Title	Agreement State Report - Damaged Co-60 Caster Gauge
Event Description	Received the following report from the State of Ohio via email: At approximately 2000 [CDT] on 8/16/2010 a molten metal overflow event occurred at Charter Steel. Molten metal flowed down a tube outside the crucible where the caster gauge is located. The caster gauge, a Berthold LB300MLT containing 5 mCi of Co-60, was covered in molten metal as a result. On the morning of 8/17/2010 the licensee's environmental contractor was called to help assess the situation. Radiological surveys were conducted and no contamination was found. The gauge manufacturer recommended that the licensee contact Radiametrics (Ohio license # 03225480000) to recover the gauge. Radiametrics responded on the afternoon of 8/17/2010. Ohio Department of Health dispatched an inspector to investigate the incident and observed as Radiametrics removed the gauge from the now solidified block of steel. The gauge was found intact and the shutter was found in the closed position. Radiation surveys indicated that the source was intact and was not leaking. At approximately 1400 on 8/17/2010 the gauge was placed in secure storage at Charter Steel. The licensee has contracted with Radiametrics to transfer the source to a new Berthold gauge when it arrives in the next few days. Ohio Incident # OH100010
