The following information was received from the State of Nevada via email:
At approximately 1350 PDT, the RSO/CEO for IQC Southwest LLC, 00-11-0745-01 notified the Nevada Radiation Control Program (NRCP) that a Portable Nuclear Gauge (PNG) had been stolen from a work site located near the intersection of Sierra Vista and Paradise Road working off of Paradise Road in Las Vegas, Nevada. In addition, Las Vegas Metro Police Department was on scene and taking a report during the Radiation Safety Officers (RSO) notification call to the NRCP.
The RSO stated that they had video of the theft as it occurred. An unknown (possibly transient) individual walked through the work site, picked up the gauge and walked off, appearing to hide the gauge with his body while the Authorized User (AU) was getting material from his vehicle. The source rod was not locked when the gauge was taken.
The gauge was a Troxler model 4640-B with a 9 mCi Cs-137 source.
An incident inspection will be performed June 16, 2022 by the NRCP.
Nevada Item Number: NV220006
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.
