1. A sucker rod cleaning system comprising:
an induction heating device including an electromagnet comprising a wire coil head configured to inductively heat an electrically conductive sucker rod positioned within a heating zone of the wire coil head;
a sucker rod feed mechanism configured to feed a sucker rod through the heating zone of the wire coil head in a feed direction; and
a radiation sensor positioned on a downstream side of the inductive heating device relative to the feed direction and configured to generate a sensor output that is indicative of a level of ionizing radiation being discharged from the sucker rod.

13. A method of cleaning scale deposits from an exterior surface of a used sucker rod using a sucker rod cleaning system, which comprises an induction heating device including an electromagnet comprising a wire coil head having a heating zone, a sucker rod feed mechanism, and a radiation sensor, the method comprising:
feeding the used sucker rod in a feed direction through the wire coil head and the heating zone using the sucker rod feed mechanism;
inductively heating a portion of the used sucker rod within the heating zone using the induction heating device during feeding the sucker rod;
discharging the scale deposits from the exterior surface of the portion of the used sucker rod during inductively heating the portion; and
generating a sensor output using the radiation sensor that is indicative of a level of ionizing radiation being discharged from the used sucker rod at a location that is on a downstream side of the inductive heating device relative to the feed direction.
