The following information was provided by Kentucky Department for Public Health and Safety, Radiation Health Branch (RHB) via email: | |||
On Friday September 13, 2024, RHB was notified that an additional gauge was found at the recycling yard where the other two gauges were found. RHB personnel were dispatched on September 17, 2024 to secure the additional gauge. The gauge is stored at RHB in a secure location. | |||
On Thursday September 19, 2024 RHB was dispatched to a recycling center in Hazard Kentucky to retrieve two more gauges. A third gauge was reportedly cut up and disposed. Surveys of the area where the gauge was supposedly cut-up were conducted. Soil Samples were retrieved. Results are still pending, but no increased levels were detected. | |||
RHB has recovered five gauges. Three were confirmed by serial number to be from Revelation Energy. Two of the gauges no longer have serial numbers. All five are believed to be from Revelation Energy. The unaccounted sixth gauge is believed to have been cut up and sent to waste weeks ago. RHB went to the location where it was cut and took surveys and soil samples. Lab testing revealed only background radiation. It is not believed that the cesium was compromised. | |||
Five of the six gauges have been through one half life and the sixth has an original assay date of November 2001. | |||

THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL | 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.
