Answer:

Increase either or both Question 2: Anyone working with or in the vicinity of ah x-ray machine should use what

Answer:

a dosimetery badge

Question 3: How does kVp affect electrons and the x-ray beam

Answer:

increasing it increases the speed at which electrons are pulled from the cathode to the anode and also increases the penetrating power of the x-ray beam

Answer:

2.5 mm

Question 12: What is the purpose of the collimator on an x-ray machine

Answer:

limits the primary beam size

Question 13: If the radiograph is too light and the image appears under-penetrated you should

Answer:

Answer:

clear

Question 21: When evaluating a film is too light, You then determine that the film does not have adequate penetrations the best adjustment to make is

Answer:

Increase kVp Question 22: Because of the relationship between milliamp and mAs, as you increase the mA you can

Answer:

Decrease the length of the exposure so that there is less chance of movement

Question 23: what is suffested mAs settings for the thorax

Answer:

5

Question 24: what is the proper order of manual processing of x-ray film

Answer:

potential light leaks, exhausted chemicals, poor development techniques
