Which statement is true regarding the densitometric strips?

Densitometric strips are specifically designed to measure the optical density of radiographic films after exposure and processing. The true statement regarding them is that they should be exposed to sensitometric light only. This exposure allows for the assessment of the film's characteristic curve and provides insights into its sensitivity and contrast.

Using sensitometric light is crucial because it properly simulates the conditions under which the film will be used in actual radiographic procedures, ensuring accurate readings of the density. This controlled exposure is essential for evaluating the film’s performance without interference from factors such as X-ray scatter or other radiation variables.

This practice helps radiographers ensure that their films are consistently processed and interpreted reliably, which is critical for maintaining quality in radiographic imaging. Additionally, exposing the strips to X-rays would not provide the specific data needed for density measurement, making it less effective for the purpose they serve.
