On July 14, 2010, Saint-Gobain Performance Plastics contacted the New Hampshire Department of Health and Human Services and provided notification that an inventory had been completed and three thickness gauges were discovered missing. Saint-Gobain is still trying to locate the gauges.
Saint-Gobain is located at 701 Daniel Webster Highway, Merrimack, New Hampshire and possesses the radioactive gauges under a general license. The company is not a specific licensee.
The following missing Beta gauges were supplied by NDC: Sensor serial number 3195, equipment number 103 (7441 LX), source assembly date of 11/27/1992, 150 mCi of AM-241; sensor serial number 3108, equipment number 103 (4414 LX), source assembly date of 11/6/1991, 150 mCi of Am-241; sensor serial number 2271, equipment number 102 (1473 LX), source assembly date of 2/26/1990, 150 mCi of Am-241.

R1DO (Conte) notified. ILTAB (Hahn) and FSME Event Resources informed via e-mail.
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.
