“…Imaging Plate is now used in various fields, because of its high sensitivity, good position resolution, large dynamic range and storage effect of latent images formed by incident particles(1)- (7). Imaging Plate stores the image in the form of F-centers and Eu3+ ions in the phosphor.…”

When the latent images formed by exposure with incident particles in the phosphor of Imaging Plate (IP) are irradiated with laser beam, photo-stimulated luminescence (PSL) is emitted and read through a photomultiplier. PSL intensity fades with increasing the elapsed time between the exposure and the PSL reading. When the IP is read successively, the PSL intensities decrease with the number of reading times. The tendency of the decreasing becomes gradual with increasing the elapsed time after exposure. The multiple successive reading method gives the means of the correction of the fading.

Two-dimensional measurement of radiation produced by natural irradiation of granitic rocks was performed by the use of an imaging plate, which is a storage film coated with photostimulated phosphor (BaFBr:Eu 2+ ). Radiation images of small volume specimens, such as thin sections were obtained with the imaging plate. Irradiation images of granitic rocks are inhomogeneous and the intensity of photostimulated luminescence per unit area, which is principally converted into the integrated dose, increases with the increasing potassium content in the rocks. The results of the present study indicate that the disintegration of 40 K is the dominant radiation source of granitic rocks. The imaging plate is a new research tool for the evaluation of the natural radioactive properties of geological materials and is applicable as a semi-quantitative two-dimensional dosimeter for natural radioactivity.
