Ndi mtundu wanji wa ma radiation omwe mungazindikire scintillation detector?

Ma scintillation detectorsamagwiritsidwa ntchito pozindikira gawo lamphamvu kwambiri la X-ray sipekitiramu.Mu scintillation detector zinthu za chojambulira zimakondwera ndi luminescence (kutulutsa kwa mafotoni owoneka kapena owoneka pafupi) ndi mafotoni kapena tinthu tating'onoting'ono.Chiwerengero cha ma photon opangidwa ndi ofanana ndi mphamvu ya photon yoyamba yotengedwa.Miyendo yowala imasonkhanitsidwa ndi photo-cathode.Ma electron, opangidwa kuchokera kuphotocathode, amafulumizitsidwa ndi mphamvu yamagetsi yogwiritsidwa ntchito ndipo amakulitsidwa pa dynodes ya photomultiplier yophatikizidwa.Pa chowunikira chotulutsa mphamvu yamagetsi yofanana ndi mphamvu yotengedwa imapangidwa.Avereji ya mphamvu zofunika kupanga elekitironi imodzi pa photocathode ndi pafupifupi 300 eV.ZaX-ray zowunikira, nthawi zambiri NaI kapena CsI makhiristo adamulowetsa ndithalliumamagwiritsidwa ntchito.Makhiristo awa amapereka kuwonekera bwino, kugwiritsa ntchito bwino kwa photon ndipo kumatha kupangidwa mokulirapo.

Ma scintillation detectors amatha kuzindikira mitundu ingapo ya cheza ionizing, kuphatikiza tinthu tating'onoting'ono ta alpha, tinthu ta beta, cheza cha gamma ndi X-ray.Scintillator idapangidwa kuti isinthe mphamvu ya radiation kuti iwoneke kapena kuwala kwa ultraviolet, komwe kumatha kuzindikirika ndikuyezedwa ndisipm photodetector.Zida zosiyanasiyana za scintillator zimagwiritsidwa ntchito pamitundu yosiyanasiyana yama radiation.Mwachitsanzo, organic scintillator imagwiritsidwa ntchito pozindikira tinthu tating'onoting'ono ta alpha ndi beta, pomwe inorganic scintillator imagwiritsidwa ntchito pozindikira kuwala kwa gamma ndi X-ray.

Kusankhidwa kwa scintillator kumatengera zinthu monga kuchuluka kwa mphamvu zama radiation zomwe zikuyenera kuzindikirika komanso zofunikira pakugwiritsa ntchito.
