In this paper are presented some technical aspects from the decommissioning process of a Teletherapy machine model “Theratron Equinox” that contained category one Cobalt-60 radioactive source. This study includes some technical aspects of dismantling, security, transport and personal doses assessment during the dismantling procedure of teletherapy machine based on the Albanian Laws. During the dismantling process were used thermoluminescence dosimeters and Electronic Portable Dosimeters for personal doses received. The dismantled teletherapy head was transported securely to the National Radioactive Waste Storage Facility. This study highlights safety and security measures taken during the decommissioning process of Cobalt-60 sources while minimizing occupational exposure.
