The Fukushima Daiichi Nuclear Power Station (FDNPS) suffered a meltdown as a result of a large tsunami triggered by the Great East Japan Earthquake on March 11, 2011. Understanding the distribution of radioactive substances inside the FDNPS is essential to execute appropriate decommissioning tasks. In this paper, we propose method for visualizing three-dimensional (3D) images of radioactive substances as a point cloud data (PCD) and integrating these data into 3D environment models. To demonstrate the usefulness of the proposed methods, a Compton camera was first employed to capture 3D images of radiation sources. The resulting PCD were then integrated into a 3D environment model of a measurement area acquired using the 3D light detection and ranging (LiDAR). This allowed in successful construction of a map to visually recognize the positions of radiation sources.
