On May 14, 2019, at 1324 EDT the Radiation Safety Officer (
RSO) was contacted by the Operation Manager and informed that a source located at a site in Muskegon MI could not be returned to the shielded position by the normal means. The technicians verified the boundary to ensure no unplanned exposure. The
RSO called the site technician and went through the source retrieval procedure. The source was a
SPEC model 150 camera with 89 Ci
Ir-192 source. The
RSO went to the site and was able to determine the location of the source and put temporary shielding on it. The
RSO determined the source tubing was crimped and was able to straighten the tube. The source was retracted into the camera and locked by 1550 EDT. The crimped tubing was replaced with new tubing. The device was tested satisfactorily.
There were no over exposures. The doses received during the radiography and retrieval process were:
RSO 28 mR, Radiography 23 mR, and Assistant Radiography3 mR.
