A
Troxler Model 3411
moisture density gauge was damaged when it was run over by a bulldozer at the Rydal-Waters construction site on Brooke Road in Abington Township, Montgomery County,
PA. The
gauge was left unattended and uncontrolled while the
gauge operator went to retrieve a vehicle to transport the
gauge. While left unattended, the
gauge was run over by a bulldozer resulting in the
gauge being broken and the instrument case being damaged. The sources remained in place in their rods. The rods were placed back inside the
gauge, and the
gauge was placed back inside its case. Soil surveys resulted in no spread of contamination. Radiation levels taken were not abnormal. There are two sealed sources inside the
gauge Cs-137, serial number 40-8387, 5.4 millicuries and
Am-241/Be, serial number 47-6341, 38.8 millicuries.
The licensee notified NRC (Sattar Lodhi, Region I ),
Troxler, and local authorities: Abington Township Emergency Responders and Montgomery County Emergency Management. The
gauge has been removed from the Rydal-Waters site to Advantage Engineering's Allentown,
PA. office.
Troxler is leak testing the
gauge and evaluating a transportation plan to return the
gauge to
Troxler's corporate location.
