Abstract
A panel for radiation detection having a plurality of sensors arrayed thereon. Each sensor includes a charge storage capacitor, a radiation sensitive layer over the charge storage capacitor and a dielectric layer over the radiation sensitive layer. The dielectric layer has an adjusted resistivity resulting in a time constant &tgr;=&rgr;&kgr;&egr;,between 0.050 and 20 seconds, wherein &kgr; is the dielectric constant of the dielectric layer, and &egr;,is the permitivity of free space. The radiation detection layer is a photoconductor, and the dielectric layer is, preferably, a linear segmented polyurethane.
