| Title | Damaged Troxler Moisture Density Gauge |
| Event Description | The gauge operator finished with a density reading and left the Troxler device at the measurement area when he was storing his tools in his truck. When he was returning to the measurement area, an end-loader drove over the Troxler, destroying the hand operating pad. At the time of the accident, the source was retracted into the shield. Immediately after the accident, the operator covered the gauge with shielding and established a boundary zone. No overexposures or contaminations are expected as the sources were retracted into the shielded position.
The Troxler is a model 3430 which contains 40 mCi of Am-241 and 8 mCi of Cs-137. The licensee is conferring with Troxler to determine whether the gauge will be repaired or returned for disposal. 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.
