On the 28th of January 2015, during an inspection of nuclear materials, a radiation worker accompanying the inspectors entered a hot cell containing Ir-192 radioactive sources with total activity of 33.3 TBq. Worker remained inside the cell for about 1 minute. Worker’s personal dosimeter recorded an effective dose of 31 mSv which exceeds the annual statutory dose limit for radiation workers (20mSv). Doses received by the 3 inspectors (considered radiation workers) present at the scene were assessed as 1 mSv, 4 mSv and 8 mSv based on personal dosimetry. The Regulatory Body (PAA) has been notified of the event on the 30th of January 2015. A commission investigating the event issued recommendations to introduce additional safety features and training on safety culture.
