The State provided the following information via facsimile:
The Department received notification at 3:00 pm on 1/30/06, from the RSO at Kumar and Associates, Colorado License # 778-01, that one of their Troxler Model 3430 moisture/density gauges had been stolen from a construction site in Westminster, Colorado. Apparently the technician, who was using the gauge at the construction site, left it unattended for 5 minutes, and discovered it missing when he returned. Local police were notified and responded to the scene. The gauge was found, undamaged, in a field at the construction site a short time later. No public exposures are expected from this incident. The Department is investigating.
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.
