Many old 60Co units are decommissioned because of weak activity as well as long treatment times required. However, the effectiveness of linear accelerators has greatly improved over recent years. It was a useful tool for treating head and neck cancers and superficial tumors during several decades. Introduction Teletherapy 60Co unit has a specific energy and is easy to maintain. The 60Co machine was smoothly dismantled and transported by trained workers and driver, using planned and controlled radiation protection, followed by ALARA (as low as reasonably achievable) rule.ġ. This study shows that the original lead head can be used as the source container of this 60Co unit but not as a long term storage option. The workers received doses of approximately 55 µSv during the whole process. This work pre-estimates the doses received to workers during the removing process. The personal doses measured during the process. This study describes the planning and removing process of the disused sources and, transports it into its head. The head containing the source was removed and put into approved package for transportation, after the source kept in safe position. Different radiotherapy facilities need to unload this 60Co unit after being disused. One of the widely used in Egypt is Alcyon CGR MeV. Teletherapy units containing 60Co source are used in Egypt and worldwide for treatment of cancer diseases.
