Since the Fukushima Daiichi Nuclear Power Plant accident, various radiation imaging systems, including Compton cameras, have been developed. A fractal geometry-based detector (FRIE) has been developed as a detector that enables measurements in 360-degree directions, instead of the two-dimensional measurements of existing Compton cameras and pinhole-type cameras. In addition, by optimizing the inverse problem analysis method to match the characteristics of this detector, 3D radiation image reconstruction has been achieved. Here, as part of the series of presentations, we report the results of field tests in an environment using this detector system.
