ASNT Radiographic Testing Practice Test 2026 – Comprehensive All-in-One Guide for Exam Success!

When using a faster speed film in radiographic testing, the properties of the film affect the overall image resolution. Faster speed films are designed to be more sensitive to radiation, allowing them to produce images with less exposure time. However, this increased sensitivity often comes at the expense of detail.

The resolution, which refers to the ability of the film to distinguish fine details within the image, tends to be reduced with faster speed films. This reduction happens because the increased sensitivity leads to a broader range of light or radiation being captured, which can result in a loss of sharpness and finer details essential for accurate interpretation.

Thus, when replacing a slower speed film with a faster speed film, one generally observes a decrease in image resolution, making the correct conclusion that image resolution will be reduced. This understanding highlights the balance needed in choosing film types based on the required detail in the radiographic image, which is crucial for effective nondestructive testing.
