The gauge was licensed to, and being operated by, ECS Mid-Atlantic, LLC (MD-21-037-01). The display and source guide handle was damaged but the part of the gauge containing the sources was not. The sources' shielding was not damaged. The source rod was successfully retracted by the Radiation Safety Officer (RSO) and several surveys of the area were performed by the RSO confirming only background radiation levels. At the time, the gauge was returned to the licensee's storage facility and tested for source leakage. MDE was notified and requested that the gauge be tested for leakage and the RSO's dosimetry be read. Leak tests later showed no leakage of radioactive material and the RSO's dosimetry read a minimal dose. At this time, the gauge has been repaired by the manufacturer and returned to service. the manufacturer and returned to service. +
