1. A radiographic source exposure device, comprising:
a housing;
a radiographic source capsule within the housing, the radiographic source capsule having a radionuclide;
a shield within the housing and configured to shield the radiographic source capsule and to permit extension of the radiographic source capsule to expose the radiographic source capsule;
one or more sensors coupled to the housing, the one or more sensors configured to detect sensor data comprising one or more of: a count of exposure cycles, a length between the radiographic source capsule position and a stored position, a source decay of the radiographic source, a locking device locking mode status, an unlocking key status, a particulate count within the shield, a shock event, or shield wear;
a processing system within the housing and configured to store the sensor data and output the sensor data; and
a power source within the housing and configured to provide power to the processing system.
