Loss of Radiation Source |
Refer to the event reported on 2009/09/07 on loss of a Neutron Source (Am-Be), after intensive investigation, the source was found and returned to the Atomic Energy Organization of Iran (AEOI) for respected QC and recertification.

Worker Overexposure |
The Licensee reported a potential overexposure based on a ring dosimetry report that indicated a dose between 119 and 40 mSv (11.9 and 4 rem). Licensee investigations indicated that a research technician is believed to have received between 0.5 to 4 Sv (50 to 400 rem) to his fingertips due to improper handling of bromine-76. The range of the 0.5 to 4 Sv dose estimate was based on interviews with the technician and the results of a Varskin computer calculation. There were no observable effects to the fingertips.

Contamination of workers during dismantling of alpha dry glove boxes |
During the second half of June and beginning of July 2001 the alpha dry glove boxes were dismantled in the Nuclear Research Institute Rez. The boxes were part of the facility for production of fire detectors of a Czech firm. Material from these boxes was contaminated by Am 241 and was after fragmentation put into casks used for storage of radwaste materials. During the performed operations the dust particles with Am 341 were released and were partially inhaled by the four workers performing fragmentation operations.

Plutonium uptake at Chalk River Facilities |
On May 26, 1999, four AECL employees entered a controlled radiological zone to perform work on a ventilation system. The work involved the removal of a component (baffle box) in a room in a building that contained a plutonium processing facility. The facility has been non-functional since 1957, and remained in a dormant state in preparation for decomissioning.
INES [N/A] |
Small fire in the research reactor LR-O building in Rez |
The research reactor LR-O in Rez was in shutdown because of a central heating reconstruction. On May 20, 1997 at 9.00 a.m. a small fire occurred in the reactor building. Isolations of pipes and cables burned in the central heat exchanger room, which is situated out of the radiological controlled area. The fire was caused by external workers and extinguished very quickly. No injuries occurred, no influence on nuclear safety was assessed. The event is reported because of a possible public interest.
