Abstract :
The dynamic range of X-ray detection with image plates is investigated. A dynamic range larger than 108 in X-ray dose is experimentally observed using the Fastscan detector, which allows a wide range of sensitivity settings. At X-ray doses lower than 0.1 Gy a proportionality between photo-stimulated luminescence (PSL) intensity and X-ray dose is found, while at higher doses the PSL intensity starts to saturate. This saturation effect can be attributed to the coloration of heavily X-rayed image-plates by radiation-induced F-centers.
