AGREEMENT STATE REPORT - STOLEN TROXLER MOISTURE/DENSITY GAUGE

The following is a summary received via email from the state of Colorado:

On August 26, 2019 at 11:13 MDT, the Colorado Department of Public Health and Environment was notified by Ninyo & Moore, that Troxler 3430 moisture density gauge with 9 mCi source of Cs-137 and 44 mCi source of Am/Be was stolen from Colorado School of Mines in Golden, Colorado. The Troxler gauge was last seen on August 23, 2019. Campus police were notified and they have put out a state wide notification informing state police of the missing gauge.

Event Report Number: CO 190016.

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.
