Increase in the efficiency of radiographic inspection of welded joints for quality

The possibility of increasing the efficiency of radiographical inspection of metallic structures and pipelines welded joints for quality when mounting NPP equipment at the expense of a shorter exposure time is studied. The radiographic control has been conducted with X-ray RUP type instruments and ''Gammarid-25'' defectoscope. The exposure time is shown to be reduced when using active developers for processing radiograms. The sensitivity of radiographical images to X-ray and gamma-radiation increases when using D-82, D-72 active developers and ''roentgen-2'' standard developer for photochemical treatment
