Overexposure to Radiographer

During the performance of industrial radiography, the licensee radiographer approached the collimator without his survey meter. The radiographer positioned the collimator in preparation for an exposure shot without first retracting the 3.552 TBq (96 Ci) Se-75 source back inside the camera. Based on the dose assessment from the licensee, the radiographer received an overexposure of 1.76 Sv (176 rem) to each hand. At the time of the reporting of the event, there were no signs of skin reddening on the radiographer’s hands. The U.S. statutory limit for extremity doses is 0.5 Sv (50 rem).

Overexposure to Radiographer

As a result of a recent inspection by the State of Oklahoma, the licensee has learned that one of their radiographers received an annual whole body dose of 58.1 mSv (5.81 rem) for calendar year 2016. The overdose was accumulated over the course of the year. There were no unusual circumstances that caused the overdose. NRC EN52693

Stolen gamma densitometer

During the night of 13 to 14 April 2017, a gamma densitometer (Troxler 3440), which was used on a levelling work site, has been stolen from its storage location (Southern France).
It contains 2 radiation sources as follows :
1 Cesium 137 of 296 MBq activity
1 Americium/Beryllium 241 of 1480 MBq activity
Investigations are being conducted to find and recover the device.

Inadvertent damage of a Se-75 source

On December the 12th, 2016, a Se-75 source was inadvertently damaged during re-pair work on faulty radiography equipment. The work was performed in Düsseldorf region in North Rhine-Westphalia by a specialized company within a controlled area. The source contained about 1.3 Terabecquerel Se-75. The radioactive substance was released during the repair work and contaminated persons and zones within and out-side of the controlled area. Besides the two workers performing the repair work, other persons were also contaminated.
