The RSO stated the radiographers had completed an exposure and cranked the source back to the exposure device. The radiographer picked up their dose rate meter and observed the reading was 30 millirem an hour. The radiographer also observed that the locking mechanism had not tripped. The radiographer contacted the RSO. An individual qualified to perform source retrieval was sent to the scene. The radiographer did not approach the exposure device. The RSO stated the source retrieval person should reach the location in about an hour. Awaiting information from RSO. Update will be provided in accordance with SA-300.
Texas Report #: I-9232
THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL
Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate
brachytherapy and medium dose rate
brachytherapy. For additional information go to
