DISPOSITIF DE CARTOGRAPHIE DE SOURCES DE RAYONNEMENT

摘要

The invention concerns an apparatus for accurately locating radioactive or other radiation sources in surroundings which may have been previously unknown, comprising a pair of visual cameras (7) oriented in such directions that they have a common visual field, and an intermediate camera (6) sensitive to the radiation to be measured. The visual cameras enable the positioning of the details of the surroundings by triangulation method, and another triangulation is carried out to know the position of the sources after displacing the apparatus. Photographic surveying software is used for easily performing these operations.
