The following was received by the State of
Colorado, Department of Public Health and Environment (CDPHE) via email:
The Waste Water Treatment Plant at the City of Lamar was in construction during the time period the tritium exit sign was ordered by the contractor on the project. An intermediary electrician was brought in to help with the installation of the exit signs. Two signs were ordered and shipped separately. The City of Lamar responded to the annual general license notifications and explained the 2nd exit sign was never received. No further information is available. The tritium exit sign that is lost was manufactured by: Best Lighting Products Inc. AKA Forever Lites, Model #SLXTU1GW20, Serial Number #318952, Isotope: H-3, Activity: 11470 mCi. Date shipped 2-3-2011.
The City of Lamar was not able to locate the contractor or electrician who worked on the project. Sign is reported lost. The remaining tritium sign will be tracked and annual reports to CDPHE, General License, will be sent in. Should the city decide to remove the sign, notification will be sent in to Radioactive Materials Unit at CDPHE.
Colorado Event Report ID No.: CO16-I16-25
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.
