Beschreibung
Zusammenfassung:A handling tool (100) for securely handling a radioactive source (204) comprises a first securing device and a second securing device. The first securing device comprises a chamber (103), and an opening mechanism (105, 106) for opening the chamber (103). The opening mechanism opens the chamber when the chamber is brought in proximity with a source pocket that may contain a radioactive source (204), and the opening mechanism closes the chamber when the chamber is withdrawn from the source pocket (200). The second securing device comprises a gripping device (111, 112, 113, 114, 115, 116, 117) to grip and release a radioactive source (204), and a positioning mechanism (109, 110, 116) for positioning the gripping device in the source pocket (200) or inside the chamber (103) of the first securing device.
