Radiographic testing using storage Phosphorus screen systems
Radiographic testing with storage Phosphorus systems uses a photostimulable plate to store X-ray images and read them out digitally. This combines the advantages of conventional films with the efficiency of digital systems.
Physical-Chemical Working Principle
The storage plate reacts to X-ray radiation and stores the image information. A laser then reads this information from the plate and converts it into a digital format.
Metallurgical Relevance & Welding Risks
This testing method is especially useful for checking weld quality, as it reveals details like pores, cracks, or material changes. Improper handling of the plate can lead to image degradation or lost information.
Shop Practice & Procedures
Use the storage plate according to the manufacturer's protocol. Ensure the X-ray exposure is sufficient to get a clear image. Reading and storing the images should be done in a protected environment to avoid loss or damage.
