Linear accelerator radiography

A description is given of the Risø lo MeV linear accelerator, which was used for radiography of steel (50 to 250 mm thick). Different X-ray film and intensifying screen combinations were tested and characteristic curves and exposure charts were computed. X-ray film speed and contrast were calculated.

Radiographic image contrast and quality were investigated and the best combination of X-ray film and screen was chosen. Conclusions were drawn about the possibility of using the Risø accelerator for industrial radiography.
