Event notification Exposure incident of a worker rated level 2 on the INES – CEA Grenoble
On 3rd September 2013, the French Alternative Energies and Atomic Energy Commission (CEA) and one of its outside contractors, D&S, notified ASN of an exposure incident of a worker from D&S.
The exposure occurred on 23rd August 2013 during low level waste and rubble sorting operation at the Laboratory of Activated Material Analysis (LAMA), under decommissioning.
Within the next few days, ASN will conduct inspections of D&S and CEA in order to determine the circumstances of the event, to check the operation conditions and to investigate the causes of this event.
The worker is subject to a specific medical monitoring.
Owing to exposure exceeding one of the regulatory dose limits for a worker, this event has been temporarily rated level 2 on the International Nuclear and Radiological Event Scale (INES), which comprises eight levels from 0 to 7.
