| Title | Sealed Source Gauges Involved in a Fire |
| Event Description | The following information was provided by the Illinois Emergency Management Agency (the Agency) via email:
The Agency was contacted on February 3, 2023, by Jiva Resources in Sauget, IL to advise that five Cs-137 gauges had been impacted by a fire in September 2022. A Jiva Resources representative called and initially reported the five radioactive gauges as stolen 'in the last week.' When Agency staff returned his call that same morning, the devices had been located but were identified as having been involved in a fire back in September 2022. While the container (sealed drum) holding the gauges was impacted by the fire, it is unclear if there was any impact to the gauges. The devices include two Ohmart model SH-F1 gauges (serial numbers 2879GK and 1652GK) and three Vega model SR-A gauges (serial numbers 2174GK, 2878GK, and 63008). All contain 20 millicuries of Cs-137 except for serial number 63008 which contains 30 millicuries of Cs-137. It should be noted the SH-F1 housings are identified in the Sealed Source and Device Registry as being fireproof (rated above 800 degrees Celsius for 30 minutes) while the SR-A housings are lead-filled cylindrical steel shells, which are noted for retaining the source should the lead shielding melt out. Exposure rates should be less than 5 mR/hr at one foot - which will be confirmed by Agency staff. Leak tests will be conducted and source security assessed. Additional regulatory requirements regarding proper disposal, storage, leak testing and reporting will be investigated as well.
The following information was provided by the Illinois Emergency Management Agency (the Agency) via email: Agency staff attempted to perform a reactionary inspection the morning of February 6, 2023, to inspect the condition of the five radioactive gauges identified above. This effort confirmed that the registrant did in fact lose accountability of the gauges as it appears they were stolen at some point in the last four months. The last known location was in Sauget, IL in September 2022 when that storage location was involved in a fire. Since that time, the building has reportedly been accessible to looters. Local scrap yards and public safety partners will be notified. Illinois Incident Number: IL230002 Notified: R3DO (Szwarc) and NMSS Events Notification, ILTAB via email. 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.
