INTENSIFYING Thiab fluorescent XOV XWM Thiab XERORADIOGRAPHY

Rau cov yeeb yaj kiab nthuav tawm thaum tsis muaj cov ntxaij vab tshaus cov cuam tshuam nyiaj bromide crystals raug faib thoob plaws tag nrho cov tuab ntawm emulsion thiab kev loj hlob ntev yog xav tau yog tias tag nrho cov no yuav tsum tau hloov mus rau hauv nyiaj.

Raws li, yuav ua li cas rau silver bromide nyob rau hauv lub teeb?

Thaum twg nyiaj bromide los yog AgBr khaws cia rau hauv tshav ntuj muaj tshuaj tiv thaiv tshwm sim . Chemical decomposition hu ua photo chemical reaction tshwm sim qhov twg nyiaj bromide hloov mus ua grey. Thaum peb khaws cov nyiaj bromide Nyob rau hauv tshav ntuj ces tom qab 2 mus rau 3 teev nws los ua Grey xim.

Vim li cas thiaj siv cov ntxaij vab tshaus siv hauv hluav taws xob? Intensifying cov ntxaij vab tshaus yog siv hauv x-ray cassette rau ua kom hnyav cov nyhuv ntawm cov x-ray photon los ntawm kev tsim ntau lub teeb photons. Nws txo qhov tshaj yuav tsum tau tsim ib qho kev ceev thiab chaw pib txo tus neeg mob koob ho.

Tsis tas li ntawd, cov ntxaij vab tshaus uas ua rau muaj zog yog dab tsi?

Ib intensifying npo yog ib daim ntawv yas coated nrog cov khoom siv fluorescent hu ua phosphor. Phosphors yog cov khoom siv uas hloov photon zog rau lub teeb.

Silver bromide siv rau dab tsi?

Siv : Vim nws lub teeb rhiab qhov xwm txheej, cov ntawv thov tseem ceeb ntawm nyiaj bromide yog nyob rau hauv kev yees duab. Nws yog siv nyob rau hauv kev yees duab films thiab daim hlau. Nws kuj yog siv rau infrared daim ntaub ntawv, rau lub teeb rhiab tsom iav, thiab semiconductors.
