INDUSTREX Film Processing and Exposure Instructions
To achieve optimal radiographic image quality with INDUSTREX films, it is important to follow recommended processing conditions for development time and temperature and then determine proper exposure (dose) for the selected film type and object being examined.

Follow Recommended Processing Conditions – Will deliver the film’s designed speed and contrast and ensure that performance matches requirements for system class per EN ISO and ASTM E. It is important to set processing conditions first before establishing exposure.

Determine Proper Exposure (Dose) – Sufficient dose is essential to achieving high-quality radiographs. During exposure, image detail is recorded in the film’s emulsion layer. Underexposure will limit image quality, increase grain (noise) and reduce signal to noise ratio.
