A method for underwater packaging of radioactive materials includes creating a vacuum in a cavity of a cleaning device to automatically cause a portion of the cleaning device to move upward to actuate the cleaning device from an open position to a closed position; mounting the cleaning device inside a safe containment area of a transportation and/or storage device; placing the transportation and/or storage device in a pool after filling the safe containment area with water; loading a radioactive material into the safe containment area; closing the transportation and/or storage device using at least one cover; extracting the transportation and/or storage device from the pool; draining the water inside the safe containment area; and creating a pressure differential in the safe containment area to dry the safe containment area, wherein the pressure differential causes the cleaning device to automatically actuate from the closed position to the open position.

Gamma-camera utilizing the interaction depth in a detector

A method for reconstructing an image of a source (S) of photons from interactions of photons emitted by this source with a detector () of a gamma-camera, positioned behind a collimator (), the method including associating with each photon interaction with the detector, a piece of information relating to the depth in the detector, of this interaction, and reconstructing an image of the source (S) of photons from said depth information in the detector.
