The following information was provided by the California Department of Public Health via email:
"Ninyo and Moore, a geotechnical and environmental sciences firm reported the theft of a Troxler 3430 moisture density gauge No. 38218, containing a Cs-137 sealed source of 0.3 GBq (8 mCi) and Am-241 sealed source of 1.48 GBq (40 mCi). The theft occurred from a temporary job site in Visalia, CA, The locked 10' X 20' Conex job box had the locks cut off and the entire secured Knack box containing the Type A transport container and gauge was taken. Construction tools totaling approximately $12,000 were stolen. Visalia Police Department was notified and an officer took a theft report and is looking for video surveillance in the area.

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.

EN Revision Text: AGREEMENT STATE REPORT - DENSITY GAUGE SHUTTER FAILURE
The following information was provided by the Texas Department of State Health Services (Agency) via email:
"On February 23, 2022, the Agency was notified by the licensee's radiation safety officer (RSO) that one of his crews had a failure of a shutter device on a Thermo Fisher Model 5190 density gauge containing a 20 millicurie (original activity) cesium - 137 source. The RSO stated that the shutter is a lead sheet that slides in a channel in front of the source. The RSO stated that the channel the sheet of lead slides through was damaged and the lead sheet will not stay in place if the gauge is moved (jiggled). It cannot be locked in the shield (closed) position. The workers removed the gauge and the pipe it was installed on and placed them both in storage. The RSO stated they were going to contact the manufacturer to have the gauge repaired.
"No individual received any significant exposure from this event.
"Additional information will be provided as it is received in accordance with SA-300."
