STOLEN SOIL MOISTURE DENSITY GAUGE

The following information was received via e-mail.

The theft occurred at a temporary job site. The shipping container for the moisture density gauge was found to have the hasp pried off and the case and gauge stolen. The gauge was last seen at close of business on September 17, 2004, and discovered stolen on September 20, 2004. The keys were not taken. The police have been notified. The owner is considering offering a reward. The State of Florida is investigating.

The moisture density gauge was a Troxler Model 3440 (serial #25279).
Source activity is listed at 8 millicuries Cesium-137 and 40 millicuries Americium-241.

The Florida Bureau of Radiation Control and the State Warning Point were notified.

AGREEMENT STATE REPORT OF THEFT OF FOUR MOISTURE DENSITY GAUGES

The following information was provided by the State of California Department of Health Services via e-mail:

"Four nuclear moisture density gauges were stolen from a locked construction trailer near Simi Valley (Ventura County, CA) over the weekend of 9/18-19/04. In addition to the gauges, the thieves stole other equipment in the trailer belonging to the licensee (Construction Testing and Engineering) as well as construction equipment from a number of other contractor trailers at the construction site. Two of the nuclear gauges were Campbell Pacific Nuclear model MC3 (serial numbers # M390104780 and # M300105431), one was a Troxler model 3440 (serial # T34417651), and the fourth was a Troxler model 3411B (serial # T3414200). Each gauge contained small quantities of the radioactive materials cesium-137 and americium-241. While it is possible to utilize radioactive materials from a large number of such gauges to make a terrorist radioactive dispersion device (RDD), this theft does not appear to have targeted the nuclear gauges, but rather to have included the nuclear gauges in a theft motivated by the resale potential of the general construction materials that were taken. The thefts are being investigated by the Simi Valley police, who reported that there have been a number of such thefts of construction equipment that have occurred in the area, and it is possible that the equipment is resold in Mexico.

"DHS/RHB [Department of Health Services Radiological Health Branch] inspected this facility within the last few weeks, and did not identify any significant security issues related to the storage of the nuclear gauges at this site. The theft was reported to the federal government (Nuclear Regulatory Commission), who reviews such reports for possible national trends. Because of the possibility that the stolen materials may be resold in Mexico, the U.S. Nuclear Regulatory Commission (NRC) was requested to notify Mexican radiological authorities of the theft."

AGREEMENT STATE REPORT OF DAMAGE TO SOIL MOISTURE DENSITY GAUGE

The following information was provided to the NRC from the Florida Bureau of Radiation Control via e-mail.

A Troxler soil moisture density gauge (Model #3411-B; Serial #8598) was damaged when it was run over by a front end loader. The source rod was broken off and the cesium source was detached from the rod. Investigators searched and recovered the source. The gauge and source will be sent to Troxler for repair. No further action will be taken on this incident.

The Troxler source strength is 8 millicuries Cesium-137 and 40 millicuries Americium/Beryllium.

There were no personnel exposures.

TROXLER MOISTURE DENSITY GAUGE RUN OVER BY HEAVY EQUIPMENT.


The Radiation Safety Officer for Schnabel Engineering, Inc. located in Richmond, Virginia reported the following information.

Schnabel Engineering, Inc. had employees working at Norfolk Shipyard International Terminal when one of their Troxler Moisture Density Gauges was run over by heavy equipment. The gauge was in its secured position when it was run over. The source rod was slightly bent and the casing around the gauge was slightly cracked. The source was still inside the gauge when it was run over. Highest survey reading taken of the damaged gauge was 9 millirem per hour on contact. Troxler will be notified of this event and the damaged gauged will be sent back to Troxler.

Information of the gauge:

Model Number; Troxler 3430, 8 millicuries of Cesium-137 and 40 millicuries of Am-241/Be.

Serial number of the gauge is 31970.

Cesium-137 source serial number is 750-7028

Am-241 source serial number is 47-5674.
