A radiation incident involving detachment of a cobalt-60 industrial radiography source and its management.
A radiation incident took place inside an open-top radiography enclosure involving an Amertest-676 exposure device containing a cobalt-60 source of activity 2.15 TBq. The exposure device was being checked after receipt of a fresh source. The source assembly having been projected out could not be brought back into the exposure device. After thorough planning, the situation was brought under control by driving the disengaged source assembly into the exposure device. During the incident, the maximum individual whole body dose was 3.1 mSv.
