Storage Phosphorus Radiography
Phosphorus storage foil radiography stores X-ray images in a foil that is read out by laser. It combines the flexible format of films with the advantages of digital technology.
Physical-Chemical Mechanism of Action
X-ray radiation is projected onto a special Phosphorus storage foil. The Phosphorus absorbs the radiation and stores it latent. During readout by laser, the stored light is released and then digitized.
Metallurgical Relevance & Risks in Welding
This technique is especially helpful in welding practice because it provides detailed images of weld quality and microstructure. Incorrect settings or a defective foil can lead to inaccurate images, which affects quality assurance.
Workshop Practice & Action Instructions
Always use a clean and correctly calibrated Phosphorus storage foil. Make sure the laser readout process is optimally set. If image quality issues occur, check the foil and the device settings.
