The invention teaches a cargo container craning apparatus comprising a crane; a trolley mounted flexibly on the crane; a spreader attached to the trolley by a suspension rope; a drive mechanism capable of moving the trolley; and a radiation detection device. The radiation detection device serves to detect the contents of the container while the container is being transferred and comprises a support frame; a detector frame; and a radiation detector being disposed on the detector frame; wherein the support frame is aligned with the spreader and is suspended by a suspension rope; and the detector frame is disposed on one side of the support frame. The radiation detection device allows ascertaining whether any hazardous radioactive materials are present in the container. The addition of a radiation body to the radiation detection device allows for radio-imaging of the container contents.
