The following information was obtained from the State of
Colorado via email:
The general license section of the Radioactive Materials Program [at the Colorado Department of Public Health and Environment] sent out annual notifications requesting response regarding tritium exit signs reported in use at locations given by the manufacturer. Upon an audit of the annual mailing for non-responders, Elkco Properties & Olson's Greenhouse were contacted. After a complete inspection of the greenhouse and several confirmations, only 3 tritium exit signs remain in the facility. It is unknown as to the disposition of the lost 3 exit signs as further information is unavailable due to time of reporting loss. Elkco has plans to remove the existing signs and replace them with non-tritium signs. They will inspect each building they lease and should any tritium exit signs be found, follow the regulations in the Colorado Rules and Regulations Pertaining to Radiation Control.

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.
