Question 5

During manufacturing, dye is added to the base of most radiographic film to slightly tint the film ——

whyy?

Answer 5

Blue, this coloring reduces eyestrain and fatigue,
enhancing radiologists diagnostic efficiency and accuracy

Answer 19

Protective coating

Question 20

-Active layer of the radiographic intensifying screen
——- (?)converts the x ray beam into light

Answer 20

Phosphor layer, Phosphor

Question 21

Favorable properties of radiographic intensifying screen phosphor layer

Answer 21

-High atomic number
-High conversion efficiency
-Appropriate spectral matching
-minimal phosphoresence
-Not affected by heat, humidity or other environmental conditions

Question 22

In the intensifying screen, what do you call the process where light is produced

Answer 22

Luminescence

Question 23

2 types of luminescnece

Answer 23

Fluorescence and Phosphorescence

Question 24

Difference between Phosphorescence and Luminescence

Answer 24

Phosphorescence is when it is during and after the stimulation, it’ll still glow

Luminescence needs the stimulation of x ray, that’s the fluorescence
