator zvinhu zvinoshandiswa kumhando dzakasiyana dzemwaranzi.Semuenzaniso, organic scintillator inowanzoshandiswa kuona alpha nebeta particles, nepo inorganic scintillator ichiwanzo shandiswa kuona gamma rays neX-rays.
Sarudzo ye scintillator inoenderana nezvinhu zvakaita senge simba renji remwaranzi inozoonekwa uye nezvinodiwa chaizvo zvekushandisa.
