| Title | Agreement State Report - Damaged Moisture Density Gauge |
| Event Description | The State provided the following information via facsimile:
At approximately 2 P.M., the licensee called the Department to report that one of their moisture density gauges (CPN model MC3, serial # M39099115) had been run over by a large truck at approximately 12:20 P.M. earlier in the day. This happened when the gauge user had his back turned from the gauge and he was standing approximately 15-20 feet from the gauge. The gauge source rod (Cs-137) was in the shielded position at the time. The housing was severely damaged and the source rod handle was broken off near the weld joint where the source rod attaches to the source capsule. Both the 8 mCi Cs-137 and the 50 mCi Am-241:Be sources remained in their shielded positions as determined by subsequent surveys. The incident happened at a Cal Trans job in Santa Paula, CA on Highway 150 at the 28.12 mile marker. The Cal Trans supervisor immediately shut the job down and sent all of the workers home. The area where the gauge was located was secured and roped off until the sources were verified to still be in the gauge. The gauge and the broken gauge handle was transported back to the Santa Clarita storage location where a representative from RHB performed the survey to verify that the sources were in the gauge and in their shielded positions. The gauge will be transported to local CPN service representative , Maurer Technical Services in Laguna Hills, where they will do leak tests on the gauge. |
