AGREEMENT STATE REPORT - LOST EXIT SIGNS
The following is a summary of information provided by the Colorado Department of Public Health and Environmental (the Department) via email.
The Department received a notification from AMC Westminster Promanade 24 that two exit signs with 10 Ci of H-3 were lost in Westminster, CO.
Manufacture: Isolite Corporation
Model Number: 880-12-6.
Colorado Event Report ID Number: CO250023
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.
