Upon further investigation it was determined that the remote actuator on the device is inoperable due to a crack in the mechanism that holds the actuator to the gauge. This prevents the shutter from operating as designed by the manufacturer. The device is identified as Texas Nuclear, Model 5197 (Serial No. B1637) with approximately 100 mCi of Cs-137.
