A recovery tool for recovering a solid element, in particular a radioactive material. The recovery tool includes a chassis, a capture head and at least one cup. The capture head is movable with respect to the chassis between a retracted position and a deployed position. In the retracted position, the capture head is accommodated within a chamber of the recovery tool. In the deployed position, the capture head is able to capture the solid element. The cup is movable with respect to the chassis between an open position and a closed position. In the open position, the cup allows the capture head to be deployed. In the closed position of the cup, the cup allows the solid element to be retained within the chamber with the capture head in the retracted position.
