On June 22, 2009, the licensee placed an INC IR-100 radiography camera on the tailgate of his work truck. The radiography camera contained a 54 curie
Ir-192 source. The camera was not secured on the truck and the tailgate remained in the open position. When he arrived at the job site 25 minutes later he realized the camera had fallen off the truck. In order to look for the camera, the licensee proceeded back along the same route he had taken to the work site. The licensee noticed a police vehicle travelling on the same remote rural road. He stopped the police vehicle for assistance and discovered that the police officer had coincidentally just recovered the camera from a passerby. A passerby had found the camera on the road and contacted the police. The camera was not damaged. There was no personal exposure as a result of this event. The camera was out of the licensee's possession for approximately one hour.
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.
