| Title | Agreement State Report - Moisture Density Gauge Damaged |
| Event Description | The following report was received from the State of Maryland via email:
March 16, 2016 about 1600 [EDT]: [The GeoConcepts field representative] notified [the licensee's Radiation Safety Officer] (RSO) of the incident and that the gauge had been damaged. [The field representative] informed [the RSO] that a John Deere Dozer 700 had back up over the gauge. [The field representative], had just completed taking a compaction and moisture test. When the site foreman called to [the field representative] to ask about failing test results, [the field representative] placed the trigger lock back onto the gauge and walked over to the site foreman who was approximately 8-10 feet from where the gauge was located. The John Deere Dozer 700 operator was grading soil and placing it onto an onsite stockpile. The John Deere Dozer 700 operator proceeded to back up, in the vicinity of the gauge. When [the field representative] noticed the operator in close proximity to the gauge, he began to try and get the operators' attention. The operator was not able to see [the field representative's] attempts to gain his attention nor was he able to hear [the field representative] or the site foreman. At that time, the gauge was struck by John Deere 700, which resulted in cracking of the gauge case and breaking of the source rod. March 16, 2016 about 1620: The RSO called the assistant CS [Construction Site] manager and RSO, INC., to inform them of the incident and to immediately get RSO, Inc. to the site and address the issue. [The assistant CS manager] also placed a call to NRC and was informed to call Maryland NRC to notify them of the incident. March 16, 2016 about at 1630: The RSO, left our Ashburn [VA] office for the project in Maryland. [The RSO] arrived onsite at 1730 [EDT] to meet [the representative] of RSO Inc. RSO Inc. proceeded to perform a leak test and take readings of surrounding areas and construction equipment. [The source did not leak and there were no reports of radiation exposures.] March 16, 2016 about 1700: The RSO Inc. representatives were able to retract the source rod into the gauge case shielding. They packaged the gauge back into the carrying case; [The licensee's RSO] took the gauge back to the Ashburn office to secure it. March 17, 2016: The RSO, picked up the gauge and transported it to NETS (North East Technical Services), for the gauge to be disposed. The gauge is a Humboldt model number 5001 EZ, serial number 4704. The licensee is licensed in the Commonwealth of Virginia, VA License #45-25467-01 and MD Material License # MD-13-020-01.
