The licensee reported a missing [moisture/density]
gauge from its storage location at the Calvert Gateway construction site at Town Center Boulevard and Md Route 4 in Dunkirk,
MD. The following are the
gauge specifications:
Campbell Pacific Nuclear (
CPN) MC-3 Portaprobe Moisture/Density
gauge,
SE Gauge No. 15, S/N: M300405608, Radioactive Materials:
Cesium-137, sealed source, 8 millicuries; Americium-241:Be, sealed source, 40 millicuries. The Anne Arundel County Police was notified (Report No.05-737156).
Less than the quantity of a IAEA Category 3 source.
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.
For some of these sources, such as
moisture density gauges or thickness
gauges that are
IAEA 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.
