Abstract
When irradiated with X-ray radiation, photo-stimulated-phosphor (PSP) imaging plates (IP) charge up with a latent radiographic image. Such image is discharged, hence (partially) erased, on exposure to visible light. In this work, the effects of exposure to light are quantitatively investigated and reported, in order to provide proper guidelines for (a) handling radiographically exposed imaging plates prior to scanning, so as to prevent excessive fading of the latent image and loss of information due to ambient light, and (b) removing the remaining latent image prior to utilising the imaging plate for a further X-ray examination. Data are reported for three types of light and two types of photo-stimulable phosphor.
