<p>An improved gamma controller health detection assembly to facilitate reliable downhole measurement of naturally occurring radiation is disclosed. The gamma controller assembly includes one or more gamma sensors, a micro-controller, memory, and input/output ports among other components. The gamma sensors detect radiation and output pulses that are received by the microcontroller. The sensor data can be checked, selected, and averaged by the microcontroller, and sent uphole to another microcontroller or computer that can then further process, communicate, and display the data. The sensor data can be averaged and stored to memory or stored as independent values to memory. The gamma controller health detection assembly can be configured to run algorithms that detect if one or more gamma sensors appear to be malfunctioning or have previously malfunctioned.</p> |
