AGREEMENT STATE REPORT - PORTABLE GAUGES DAMAGED BY FIRE

The following information was received from the Commonwealth of Virginia by email:

"Event description: On May 23, 2016 a Virginia Radioactive Material Program (VRMP) inspector performed a routine unannounced inspection of Superior Paving Corporation. The inspector discovered that on April 20, 2012, two Troxler Model 4640-B Portable Gauges (serial numbers 1384 and 845) containing 8 mCi of Cs-137 each, were damaged by fire. The fire burnt the storage box which contained the two gauges. The transport containers and plastics on the gauges were melted. However, according to the Radiation Safety Officer statement, the integrities of the sources were intact. On May 10, 2012 the two gauges were transported by the licensee to North East Technical Services (NETS) for disposal.

"A transfer record was available for review. The licensee will provide the agency (VRMP) a detailed report for review. There was no public health exposure or environmental release from this event."
