Xray Physics 2 Flashcards
processing
solution temeratures affect the film
too hot= increase density
too cold= decrease density
processing factors
developer
rinse
fixer
washing
developer
brings out latent image by devleoping the exposed silver halide crystals
rinse
removed the exposed silver halide crystals
fixer
hardens the image
makes it permanent on the film
washing
removes developer and fixer
films always come out too dark?
light leak
developer temperature too hot
overexposure
films always too light?
developer temperature too low, chemicals need replacing
films brown?
inadequate developer
depleted fixer
inadequate wash water
milky films?
inadequate fixer
greasy films?
insufficient washing
increased fog?
old film
hot developer
contaminated chemicals
soft emulsion
insufficient fixing
static electricity does what to a film?
causes black and branching lightning like lines on film
rectifier
changes AC to DC
transformer
steps up or steps down the power
transducer
one form of energy to another
attenuation:
beam of radiation loses energy as it passes through matter
green or blue tint is added to?
base of xray film to reduce glare
