COLORADO AGREEMENT STATE REPORT - MISSING TRITIUM EXIT SIGNS

The following information was summarized from the information received from the state of Colorado via email:

In April 2018, the Colorado Department of Corrections - Fremont Facility identified that a tritium exit sign was missing. On 5/9/19, Fremont determined that the sign was lost. The exit sign contained 11.47 Ci of tritium.

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.
