AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE
The State of Oklahoma reported that on 7/22/10, at about 1530 CDT, a moisture density gauge at a construction site in Orienta, OK south of the intersection of Highway 60 and Highway 412, was run over by a tractor-trailer rig followed by 3 other vehicles. None of the drivers stopped.
The road was closed so that the area could be searched to locate the gauge. Initially the source rod (typically containing a Cesium-137 source) was not found after searching the scene.
The Oklahoma Department of Transportation (ODOT) was the licensee and owner of the gauge. The ODOT Radiation Safety Officer was contacted. At the time of this report the source rod was located and the RSO determined the source to be intact.
A major newspaper in the area posted information on the issue on their website.

AGREEMENT STATE REPORT - FIXED GAUGE SHUTTER FAILURE
The following information was received from the State of Pennsylvania via fax:
"Event location: Sharon Coatings
"Event Type: Shutter Failure
"Notifications: A call from the licensee was received July 23, 2010 @ 1410 by the Department of Environmental Protection explaining the event. This falls under 24 hour reporting under 10CFR31.2 and 30.50(b)(2).
"Event Description: It was discovered on July 22, 2010 at 15:30 that during a calibration of an ESC Resources (Model #NDS-200, Serial #20938), by the vendor the shutter was stuck open. Vendor was able to make repairs and restore shutter. The device is currently in use. Vendor checked all other gauges and found one other (Model #SH-5000, Serial #80209B), to be stuck as well. Vendor restored both to operational use.
"CAUSE OF THE EVENT: Equipment failure
"ACTIONS: Both devices have been repaired and restored back to operation"
PA Event Report ID No.: PA100017

NUCLEAR GAUGE DISLODGED FROM STEEL CASTER AND LATER RETRIEVED
"After completion of casting operations at the #1 Slab Caster, a trained worker proceeded to the mold strand area to remove the Berthold Co-60 rod source from the mold and place it in proper storage. The source is 3.97 mCi [Co-60] and is used to measure mold level of liquid steel. After all machinery and equipment was moved away from the mold so it could be accessed, the trained worker removed the plug to access the source for proper removal. Upon removing the plug, the trained worker noticed dirt and debris in the opening so he used compressed air to clean the area. The force of the compressed air into the source opening caused the source rod to lift out of the seated position and drop approximately 10 feet into the mold. The trained worker and a co-worker were able to retrieve the rod and place it back into its appropriate source holder. Investigation and exposure calculations indicated that neither employee was exposed above regulatory limits."
The licensee performed exposure calculations and estimated the trained radiation worker received a dose to the hands of 10.2 mRem. The assistant (not a trained radiation worker and not carrying dosimetry) received a calculated dose to the hands of 0.12 mRem.
