AGREEMENT STATE REPORT - STUCK SHUTTER

The following is a summary of information provided by the State of Georgia via E-mail:

Licensee personnel were performing three year wipe tests when one gauge was found to have a stuck shutter. The gauge contained a Cesium-137 source (Device: Model D14400S, S/N SE4029, Source; 250 milliCuries; S/N SNC250066). The gauge was not in service at the time of the wipe test. The licensee is planning on selling the gauge and having it removed from the premises. The company buying the gauge is aware of the stuck shutter and will fix the shutter before removing it from the licensee's premises.

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGN

The following summary was received from the State of Colorado via E-mail:

The licensee is unable to locate two tritium exit signs with an activity of 7.5 Ci each.

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.

STUCK SHUTTER

The following is a summary of the report received from the licensee:

On 4/7/2020 a trained technician was in the process of performing the bi-annual inventory/shutter checks when he reported that an Ohmart gauge (Model Number ED-6, Serial Number 65902, 100 mCi, Cs-137) located on 9B DTU (Deslime Thickener U/Flow) in the Deslime basement had a frozen shutter mechanism, rendering the shutter non-operable. The technician notified the Radiation Safety Officer who then instructed the technician to replace the gauge with the stuck shutter with a spare gauge. However, the replacement will not take place until the line it is on goes down for repair (estimated May 1, 2020). If the line goes down prior to this time, the licensee will replace the gauge at that time.

The licensee noted that they have had events similar to this in the past and have not had an exposure to any individuals. The licensee additionally noted that in the event of an emergency, the gauge will be removed, placed on a piece of lead and brought into storage.
