Licensee reported that several months ago, four (4) 'sensor units' on fixed GL [General License]
gauges it manufactures were involved in a fire at one of their customer sites in Painesville,
Ohio. The
RSO did not know the exact date of the fire. The sealed source used in these units is the
AEA, AMC, P1, 150 milliCurie
Am-241. Two of the units appeared burned and the other two appeared undamaged. The licensee had the customer do wipes on these which were negative. Then the units were shipped back to the licensee where they are now. On 12-08-03 the
RSO was disassembling the worst-looking one in preparation for shipment back to the source manufacturer,
AEA Technology. Wipes were done. The
RSO detected elevated readings up to 200 cpm (background is 2-3 cpm) from the burned area of source S/N 4382LX mounted on probe sensor S/N 2851 using a Ludlum Model 12 alpha meter.
Per the RSO, sources have been secured and contained pending further instructions. RSO indicated surveys were done of work area and personnel and no contamination was detected. The State is initiating an investigation and will send an inspector to the licensee for surveys.
The State reported that the
gauge is a model # 103.
