When [he] | | completed [the paperwork], he forgot the gauge was still sitting on the | | tailgate and drove off from the site. Approximately 300 feet down the | | access road to Loop 1604, he realized that he had not put his gauge away. | | To return to the site, he had to loop around several access roads to get | | back to the area. When he arrived back at the construction site, he could | | not locate the gauge. He called his company for assistance. The company | | sent other employees to search the entire area without result and then | | reported the gauge missing to both the Hollywood Park and San Antonio Police | | Departments. In a call to the Agency [Texas Department of Health] at | | approximately 7:30 a.m. on January 21, 2003, it was reported that they | | believe the gauge was found by another contractor who was also departing the | | site the night before. It is believed that the gauge was put into the back | | of [the other contractor's] truck. The gauge is a Troxler 3440, Serial | | Number 30433, with two sealed sources: Cs-137, 8 millicuries, Serial Number | | 750-4901: and Am-241/Be, 40 millicuries, Serial Number 47-27488. The | | Radiation Safety Officer called at 10:53 a.m. on January 21, 2003, saying | | the gauge was recovered at the construction site at 7:30 a.m. this morning | | (01/21/2003) from another contractor who had found it onsite. The | | construction superintendent, when notified at home on the evening on January | | 20, 2003, had located the contractor who found the gauge, and arranged for | | the pickup this morning. The RSO did not have full details but has the | | gauge back in his possession. The gauge was visually inspected for damage | | and no apparent damage was noted. Radiation levels were normal for the | | gauge. However, a leak test was performed on the gauge. Results are | | pending. Both Police Departments have been notified of the recovery. It is | | not known if the helicopter flight was performed during the hours of | | darkness. [Hollywood Park Police notified the FBI and arranged for a | | helicopter to search for the gauge with infrared equipment.]" | | | | The vehicle was a company pick-up truck.
