INES 4: Accident with local consequences

Impact on People and the Environment:

  • Minor release of radioactive material unlikely to result in implementation of planned countermeasures other than local food controls.
  • At least one death from radiation.
Impact on Radiological Barriers and Control:
  • Fuel melt or damage to fuel ¬≠ resulting in more than 0.1% release of core inventory.
  • Release of significant quantities of radioactive material within an installation with a high ¬≠probability of significant public exposure.

Overexposure of workers at irradiation facility - follow up

History

The gamma-irradiation facility (GIF), located in the town of Stamboliyski, was put into operation in 1980, charged with 49 sealed Co-60 sources with a total activity of 426 TBq. The GIF was owned by the Agricultural Academy and had been used for the irradiation of food and agricultural products, as well as for scientific experiments.

From 1997 till 2005 the GIF has not been used for its intended purpose and the sources were temporarily stored in the facility. In 2005, the sources were transferred for long-term storage to the Novi Han RAW Repository.

Discovery of radioactive materials in scrap shops and acute exposure of scrap dealer

On April 07, 2010, AERB received a report from a hospital in New Delhi about a patient, a scrap metal dealer with suspected radiation-induced symptoms. It was also informed that the patient is a scrap metal dealer and has a shop in Mayapuri New Delhi. Two AERB officers were promptly sent to the site who confirmed the presence of radioactive material in the scrap shop of the dealer. Their survey also indicated presence of radioactive material in two other shops in the neighbourhood.

Overexposure of employee in irradiation facility

Fleurus, Belgium is the site of a Sterigenics irradiation sterilization facility, performing principally medical device sterilization. The facility uses gamma radiation emitted from sealed cobalt 60 isotope source. The cobalt 60 source is strictly contained in a thick concrete containment vessel.
When not in operation, this source is stored in a water pool. A secured hydraulic system allows taking the source out of this pool in order to irradiate the products put in the cell. Safety locks prevent the system to take the source out of the pool when the door of the cell is open.

Lost source causing a radiological accident at Meet Halfa, Egypt

On Monday, 26 of June 2000 the authorities in Egypt were faced with a radiological accident in Meet Halfa, a village of El-Qualuobia Governorate, 20 km from Cairo. The accident resulting from a lost Ir-192, 40 Ci source found its way to one of the village houses. The accident resulted in two deaths and other two severely affected. The team from the Atomic Energy Authority and Ministry of Defence succeeded in locating the source and the source was handled remotely and sent to the special storage area of the Atomic Energy Authority.
