INES 2: Incident

Impact on People and Environment:
  • Exposure of a member of the public in excess of 10 mSv.
  • Exposure of a worker in excess of the statutory annual limits.
Impact on Radiological Barriers and Control:
  • Radiation levels in an operating area of more than 50 mSv/h.
  • Significant contamination within the facility into an area not expected by design.
Impact on Defence-in-Depth:
  • Significant failures in safety ­provisions but with no actual ­consequences.
  • Found highly radioactive sealed orphan source, device or transport package with safety provisions intact.
  • Inadequate packaging of a highly radioactive sealed source.

Overexposure to Radiographer

A lead radiographer approached the end of the guide tube having assumed that the source had already been retracted into the shielded camera. After approximately 90 seconds the assistant radiographer entered the area. The assistant radiographer’s alarming rate meter and survey meter indicated the presence of radiation and the two individuals left the area. The lead radiographer was wearing a whole body dosimetry badge which was sent for emergency processing. The dosimeter was measured by the vendor at 8.36 mSv (836 mrem).

Overexposure of radiographers

During radiographic operations performed by two radiographers the guide tube was squashed so the Ir-192 source could not be retracted to the gamma projector. Operations were being performed at 6 m height. The operator tried to correct this situation using a plier to strainghten out the guide tube but unsuccesfully . Then the guide tube was cut and the Ir-192 source was recovered using tongs and shieldings. The workers took personnel dosimeters, alarm dosimeters and detectors but radiation protection officer was absent.

Interventional Radiology - Exceeding of the maximum regulatory annual effective dose

On 30th May 2013, ASN was informed that the passive dosimeter results for a radiation therapy technician in Saint-Eloi hospital of the Montpellier CHRU had integrated over the last quarter of 2012 an effective dose of 32 mSv. This result is higher than the regulation annual limit set at 20 millisieverts.

The hospital initially assumed malfunctioning or incorrect use of the dosimeter. Upon receipt of the incident notification, ASN then asked the hospital to investigate further and to report on the occupational physician’s conclusions.

Internal contamination of radiation workers during radioactive waste management

On 2nd December 2013 three radiation workers opened 4 metal drums filled with compacted radioactive wastes containing 241-Am. The purpose of opening the drums was the waste sorting and compaction of waste at higher pressure. During operation contamination occurred. The control measurements found the worker’s hands, clothing, and the waste compactor room contaminated.

Exposure of workers performing industrial radiography

In October 2013, four workers were exposed performing industrial radiography at a building construction site of a thermo power plant in Slovenia. The dosimetry service reported the received doses of 27.5 mSv, 19.18 mSv, 2.62 mSv and 1.86 mSv in one month period. The received doses of all four workers exceeded a monthly dose constraint of 1.6 mSv. The total received annual doses of two workers were 32.25 mSv and 20.52 mSv exceeding the statutory annual dose limit for occupationally exposed workers of 20 mSv.

Overexposure to Radiopharmacy Worker

A radiopharmacy worker has received a cumulative annual extremity dose of 559 mSv (55.9 rem) to the right hand, and 543 mSv (54.3 rem) to the left hand, which exceeds the statutory dose limit of 500 mSv (50 rem) to the extremities. The worker has been removed from job duties involving radiation exposure. NRC EN49493.

Stolen of a radioactive source

According to the report of Tabriz University Radiation Protection Officer (RPO), a Pu-Be Neutron source was stolen from storage location. National Radiation Protection Department (NRPD) immediately involved in the subject and informed responsible organizations in National and Provincial levels. The source was registered with the activity of 130 GBq (3.5 Ci).

Exposure of a worker in excess of statutory annual dose limits

On 3rd September 2013, the French Alternative Energies and Atomic Energy Commission (CEA) notified ASN of an exposure incident of a worker from one of its outside contractors.

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.

ASN has conducted an inspection of CEA on 6th September 2013 in order to determine the circumstances of the event, to check the operation conditions and to investigate the causes of this event. Corrective actions have been required by ASN.

Deficiency in the safety evaluation of the primary reactor drain line

On 19 February 2013 NRG reports the discovery of a deficiency in the safety evaluation of the primary reactor drain line of the High Flux Reactor (HFR). It was found that the possible failure of the primary drain line of the reactor was not considered in this safety analysis.

Overexposure to Radiopharmacy Worker

A radiopharmacy worker received an overdose to both hands. The worker received 576 mSv (57.6) rem to the left finger and 527 mSv (52.7) rem to the right finger. The licensee is investigating to determine the root cause and the timeframe of the overdose. NRC EN49402.
