Development of ionizing radiations dosimetry by plastic detectors and films of radiography

This work shows the development of an automatic and computerized system for detection and analysis of the ionizing radiation trace in solid detectors and one of the signals of this irradiation in radiography films with the main goal of improve the ionizing radiation detection methods. On the development of this method it was used a calibration source of 252Cf, which is a radionuclide with alpha decay and spontaneous fission and, by this reason, irradiates α and γ particles and nuclear fragments. Solid detectors of makrofol ware used for the nuclear fragments and radiography films ware used for the detection of α and γ particles. Those signals images reveled of the α and γ particles and of the nuclear fragments traces ware analysed on a microscopy and recorded on computers. The computer system developed allows to capture those images from the microscope as computer files, the identification of nuclear fragments traces and the α and γ particles signals and the separation of the objects of interest to do the counting and analysis of the size and the shape of those traces
