Course overview

Radiographic Testing (RT) is a cornerstone volumetric examination method utilizing ionizing radiation (X-rays and Gamma rays) to penetrate components and capture internal structures onto radiographic film or digital media. This course covers the nature and properties of radiation, X-ray generation, radioisotope handling (Iridium-192, Cobalt-60, Selenium-75), exposure geometry, darkroom processing, and radiation safety in accordance with SNT-TC-1A (2024). Candidates gain a complete understanding of radiographic techniques required for evaluating welds, castings, and structural assemblies. Qualification Levels Offered • Level I: Sets up equipment, handles film/screens, performs source alignment, performs exposures, processes films in darkrooms, and records inspection data under qualified supervision. • Level II: Selects radiographic techniques, calculates exposure parameters, verifies image quality (density and IQI sensitivity), evaluates radiographs against codes, and manages reporting.
