| ENS 44704 | 1 January 2003 06:00:00 | Agreement State | Agreement State - Texas - Report of Missing Gauge Containing 2 Curie Cesium-137 Source | The following was received from the Texas Department of State Health via e-mail: The gauge was discovered missing after Agency attempts to collect fees. Gauge registrant had provided self evaluation reports indicating they possessed the gauge and, after being contacted, admitted it was missing. The company had 2 gauges. The second was returned to Thermo Scientific. The missing gauge is reported to contain 1 curie of Cs-137. However, the manufacturer's information indicates it held 2 curies. A site investigation will be performed 12/09/08. The source information follows: Manufacturer: Thermo MeasureTech (Now Thermo Fisher Scientific), Model: 5203, Serial Number: B996, Isotope: Cs-137, Activity: 2 Ci, Source serial number: GK3804. The State of Texas is reporting this as their equivalent to NRC regulation 20.2201(a)(1)(i); reports of theft or loss of licensed materials > 1000 X App. C value. A representative of the State of Texas (Robert Free) was contacted and it was determined that the date that the gauge went missing or the circumstances are unknown at this time. The licensee is a dredging company that used the density gauge for underwater dredging activities associated with installing underwater pipelines. Texas report I-8587 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. | ||

Gauge registrant had provided self evaluation reports indicating they possessed the gauge and, after being contacted, admitted it was missing. The company had 2 gauges. The second was returned to Thermo Scientific. The missing gauge is reported to contain 1 curie of Cs-137. However, the manufacturer's information indicates it held 2 curies. A site investigation will be performed 12/09/08. A site investigation will be performed 12/09/08. The licensee continues to dispute inappropriate disposition of the gauge/source but cannot produce documentation to support the statement. The gauge is most likely fixed on a dredge in Florida but until definitive documentation is produced to support or show the whereabouts of the source, the Agency must formerly declare the source missing. A draft Notice of Violation is being developed to call the company in for enforcement. The source information follows: Manufacturer: Thermo MeasureTech (Now Thermo Fisher Scientific), Model: 5203, Serial Number: B996, Isotope: Cs-137, Activity: 2 Ci, Source serial number: GK3804 Texas Incident Report # I-8587 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.
