No additional information regarding device or source is available at this time.</br>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 He stated that he turned the crank handle about 3/4 of a turn, at which time the source was retracted.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.</br>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.</br>NOTE: This report is being made as a precaution until the actual dose received by the radiographer is confirmed.</br>Ref: OH 2010-013</br> * * * UPDATE FROM STEPHEN JAMES TO PETE SNYDER AT 0950 ON 4/15/10 * * * </br>The following information was received via email:</br>1.
