Traditionally, the conventional analysis of continuous dynamic images in terms of the cineradiographic images lacks objective criterion so that the quality analysis and comparison of the continuous images can hardly be seen. Therefore, some attempt was made to qualify the data using the visual experiment, especially in this study, focusing on the discriminative ability for the contrast of the images in the cineradiographic images, i.e. signal detection ability in the complex of the noises. Through the series of this study, our observed results indicted that 1) the contrast of the image is affected by the observation time of the series of the cineradiographic images, 2) the critical and threshold point measurement which were derived from the relationship between the time and contrast supplies the possible objective qualification and comparison among the series of the cineradiographic images, and 3) viewing the continuous dynamic images is superior to observing one frame static image with respect to the discriminative ability of the contrast.

We intended to estimate low level radiation doses which were not detected by ordinary photographic densitometry. Minor radiation doses recorded as silver atoms of badge films, which were not detected with a photographic densitometer, were estimated by irradiating the silver atoms with thermal neutrons by KUR (Kyoto University Research Reactor). We have already reported "Low-Level Dosimetry based on Activation Analysis of Badge Film, Report 1 : Sensitiveness for ^<60Co> γ-rays". In this paper, possibilities were discussed about the application of the previous method to X-rays with energies between 35 to 150 kV in diagnostic use. Both the calculation and experiments were performed on the energy response of badge film in the energy range. Neutronactivation was performed on the X-ray exposed badge film at a thermal neutron flux of 10^9 neutrons/cm^2/sec for 2 minutes, then emitted gamma rays of ^<110>Ag, 658 keV, were measured with a NaI (T1) detector. The exposure vs ^<110>Ag activity curve was analyzed, and the minimum detectable amount was estimated. Following results were obtained : (1) the energy response of badge film was almost flat in the X-ray energy range from 35 to 150 kV, (2) the exposure vs ^<110>Ag activity curve was linear, (3) the minimum detectable amount of dose was less than 2.58 x 10^<-7> C/kg (l mR). These data suggest that detection of minor doses is possible with the film badges for personnel exposures in the X-ray diagnosis division of the radiology department.
