Event Report Forms (ERFs) are filed to the IAEA. Sometimes there are multiple event reports, updating the rating, the event description. Here you only see the latest event report

ERF description: On August 24, 2018, during industrial radiography using a sealed radiation source (Ir-192, 1.22 TBq), the radiation source became stuck inside the guide tube, making it impossible to retrieve. During the initial response, the remote control cable was incorrectly assembled in the opposite direction, but the worker did not notice this mistake. The worker believed that the source had been safely retrieved into a shielding container, but instead, the source was pushed outside the container and remained inside the guide tube. When the worker attempted to detach the guide tube from the shielding container, the source became exposed. The worker then physically handled the source capsule with bare hands, resulting in radiation exposure. At the time, the worker did not have a radiation detector, so the exact position of the source was unknown. The source was later safely retrieved by another worker. The worker’s hand equivalent dose was assessed as 960 mSv, which exceeds the dose limit.
