Speech Title: Lonizing Radiation Detection using CMOS Sensors


Nuclear technology is being promoted and applied worldwide but poses a certain threat to public safety, thus necessitating nuclear radiation detection. In addition to the use of dedicated instruments, the use of surveillance cameras with complementary metal oxide semiconductor (CMOS) sensors is a promising direction for nuclear radiation detection. We have developed several techniques to detect the nuclear radiation using CMOS sensors as follows: 1) we have developed the inter-frame difference algorithm and APP based on smartphone which can detect the radiation in real time; 2) we have developed another APP which can detect the radiation and the heart rate simultaneously; 3) we have developed the algorithm based on CNN network to identify the radiation blotches form the optical videos, which can be used in the surveillance camera to perform surveillance monitoring and radiation detection simultaneously. Our works provide an extremely low cost approach for radiation detection and monitoring. In this talk, we will describe details of the ideas, algorithms and verified experiments.
