Potential Overexposure of Members of the Public

A non-radiation worker who was working in the immediate vicinity of five fixed nuclear gauges used to monitor coal flow through coal chutes at a non-nuclear power plant was exposed to the radiation beam emitted from the fixed nuclear gauges. The exposure to the gauges occurred as he worked near each one in sequence. The licensee preliminarily subsequently determined that the worker likely received 6.5 mSv (650 mrem), which is in excess of the public dose limit of 1 mSv (100 mrem.) Additionally, it was determined that five other non-radiation workers may have received doses in the range of 1.4 mSv to 4 mSv (140 to 500 mrem). The U.S. Nuclear Regulatory Commission is currently conducting a special inspection of this event.
