| Title | Radiography Camera Source Not Fully Retracted |
| Event Description | The following information was received via email:
Radiographer failed to fully retract Se-75 source into QSA Model 880 camera while on a job site in Stratton, Ohio. No additional information regarding device or source is available at this time. Radiographer did not 'bump check' the source after retraction to make sure that the source was locked in the camera. He stated that he was using a survey meter as he approached the camera, but it slipped from his hand during his approach and fell to the ground. He stated that he did not verify proper operation after picking up the meter. He was approaching the camera from the rear and stated that he had not observed any reading on the meter. As the radiographer disconnected the guide tube, he noted that the source cable was still sticking out of the camera with the source. He stated that he turned the crank handle about 3/4 of a turn, at which time the source was retracted. The radiographer stated that he could not hear his alarming rate meter due to loud noise in the power plant where the work was being done. The radiographers pocket dosimeter (0 - 200 Mr) was reported as having gone off-scale. The licensee has estimated a whole body exposure of 1.8 R and an extremity dose to the radiographer's hand of between 3 R and 20 R. The licensee has shipped the radiographer's dosimeter for rush processing and expects to have results late Monday (4/12/10) or Tuesday. ODH [Ohio Department of Health] will conduct an investigation. NOTE: This report is being made as a precaution until the actual dose received by the radiographer is confirmed. Ref: OH 2010-013
The following information was received via email: 1. Camera was a QSA Model 880 Delta, S/N D6162. 2. Source was a QSA Se-75 source, 73 Curies on 4/9/10, S/N 2739. 3. Extremity exposure was to right hand. 4. The radiographer's dosimeter was processed and indicated a whole body dose (shallow) dose of 0.563 Rem for April 2010, through April 9, 2010. This is approximately four times higher than the radiographer received in March 2010 (0.147 Rem). 5. ODH [Ohio Department of Health] will investigate the week of April 19 to recreate event and verify dose estimates and events leading to the exposure. NOTE: As of the current information, the exposure received by the radiographer would not require reporting of the event. Final determination will be made upon completion of investigation by ODH. Notified R3DO (Orth) and FSME (McIntosh).
