Study on HD cameras with CMOS sensor degradation upon ionizing radiation exposition

In this paper we have exposed 3 HD cameras with CMOS sensor in long time experiment at different doses and exposition time with γ radiation from 2 sources of ionizing radiation – cobalt 60 (Co60) and cesium 137 (Cs137) at room temperature imitating the working conditions of “hot cell” premises. All components of the used camera are without radiation reinforcement, excluding the lenses. During the experiment, we found degradation of the irradiated cameras. As the absorbed dose increases, the image becomes brighter. Furthermore, experimental results demonstrated decreasing in signal-noise ratio (SNR) with increasing the absorbed dose. We confirmed that the HD
industrial cameras can operate in ionizing radiation environment with moderate decrease of
