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

Overdose to Nuclear Pharmacist

The licensee (PETNET Solutions) has confirmed an extremity dose of greater than 0.5 Sv (50 rem) to one of its nuclear pharmacists. Dosimetry results for a ring badge worn on the pharmacist’s right ring finger accumulated a total dose of 0.511 Sv (51.1 rem) for the year as of October 19, 2016. The pharmacist received the dose while working at the licensee's locations in Phoenix, Arizona, and Portland, Oregon. The pharmacist has been placed on work restrictions. The licensee expects to complete a root cause analysis within 2 weeks. NRC EN52350

Overexposure to Radiographer

The licensee radiographer's dosimetry report for July 2016 recorded a dose of 0.055 Sv (5.5 rem), bringing his total dose to 0.064 Sv (6.4 rem), which is above the statutory limit of 0.05 Sv annually (5 rem) for a radiation worker. The Radiation Safety Officer believes the radiographer may not have been properly distancing himself from the source while performing radiography in an enclosed area. NRC EN52199
