• 論文の詳細を見る

•   A commercially available film scanner and image processing software "ImageJ" were satisfactorily used for automatic counting of track etched pits on a PADC detector irradiated with α-rays. The performance of the α-ray counting system with the film scanner was examined by the use of a goniometric α-ray irradiation equipment. Under the etching condition of the soakage in 6.25M NaOH solution at 70°C for 20 hours, the α-ray detection efficiency of the film scanner system was about 0.6 time as small as that of the general system with an optical microscope. It was confirmed that PADC detectors together with the film scanner system could be conveniently used for radon monitoring in atmosphere.
