Figure 4-20 (concluded). Examples of set up for remaining exposures.
Dosimeter chamber not set; however, it remains centered during all three exposures.
4-29. EVALUATION AND INTERPRETATION
a. Use the densitometer to measure the density at the reference marker.
b. Calculate the average exposure time and film density.
c. Compare individual recorded measurement with average values.
d. Record the information in the appropriate section of the form.
All three exposures should be the same or very close. If the AET system is
performing correctly, it should have reproducibility within five percent or
