Overexposure of a worker

On the 28th of January 2015, during an inspection of nuclear materials, a radiation worker accompanying the inspectors entered a hot cell containing a source of radiation. 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 present at the scene probably did not exceed 1 mSv (dose 0.7 mSv measured with personal electronic dosimeter, personal thermoluminescent dosimeters to be read). The Regulatory Body (PAA) was notified of the event on the 30th of January 2015. The event is being subject to further investigation.
