Abstract : A method for detecting and differentiating between containers of submerged junk and explosive-filled mines in demolition operations, comprising the steps of subjecting an unknown submerged container under surveillance to a gamma radiation source, traversing said submerged container with said source along a standard diagnostic path, detecting the changes in intensity of the radiation penetrating the submerged container, and recording the variations of intensity of said radiation penetrating the submerged container along said path to obtain a density signature of said submerged container.
