Radioactive substance distribution map creating system and radioactive material distribution map creating method

摘要

The system for creating a radioactive material distribution map according to the present invention is provided with a radiation detector, a position measurement instrument, and a device for creating a radioactive material distribution map. The radiation detector is mounted to a movable body, and measures a radioactive material. The position measurement instrument measures the position of the movable body. The device for creating a radioactive material distribution map acquires measurement data including the results of measurement by the radiation detector and position information of the movable body measured by the position measurement instrument. The device for creating a radioactive material distribution map creates a distribution map of radioactive material using measurement data at a plurality of positions obtained in conjunction with movement by the movable body.
