Overexposure to Radiation Worker

On April 12, 2004, the U.S. Nuclear Regulatory Commission received preliminary information that an event occurred on January 9, 2004, resulting in a dose exceeding the annual occupational dose limits of 5000 mrem (0.05 Sv). The elevated dose rates were due to a failure to retract a source to its locked fully shielded position after an exposure, and proximity to the camera while setting up for the next exposure. A radiographer received a reported dose of 9347 mrem (0.09347 Sv) due to failure to properly survey the industrial radiography camera. The employees were utilizing an Amersham camera model 660B. The source was a 37.2 curie (1376 Bq) source of Ir-192, model number 424-9.
