On 11/5/2008 at approximately 10:45 am, the licensee had a
Troxler moisture-density gauge (Model 3430, S/N 33839) on the ground in the "standardize" mode (sources shielded) when it was run over by heavy mechanical equipment. Licensee staff roped off the area around the
gauge and maintained surveillance of the
gauge until the
RSO and consultant arrived. Based on a radiation survey, there was no apparent loss of shielding integrity. Results of leak tests on the sealed sources are pending.
Gauge was transported back to the licensee's office for further evaluation and likely return to
Troxler.
Amount of activity: 8 mCi (Cs-137) and 40 mCi (Am-241)
Georgia Report Number: GA-2008-461
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than
IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as
moisture density gauges or thickness
gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
