Method for automatically mapping the radiation in a portion of a building and a robot vehicle

Abstract

A method is for automatically mapping the radiation in a portion of a building (7) using a robot vehicle (1). The portion of the building includes a plurality of building surfaces (9, 10). The method includes acquiring (1010) a 3D map (42) of a portion of a building (7). The 3D map (42) includes a plurality of segments (44), each representing a substantially flat building surface. The method further comprises applying (1020) to each segment (44) a plurality sectors forming a grid of sectors (46), each sector (46) having a border (48); physically marking, by the robot vehicle (1), the border (48) of each sector (46) with paint on the corresponding building surface (9, 10); and for one or more sectors (46), scanning, by the robot vehicle (1), with a radiation sensor (28) each sector (46), to measure the radioactive radiation within that sector.
