Event Description: On May 14, 2010, Harsco Metals identified a failure of the shutter mechanism on a generally licensed portable alloy analyzer during the semi-annual test. The analyzer was a Niton model XLp818 (ser# 6500) with approximately 30 mCi (1.11 GBq) of Americium-241.

No individuals were in contact with or exposed to the direct beam during this procedure.
Cause of the Event: Equipment failure
Actions: The device has been taken out of service and Harsco Metals will contact the device manufacturer for instruction on returning the instrument for repair or replacement. PaDEP considers this a closed incident at this time.
