| Title | Lost Then Found Moisture / Density Gauge |
| Event Description | The following information was received via email:
On December 23, 2020, the Radiation Safety Officer (RSO) for ABI Engineering, Inc. contacted the California Department of Public Health - Radiologic Health Branch to report a moisture density gauge that was lost while transporting the gauge from the worksite in Orange, CA to the office. The gauge was locked in the transport case and placed in the vehicle, a pickup truck with a camper shell. During the short trip back to the office, the driver of another vehicle alerted the licensee's operator that the rear door of the camper shell was open. The licensee's operator then discovered that the gauge was missing, with one end of the chain used to secure the transport case loose. The licensee's operator backtracked to the jobsite in an attempt to find the gauge but did not locate it. The driver then notified the RSO and went to file a police report. Approximately 20-30 minutes after the RSO reported the incident to the Radiologic Health Branch, the RSO received a call from an individual who found the gauge. The gauge will be returned to the licensee. The gauge is a CPN International MC-3 (10 mCi Cs-137, 50 mCi Am-241:Be), S/N M39048766. The licensee's investigation into this event is ongoing and will be reviewed further by the California Department of Public Health. California 5010 Number: 122320 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.
