In the last week or two during an inventory check at a temporary job site storage building, at the University of
Pennsylvania, it was discovered that a
Troxler Moisture Density gauge, Model 3411B, serial number 9524, was missing. US Engineering Labs
RSO was notified by NRC Region 1 that their
gauge had been recovered by a Philadelphia Fire Department located in Northeast Philadelphia. The
gauge is stored at a Hazmat storage facility. The
RSO said he is going to meet with an NRC Region 1 Inspector and pick up the
gauge. The
gauge is fully padlocked and still in its case. It does not appear that the case containing the
Troxler Moisture
gauge had been opened.
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.
