Abstract
Systems and methods for downhole component monitoring including a monitored component doped with a pre-selected neutron absorbent, the monitored component being part of a downhole tool and a neutron monitoring system positioned relative to the monitored component. The neutron monitoring system includes a neutron source positioned at a first location relative to the monitored component and a neutron detector positioned at a second location relative to the monitored component, the neutron detector configured to detect neutrons from the neutron source and count said detected neutrons. A control unit is in communication with the neutron detector and configured to determine a status of the monitored component from the neutron count received from the neutron detector.
