100
This is the acronym for a common type of personnel dosimeter.
What is TLD?
100
These are the four required elements for x-ray production.
What is a vacuum, a source of electrons, a target, and a high potential difference?
100
This is the standard control limit for the field light to radiation field alignment test.
What is +/-2% of SID?
100
This is the action of the developer in the automatic film processor.
What is changes the exposed silver halide crystals into black, metallic silver?
100
Scatter radiation fog increases if the amount of irradiated tissue does this.
What is increases?
200
This is the recommended placement for a personnel device dosimeter on the body of the limited operator.
What is the badge should be worn in the region of the collar on the anterior surface of the body and outside the lead apron, if worn?
200
This is what the greatest portion of the x-ray beam is made up of.
What is Bremsstrahlung radiation?
200
This is the standard control limit for the beam (central ray) alignment test.
What is within 1 degree of perpendicular?
200
During digital image processing, electronic collimation (masking) should not be used to replace this.
What is proper radiographic collimation?
200
This is the most effective and practical way to reduce scatter radiation fog on a radiograph.
What is use a grid or Bucky?
300
This is the NCRP recommended annual effective dose limit for occupational exposure.
What is 5.0rem (0.05 Sv)?
300
By varying this, one can control the penetrating power of the x-ray beam.
What is Kilovoltage (kVp)?
300
This is how often lead aprons and gloves should be checked for cracks or holes.
What is every 6 months?
300
Computed radiography eliminated the need for this.
What is a darkroom?
300
The general rule states a grid should be employed when the part thickness is greater than this.
What is 12cm?
400
This is the percentage of the annual occupational effective dose limit, when likely to be received, requires radiation monitoring of personnel.
What is 10%?
400
This is the process in which a neutral atom gains or loses an electron.
What is ionization?
400
This is how detector fog can be prevented when using computed radiography cassettes.
What is protect the cassette before and after exposure?
400
These are the conditions that are most important for optimum viewing of radiographic images.
What is low room light level?
400
Technique charts are based on patient part measurements obtained using an x-ray caliper and are expressed as this.
What is thickness in centimeters?
500
This is the conventional (British system) radiation unit used to express radiation intensity in air.
What is Roentgen?
500
This is the smallest possible unit of electromagnetic energy and may be thought of as a tiny "bundle" of energy.
What is a photon?
500
The artifact that is caused by inadequate exposure technique.
What is quantum mottle?
500
This is the terms for marks, exposures, or images on a radiograph that are not a part of the intended image.
What are artifacts?
500
If present, this is how the anode heel effect would be seen on an image.
What is the image will be lighter on the anode end than on the cathode end?
