In film radiography, penetrameters are usually placed;

Three liquids which are essential to process an exposed film properly are:

The two most common causes for excessively high-density radiographs are:

If a film is placed in a developer solution and allowed to develop without any agitation:

Fluorescent intensifying screens are usually mounted in pairs in rigid holders called:

Which of the following materials is suitable for use in vessel or pails and used to mix processing solutions?

As a check on the adequacy of the radiographic technique, it is customary to place a standard test piece on the source side of the specimen. This standard test piece is called a:

Kilovoltage, exposure time, and source-to-film distance are three of the most important X-ray exposure factors that can be controlled. A fourth such exposure factor is:

The normal development time for manually processing X-ray film is:

One requirement for keeping fluorescent screens in good condition is that they must:

An unshielded isotope source gives a dosage rate of 900 mR/h at 3 m (10 ft). What would the unshielded dosage rate be at 9 m (30 ft)?

The lead symbol “B” is attached to the back of the film holder to determine:

What is som0etimes used to change the alternating current from the high voltage transformer to direct current for the purpose of increasing the X-ray machine output?

Approximately, what percent of the original radioactivity is left after 6 half-lives?

Survey meters provide:

A filter will reduce the amount of __________ in the primary radiation beam.

If we are to maintain the same exposure but must decrease the source-to-film distance, we must ________ the time of exposure

An artifact is a film defect that results from lack of cleanliness, or improper film handling or processing.

What is the purpose of the developing solution?

With a given exposure time and kilovoltage, a properly exposed radiograph is obtained with a 6 mA-minutes exposure at the distance of 51 cm (20 in.). It is desired to increase the sharpness of detail in the image by increasing the source-to-film distance to 102 cm (40 in.). The correct milliamperage-minutes exposure to obtain the desired radiographic density at the increased distance is:
