Title	Lost Troxler Gauge
Event Description	The following information was provided by the New Jersey Department of Environmental Protection via email: During a state prompted inventory for license renewal, the licensee discovered the loss of a portable gauge. The last confirmed possession of the gauge was December 15, 2017, when it was marked in their logbook to be sent for maintenance. No manufacturers or service providers contacted have any record of the gauge past 2017. Gauge description: Troxler Electronic Labs. Inc. model 3411-B, serial number: 18670, containing sealed sources: Cs-137, 9 mCi (max), Am-241/Be, 44 mCi (max) New Jersey Incident Number: 506950 - INV250001 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.
