The Nuclear and Radiation Safety Centre (NRSC) has successfully carried out the safe removal, transportation, and long-term storage of a disused high-activity cobalt-60 (Co-60) teletherapy source from the National Centre for Oncology named after V. A. Fanarjyan. NRSC specialists led the operation, ensuring comprehensive planning and coordination, radiation safety oversight, regulatory compliance, and full documentation throughout all phases of the process. The activity was implemented within the framework of international cooperation aimed at reducing radiological risks and strengthening the secure management of high-activity radioactive sources. The disused teletherapy head was safely dismantled, handled, securely packaged, and transported under enhanced physical protection measures to the facilities of “Radioactive Waste Management” CJSC, where it was placed into long-term storage. Radiation monitoring conducted before, during, and after the operation confirmed the absence of radiological contamination and demonstrated that occupational exposure levels remained well below established regulatory limits. The operation was carried out through close coordination among the Nuclear and Radiation Safety Centre, the Armenian Nuclear Regulatory Authority (ANRA), “Radioactive Waste Management” CJSC, the Ministry of Internal Affairs of the Republic of Armenia, and partners from the U.S. Department of Energy’s Office of Radiological Security. This successful operation highlights NRSC’s central role in ensuring nuclear and radiological safety in Armenia and contributes to the mitigation of potential radiological hazards through the safe and secure management of radioactive sources.
