Title	Agreement State - Damaged Moisture Density Gauge
Event Description	The following information was provided by the Maryland Department of the Environment (MDE) via email: This report is made in accordance with 10 CFR 30.50 (b)(2). At 1045 EDT on 8/7/2024, an Instrotek 3500 nuclear density gauge (serial number 566), containing a 10 mCi Cs-137 source and a 40 mCi Am-241 source, was struck by site equipment (skid steer) during asphalt placement operations in Syracuse, NY. The gauge was licensed to, and being operated by, Kleinfelder, a Maryland licensee (MD-05-248-01) and used in New York under reciprocity arrangement. The base plate of the gauge was damaged, but there was no observable damage to the source rod and it was retracted to the safe position at the time of the accident. Kleinfelder contracted a third party to complete a survey and no elevated levels of radiation were detected. The gauge was then transported to the Kleinfelder office, located in Mechanicsburg, PA, and tested for source leakage. MDE was notified on 8/8/2024 at 1258 EDT and requested that the gauge be tested for leakage. Leak tests later showed no leakage of radioactive material. At this time, the gauge is returned to the licensee storage in Maryland and [placed] out-of-service. The State of New York also reported this event on August 8, 2024, under EN 57266.
