| Title | Agreement State Report - Damaged Moisture Density Gauge |
| Event Description | N.C. Radiation Protection Section was notified on 28 January 2008 by the RSO for ECS Carolinas, LLP Charlotte office that one of their portable moisture/density gauges (Humboldt Model 5001) was damaged at a construction site in Charlotte, NC. The gauge contains two sealed sources: (1) Cesium-137, 10 milliCuries (nominal) and (2) Americium-241:Beryllium, 50 milliCuries (nominal). Serial numbers for the gauge and the sources were not immediately available.
The RSO responded and performed confirmatory measurements on the device using a hand-held GM survey instrument. The gauge handle was detached from the source rod and index rod and the case has some minor damage. The index remained attached to the gauge and the source rod remained within the shield. The RSO's survey confirmed that the Cesium-137 source is still contained within the shield. The licensee also performed a survey of the area where the gauge was initially struck and readings were at background levels (approx. 0.05 mR/hr). The readings at one meter from the gauge were approx. 0.4 mR/hr (consistent with the TI [Transportation Index]) and at one foot were approx. 2-3 mR/hr. The licensee has been in contact with the manufacturer and has received instructions on packaging and returning the device to Humboldt Scientific (Raleigh, NC). The device has been transported back to the licensee's storage facility and will be returned to Humboldt's Raleigh facility later this week. North Carolina has assigned Event Report ID No. NC-08-03. |
