Abstract
Systems and methods for measuring natural gamma rays in a wellbore are disclosed that involve using a downhole gamma ray detector that provides signals that scale with energy deposited by gamma rays in the downhole gamma ray detector and storing digital signals in channels. A derivative of the digital signals is taken and the location of the maximum value of the derivative is used to stabilize the gamma ray detector by adjusting the threshold or gain based on the maximum value of the derivative or adjusting an amplifier or variable high voltage source. Other systems and methods are presented.
