AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE

The State provided the following information via email:

"On Monday, September 10, 2007, the Minnesota Department of Health (MDH) was notified by American Engineering and Testing that a fire had destroyed a Troxler Model 3430 moisture density gauge. The fire occurred at a private residence, which was a farm, and spread to a pick-up truck that was parked beside the garage to that residence. The fire melted the plastic components of the gauge but did not effect the Cesium-137 source in the source rod or the Americium-241:Beryllium source that was in the lead shielding. Members of the Fire Department who responded to the fire were instructed to maintain a safe distance from the truck to avoid minimize radiation exposures.

"MDH completed radiation and contamination surveys of both sources. No contamination was detected and the radiation levels were as would be expected with the shielding intact. The sources were placed in containers filled with sand to provide shielding and removed to a secure permanent storage location. The RSO and the Corporate RSO will complete leak tests and arrange for the appropriate containers for shipment to the manufacturer.

"The gauge was a Troxler Model 3430, Serial Number 23279, which contained approximately 9 millicuries of Cesium-137 (Serial Number 75-5294) and 44 millicuries of Americium-241:Be (Serial Number 47-19161)."

Minnesota Report number: MN07005

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.

STOLEN TROXLER GAUGE

On the morning of 09/10/07 the licensee [DELETED] was getting ready to calibrate a Troxler Moisture Density Gauge (Model 3440). The gauge (s/n 22678) was in the back of the company truck on the calibration block. The employee left the truck for 3-5 minutes to use the restroom and when he returned the gauge was gone. The sources in the Troxler gauge are Am-241/Be (40 mCi), and Cs-137 (8 mCi). The employee contacted his supervisor, who in turn contacted the State police (Report # 52-44047). Within 90 minutes the gauge was found in a vacant lot about a mile from the job site. The gauge was checked and found undamaged with the sources in the safe position. No one saw who might have taken the gauge from the truck.

MEDICAL EVENT - PATIENT RECEIVED AN UNDERDOSE OF YTTRIUM-90

On Monday 9/10/07, the licensee was administering a 66 millicurie dose of Yttrium-90 microspheres to a patient for the treatment of liver cancer through a catheter. The patient only received a dose of 47 millicuries, a 27% underdose. The licensee is investigating the cause of the misadministration, but they believe the catheter used for the administration of the isotope failed or is leaking. The licensee believes there is no permanent functional damage to the patient. The physicians have been informed by the RSO that they need to notify the patient of the underdose and report that notification to the RSO. The treatment device is from MDS Nordion and a MDS Nordion company representative was on site during the administration of the isotope. The licensee intends to use the MDS Nordion representative for technical assistance in troubleshooting this problem once background radiation levels permit a closer inspection of the catheter.

A "Medical Event" may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
