AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGN

The following is a summary of information received from the State of Colorado via E-mail:

The licensee is unable to locate a tritium exit sign with an activity of 7.5 Ci. The exit sign was determined to be missing.

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.
