| Title | Missing Source |
| Event Description | The following information was received from the office of Alabama Radiation Control via email:
This report is connected to NMED item 140245, Nuclear Regulatory Commission Event Notification Number 50082 [Damaged Moisture Density Gauge, May 2, 2014], and Alabama Incident number 14-14. Alabama Radiation Control received an email from Troxler Electronic Laboratories on October 9, 2024. The licensee returned the gauge involved in this incident to Troxler in July of 2022. The device was retrieved for service this month. The Troxler representative reported that the cesium-137 source was not present at servicing. The americium-241/beryllium source was present and is being prepared for disposal. We are investigating with the licensee, transportation department contacts, and others. Model: CPN MC-3 Serial Number: M30129990 Activity: Nominal activity of 10 millicuries cesium-137 and 50 millicuries of americium-241/beryllium. 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.
