Title	Agreement State Report - Shutter Stuck Open in Damaged Level Density Gauge
Event Description	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.
