Ni ubuhe bwoko bw'imirasire ishobora gutahura?

Ibikoresho bya Scintillationzikoreshwa mukugena igice kinini cyingufu za X-ray.Muri disikete ya scintillation ibikoresho bya detector byishimiye luminescence (gusohora fotone igaragara cyangwa hafi-igaragara ya fotone yumucyo) na fotone cyangwa ibice byinjijwe.Umubare wa fotone yakozwe ugereranije ningufu za fotone yibanze yakiriwe.Imbuto zoroheje zegeranijwe nifoto- cathode.Electron, yasohotse muriYamazaki, byihutishwa na voltage ikoreshwa kandi ikongerwaho kuri dynode ya fotomultiplier.Kuri detector isohoka amashanyarazi ahwanye ningufu zinjiye zirakorwa.Impuzandengo yingirakamaro ikenewe kugirango ikore electron imwe kuri Photocathode ni 300 eV.KuriIkirangantego, mubihe byinshi NaI cyangwa CsI kristu ikora hamwethalliumByakoreshejwe.Izi kristu zitanga umucyo mwiza, fotone ikora neza kandi irashobora gukorwa mubunini.

Disikete za Scintillation zirashobora kumenya imirasire ya ionizing, harimo uduce twa alfa, uduce twa beta, imirasire ya gamma na X-X.Scintillator yagenewe guhindura ingufu z'imirasire y'ibyabaye mu mucyo ugaragara cyangwa ultraviolet, ushobora gutahurwa no gupimwa na asipm Photodetector.Ibikoresho bitandukanye bya scintillator bikoreshwa muburyo butandukanye bwimirasire.Kurugero, scintillator organique ikoreshwa mugutahura alfa na beta, mugihe scintillator idasanzwe ikoreshwa mugutahura imirasire ya gamma na X-X.

Guhitamo scintillator biterwa nibintu nkurwego rwingufu zumuriro ugomba kumenyekana nibisabwa byihariye mubisabwa.
