Paper Abstract

Application of the fast-acting digital computers and the technical means of signals treatment allowed to spread the possibilities and the resolution of activation autoradiography. Analysis of autoradiographic features is connected with the elucidation of the optical distribution of the exposed and treated photoemulsion used as of detector of the secondary beta irradiation. In this report the possibilities of the digital image processing by the autoradiographic investigations of impurity and component distributions in the granat crystal are shown. Identification of radionuclides and the qualitative evaluation of their contents wee conducted by gamma-spectrum of specimens irradiated by neutrons. The treatment of autoradiograms was conducted with the help of the dialogue system having matrix in 512 by 512 elements. For the interpretation of the experimental data clustering analysis methodology was used. Classification of zones on the minimum of the square mistake was conducted according to the data of histograms of the optical densities of the studying autoradiograms. It was proposed algorithm of digital treatment for reconstruction of autoradiographic features. At a minimal contrast the resolution of the method has been enhanced on degree by adaptation of methods of digital image processing to suppress background activity.
