On October 9, 2013 at approximately 1445 CDT, the Agency [Texas Department of State Health Services] received notice by phone that the licensee had lost a Troxler 3430 (sn 28350) moisture/density gauge near the Donna International Bridge near Donna, Texas. The sources contained within are an 8 mCi Cs-137 source (QSA Global X1218 sn 7502362) and a 40 mCi Am-241/Be source (QSA Global AX1 X.1 X.1/2 sn 47-25061). The gauge had been left on a tailgate out of its transport container when the truck left the temporary job site at approximately 0930 CDT.

Texas Report # I 9123
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.
