What is sensitometry used to check?

• A. Lead shielding effectiveness
• B. Checks correctness of developing parameters
• C. Film color balance
• D. Image receptor cleaning

Answer: (B)

Sensitometry measures how the film responds to light exposure and development, creating a graph that relates optical density to log exposure. This helps verify and monitor the processing parameters that shape image quality, especially the developing solution’s strength, temperature, and processing time. By examining the sensitometric curve, you can see if the processor is delivering the expected density and contrast, and you can detect changes in developer activity, temperature, or replenishment that would affect all images. It’s not about shielding effectiveness, film color balance, or cleaning; those are addressed by other QC tests.
