Course Description

Industrial radiography is a non-destructive testing method that uses either gamma rays from radioactive sources or X-rays from electrical generators to create images of the internal structure of welds, castings, pipes, and pressure vessels. It is widely used in pipeline construction, aerospace manufacturing, shipbuilding, and nuclear power plants to detect hidden cracks, porosity, or incomplete fusion without damaging the component. There are two main categories of installation: fixed installations, which are permanent shielded rooms with maze entrances and remote control consoles, and mobile or site radiography, where portable equipment is taken to the component. The primary radiation hazard in both cases is external exposure to the whole body or extremities, so careful design of barriers, distances, and warning systems is essential. A well-designed installation not only complies with dose limits but also improves operational efficiency by reducing delays and false alarms.

What you'll learn in this course?

• By the end of this course, learners will be able to:

• Identify key components and operational principles of industrial radiography equipment.

• Perform basic shielding calculations using transmission factors and dose rate limits.

• Design controlled and supervised areas according to IAEA and local regulations.

• Specify interlocks, warning devices, and emergency systems for a radiography installation.

• Evaluate a layout plan for radiation safety and operational efficiency.

• Apply risk assessment methods to prevent overexposures and accidental events.

• Industrial radiography uses gamma or X-radiation to inspect welds, castings, and structures for internal flaws.

• It is widely applied in pipeline construction, aerospace, pressure vessels, and nuclear facilities.

• Two main categories are fixed installations (shielded rooms) and mobile (site) radiography.

Prerequisites

• Basic engineering knowledge and familiarity with nuclear systems, radiation safety, and engineering units
