Title	Overexposure During Radiography
Event Description	A radiographer and his assistant were conducting a radiography exposure of a pipe weld. As the radiographer was picking up the crank handle to retract the source to the "safe shielded/locked" position, the radiographer was distracted when he heard someone yell "hey." The radiographer and his assistant investigated the sound on either side of the roped boundary. The radiographer left the survey meter back at the crank handle. Thinking the source was stowed, both approached the weld they were radiographing. They removed the source tube and collimator from the weld, and removed the film. The assistant walked back to the crank to place the film with the other exposed films and noticed the survey meter was pegged high. He immediately retracted the source to the "safe shielded/locked" position. Both men checked their pocket dosimeters and found them to be off scale. Dose estimate calculations indicate that the RSO may have received up to 5.5 Rem and the assistant may have received up to 2.5 Rem. The film badges have been shipped via overnight express shipping for immediate processing and report. Exposure Device: Amersham/Sentinel Model 660B S/N B-2790. Source: AEA Technology Iridium-192, model 424-9, S/N 21852, 37.5 Curies.
