This event took place in the Southmoor Subdivision, Phase 2, Eagle Mountain,
UT.
This event involved Troxler, model 3440, serial number 28420, containing 8 [millicuries] of Cs-137 and 40 mCi of Am-241:Be. The technician was testing sidewalk compaction ahead of the cement crew and was trying to keep ahead of the concrete truck. To do so, the technician would put the gauge in the back of his truck and drive about 200 feet along to the next test site. The gauge was not put in the transportation box nor was it secured. The technician drove off the asphalted road onto a 'roughed in' dirt road. When the truck hit the bump, the Troxler gauge slid or bounced out of the truck and hit the asphalt. The technician realized very quickly that the gauge was no longer in the truck and could see it approximately 200 feet behind the vehicle. Initially, the source rod remained in the safe shielded position, but the technician tried to lift the gauge by the handle and the source rod totally detached from the remaining portion of the gauge.
The Am-241:Be source was not damaged and remained in place.
