The State provided the following information via facsimile:
A notification was made by the RSO on August 16, 2005, concerning a portable moisture density gauge that was run over at the Menasha coal plant, a temporary job site. The approximate time of the incident was 2:30 pm. The gauge was a Troxler 3440 containing 10 milliCuries of Cs-137 and 50 milliCuries of Am-241. The RSO reported that the radiation readings were verified as normal by comparing the reading at 1 meter to the Transportation Index. Visual observation confirmed that the source rod is in the normal position and the shielding is intact. Other individuals on the job site including the truck driver that ran over the gauge were surveyed. The area where the gauge was damaged was surveyed after the gauge was moved a few feet away and no radiation readings above background were noted. The gauge was transported back to the licensee's facility in Neenah [WI]. DHFS staff were dispatched to confirm that there was no contamination on August 17, 2005. The licensee has taken a wipe smear and is sending it to Troxler for counting. The gauge is locked in the transport case and has been placed in storage.
