Question 1

If the densities seen on the daily radiographs appear darker than those seen on the reference radiographs, the developer solution is (1) weak, (2) too concentrated, (3) cold, and/or (4) too warm.

Accepted Answer

If the densities on the radiographs appear darker, it indicates that the developer solution is too concentrated or too warm, leading to overdevelopment.

Question 2

The clearing test is used to monitor:

Accepted Answer

The clearing test is a test performed on fixer solution to monitor its strength. It is used to determine whether the fixer has become exhausted and needs to be replenished or replaced. The other options listed are not related to the clearing test.

Question 3

When the stepwedge technique is used to evaluate developer strength, if the density on the daily radiograph differs from that on the standard radiograph by more than ____ steps, the developer solution is depleted.

Accepted Answer

If the density on the daily radiograph differs from that on the standard radiograph by more than two steps, it indicates that the developer solution is depleted and needs to be replaced.

Question 4

If the film clears in ____ minutes, the chemistry is of adequate strength.

Accepted Answer

If the film clears in 2 minutes,the chemistry is of adequate strength.

Question 5

The stepwedge technique for evaluating developer strength relies on exposing one exposed stepwedge film:

Accepted Answer

The stepwedge technique involves processing a film with multiple steps of known density, and evaluating the resulting image to determine the quality of the developer used. The exposed stepwedge film should be processed and evaluated every day, as this ensures consistency in the results and allows for timely detection of any issues with the developer strength. Processing the stepwedge film less frequently could lead to inaccurate readings and potentially compromise the quality of the overall imaging process.
