California via email:
On November 13, 2014, at approximately 0648 [PST], the RSO of Heider Engineering Services, Inc., RML #6463-36, contacted Cal OES [California Office of Emergency Services] concerning the moisture/density gauge, Troxler, Model 3430, serial number 63801 (Cs-137, 0.3 GBq, Am-241, 1.50 GBq) that had been stolen from a transport vehicle in front of a private residence at 140 North Shasta Way, Upland, CA 91786, between the evening of November 12, 2014 and approximately 0600 [PST] November 13, 2014 when the Authorized User left his home to go to the worksite. The Authorized User has contacted Local Law Enforcement officials in Upland, CA to request an investigation of the private residence where the Troxler radioactive gauge was taken and to take the report of the authorized user that was in possession of the gauge prior to the theft. A copy of the theft report will be sent to RHB Brea [California Radiological Health Branch -Brea] as part of this report. The RSO will utilize local papers to attempt to retrieve the stolen gauge as well as notifying local servicing vendors of radioactive gauges to be alert of the serial number of the stolen gauge in case it turns up for any of their services.
The investigation will continue to determine if the radioactive gauge can be recovered in a reasonable time frame. This is being reported to the NRC Operations Center as a 24-hour report under 10CFR30.50(b)(2) since the radioactive gauge has been stolen and it cannot be determined what condition the sources are currently in.
CA 5010 NUMBER 111314
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.
