| Title | Agreement State Report - Troxler Gauge Damaged at a Job Site |
| Event Description | The following report was received via fax:
The Troxler gauge operator was in the process of calibrating the instrument for use at a temporary job site in Northborough, MA, and during this procedure the gauge was run over by a work vehicle. The operator of the gauge called and notified the RSO of McArdle Gannon Associates, our Agency [Massachusetts Radiation Control Program], and Troxler of the incident. The gauge operator provided the location of the incident, the model number of the Troxler Gauge (Model 3440), and indicated that the sources were located in the shielded gauge housing when struck by the work-vehicle. The Troxler Model 3440 contains two isotopes; Am-241, and Cs-137 with activities of 44 and 9 mCi, respectively. The operator also indicated that a safety perimeter was being established around the incident site using stakes and caution tape. An Agency [Massachusetts Radiation Control Program] inspector arrived at the site, and determined exposures were 63 mR/hr at contact, and approximately 0.4 mR/hr at a distance of 1 (one) meter. The device and vehicle which struck the device were surveyed for contamination, with all results indicating background levels. The inspector also identified that the Am-241 and Cs-137 sources were accounted for within the device. The licensee has contacted the gauge manufacturer and arrangements are underway for a leak test and safe transport of the gauge to the licensee's authorized storage location in Pembroke, MA, and eventual disposal of the gauge. The Agency [Massachusetts Radiation Control Program] investigation remains open. |
