Abstract
Floating radioluminography using an imaging plate can be sufficiently applied to the monitoring of the surface contamination on rough surface materials at a radioisotope facility. This technique is superior to the smear method which has been used to estimate the contamination of low energy β-ray emitters, because the fixed contamination and the contamination on the coarse surface materials have been difficult to be wiped out on a smear paper. The radiation detection efficiency of the imaging plate is as high as the liquid scintillation technique, when the plate is exposed with the sample in a vacuum chamber. In this study, the technique has been tested to the surface monitoring of a liquid-waste concrete cistern, and the sort of contaminant radioisotope was estimated by inserting a plastic film or an aluminum plate between the imaging plate and the sample.
