Radiographic Sensitivity in Industrial Radiographic Testing With X-Ray Films

Radiographic Testing (RT) is widely used in industries, at airport for security checks, medical applications etc. to detect anomalies in materials and human bodies. Radiographic Testing is the common NDT methods used in the construction and fabrication industries for the oil & gas sectors using welding, gas/liquid transmission pipelines, casting foundries, and condition monitoring in existing oil & gas refineries and facilities. This paper will discuss radiographic testing sensitivity using industrial X-ray films mainly on welds and castings. No in-depth discussion in related science and physics, merely the perspective of an industrial radiographer based on his experience.
