Overexposure to Radiographer


Print View Posted on: 19 November 2015

Event Date: 11 November 2015 Event Type: Radiation Source
Event Location: United States of America, Pecos, Texas/Nondestructive and Visual Inspection, INES Rating: 2 (Final)

After performing a radiograph, the radiographer believed he had cranked the source back inside the camera. However, when he went to retrieve the film, he noticed that his survey meter was reading off-scale, and then he noticed that his pocket dosimeter also read off-scale. The radiographer’s whole body dosimetry was sent for processing, which resulted in readings of 114.5 mSv (11.45 rem) deep dose equivalent and 114.9 mSv (11.49 rem) lens dose equivalent. The total effective dose equivalent accrued by the radiographer for the year was 125.8 mSv (12.58 rem). The radiographer has not shown any health effects from this event nor are any expected.
