Industrial Radiographic Testing
How X-rays or gamma radiation can create images of internal features.
Safety boundary: this page is conceptual. It does not provide ionizing-radiation source handling, pressure-test procedures, hazardous chemical recipes, energized test instructions, machine settings or robot operation.
What this topic covers
How X-rays or gamma radiation can create images of internal features.
Core testing ideas
Radiography can reveal density and thickness differences through a component.
Geometry and material thickness affect image quality and detectability.
Ionizing radiation is hazardous and regulated; this site gives no source-handling or exposure instructions.
Measurement and method limits
Method capability depends on material, geometry, access, surface condition, calibration and operator competence.
Evidence and traceability
Indications require interpretation and comparison with approved acceptance requirements.
Using the result
Hazardous radiation, pressure, chemicals and machine-operation details are intentionally excluded.
