AGREEMENT STATE REPORT - SHUTTER STUCK OPEN IN DAMAGED LEVEL DENSITY GAUGE

The following was received from KY Department for Public Health & Safety, Radiation Health Branch (KY RHB) via fax:

"KY RHB was notified by telephone on 8/8/19 by a representative from a specifically licensed facility, North American Stainless, that on 8/7/19 an event occurred when molten steel escaped a mold due to an overflow in a cooling trough, and covered access to the top portion of a Berthold Model LB300ML level gauge (Serial No. 9413), containing a 1 mCi Co-60 rod sealed source (Serial No 1820-11-5). This resulted in the shutter on-off mechanism becoming disabled. After the steel and mold had cooled, it was freed on 8/8/19 and segregated into a secure storage area.

"Initial readings taken with a Ludlum 2241-3 survey instrument measured with a Ludlum 44-7 probe were less than 2 mR/hr outside the gauge storage area. No overexposures were reported.

"On 8/8/19, Radiametric Technologies, a service provider located in Lorain, Ohio, requested reciprocal approval and was granted reciprocity on 8/9/19 in order to assess and remediate the situation, to be conducted on 8/13/19.

"North American Stainless is reviewing the incident to avoid future repeat incidents involving mold flow issues, and a complete report will be provided once the remediation is complete."

IRIDIUM-192 SOURCE LOST DURING SHIPMENT

A 0.78 Curie (today's activity) Ir-192 source was lost during shipment from the Mayo Clinic in Rochester, MN to Alpha-Omega Services in Vinton, LA. The last known location was Memphis, TN with the common carrier. Its original shipment date was February 8, 2019.

The licensee contacted the common carrier upon suspicion of loss on June 4, 2019. On August 7, 2019, the source had not been located and was deemed lost.

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.
