DISCOVERY OF GENERALLY LICENSED GAUGE AT CAMP PENDLETON, CA On March 13, 1998, the Executive Secretary of the Navy Radiation Safety Committee informed Region II that approximately one week ago, personnel ct the Camp Pendleton Marine Corps Base discovered a Generally Licensed gcuging device in the facility sewer system. The device, an Ohmart Corp.
Model SR-1 (SSD'No. NR-522-D-881-B) was labeled as containing 500 millicuries of Cs-137 as of December 8, 1974. Shortly after it was discovered, the device was relocated to the low level waste storage area at the Camp Pendleton hospital.
On March 12, 1998, a Navy health physicist measured a dose rate of 45 millirem / hour at two feet from the device with the shutter open, and tested the device for contamination. No contamination was detected as a result of this test. The device shutter was closed and the device was returned to storage to await final disposition.
Initial information obtained by the Navy indicated that seven of these devices were installed several years ago at the facility as a part of the sewage flow indicator system. In approximately 1992, a new, nor.-radioactive detection system was installed and the radioactive davices were left in place. The Navy is investigating to confirm how many of these devices remain at the facility, the current status of any remaining devices, and to identify any safety concerns associated with j
the devices.
i This information is current as of 3:00 p.m. on March 13, 1998. Region II j
in monitoring the Navy's activities associated with this issue. Region IV will notify the State of California.
